Z5 fingerprint sensor

Hi yesterday I've become happy owner of Xperia Z5. I have question about fingerprint scanner, I don't know if it's a common issue but it seams that scanner is easy to crack. It takes 3-5 false attempts to unlock device by other finger than the one was set up and device will unlock. I asked several of my friends and it seams everyone can unlock my phone. All you have to do is tap the scanner few time and it will unlock with no problem.I thought the FS is more accurate and won't let anyone else unlock your device. Have someone actually noticed that?

No, not actually. I have tested on a Z5 and Z5c but no one else can do that. Are you sure those guys haven't set up a fingerprint in your device?

Obviously not, I've set up only one finger, just give it a go try to tap the scanner few times with other finger when the screen is on. I wonder if the same thing will happen.

It doesn't unlock and it is strange as it shouldn't work with other people's fingerprints.

What happened was I have set up my LG watch r as trusted device, and when the watch is near my phone if fingerprint scanner will not recognise your finger after few attempts device will unlock. I have turned off that in settings and now fs works like charm.

You have to be careful with every aspect, smart unlock overrides fingerprint unlock I think.
