Samsung’s Galaxy S II is definitely one of the best Android devices available around still today. Samsung pushed Android 2.3 Gingerbread in the device and brought it to the Android 4.1.2 Jelly Bean through OTA updates. The device stopped receiving further Android updates, Samsung has been pretty good with a device that’s way too old now. Perhaps this didn’t effect the device’s charm as the development forums are full of Galaxy S II’s custom ROMs. So, just in case you’re looking for a higher Android version to install on your device, custom ROM may be the best choice.
