Change the digitizer. It happens to me before. First i noticed the last 3 rows in my home screen are not responding then after a few days the pull down menu also died, i cannot login to skype because the touch keyboard specially the A and the texts next to it are also not functioning. I bring it to the dealer then after 3 days it was repaired.

most probably you have soft wakelocks with CPU high spikes. Backup your current configuration you have with TWRP or CWM. Then make a reset and tell us if you still have that (make 1-2 reboots to be sure that all is set-up).

I told you before, replace the digitizer before it's too late. The more you do something in your O3D the more it will be damaged. It is not related to softwares etc. because its hardware problem, i tried a lot before (root, kernel, ROMS, build.prop ...nothing happens)
