Touch Problm
I touch some part of the screen, it does not respond. This problem happens in Chat much significant when I touch the alphabet on the right side of the screen. or And even when I try to touch N, H and U the screen does not respond !
I figured out that there is a Verticle line in the middle of my screen which does not respond (the Verticle line starts from the Top to Bottom of screen)
What should I do to fix it ?
