Sony Xperia J reportedly and surprisingly getting Android 4.1.2 Jelly Bean upgrade

Sony Xperia J

Quick, name three Sony smartphones still running Ice Cream Sandwich that you think would hugely benefit from a JB upgrade. Does anyone have the Xperia J? Probably not and yet the 4-inch mid-ranger (low-ender?) is being slapped with an Android 4.1.2 software bump as we speak.

Don’t get us wrong, we’re not complaining. After all, even the most modest members of the grand Android family need to get some attention and love once in a while. It’s just that Sony would have probably wanted to roll out JB to the Xperia S first. Or to the P. Not to mention the TX.

Oh, well, it is what it is and us bitching about it is not going to change a thing. Besides, you have to admit the prospect of seeing Jelly Bean perform on a phone with a single-core CPU and 512 MB of RAM is really, really intriguing.

What’s weird is that Sony is yet to come forward with an official announcement on J’s upgrade, meaning that it’s probably still limited to certain regions. Many J users are reporting getting JB OTA ever since last week though, so do take the time to perform a quick manual check for updates or fire up the PC Companion software.

Weighing in at around 392 MB, the thing will take some time to download and install, so make sure you have your battery above the 50% mark and an active, strong Wi-Fi connection. The new firmware version should be 11.2.A.0.21, the kernel 3.4, while Google Now, Project Butter and a series of performance enhancements and bug fixes lead the changelog.

Has anyone got the 4.1.2 bump on the J? Where, how, and, most importantly, how does the software look and feel? Is it everything you’ve dreamed it to be or is it clunky because of the low-end hardware?

    And arc/mini/live walkman/ray etc which are faster than this didn’t get 4.1?? o.O

      Nope. They are slower.

        Adreno 205 is about 5 times faster than Adreno 200
        And both of them have 512mb ram.
        Please tell me more about the J being faster…

      u forgot the dual core SOLA!

      • George

        Yup,you’re right! ;)
        Although i was refering to the single core xperias right now. :)


    maybe it needs it most.. as you all say.. j is slower than the rest gettting android jellybean.. so they must give it more speed than the rest.. just my opinion though.. and maybe.. they are still looking on how to maximize the upgrade on faster phones.. so that when they release it.. it’s as smooth and fulfilling as heaven.. just another opinion of mine though.. =D

  • Fercho

    Yeah! Roll out the J!

  • Updated jesterday, performance is nice but battery drains faster but i will give it a few days to charge and discharge a few times, they say that after doing that, battery life increases.

    I updated when the update came out and my phone became a rotting peace of sh*t
