There is a part of my phone that doesn't press

[AC Question]

I've tried the app called screen touch test and I found a small bar in the screen... it annoys me greatly that I can't press the "P" button properly (Or I can't I have to turn it landscape just to press the "P" button.) I have tried using other keyboard apps but I still won't work... When I press the "P" button it presses the "O" button when I'm in portrait... Please help me....
