This phone heats very badly. I got afraid whether it is going to blast . Because of heavy gaming the performance is very good .It has 4 GB ram . Mediatek GPU, 2 GHz snapdragon Octacore processor.The battery life is very good since 2Ghz 64bit processor drains less battery. 64 GB inbuilt memory. Because the phone has 2ghz the chipset heats up soon.
