Front and rear camera black, flashlight not working - probably software error
Hi,
I bought a secondhand iPhone 7. I did a factory reset and everything worked fine for a couple of days.
I went to France (from Belgium) in a car without airco (12h drive) while it was very hot. I never put him on the dashboard and didn't get the overheating message. But suddenly the camera didn't work anymore, all I got is a black screen. Not sure if the drive and heat are related to the problem.
I restarted the phone a few times, without succes. After a while, I restarted by holding the volume-down button and the power button, and suddenly the camera's where back.
Not long after that, they went out again. Now I didn't do a reset, but a full wipe and reinstall. After 4 times, the camera was back. But the morning after that, it was broke again.
Before taking it to an Apple Repair Center, can I try some things to fix this myself?
iPhone 7, iOS 13
