Antwoord op "Why does my iPhone 7 Plus rear camera show black screen?"Just replace the rear camera unit with a new one.... I suggest to replace with the original one. I found the original one on eBay for 55$. Even I dropped my phone and all the above things happened to me. The point is there are 2 rear cameras on iPhone 7 Plus so one stopped working and the other works on Facebook messenger and other apps. But replacing the whole unit works again.
Antwoord op "iPhone 7 Plus rear camera not working after I dropped it"Just replace the complete rear camera unit. It will work again. It happened to me as well. I dropped my phone and damaged the rear camera internally. So after replacing with original it started working again
