Can someone screen mirror my iPhone without me knowing?

Hey, I’m asking because I sometimes see the phone lag or act weird, and I have a coworker who’s always around. I’ve checked my screen time settings and don’t see anything obvious, but is there a way to tell if my iPhone is actively being mirrored to another device without my permission?

There’s no easy way to tell if your iPhone is being mirrored covertly. Generally, screen mirroring requires your approval, but if it’s happening without your consent, it’s unlikely due to mirroring and more likely to be issue with malware or device compromise.
