Last Updated: January 8th, 2013

We all love Android, and we also love when Google releases a new iteration of our favorite mobile OS. Sometimes, though, even Google screws up a bit, and Android 4.2 is looking to be one of the most bug-ridden releases since Honeycomb. And, let's be honest: 4.2 isn't exactly the leap that 2.3 to 3.0 was, either. Chances are, if you're on Android 4.2, you've experienced at least one of the issues here. Some aren't that bad, but some can just ruin your day, and we're a little shocked Google missed them.

We'd love it if you could confirm whether these bugs happen on a device not listed as "known affected," or of any other serious issues you've been experiencing since the bump to 4.2 on your Nexus.

Auto-Brightness Bugs

Known affected devices: Nexus 7, Nexus 10.

Documented? Android bugs [1] [2] [3], XDA, Google+.

This bug isn't one I've experienced personally, but many, many others -including Artem - have. After the Android 4.2 update (or just on the Nexus 10, in general), auto-brightness behavior has been less than reliable, particularly on the Nexus 7 - though that device's problems aren't strictly limited to Android 4.2.

The issue specific to the Nexus 7 causes the screen to noticeably flicker when set to auto-brightness, and has been present on all Android builds, especially at low levels. With the Android 4.2 update, that behavior has apparently gotten worse. Yikes. Which leads us to the generic auto-brightness bug.

Auto-brightness in Android 4.2 seems to randomly adjust with no changes in ambient lighting, as though the sensitivity is too high, or some sort of other software glitch is causing the brightness setting to suddenly drop, then come back up to the appropriate level. Basically, auto-brightness is borked. While I never found auto-brightness on the Nexus 7 was good in the first place, many are now complaining it is much worse, and on the Nexus 10, as well.

Bluetooth Is Basically Broken

Known affected devices: Nexus 10, Nexus 7, Galaxy Nexus.

Documented? Android bugs [1] [2], XDA [1] [2], Google+.

We've already received numerous emails about this issue, and I've confirmed it myself: Bluetooth on everything but the Nexus 4 (apparently) is in an absolutely sorry state right now. Audio streams extremely choppily, sounds mediocre, and often loses connectivity entirely. 3rd party Bluetooth apps that create compatibility with devices like the Sixaxis or Wii controllers no longer function at all, and throw an error instead.

This is bad. This is the kind of thing that makes someone return a phone or tablet, because A.) people have no patience for stuff like this, and B.) there's zero reason something as simple as Bluetooth should be broken so badly out of the box. Google needs to mark this one "critical" and fix it ASAP.

Random Reboots / Major Instability

Known affected devices: Nexus 10, Nexus 7, Galaxy Nexus, Nexus 4.

Documented? Android bugs [1] [2] [3] [4] [5] [6] [7], XDA [1] [2] [3], Google+.

File this one under "critical," as well. I myself have experienced this bug - my Nexus 7 rebooted no less than 4 times this weekend, several when it was just sitting idle with the display off. That's... bad. I've since done a factory reset, and in the last hour, so far so good. You'd think a problem this serious would be limited to a pretty specific subset of hardware, but no - everything but the Nexus 4 is affected (which seems to be the case for every one some of these bugs, oddly) all Nexus devices appear to be affected (thanks for the input about the Nexus 4, guys). The reboots occur when opening webpages in Chrome, using Play Magazines, and a variety of other circumstances (like doing nothing at all).

Nexus 10 users are apparently the most-irked when it comes to the reboot issues, with them often occurring multiple times a day. The behavior described sounds a lot like a kernel panic - total system lockup while in the middle of a task, followed by a soft reset. Video playback seems to be one suspect for these lock-ups across all affected devices, with the YouTube app having been cited several times in various postings.

The reboots aren't the only problem, though. On Galaxy Nexuses and Nexus 7's (eg, devices upgraded from Android 4.1.2), performance has taken a complete nosedive. Opening apps, Google Now, or navigating through the UI has become much slower in some cases. I noticed this when I upgraded, too - all that butteryness suddenly got a little less smooth. However, after a factory reset, I noticed marked speed improvements in the UI generally. Personally, this is where I immediately go if I'm having performance problems (and haven't recently installed a new app). There's no use in complaining about it if you haven't tried it already, because that's just what Google's going to tell everyone to do eventually.

However, many posters in various Android bug threads are reporting that factory resets don't alleviate any of these issues - which is highly concerning.

The stability problems don't end there. Galaxy Nexus owners are saying that their phones' displays are randomly turning on without any interaction. The system clock's time is off by anywhere from 3 to 10 minutes when set to "Network Time" for some. Apps are force closing for no apparent reason. For an incremental update, Android 4.2 sure seems to be causing all the problems associated with a much more significant OS release.

Extreme Battery Drain / Slow Charging

Known affected devices: Galaxy Nexus, Nexus 7, Nexus 4.

