Sony Xperia J gets the Android 4.1.2 Jelly Bean OTA Update

The Sony Xperia J devices started to get the Jelly Bean OTA update notification today and now its users can enjoy the latest Android features and function. Only the devices that are 100% stock got the updates, which means that in case you’re on custom ROM then you will have to revert the OS back to stock firmware.

The OTA Update to Android 4.1.2 Jelly Bean might be considered a surprise as the Xperia J packs a single-core 1 GHz CPU and 512MB RAM. It seems like the devices runs pretty smooth and if you’re one that wants to always run the latest Android versions, then this update should be the one that you need to apply on your smartphone. Note that you have to be on a full stock Android ROM for the official notification from Sony to be sent for your smartphone.

Xperia J from Sony is the 3rd device from the Xperia series that got the Jelly Bean 4.1.2 OTA Update. Xperia T/ TL and Xperia V are the other devices that got the updates. All the other Xperia smartphones should get the update until the end of this month. The firmware has also been updated to the 11.2.A.0.21 version along with the kernel which has reached the 3.4 number. This should be the last build released for the Sony Xperia J as there won’t be released any other devices.

The new updated OS will bring the Google Now, Project Butter UI and all the other Jelly Bean based functions and features that should improve the overall look of your UI. The battery life of your device won’t improve after the update and you might experience even a worse autonomy of the battery. After you update the smartphone, tell us in comments how is the new Android 4.1.2 Jelly Bean running on your Xperia J ? Also, tell us in case you find any errors or bugs while running with this new OS.

    battery life has taken a beating. my phone discharges in less than 48 hrs, which otherwise was more than 36 hrs before the update. The call history got truncated to last two days and continues to erase history beyond two days.

  • nanana

    Since Ive updated the phone to 4.1.2, i couldnt connect to the mobile network. Ive turned it on, but i couldnt use the internet. Is it the phone problem? And whenever i play the music, it will get stuck at certain times. Does anyone here facing the same problems?
