Screen will not wake after replacement.
I have just replaced the screen on a friends iphone xs. I removed battery first and followed the guide to the letter. When i first turn on the phone the screen comes on, i put in passcode and can use apps, surf the net everything. As soon as i lock the screen or it locks itself, then it will not turn back on. The phone still works as i can feel it vibrate and can soft reset it. After soft reset, the screen works again, until locked. Anyone else had this problem?
