As you may or may not know, the front flash is not actually a flash. It is a bright white front screen that reflects light off of your subject (you). If the screen gets white and bright for a fraction of a second then the "Front Flash" is working.
IF the above is NOT happening then-
Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:
- Press and quickly release Volume UP button
- Press and quickly release Volume DOWN button
- Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).
