i brought sony z3 dual last month

since i brought i noticed that when typing there is problem with screen touch system ,as there is specific letters not typing correctly 

first i thought its from screen sticker came with the phone ,, so i used with it ,, but after 2 weeks i remove the screen sticker ,and installed new one which came with the phone , but the problem with typing still there

i did screen touch test  i found that there is longitudinal area not responding to the tough test correctly
