Why is the back camera on my iPhone not working?
There are a few reasons why the back camera on an iPhone might not be working. One possibility is that the lens has become dirty and needs to be cleaned. Another possibility is that there is a problem with the camera itself. If the back camera does not work at all, it may be because there is damage to the circuit board or the lens. In any case, it is best to bring the phone in for repairs or replacement.