Documented? Android bugs [1] [2] [3], XDA [1]

This is really two separate issues, but they both fall under the "my battery makes me hate my life" umbrella, so I'm lumping them together.

The first one is battery drain. I (and others) have noticed Google Play Services has absolutely eaten into my Nexus 7's battery life post-Android 4.2. Usually, I get a solid 3-5 days of standby time if my Nexus 7 is sitting mostly idle, but after leaving it alone this weekend for under 48 hours, I returned to it at about 8% remaining. Not good. Similar issues have been brought up by Galaxy Nexus owners. In addition to that, exchange accounts are apparently causing massive loss in battery longevity. The exchange issue can be alleviated by removing and re-adding your accounts, according to some of the bug threads.

The Google Play Services problem, though, doesn't seem to have a solution presently, and reportedly is affecting all Nexuses. I'm also hearing from numerous people that NFC is causing extreme battery drain in some cases across all Nexus devices, a problem I, too, have experienced.

The second issue - slow charging - is specific to the Nexus 7. For now, there seems only to be an XDA thread acknowledging its existence, but both Artem and Cameron have been able to replicate it on their own devices since the update. The issue is quite simple: the Nexus 7 charges really, really slowly. It happens intermittently - sometimes it will charge quickly, sometimes not. Which to me suggests some kind of issue with the operating system recognizing the amperage of the charger, and going into "slow charge" mode (eg, over USB) at 0.5A when it should be at 2A (standard USB wall charger).

Lockscreen Widgets / Camera App

Known affected devices: All Nexuses.

Documented? Android bugs [1] [2], Reddit.

The newly-implemented lockscreen widgets have gotten off to a bumpy start, with numerous bugs and glitches affecting them across all devices. Lockscreen music controls for Google Music are randomly disappearing if a 3rd party music app is started, stopped, and then Google Music is started again, not reappearing until the device is rebooted. And the widget, if the system decides to kill the music app the widget is linked to, causes very strange behavior to start occurring on the lockscreen.

The camera app also has a minor problem when rotating from portrait to landscape mode, taking up to 3 seconds to rotate depending on the device. Instead of simply rotating the button arrangement, the entire display rotates, causing substantial lag in the app.

These last ones are quite minor, but they're generating quite a lot of complaints at the moment.

December Is Missing!

Known affected devices: All Nexuses

Documented? Android bugs [1], AP

It looks like in its haste to finalize 4.2, Google forgot something pretty major in the People/Contacts app: December. Yes, they omitted an entire month. Oops.

Anything Else?

Any other weird happenings in Android 4.2 that you've found? We've intentionally skipped over some of the smaller ones, but feel free to chime in about anything you've discovered - particularly if one of the issues above is affecting a device not listed (stock Nexus devices only - custom ROMs just add too many variables).

    Whenever I leave Wifi connected for a long period of time, I get blocked from Google Services. Turn the phone on and note the grey icons. Turn off Wifi and as soon as phone goes back to 3G I start getting emails again. Had Galaxy Nexus since January and it did this immediately after 4.2 update.

    • Mike

      Same exact wifi issue on my Nexus 4. Happened 5 times today.

  • http://ahylianhuman.me Rod Davis

    I had the battery drain issue today. Everything was fine all weekend, but today, "Google Services" took my battery for a nose dive. Pulled out my phone earlier today and was surprised to see "Plug in your charger" on my lock screen, and 16% battery left.

  • bos

    Didn't even notice the bugs. The arbitrary UI changes were annoying enough to drive me back to 4.1.2. For example, the notification bar change is annoying as hell. It's like a caricature of what settings toggles in the notification area should be. It makes the notification drop down less intuitive to use, and doesn't even provide actual toggles or any real functionality.

  • Swapnil Chitnis

    None of the issues mentioned above (Motorola Defy with CM10.1 alpha)

    Lag in lock screen rotation, when camera app is opened from lock screen and used in landscape mode. The lock screen is displayed in landscape mode for 2-3 seconds. experiencing this in Galaxy nexus after upgrading to 4.2

    in all 4.2 roms im getting weird call bugs, when i get a call the phone keeps vibrating even after picking it up or when i cut the call it still vibrates .. quite frustrating

  • Seth Daniel

    My Galaxy Nexus on t-mobile has been flawless on 4.2 I've been running it since the first day the OTA came and have had absolutely no reboots, no problems with battery life, in fact I think it's better, no problems with bluetooth (I use it everyday to listen to music on my way to work). I don't use the camera much, I opened it a few times to play with the new features, but don't use it enough to really comment on that bug.

    December is, of course, missing in the contacts app, but that's an easy fix and I'm not worried about it. I'm curious if anyone has any December birthdays or anniversaries already in their contacts, what happens to those? Do they show up properly? Or do they show January or something instead?

  • jathak

    I have noticed the screen flickering on the Nexus 7 a bit, but not really any more than on 4.1. Stability has been fine on both my N7 and my VZW GNex, although battery has been a bit worse on the N7 (my phone was already bad in the battery department).
    Haven't had any issues with Bluetooth though.

