Any iphone aficionados out there? [View all]

My iphone 12 pro, all of a sudden, from out of the blue, stopped accepting pics or vids and FaceTime doesn't work. I can't send pics or vids either.

Yes, I turned the phone off and back on. Nothing. Everything that should be on, is on, and my internet connection has not changed...I'm on it right now. After the pic fails to send, it sends me a message with a red exclamation point next to the image indicatiing it could not be sent. If I click on that red icon, I *CAN* send the pic via text message. Vids or FaceTime? No dice.

This is very frustrating and I wonder if anyone could help, or whether there's a relatively easy fix?
