Q: Back camera not working.

Hi

You can try following the instructions here:

• Get help with the camera on your iPhone, iPad, or iPod touch - Apple Support

However, as your iPhone was dropped and appears to have suffered damage, I suggest that you instead contact Apple Support (mail-in service may be available) or make a Genius Bar reservation to arrange for your iPhone to be inspected and to establish your available service options, timescales and cost.

• Contact - Official Apple Support

Repair service price information for iPhone is available here:
