How to fix the pink screen bug.

• Some users have seen relief by simply restarting their iPhones (but may only help temporarily)

• • Also be sure you’re backing up your iPhone regularly

• Next, make sure you’re running the latest version of iOS (Settings app > General > Software Update)

• • And keep an eye out for iOS 15.3 which should become available soon

• Now head to the App Store and install any available updates for individual apps (App Store > tap profile picture – top right corner – > swipe down > choose Update All)
  • Another option is to delete any apps that you notice the pink screen showing up during use

• A more time-intesive approach, but you can wipe your iPhone and restore it from a backup

• If you’re still seeing the pink iPhone 13 screen bug, reach out to Apple support – while there’s no guarantee, some users with the issue have reported getting their iPhones replaced.

• Interestingly, the iOS 15.3 release candidate doesn’t include any mention of a fix for the pink screen flaw. However, it’s possible the public release could include a specific fix for the issue. Apple may launch that update as soon as this week.

Sorry but iOS 15.3 has been and gone.

Try to plagiarize more modern advice from Google next time.

This is not a bug it is a faulty phone.
