Galaxy S3 LTE Android 5.1 Update

Android 5.1 update is on the roll, and the latest device to receive the treatment is Samsung Galaxy S3 LTE, model no. GT-I9305 — mind the model no. please if you’re interested in this, or your could brick your android device.

Android 5.1 is the latest update, that surprisingly enough launched with Android One devices. The 5.1 update brings good bunch of nifty additions to the OS, including some of the best animations we’ve seen on mobiles screens. The tweaks to volume pop-up, plus the additions to priority mode, among other things, make 5.1 very appealing.

Samsung’s long stopped providing updates for Galaxy S3, you cannot look towards South Korea and hope an OTA to arrive on your phone. If you wanna test out the Android 5.1 update, custom ROMs are your friend. We’ve got OmniROM to share with you today, and we expect the CM12.1 to arrive soon, as it have already gifted Android 5.1 to many devices including the HTC Desire 816, Galaxy Note 3 and OnePlus One.

And btw, keep in mind that this is test build, not a daily driver by any means and thus you may encounter bugs many a times.

You need TWRP recovery for this, of course, because you cannot install a custom ROM’s .zip file without a custom recovery. Grab one from here, if you already know how to work with fastboot mode. There’s good instructions set there, too. For more help, Google is your friend.
