Two of my customers brought back the new iPhone 6S he just bought 2 days ago and complained why the camera flash is not working. We finally found some solutions.
What to do if iPhone 6S camera flash does not work properly?
- Seriously, people tend to protect their new iPhone by using some kind of abnormal cases. Check and make sure the case does not cover the Flash.
Do DFU Restore:
1. Get DFU status
You need to get your iOS device to DFU status by holding the 2 buttons (Power and Home) in 10 seconds roughly. And then free the Power button and keep holding Home button until iTunes get connected to your iPhone.
3. Select setup as a new phone.
If the problem still remains the same after above steps, bring your iPhone to nearest Apple store for further assistances.
