Why does my screen turn Pink when i click force reset

Hi JohnALM,

Thank you for using Apple Support Communities. 

We see from your post that you have a question about a pink screen displaying when force restarting your iPhone. We want to help. While we are unable to determine why you would see a quick flash of pink screen when you force restart your iPhone, we can address the reason why you may have had to do that. You can look at the steps in this article that talks about If your iPhone won't turn on or is frozen.

Also, it's a good idea to update your iPhone. It is always a good idea to have a backup of your iPhone before updating.

Forcing it to reset routinely is a bad thing to do; it can result in storage corruption or data loss (or both). And, as it shuts down iOS RIGHT NOW anything can happen in the process. Here is the right way to restart your phone→Restart your iPhone - Apple Support
