iPhone Stuck on Allow this Device to Access Photos and Videos in iOS 14.7/15

Thanks for visiting the Apple Support Communities, alqahtani2022,

It sounds like your iPhone may be unresponsive. If so, the steps in the Apple Support article you found your way to the communities from, If your iPhone won't turn on or is frozen - Apple Support, provides the appropriate steps to take in that scenario. If you have not already, please try force restarting your iPhone following the guidance in this article, then move onto the "If your iPhone turns on but gets stuck during start up" section.

Even though the title of that section may not directly address your specific issue, the steps it takes you through are for reinstalling the iOS software on your phone. This particular step often can resolve an issue where the device is unresponsive.

If you have already completed those steps and cannot regain access to your iPhone, or the issue is something other than an unresponsive device, please reach out to Apple Support directly. They will have access to the necessary tools and resources to further assist. You can do that here: Get Support.

Cheers!
