Xperia Tablet Z WiFi owners, the time has come for you to make the jump to Android 4.2.2. The latest firmware update, version 10.3.1.C.0.136, updates the six-month tablet to the next version of Jelly Bean and brings with it a slew of features worth salivating over, such as support for 64GB SD cards, and some that may be more subjective, such as the transition from a tablet UI to a phone UI. This means that the soft buttons (back, home, and recent) are now centered at the bottom of the screen, and the notification bar has been shifted to the top. Like the update that previously rolled out to the LTE version of the tablet, some elements of the UI still differ from that found on Nexus devices.

Xperia3 Xperia2 Xperia1

Here's the change log straight from Sony.

What's new:

  • Latest version of Sony Media Apps with seamless integrated services
  • The my Xperia application that helps you find your phone and secure everything you have on it. Read more at myxperia.sonymobile.com
  • New customisable navigation bar with quick settings
  • New widget functionalities, both on lockscreen and homescreen
  • Support for bigger (64GB) SD card so that you can store even more on your Xperia™ tablet Z.
  • Multi-User function support

If you are the proud owner of an Xperia Tablet Z, you can get the update wirelessly or by plugging your tablet into a computer. And when you head over to Sony's support page, ignore the notice saying the latest available software is Android 4.0. This update will not downgrade your device.

    If you're a Music Unlimited user (or if you want to try it out), this update is really cool. Music Unlimited is now fully integrated in Walkman, which makes it look, sound and work great!

    can anyone see if the bluetooth & wifi at the same time bug has been fixed with this update? me and dozens of others in various message boards all have the same issue that when something is connected via bluetooth, wifi speeds drop to under half a meg/second (practically unusable). would be so happy if this fixes it.

    • dro

      same here.. sony please fix this!
      .. some say change wifi router freq to 5ghz..

  • Anthony O’Connor

    Cool but the current firmware 4.1.2 already supports 64GB cards. I have one in my XZ Tablet right now.

    Hey Sony, can I get a little love on my original tablet S...DAM Honey comb :(

    • Ambroos

      You should be able to update the Tablet S to ICS from the Settings menu... Where did you buy it?

  • http://cashd00d.co.cc/ WHAT?

    I wish they would bring 4.2 to the Xperia Tablet S. I want multi-user capabilities.

  • Nigel

    Is there a way to downgrade back. I want my dock buttons back in the corner and notifications and battery back down on the bottom. The new positions suck for me.

    • John

      I am calling sony every day to complain. Having the back button out of reach of my left hand is insane. I now have to remove my hand from the tablet to go back. Stupidddddddd for a tablet. The phone UI is for PHONES

      • Vadym

        Hi John! I'm age with you! android 4.2 sucks! If you will find a way to downgrade or just make b ui like it was in 4.1 wire here please!

      • Jonathan Funcke

        I'm also on the verge of phoning because they completely ignore emails.

    • Rich

      Just updated mine this morning and kinda wish I hadn't for this exact reason. Having the buttons move is a massive pain.

  • Bontot Aku

    I definitely wont upgrade to this. Love the current 4.1.2 tablet UI.

  • Vadym

    If you reading this before update don't do it! 4.1 is much better. Now it' s just a big phone with back and home buttons in center of the screen. Google, I don't think that there is a person with such a big fingers! Of you know how to change out back please write it here!

    • paul

      Downgrade to 4.1.2 using flashtool

  • rick

    yeah, wish I hadn't upgraded, not only for the reasons already mentioned by others, after the "upgrade" I can't free more than 44% ram, before I could get 79. All my apps are the same.

  • Ivo

    I have the same problem with the soft button keys It is really annoying that after the upgrade they are centered. Now it looks like every average Android phone. If you have any solution please HELP. Thanks

  • Sean Hollingworth

    What the hell is everyone whinging about?
    "Can I downgrade?"
    "Don't do it!"
    "I'm complaining to Sony"
    Blah, blah, blah!
    I'd suggest a dose of 'man-camp' for the lot of you!
    The 4.2.2 update is great for phones and tablets alike, albeit late coming!
    The pros far outweigh any cons. My only gripe would be that the update shoulda come sooner. Bit disappointed Sony took so bloody long rolling it out but now it's here, everything's good.
    Make the most of it... it'll probably be another 12 month's before we get Kit Kat, if at all!

    • JBS

      I just got an android tablet with 4.2.2. But I can't find a manual for it. Any help on this?? Where can I find a link to download the manual?

      Thanks much.

    • paul

      You are an idiot. The "new" ui is horrible, useless, not user friendly, wasting a lot of space! I will never upgrade!!!

  • Horváth Gergely

    Yaaay! Now my tablet feels like a 10 inch phone! My favourite feature right after the shitty button placement and the top notification thingy is that when you turn auto screen rotation off it sets your device to vertical mode.

    No! Seriously! Where should I complain to sony about this? As weird as it sounds I want my old version back :/

  • Beau

    Really annoyed... I want my old layout back!!! Love the multi user thou...

  • John

    Yes there is a way to downgrade. Download FlashTool (flashtool.net) and download the SGP311_US_10.1.C.0.370_Xperia_Tablet_Z.ftf (or 312 if you're 32gb) Firmware. Go to XDA and folow the instructions there.