  • shonangreg

    Bluetooth audio sounds like a machine gun for me. Also my compass still does not work (N7).

      "-gate" is too mainstream.

        I was using -gate before it was cool. i use a new suffix now. it's pretty underground, you wouldn't have heard of it.

    Only issue I've had on Galaxy Nexus GSM stock Takju 4.2 is when I made an alarm for today at noon, silenced the alarm, and deleted it afterwards. However, the alarm is still showing on the digital clock widget. Adding a new alarm doesn't get rid of it. The only solution is to either reboot the phone or delete and re-add the widget. I can consistently repeat the issue on my GN and a coworkers. See: http://imgur.com/taAz6

  • Mark Barrios

    On my Galaxy Nexus, I also experience the lock screen sometimes being unresponsive. I use the pattern lock screen and at times it won't respond to touches. i have to hit the power button to turn the display off and on again to get to respond.

  • Chuck

    Wi-fi all of a sudden started dropping so frequently. have read it on a few sites. anyone else?

    • http://twitter.com/davidecassenti Davide Cassenti

      Might be related to the "Wi-Fi optimization" setting in the advanced option. It looks like disabling it helped me, although I have most of the other issues above.

  • Wibbly

    Device wakes up (screen on) once an hour exactly. Probably an app problem but it didn't happen on 4.1.2 I WISH Google didn't keep changing their APIs. Google, ever heard of backwards compatibility???

  • http://www.facebook.com/OriginalName3 Paul Walsh

    Turning the screen on and off takes an extra half-second now on my galaxy nexus. It doesn't seem like much but sometimes I forget about the delay and hit the button again, making the screen turn on and instantly off again.

    It's really frustrating.

  • JJ

    Here's another annoying one:
    - go to Gmail and set notifications ON, but vibrations OFF
    - set the phone to vibrate mode
    => when you receive a notification, the phone vibrates
    This was not the case in Android 4.1 or older.
    So it's a bug orvthey've changed the behavior so that the phone settings be more important than the apps settings.
    It wouldn't be the first time that Google changes something that is ok into something very annoying (e.g. switching the OK/Cancel buttons... right handed people hate that change).

  • http://twitter.com/belgianatheist Hugo

    no problems with Bluetooth on (rooted stock) Galaxy Nexus with 4.2 here since last week Thursday.
    I make calls and listen to hours of podcasts with BeyondPod every morning and evening, my BMW and my wife's Audi have no problem with my GN, no choppy sound, the only thing is that when I switch to radio the podcast keeps running, it didn't used do that.

  • Thomas Seeling

    I made the mistake to use the notification bar while a new user was connecting to google.
    To be precise: I created a user for my wife, she entered her gmail and password, then waited for the login process to complete. During that, the notification bar showed something about user dictionaries. I followed the notification and was placed in a settings dialog, but without the buttons for "back", "home" and "last apps". So I could go forward a screen, but I could never leave the settings.
    This was persistent, even after I switched off and rebooted. The new user still had no menu buttons. I deleted the user, created it anew, did *not* follow the notification, and the user was ... usable.

  • stephan celis

    I had some random reboots on my Samsung Galaxy S3

  • wjohnburgess

    Why is there no official response to these problems. Someone at the top of the Google/Android tree should be owning up and apologising. This upgrade was obviously rushed out with no proper testing. We poor Nexus 7 owners are being used like laboratory mice, as test animals for something that is not even at Beta stage. I've been slagging off the all pervasive Apple world recently and now I'm thinking of joining it. Higher prices are worth paying for reliability. I want my Kobo App back and Norton protection now. They should re-issue 4.1 as an interim measure and clean up 4.2 before releasing it again.

  • Paranoid

    This story was cooked up a Microsoft Rep to undermine the issues they had with the Windows Mobile 8 launch. I contest the claims in here. No Nexus devices have the complaints put up here..It's a conspiracy.. ;)

  • Nolene Ferrari Naidu

    Galaxy Nexus: The Gallery app has a terrible lag since the upgrade. The Play store gives errors such as: Error: No connection, while other applications are connected just fine.

  • Reyes Cedeño

    I flash a fatory image and I don't have any of those bugs, the bug I found was one related with the web browser. I love use the quick settings option and now it makes the internet surf really bad, its laggy and the loading bar looks weird.

  • http://twitter.com/Michael97F Michael Fordham

    I have had a few problems since going from Android 4.1.2 to 4.2 on my Nexus 7. First, the brightness keeps going up and down. Also, something that was present in 4.1 was, after you watch a video, when you go back to your usual apps, the colour contrast is blinding, is anyone else noticing that?

    One of my Bluetooth keyboards won't work but that could be down to low charge. I hope they push out an update quickly because I actually miss 4.1.

