The owners of Samsung Galaxy Ace 2 were waiting for the Android 4.1.2 Jelly Bean update for a long time, and the long wait finally ends now.

Samsung has started rolling out the Android 4.1.2 Jelly Bean update for its Ace 2 models, but you might not be able to update your device right now, as the update is being rolled out in phases.

Here are the details of the official firmware for Samsung Galaxy Ace 2:

Android Version: 4.1.2 - Build JZO54K

The smartphone was released running Android 2.3 Gingerbread out of the box. However, the smartphone did not see any update between the Gingerbread and the Jelly Bean and missed out on the Android 4.0 Ice Cream Sandwich completely.

Users of Samsung Galaxy Ace 2 will not be disappointed with missing the Ice Cream Sandwich update as their devices are going to enjoy a number of great features with the Android 4.1.2 Jelly Bean update.

The Jelly Bean update will bring some amazing features to the device as well as enhancing the performance of the hardware.

The Jelly Bean makes the Galaxy Ace 2 power efficient and makes the phone's performance better.

The user interface (UI) of the device really gets better with the update and navigating the device gets faster and more fluid, so moving between home screens and switching between apps is effortless.

A swipe from the camera viewfi­nder lets the user quickly review the photos taken without having to leave the camera app. Android 4.1.2 also customizes the home screen. Widgets can be placed on the screen with ease and everything else automatically moves to make room.

The Android 4.1.2 Jelly Bean update also comes with Google Now, which lets you know the temperature of your city, traffic conditions, live scores and many more things in just one application.

The Android 4.1.2 Jelly Bean update for Samsung Galaxy Ace 2 device will be available over the air (OTA) and via the Samsung Kies.

Owners of the unlocked devices are expected to get the update very soon, but if you are under a contract then you will have to wait for your carrier to release the official firmware.
