Screen burn/ghost images on dark backgrounds.
Hi all, I've had a panicked message this morning from a customer. She had purchased a used iPhone 13 and has noticed that she can see "someone else's apps behind her screen". She forwarded a video but it's hard to make out.
When the screen is dark (not off) she can see faint app icons "behind her apps". I'm thinking screen burn but she is concerned that there is some sort of virus or malware.
Unsure of device age and previous usage as I haven't seen the phone yet.
Any advice would be greatly appreciated
