Galaxy Mega’s elder variant, the Mega 6.3 runs on Android 4.2.2 Jelly Bean. Like its younger brother, the Galaxy Mega 5.8, Galaxy Mega 6.3 didn’t happen to be too much unlucky in the software aspects. It did get software updates till Android 4.4.2 KitKat and that’s where Samsung officially ended its software support. Galaxy Mega 6.3 powers itself with a Qualcomm Snapdragon 400 CPU, which is a Dual-core 1.7 GHz Krait 300. The phone is equipped with a 1.5 GB RAM and 8 GB / 16 GB internal storage options are there.

Unfortunately, because of the hardware restrictions the Galaxy Mega 6.8 owners cannot enjoy the new stuff that Android OS has brought up. We do not mean that it’s impossible, it still is possible, but it’s only possible by means of some nice custom ROM.
