I have an iPhone XR (fully up-to-date on iOS 16) and an Anker Wireless Charger.
Twice now while the phone was sitting on the charging base I have seen the screen come on and begin scrolling down the phone, then other movements happen; it looks like someone is controlling the phone remotely, but is this even possible via a charging base? I am an IT Professional and so am not ignorant of this sort of thing and (to my knowledge) there is no way to control an iPhone remotely other than "Switch Control" and that is disabled (Settings > Accessibility > Switch Control).
I just noticed the Apple Watch charger is beside it; could that be the culprit here? Perhaps the wireless charging base is just malfunctioning?
