Touch screen

[AD]

Hi ! There are some days when I encounter a problem. The problem is that when I touch the screen sometimes trembled screen. After this incident, i'm turn on show touch and I saw many touches shown on my screen ! Restore I've done, I've done a flash, but still the same problem.:smileycry:

Do you have any 3rd party apps that could be related to this behaviour?Any screen protector?

[AD]

You see i'll remove protector ?