  • Hardik

    star at above page to bring it to notice of google if u have the same issue

  • http://www.facebook.com/profile.php?id=1745689461 Hal Motley

    I would honestly expect bugs like this on a nightly release of an Android ROM (notably CyanogenMod). To me it seems that Google have been pushing this release too hard in time for the Nexus season in Q4 and haven't done a reasonable amount of testing or had time to fully address the issues.

    Android 4.2 does look badass, especially with the new clock app (and widgets) but I really don't want an official Google stable release behaving like a nightly.

    However in a worst case scenario maybe we'll see another million to the CyanogenMod userbase! XD

  • http://www.facebook.com/profile.php?id=1745689461 Hal Motley

    There should be an option called "Android 4.2? I am still using Android 2.3!".

    bluetooth works perfectly fine for me on my galaxy nexus, i use it to stream music in my car, The performance also significantly increased for me. Its noticably smoother but I did a clean flash rather than an upgrade which might be the issue

    Take a picture from the Camera Screen Widget, then try to upload it anywhere using the gallery from the camera widget; it just freezes. Nexus 4.

  • Robert Caldecott

    I updated my Nexus 7 to 4.2 at the weekend. Last night I had my first lock-up while attempting to install some app updates from Play Store while streaming music from Google Play Music. The system just froze and I had to reset it. This is my first issue since I got the N7 back in July.

    And the auto-brightness is a mess - it flickers, darkens/lightens for no apparent reason but at least it can be disabled.

    And that music streaming ... it stutters and burps when attempting to use the network for anything else, even a simple Twitter update, and I have plenty of bandwidth at home. This worries me greatly as I am going to be relying on streaming music to make up for the lack of device storage!

    It's much better on my new Nexus 4 though although on the first day with the phone Google Play started to burn through CPU/battery and the phone got quite hot. A reboot fixed it and it hasn't happened since.

  • SaltwaterC

    If it's not broken, fix it till it is. This article came a little bit late. On my side of the problem, there's issues with the auto-brightness, battery drain, and charging. Not the slow charging issue, but the NO charging issue. Had to unplug the cable, then connect it again last time when my N7 was yelling for the charger. It just sat there, doing nothing, draining the last six percent of the battery. Initially I though that it was an user error, but the micro USB cable was properly inserted.

      was thinking the same.. not sure why. Asus uses a 3rd party type of server app.. not sure why we never added one to the N7..its to stream back and forth.,Wifi Direct is limited and they dont speak about its function much.

  • James

    I have been having problems with 4.2, random crashing (of the launcher), sometimes slowness / lag tends to happen on the home-screen as well which can take up to 10 seconds before it goes fast again, and I've noticed lag throughout the entire device (not sure if it's the multiple user thing)

    I use a nexus 7 with android 4.2 jelly bean. :(

  • Brenton

    It likes to completely forget I just dialed a number and clicked call. It'll bail out to the home screen and do nothing. Redial doesn't remember the number either.

    Also, sometimes I'll spend far too many seconds looking at a Calling with Google Voice modal that I'd never seen before upgrading.

    For what its worth, Auto Brightness has sucked on Android for a while now. Ever since ICS, it is always more dim than it should be for the lighting conditions Thankfully there are custom ROMs to adjust these settings (or LUX in the App Market if you don't want to deal with a ROM).

    I just found a way to make the Nexus 10 reboot with click! I've connected the Bluetooth keyboard, set in the settings two languages for it (English US and Italian). It says to click "control+space" in order to switch languages. As soon as I do it, crash!

  • imok

    My screen saver now has an extra rectangle shape (upper left) that wasn't there before. The screen clarity (graphics) is less than it was prior to the upgrade. But the clarity seems to be fine, at one inch from the top and one inch from the bottom of the screen. The area in between is less than normal quality. Also the tablet seems to become very warm while in use. (without the charger plugged in)

    No developer options in the phone settings ?

    No gallery option in the camera app? I personally like to view what I have clicked ! Or just quick access to gallery .

    Why would I have a gmail widget on the lock screen ? Isn't the home screen enough?

    Why isn't the Bluetooth working ?

      There are developer options, but they are not easily found like in previous versions, google it or check AP's old articles, to see where it is now.

    Amazon App Store - won't store login info, must login when opening any app from Amazon's store. Wonder why Google didn't test this more?

    Starbucks - app force closes on open after you have logged into your Starbucks account. This can be blamed on Google giving out too much free coffee at HQ :)

    • Mike

      It isn't Googles fault or job to test every app, but they do fall down here as they do not provide early releases to the developers to make sure their apps work with the upcoming Android OS updates. They have done better in the past on this one, this one seems rushed. Amazon pushed out an update today that fixes their login issue.

    "Galaxy Nexus owners are saying that their phones' displays are randomly turning on without any interaction"

    I got this issue on Galaxy Nexus running Android 4.1.2, not 4.2. version. It is gone now, most likely because I uninstalled several unnecessary apps - so it's probably a bad app, not Android itself.

