Screen problems after replacing with NON original
(I have repaired several iPhones parts in my life)
After replacing one iPhone 5s screen the first time it all seemed to work well instead after 1 day circa the user reported it had problems (screen responds bad at the touch, clicks itself or doesn't recognise where it was clicked).
For this reason I have put the original screen back and it was working flawlessly.
However I changed it again a second time with a different screen and the iPhone had the same problems after about a day. So I did it the third time with another one , same thing. The fourth time it seemed to work correctly, but after about a month the screen has problems again :(.
I want to mark out that putting the original screen back makes it work flawlessly.
So is it that aftermarket screens are causing the problem or could it be something else?
I always do the same procedure.
''PS: I have read a question where it says it might be the LCD shield plate (where the black soft material is on the right side) having a scratch (which it does in my case if I remember correctly), may this be the reason? Could I fix it by using isolating tape?
Thanks everyone for your advices.
Is this a good question?
