Samsung Galaxy Premier comes with 4.65-inch HD display, 1.5GHz dual-core processor, 8-megapixel main camera and a 1.9-megapixel front facing unit, 8 or 16GB of internal storage and a microSD card slot. At the time of its release, the Galaxy Premier ran on Android 4.1.

Since Android 4.1, many updates have been released. And Galaxy Premier has missed out on those due to it not being a flagship device. However the CM team makes sure that most of the devices can be updated to the latest Android version using their ROMs. The Galaxy Premier can be updated to Android 5.1 using the CM 12.1 custom ROM. Follow the guide below.
