Happen the same to me few months ago. One day it stops and another day it was working again and so on. I did not flash different roms, after 2 years I can expect that, I just replaced the digitizer touch screen and with the same rom it working back flawlessly. Now I don't have problems at all so it's hardware problem and you should do the same. It cost just 20 bucks.
IF I HELPED DO NOT SAY THANKS, CLICK IT.
