Problem with touchscreen

[isknfs]

I have some problem with touchsreen. All work fine until I put my device in pocket (or press him). After I take out my device I can't unlock him, and me need turn off screen and turn on him several times, until touchsreen stabilized.
Who have simmilar problem with touchscreen?

same here. I can click few times right after I turn on the screen but only for one second.

same here... tried reflashing etc. via *#7353# -> dot mode, I can see that a spot is being "pressed" in the middle of the display and 1,5cm down from the top. And constantly, thus another touch is not possible. Usually after locking the phone and turning the display on again it works for some time. But even in the recovery it doenst work... sometimes... under key test. Randomly the touchscreen is being pressed.
Had no problems until now... always had a screen protector foil on, but even with a new one and without one it doenst work. Did not dropped my phone, neither I have screen cracks etc...
Any suggestions?