  • Jesusv3512

    Two nights in a row now, my nexus 7 freezes a bit when charging, then I turn it off, with the charger still plugged in, and the charging animation comes on the screen. Then I try to turn on the tablet and it freezes on that charging animation. The only fix I have found for this is to open the back and take out the battery, which isn't an easy task on the nexus 7. After I do this, the tablet runs fine. Until the next night, the same thing happens.

  • Thorfinn

    One issue that reared it's head on my N7 was a touchscreen lag. I finally tracked this down to an accessibility feature that lets you tap 3 times to zoom any screen. I love the feature, but it renders anything needing a responsive control utterly useless. If this is unavoidable they need to add a on/off shortcut to the pulldown.

  • Rol

    The gyrosensors are calibrated incorrectly and there is no way to calibrate the sensors in the android-system! We need a bug fix for this!

  • Barratis

    Since I updated to 4.2 on my Galaxy Nexus, Android refuses to take in account per app settings for notifications, it only respects the global one. Which mean I get a vibration every time I receive a mail, a gtalk message or something else. The only way to deactivate it is to put the whole system in silent mode which make it easy to miss calls.

  • ArtC1

    Since the factory reset I performed the day after the 4.2 upgrade, the random rebooting has stopped. My biggest issue is the inability of the Amazon Appstore to remember my account information. When I attempt to use apps downloaded from Amazon, I am instructed to enter my Amazon information. In addition, I have noticed a large increase in lag time. I think Google would be doing a great service to its consumers by listing a means to reinstall 4.1 until they fix the obvious issues with 4.2.

  • Quan

    I am experiencing EXTREMELY slowed down times for charging when USB cable connected to a PC with my 4.2 Galaxy Nexus. It took me an hour to get from 7 to 16%. It's slooooow, and it wasn't like this before the 4.2 update.

    • http://www.facebook.com/profile.php?id=1065971454 Andrew Hime

      Had this the other day at work on my Nexo 7 - it was taking about 6 minutes per 1%, but I had never USB charged from a computer before and paid any mind, so I figured it was just because it's generally slower.

    The auto brightness bug happens on the Nexus 4 as well. I noticed it while playing a game in a pitch black room.

  • smithj33

    Google is learning that controlling hardware and software is no easy task. It took apple a while to get this near perfect. It takes time, patience and money. Android users are not as patient as apple users so you get things like 4.2.

  • B

    I am facing the ever existing issue of low speaker volume on galaxy Nexus even worse with 4.2 now.

    • Mike

      Tried a speaker call last night and thought it was worse than ever on my G-Nex - dang, this thing has so many new/worse issues!

  • Mark

    I have an odd one, when I goto do a data transfer to my pc's, tried Windows and Linux boxes, the older files I downloaded with 4.1.2. show up just fine. But none of the ones downloaded under 4.2 show up at all...I can access those files through the tablet itself but not a computer. Only way to transfer files now is to go slow and buggy Bluetooth. I also have a lot of apps that really hate this new update, as well as noticed it being very laggy and needing to power cycle it in order to make it work, until it boggs down again.

    Nexus 7 - 4.2 . my Wifi seems to not working at all. Be it with my home wifi, nearby hot spots or even tethering from my Galaxy Nexus. Found some article in the net to remove my current account and reboot n start over. Will try it after i get back home.

  • Nate Swanner

    I have an issue with my Nexus 7 randomly switching to landscape when being viewed in portrait. It simply switches, then switches back. No rhyme or reason.

  • Shanghai Jacket

    Nexus 7 requires multiple attempts to unlock using the pattern lock. Also the clock font/letter shape looks stupid now.

  • Arpit

    You forgot the damn WiFi stability issue. Many bugs are logged one of which is below.

    My Nexus 7 keeps turning on the screen when it's locked.

    Every 10-15. minute, the screen lightens up... No messages or anything.

    Here are some minor but very annoying bugs. Gallery is laggy, camera is laggy, whole UI is slower... Yesterday i ´ve got "system UI not responding"

  • xridder

    #bug: I use to send or play sound clips over twitter or whatsapp using dropbox public links. When I clicked a sound link, my nexus opened web browser and then popup music player.

    Now, in 4.2, when i click on sounclips link, it opens web browser and close inmediatly. I try this on both whatsapp and tweetcaster and it does the same thing. Might be a bug on web browser cuz it doesnt happen using dolphin as default.

      I meant direct links to a media file: like .mp3 .aac ...

  • Scott Laleman

    Of everything listed here, I've only seen the camera problem. However, I have my phone set to vibrate mode the majority of the time, with gmail set to vibrate "never," and now it vibrates every time I get an email. It's driving me crazy because I think I have a text every time it happens.

  • Confused Nexus Fanboy

    Not really a bug, but really annoying since 4.2:

    The audio-is-to-loud-warning that can NOT be turned off. It appears every now and then when you increase the loudness while using headphones. X-(

  • roberto

    The only thing occurring on my Galaxy Nexus is the delay in camera app when rotating from portrait to landscape. altough it is not taken 3 secs, maybe 1-2 secs, never longer.

