Fingerprint

[Anonymous User]

My girlfriend was able to unlock my phone using her fingerprint even though it's only mine registered. Has anybody else had this issue?

That's very strange indeed, @Anonymous User. Is this something that you have been able to replicate, or did it happen one time?

I'd recommend checking this in the first instance, and also checking which fingerprints have been registered as well. You can then remove any fingerprints that may have been registered inadvertently, or remove all fingerprints and set them up again:

Please let me know how you get on.

Only managed to do this once so far but my biometrics are the only ones registered to the phone.

It's not something I've seen reported elsewhere, so I want to help you figure this out, @Anonymous User. Do you happen to have Smart Lock enabled on your phone (just to see if this had some bearing)?:

Additionally, what were the circumstances where your girlfriend managed to unlock your phone (e.g. were you using a particular app, was the display off, etc.)?

Do you use a screen protector?

Thank you. It seems strange and by the looks of it, it was a one off. She was watching a youtube video tutorial that was paused and the screen went off and locked but as she pressed the fingerprint sign the phone unlocked. Also Smart lock is not enabled

I see the more romantic side of this technical issue..

Two people.. But one heart ♥ one mind ♥️.. One body..
How about that 😀

This is certainly a conundrum and one which has never happened on my Samsung phone's. 

Even when getting my partner and adult children seeing if they could.

It does sound like a one off but even that one off shouldn't have happened  !

Yeah it's never happened on any of my previous samsung phones either.

No screen protector
