Part of the screen unresponsive with every screen
I received an iPhone 5s with the problem that a part of the screen is unresponsive. When typing you can't use the b,g,u letters aswell as in other applications these area's are unresponsive too.
I thought it would be the lcd so I tried to change the lcd. Still the same. A friend told me it could be the backhousing of the iPhone since it was in a bad state and really adding pressure to the screen. But this isn't the problem either.
Does anyone of you have an idea how I can solve this.
Tnx in advance
Is this a good question?