    • ganesh4796

      Same here

  • Buzzard

    I fixed the Bluetooth on my N7 by doing a hard rest on the N7 (power off, then hold the power button down until "Google" appears the second time), then unpaired the Bluetooth devices and paired them again.

  • Simplastic

    HELP! I can't use my Nexus 7 at all any more. It says it's charging but isn't and switches itself off. Might hang it on the wall and use it as a mirror...

  • http://twitter.com/poorcku prk

    The volume when listening music is too low. This was changed with 4.2. Now I was asked If I was sure about listening to music so loud. It is definitely changed for the worse. PUT THE VOLUME BACK!

  • plr19

    On my new Nexus 7 (Android 4.2) when the screen brightness dips the Wi-Fi received signal also dips in sympathy - with the tablet immobile. Try putting your finger tip to momentarily sheild light falling on the camera lens!

  • harrydevlin

    The update from 4.1.2 to 4.2 bricked my Nexus 7. This may have been caused by something on my rooted Nexus 7, though the upgrade from Ice Cream Sandwich to Jelly Bean 4.1.2 worked fine.

    I managed to boot into recovery mode and I manually loaded 4.2. It was hopeless because of the battery charging issue. I didn't keep 4.2 long enough to check on the other problems that have been reported. I went back to 4.1.2 and installed FOTAKill.apk to stop the endless notifications that an upgrade is available.

    I use StickMount, which 4.2 broke, but now the app developer has updated the app to make it work with 4.2.

    Updates are not always good things.

  • http://www.facebook.com/dustintravis Dustin Travis

    On my Galaxy Nexus phone when I'm searching for stuff via voice it seems laggy. That is, the interface lags behind, and the results are jittery. Hard to explain, but definitely something different than from 4.1. A lot of times I grow impatient, click the microphone, speak again, but it then finally responds to my first request. Something's up.

  • neil

    Not so much a bug, but more of a missing feature, before jellybean you could drag the notification drawer down and while holding it halfway down you could use another finger to swipe away notifications, then just flick the drawer closed again... Now you have to drag it completely open and release it before interacting with the notifications at all....

    Am I the only one whose GPS seems to always be running in the background throughout the day? I assume it's the reason Google Services shows such a high battery use. Even when no app is actively requesting GPS it seems to be polling for it. Happens on Gnex and Nexus 7.

    • Neil

      Google now periodically checks your location if you have it enabled. Or is it on constantly?

      • http://twitter.com/tobiasly Toby J

        Ok that's kind of what I figured but it seems to be quite often & I'm surprised it wasn't mentioned specifically under battery issues.

  • http://twitter.com/sergevanneck Serge van Neck

    I'm also having way more WiFi issues. Sometimes while streaming Netflix it just quits and I can't even load a website until I turn WiFi off and on. This was not an issue before 4.2.

  • Tech Support

    My Nexus 7 randomly turns the screen on a few times per hour since the 4.2 update. Annoying since it's next to my bed and used as an alarm. Also, the new lock screen tries too hard to let you know that you can add more than just the clock, constantly showing the "add gadget" icon halway offscreen.

  • mialeo

    For me NFC is not causing any drain because it ils disabled by default and canot ne enabled....

  • ChristopherRogers1991

    I've had reboots happen the last two times I've tried to install updates, as well as several others that seemed to happen for no reason at all. Other regressions are what made me Google these issues, which brought me here. Glad to know I'm not the only one experiencing these issues. Hopefully we'll get an update soon to take care of some of these things.

  • jessl

    Where did the battery status indicator on there Nexus 7 lock screen go? Why is the developer option hidden? Why does the Nexus 7 boot with developer options enabled after cycling power? Why has zoom gone quirky? This is a 4 month old unit...

  • MrFloppy

    New Bug in Lockscreen found! Add in the Clock App the timezone for "Brasilia". Normaly under the Clock it shows you the time for the iother timezone "Brasilia".
    At the Lockscreen the Clock is without the new timezone, swipe to the right (add new widget) and than left to the Clock again the timezone for "Brasilia" is now there!
    Bug or feature???

    Greetings from Germany MrFloppy

  • Mat

    I have a Nexus 7 which I absolutely love - great piece of kit. 4.2 has changed it to a battery-draining, laggy, buggy, slow thing, more akin to my old HTC Desire HD. The lock screen is terrible, wifi keeps dropping out and the division of the notification shades (into notifications and "quick" settings) just doesn't work. Wish I could undo the install - very poor.

