True tone
I have updated my iphone 8, now supports ios 12, I can not use a real tone, it was a very used by me, and my opinion is very useful. can I solve?
It appears that if you have replaced your screen with anything other than an Apple Original Screen, once you update to iOS 12, True Tone no longer works. This has happened to others which is why I asked. If you want True Tone, you'll need to schedule an appointment at your Apple Store Genius Bar and have Apple replace the screen.
