Everyone's fingerprints unlock iPhone SE!

[AGoldenSky]

My son's just noticed that everyone's fingerprints can unlock his phone (iPhone SE 2020 - iOS 15.6). I've deleted the existing fingerprints, reset the phone and just added the print from my right thumb yet I can use all of my fingers, my son's and my wife's to unlock the phone.

I'm either missing a really basic setting or there's something weird going on - any ideas...?

you created a passcode first? Here is Apple’s guide on how to setup Touch ID.

Do you use a screen protector/skin on top of the sensor?

Yes, I created an alphanumeric passcode before the fingerprint.

No, nothing on the home button.

It sounds like the sensor is defective. I’ve heard of this happening if there was something over the sensor but if that’s not the case it’s probably defective. It would make a neat party trick but perhaps you want to use a passcode instead

OK thanks. I've emailed the retailer this morning as it's still less than a year old.