  • avanthomme

    What the heck Google!!! Why so many bugs. I loved my N7 prior to update. I showed it off to everyone I knew. Now, at Thanksgiving, as I sit with my Apple loving in laws, I feel like the budget tablet is showing perhaps budget quality as they blaze through their home screens with ZERO lag. As much excitement I show regarding Android products, I think I will have to slide this one away...don't want to confirm the in laws perspective on Google, when I know this is a fluke...let us easily flash back to 4.1.2 please!!! And please explain WTF happened....;(

  • disqus_ckr7qVZNP0

    only december issue but everything is so cool especially the photo sphere thing! however i am so much sure that google will fix it very soonly as apple fixed their very bad ios 6!

  • disqus_ckr7qVZNP0

    google will fix all of those very soonly! it will be again the best os ever! however thanks android police for listening to all of us!

  • http://codytoombs.wordpress.com/ Cody Toombs

    With this many comments I doubt this will be seen, but I want to confirm that there are charging/draining issues on my Nexus 4 and I've spoken with at least 2 other people who can confirm it. I've plugged it in to a wall charger that I know to work at 2.1 amp. Sometimes it charges at a rate of about 25% per hour, other times it charges at about 5-8% per hour. I've also seen intermittently high battery drain, which I suspect is tied to the same issues.

    I'm not having problems with random reboots on the Nexus 4, but I've watched my Nexus 7 reboot at least 5-6 times, and that's just when I was looking at it - I'm not sure how many times it's happened when I didn't notice it.

    There is, of course, also the sign-in error, but I'm sure that is unrelated and will go away soon enough.

  • Tyler

    My Nexus 7 tablet has TERRIBLE battery life now. Also, there are some apps that constantly try to download updates and never go anywhere (most likely the app developers fault and not Google...) But overall the new 4.2 seems very slow, clunky and it takes forever to open up certain apps (Chive, internet, youtube). Why did Google take a step back with this update??? Please get this right ... Please!?!?!/

  • http://www.facebook.com/brassman75 Dan Shernicoff

    I've been experiencing random and intermittent problems with the touch screen on my new N7 32GB WiFi. I'll start an app (usually one of the built in ones like email or people) and suddenly the screen won't respond. When I turn off and back on (the display - not performing a reset) everything comes back to normal.

    About the auto-brightness, I think it's a problem with the sensor. I use Lux to control my brightness and it usually does a good job - on my SGS running CM10 I have no complaints - but occasionally it will be very dim and trying to force it to take a new reading doesn't help. Again, turning the display on and off seems to help this.

  • rickyro

    Doesn't have that same butter smooth performance that 4.1. Definitely some noticeable lag

  • mometan

    On Nexus 10, every now and then the WiFi gets disconnected and I need to turn the WiFi off and on to get it back working. If I leave the tablet to charge, the WiFi disconnects (surprising since there is no need for extreme power conservation policies while the device is connected to power source), and then it does not connect automatically. I need to turn the wifi off and on again.

    • Tomi Golob

      Try turning off "optimize WiFi power" under advanced settings

  • sagar

    On Nexus 7, keep getting an error message saying unfortunately clock has stopped working. Clock is working fine, but error shows every 2 mins. Worthless device now

  • gapecans

    Videos are no longer saved. Seems to work when started but says video can not be played. Very bad this Thanksgiving with the family. :-(

  • Joe Generic

    I like the old clock app better, it was more elegant and clean. Now the alarms is full screen and it looks third quality...sigh....4.2 screw up. Funny, I'm the guy that makes fun of Apple...now Apple makes fun of me. Why you no fix Googel?

  • http://twitter.com/Darion__ Mohammad

    Other issues lag extreme lag when I press the power button to lock my galaxy nexus screen. It takes like 1 full second to lock the screen after the press. It also lags when i press the recent apps button and swipe off the apps.

  • Pilgrim

    Leap WiFi is broken in 4.2. Can't connect to corporate wifi. Had to roll back to 4.1.2 because of that.

    Performance on Nexus 7 on 4.2 is much worse than on 4.1.x

  • tonyodx

    I have a lot of problems with my Galaxy Nexus very slow a lot of apps do not work camera is very slow used to be very fast battery drain is crazy bad Google need to fix fastmy phone froze a few times since the update which did never happened before

  • Brett

    Why are the dock icons smaller than all of the other icons? Don't remember this being the case before 4.2. Doesn't look good now.

  • angus

    Speech to text, isn't working.

  • Toni

    on my GNex, simultaneously with the display turning on for no reason, also the speaker/ring tone volume resets from _off_ to maximum volume (which can really embarrassing in some situations if you don't realize it). There are also reoccuring issues with the internet connection that i only managed to solve so far by rebooting....

  • Paul Shorrock

    I can't open Play Store - the connection just times out.
    Also got the battery problem and screen flickering that others have experienced.
    4.2 is a really bad update, and I wish I had just left things as they were.
    (Nexus 7)

  • Kevin

    The LED on the Nexus 10 is broken too. Sometimes it works, sometimes it doesn't. There is a thread on XDA about it.

  • Phil Lyndon

    Serious issues with the lock screen. Does not respond to pressing the power button to turn on. Also when playing music, the Google Music controls don't respond. Can be a big delay (5-10 seconds) before the screen comes on/controls respond.

