How to Update Galaxy Ace 3 GT-S7272 to Android 4.2.2 XXUANA1

Galaxy Ace 3 GT-S7272 can feature Android 4.2.2 as soon as you want it to. It’s all in the update procedure you’ll read about today.

The firmware used in our update is XXUANA1. It came out for the first time earlier this month for the following two countries: Russia and Ukraine (Kyivstar). This new official firmware comes packed with the Android 4.2.2 Jelly Bean and its great features. They’re as follows: a much better Bluetooth audio streaming and a new Gallery app.

You will have a new set of sounds for wireless charging and a USB debug white-list. When that’s not enough, you also get low battery bug fixes and the possibility of long-pressing the WiFi Bluetooth icons in Quick Settings in order to be able to toggle the on/off state. A new set of download notifications is also available, as are many customization options.


An already rooted Galaxy Ace 3 GT-S7272 is going to suffer from the update. Here is how: its root access will be revoked and the system partition will be erased. But these cons will be forgotten once you find out that your device’s internal and external SD cards will not be affected. The important data on your handset will also be saved from damage.

Since the new firmware has an activated KIES logo, you can very easily upgrade your phone with Samsung’s KIES. That is, if there’s stock ROM running on the handset.

If you’re done with the pre-requisites and you’ve made sure you use the Galaxy Ace 3, go ahead and update the latter with the steps below.Galaxy-Ace-3-GT-S7272
