iPhone 15 Pro front camera purple tint with center line

That's likely a hardware issue and should be checked at your Apple Store Genius Bar --> Genius Bar Reservation and Apple Support Options - Apple

First, try ➢ this helpful guide for a possible solution.

If that doesn’t help, then Force your iPhone to restart:

1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button until you see the Apple logo (this might take longer than 10 seconds).

If that didn’t help, then I recommend service.

Service Checklist:

• iPhone service pricing.
• Check AppleCare Coverage.
• Get your iPhone ready for service.
