IOS 15.0 iPhone Storage Almost Full

Hi Carder9608, 

Thank you for using the Apple Support Communities. 

It sounds like you're seeing a message that says iPhone Storage Almost Full and we're happy to help! If your iPhone has enough iPhone storage, Restart your iPhone, then check to see if the problem is still there.

If you've restarted your iPhone and you're still seeing the iPhone Storage Almost Full message, then should contact Apple Support for further assistance.

Have a nice day.

This is a known bug in iOS 15. The message should not prevent you from using your iPhone. We are hoping for a fix in a soon-to-come update of iOS.
