We have an old iPhone 7 Plus, and it has been used by 2 of the members in my family, and now they have upgraded to 13's and 14's with this phone being mine.
Despite the fact that iOS 15.7 is the latest you can install, one should have no complaint with even this old iPhone. But the problem with mine is that, I don't know how or when, maybe it got dropped or something, and now it's cameras are having problems.
The rear facing camera shutters heavily, the picture shakes, and the camera produces audible rattling notices (I might link an photos/audio/video if required). The front camera is produces pictures pitch black, with only bright light sources (light bulbs) visible, rest dark. NOTE that even after this, the interesting thing is that the Phone has no problems in recording slo-mo video from the rear camera (AFAIK slo-mo is in rear only), and it works perfectly.
If the cameras were really damaged, why would slo-mo work?
UPDATE: The front camera was not damaged, though it was almost covered with a damaged screen protector/film. I removed it, and front camera picture was clear. But the back camera is still shaking
