Screen doesn't respond to touch, have tried all your resetting tips.

Hi there,

I have been reading all answers regards to iPhone 4s touch screen problems and just would like to confirm I have done all I could before replace the screen.

I have replaced this screen 4 months ago and in the last two weeks it started showing the first signs of problems, always when typing the letter P or anything far right. Now the 3 rows on the right keyboard plus the bottom screen doesn't work at all. It is progressing to the middle of the screen.

I have tried resetting all settings plus going though iTunes and resetting again. Turned it off for a day and resetting again... nothing seems to work. Does that sound like a screen needing to replace to you?

Thanks
