It is best qmobile phone! I am still using it. It has all features that we need!
It has tons of custom roms including cyanogen, pac, carbon, aosp, android L etc. Just search for Micromax a120 canvas 2 colors mobile in xda-developers.com and you will find all roms that can be installed in this device. Micromax a120 canvas 2 colors, Wiko Rainbow and Agua Rio are replica of this mobile and you can install there roms in this phone :D
Thanks Qmobile for making a mobile like this. I have decided not to sell or break this phone until it dies xD
