Sony xperia E3 dual is very hanging and overheating problem and we have two time software updated but phone is very my experience about itroot it with noob friendly guide explained on xda and after that install folder mount and njoy heavy games.
belive me guys this phone can play any game without any lags due to low resolution. thus adreno 305 handles flawlessly.Worst phone ever. Memory problem, lots of bugs which will never be solved by Sony. Choose any other brand. I am buying Samsung on 5 which is cheaper than this crap and gives good performance
