Galaxy s4 touch screen

[andreashb]

Hi! I just replaced the whole display assembly on my Samsung Galaxy s4 (i9505), and I have som problems with my touch screen. It only works for a very short time after I click the lock/unlock button. And then it stops working. I could lock the phone and click the button again and it will work for this short amount of time once again. I have done a full factory reset, but the problem is still there... I can't understand that this could be a bad quality screen because it works a little time? Please help

I also replaced the screen and have the same problem, but in my case the recurrence is only about twice a day on average though sometimes it happens more frequently. I have decided that locking/unlocking twice a day is better than paying another $600 for a phone.
