Iphone 6 plus camera won't work

The first thing to try is a reboot of your phone. Hold the Sleep and Home buttons at the same time until the Apple logo appears - then release both buttons. Allow the phone to restart and try the camera again. No data is lost doing this.

Potential solutions:

• Try going to Settings > General > Reset > Reset All Settings and see if that makes a difference. You will need to set up some bits and pieces again after, but it won’t delete any files or photos.
• Some owners found it was caused by an old backup. If you are restoring from a backup you made with an older iPhone, that could be the problem. Try setting the iPhone 6 up as new, factory reset it, and then put everything on it manually, and you might find that the problem is gone.
• If it persists, then you may have a hardware fault and you should contact Apple or head into an Apple Store to get it looked at. They should replace it for free if there’s a problem.
