Once I changed the battery in the iPhone 5s and at the same time decided to remove dust on the camera, for this I had to unscrew the protective plate, disconnect the display and camera cables.

Once I dropped a new iPhone 5s from a knee-height onto a tile, the phone was in a protective bumper, as soon as I lifted it, I noticed that the flashlight button was not active. I rebooted it, the button became active and the flashlight worked, at that moment I even shot a video, but the next day when the camera was turned on, a black screen was displayed when the camera was turned on.
For some time, I managed to switch to the front camera, but the rear one did not work.
Sometimes you could see the warning “Flash is Disabled – The iPhone needs to cool down before you can use the flash.”, But the phone was not used before and naturally could not overheat.
