Small dark spots appear on the frame of 13 pro by itself, please help

Hello feyruz68,

Thanks for using the Apple Support Communities!

If you're seeing spots on the edge of your iPhone, you may want to try cleaning it to see if that removes them. This can help with how to safely clean your device: Cleaning your iPhone - Apple Support

If the spots don't seem to come off with cleaning, you'll want to reach out to Apple Support to look in to any other available options.

You can reach out to them here: Get Support

Take care!
