We're not Apple- just fellow users volunteering our time to help others.

If you don't have a computer, you'll have to remove the beta profile and wait for the next update with the steps below-

1. Go to Settings > General, and tap VPN & Device Management.
2. Tap the iOS Beta Software Profile.
3. Tap Remove Profile, then restart your device.

However, this will only allow you to revert to a previous, full-release version of iOS when another update comes out, and you'd have to wait until then to go back to iOS 15. As it seems unlikely that Apple will release another iOS15 update before iOS 16, this might not be a solution.

If you take it to an Apple Store, they'll be happy to help.
