Replaced screen, but missing some touch sensitivity
Just replaced the screen in my iPhone 4 and while testing, I noticed that there is no touch sensitivity on the top keyboard row (QWER..).
It seems like it is a straight line horizontally without touch. Otherwise everything seems to work fine.
What kind of issue would this be?
Would it be a completely screwed up screen or maybe it's just dirty there or what? Or too much pressure?
Is this a good question?
