Hi guys I just wanna start by saying I’ve replaced the didigitizer in this phone 2 times and the first time it went well but it broke again I replaced it and now the top left the screen is faded a transparent black like it’s super faded I don’t mind but for other people is annoying as &&^&
Sounds like you’ve just got a bad display assembly. Meaning it’s already been damaged. Or you damaged it yourself, while doing the install again. You need a fresh display assembly. iPhone 6 Plus LCD and Digitizer
I’m a technician myself and I’ve seen this happen as well maybe about 3 times…No matter how many screen you replace on the board you’ll get the same result…at this point you can only pray the persons device is still covered under warranty….Apple has a flaw with each and everyone of their devices…
