Why is my screen showing black lines after replacing the battery?
Did I break my screen? After replacing my battery it looks like this, fickering black horizontal lines across the screen.
The phone still works but It doesn’t look good. I followed the guide perfectly and was extra careful with the connectors, I tried cleaning with contact cleaner the connectors and the ports but no success.
Anything else I can try before having to buy a new screen?
Is this a good question?