    I have no widgets, other than the default clock, to slow this down and had no problems on 4.1.

  • Old John from Alabama

    I updated to 4.2 within a few hours of getting my Nexus 7. My single biggest complaint is that I can't connect to it with my PC. I can't enable USB debugging because the menu option that gets you to that selection isn't there. If I can't connect, I will soon regret buying the thing.

    • Neelaksh Bhatia

      You can go to the "about phone section" and tap the build number several times to enable developer options.

  • edude03

    I'm very surprised to say that not only have I not had any issue with my Galaxy Nexus since upgrading, almost everything has gotten better.

    (Slightly) better battery life
    Much improved Ambient light sensor algorithm
    No lag anywhere (even opening Now or switching apps)
    Easier to unlock phone with the new lock screen

    There is probably something I'm forgetting but I'm shocked to hear that I have none of the issues that others are having. The only thing I can think of is I did a clean wipe since I went CM10 -> 4.1.2 -> 4.2

  • Nathalie Khodiakova

    My Nexus 7 seems to works fine after the update except for one thing. When the tablet is idle for half an hour or more and someone sends me a message in GTalk, notification arrives ONLY when i unlock the screen. Did anyone get this issue?

  • Robbie Adams

    Cellular signal since 4.2 is horrific. What a major mess this update has been

  • SMR

    I haven't experienced any of the problems on my nexus 7. Yes, android 4.2 isn't add light as the earlier version was. Ram usage is a little more than the last iteration. But performance has improved in a lot of areas, like switching between apps, minimizing, maximizing etc.

    Swype keyboard is an absolute joy to use. Also, i have noticed better screen contrast and the ghosting issue is gone(the annoying colors which i used to get immediately after watching a video). The default font is also a little darker to ensure better readability.

    Overall, happy with the update. Dunno what are you guys scribing about. :-)

  • Adam2323

    I have a Nexus 7 and I have really been hit with the slow-charging bug. I was using it tonight for about an hour while it was plugged in, and the battery reading actually dropped a percentage. Did anyone at Google even bother to test this release?

  • chris

    gallery doesnt work/lag

  • GTP20

    I hate 4.2. Going back to 4.1. My bluetooth doesn't work anymore, I can't change my alarm ring tones, my camera now sucks (pictures quality is terrible and picture width is greatly reduced), and after 3 days I'm so sick of this stupid looking clock with the ridiculous bold hour. I've been considering a Windows Phone 8 device since they were announced and after this disaster from Google it might be time.

  • http://www.facebook.com/CttCJim James Reinsch

    My nexus 7 is just plain slower! All my games are choppy, load times are up, even coming back from lock screen is lagged.

  • http://www.facebook.com/profile.php?id=502647778 Daniel Engel

    1. Battery drain here, until I manually re-added an exchange account it was draining very fast.

    2. Seems less smooth than 4.1 (project butter), even doing simple tasks like turning the screen on/off have a noticeable delay.

    3. GPS was spotty since 4.1 but now it is UNUSABLE for navigation in 4.2. Just can't seem to get a lock on my location any more.

    Here's hoping for a quick patch. (Galaxy Nexus - yakju)

    None of these bugs but I have 2 BIG BUGS:
    - Impossible to stop the screensaver and lockscreen in charging mode (if I don't want to put my screen off), option disappears from 4.1.2 to 4.2 !!!! plz Gogoles, don't remove what is good ;))) don't copy Microsoft.
    - And impossible to remove the sound of keyboard touch, even if in the option, it is unchecked !!! so sad.

    plzzz, correct all of these. It is very important fpr ùe/

    I sure am glad I read this article cause Iwas JUST about to flash back to stock Android from CM10 But after reading this article I'm gonna stick with CM10 because it is so smooth and stock android 4.2 sounds horrible.

  • Josue Mavarez

    Lock screen issues

  • Josue Mavarez

    Another problem, if you had an app disabled like Google book (which is my case) and updated your device to 4.2, after you enable it again and restart your device that app goes disable again. I disabled it because I wasn't using it but now I found a really interesting book and I can't read it.

  • Samuel Hart

    So I'm looking to get a Nexus 7 because everything I've heard touts it as a bloody fantastic device. THIS, is not good. If I should get one, is it going to come with stock 4.2 or lower? If it does, how can I downgrade?

  • DirkBelig

    For the first day after updating to 4.2 on my Nexus 7, things seemed fine, but then it started lagging badly. Clearing the cache helped a little, but ultimately I had to factory reset. Performance has been fine, but now I've had a couple of spontaneous reboots and Google Play Services is guzzling my battery. I don't use Bluetooth with this device, but I've got a Nexus 4 on order and plan to pair it with my car's Sync system.

    This is quite a nasty list of bugs and combined with the utter botch of the Nexus 4/10 launch, this isn't a very good month for Google. Don't break what's working, kids!
