Good news, everyone! The Nexus 4 Android 4.2.2 OTA (JDQ39) is finally here, surprisingly late in the update cycle, following the Nexus 10 and older Nexus devices, such as both variants of the Nexus 7 and both variants of the Galaxy Nexus. Chances are you probably don't have the coveted update notification just yet, but who wants to wait if you can sideload it manually? Rooted, unrooted, stock or custom recovery - it matters not.
A few days ago, Google pushed out the Android 4.2.2 (build JDQ39) update to the takju variants of the Galaxy Nexus. Takju Nexuses are the devices sold in the Google Play Store, whereas yakju ones can be found in other retail channels. Good news for those waiting on the latter - though a day after its sibling, we finally have the yakju OTA file that can be applied manually on any stock device, including unrooted ones with stock recovery.
A small change in Android 4.2.2 has left one of the biggest ad-blocking app on Android basically dead in the water. Adblock Plus is one of the web's most popular ad-blocking tools, and has been available for Android since November of last year. So, why has Google effectively killed it? Security issues.
Adblock Plus relies on the internet permission in Android to function, but it relies on a rather specific subset of that permission in order to work: the ability to automatically set a device's proxy server to 'localhost.' As is pointed out on a thread in the Android issues section of Google Code, this is a pretty serious security flaw.
If you're looking for the Android 4.2.2 update for the Nexus 7 3G, good news: we've got the link to download it from Google's servers (download). To get a sense of what's new in Android 4.2.2, check out our post on the new features here. And if you want an even deeper dive into the changes, you can check out the developer changelog here.
So, how do you go about flashing the Android 4.2.2 update to your Nexus 7 3G right now, instead of waiting for it to be pushed to your device over the air?
So this is interesting, Google just updated the product page for every Nexus 7 model on the Play Store, and the change on every one is the same: estimated battery life. Previously, the Nexus 7 was listed as having "Up to 8 hours of active use," but now the figure has been revised to 10 hours - within a day's time of the release of the Android 4.2.2 update (manual update download here).
Android 4.2.2 is out, and while an OCD-fueled 4.2.2 edition of Getting To Know Android is on the way, we figured it would be a good idea to highlight the big user facing changes that came with this release. We already covered the new ADB Whitelist and posted the raw developer changelog, so this should be the last of the important stuff.
New Download Notifications
First up is the new notification for in-progress app downloads, which now shows the percentage and an estimated time remaining for your app downloads while they are happening.
Following yesterday's Android 4.2.2 OTAs to various Nexus devices, Google today followed up with the push of all 4.2.2 open source code changes to AOSP. There is a lot here to parse through this time around compared to the minor 4.2.1_r1.2 commit from 10 days ago.
We've already identified some obvious user-facing changes, which we'll post about separately soon to keep it clean and organized. The purpose of this post is, as before, to find the low-level changes that may not be obvious.
Worried about an ADB-savvy thief stealing the precious data off your stolen phone or tablet? Well, Android 4.2.2 makes doing that a little harder now, with the addition of a USB debugging whitelist feature into the OS. The way it works is pretty simple - when you connect your PC to your Android device via USB, Android gets your PC's RSA key (an identifier token). In Android 4.2.2, when you have USB debugging enabled, this now causes a prompt to appear on connection, seen below.
It's begun - the newest version of Android, 4.2.2, is being pushed to AOSP right now. We saw the accompanying Nexus OTA rollout start last night, with update files slowly springing up thereafter. Right now, 4.2.2 builds can be downloaded for the Takju Galaxy Nexus, Nexus 7 (Wi-Fi), and Nexus 10.
The build number is JDQ39 and the tag in AOSP is android-4.2.2_r1. Here are a few of the many directories that have been updated:
While the push has just started this morning, source will likely continue to show up throughout the day, and we'll update this page as that happens.
While the official OTA update to Android 4.2.2 began rolling out to the Galaxy Nexus, Nexus 4, 7, and 10 last night, you may not have received it yet. We already posted a link for the Galaxy Nexus takju build, but now we've got a couple more to share.
Update: JDQ39 from JOP40F for the Nexus 10 added.
- Nexus 7: Android 4.2.2 update (JDQ39 from JOP40D, 47.7MB) (Note: Wi-Fi model only, aka grouper/nakasi)
- Nexus 10:
Your device needs to be running the JOP40D build in order to flash the updates, doing so from another build will probably just fail, but we wouldn't attempt it either way.
