Front facing camera not working
Suddenly my iPhone Xs camera will only take selfies with the Camera App and in iMessage. I can take selfies and photos in FB messenger, FB, Instagram and WhatsApp. I took the phone to Apple store and we did diagnostics - nothing found - and forced restart, and settings reset - problem was fixed for one or two photos, and then back again. The phone is brand new - just got in May 2019. Help!
iPhone XS, 12
