My iPhone 13 Pro Max screen turned green after iOS 17 update. What to do
3 days after iOS 17 update screen turned green which back to normal after forced restart. However, it turned permanently green again after 2 days. Forced restart not helping
Do you have Night Shift/Dark mode enabled or brightness set is too low? I'd disable it and force restart, if not working try to restore the iPhone from iTunes. Do you have Apple care + or is the iPhone still under warranty?
I'd anyway and regardless of the attempts to fix it, contact Apple support and have the iPhone checked or replaced.
