Chosen Solution

At first the camera app would just shut down, so of course I restarted the phone. Then the camera app was working but it was fixed in selfie mode. I was not able to use the rear camera or the flash light. The rest of the phone is working just fine but I can’t access the rear camera of the phone in apps either. When I press the four circle icon the the camera app, it allows me to choose between the selfie cam (This one is selected) and adding a camera. When I choose to add a camera I get the option to add photo booth. I already tried to restore the default camera setting but it didn’t help.

Sir I have a same prblm flash and rear camera nt working how can get back my camera help me

It is a hardware issue with the camera itself. Its a very easy repair to do. Order a replacement camera and you should be able to swap it in a matter of minutes. Because iFixit rocks, there is already a very detailed thread on this: How to Replace Rear Camera Module?
