A72 randomly makes 2 beeps and shows PIN entry screen to unlock the phone

[IanT65]

My A72 is randomly making 2 slightly different beeps (beep bip is the only way I can think to describe it) while locked & not in use. When I open the cover it is showing the unlock screen to enter my PIN.

Since I haven't touched the phone at all I'm wondering what this means. I certainly haven't touched the buttons to unlock the phone so it's a little worrying that something appears to be causing it to show the PIN input screen.

Can anyone enlighten me please?

Hi! Welcome to the samsung members!

May sound a little odd- try turning off NFC and see if it occures again

[IanT65]

Thanks johnz237,

I'll attempt that soon when I'm not going to be using NFC for a while. It's only happening every week or fortnight which makes it a little difficult as I use NFC for payments etc.

Hi @IanT65 and warm welcome to the community 👋

Turning off NFC and turning on when needed should help.

Here's some people with similar issues, turning NFC seemed to helped:

Thanks for the links @lminvti but they are when the poster is unlocking their phone which isn't the case here, I'll read them though.

Why didn't I think of turning it on only when needed? Great idea.

Are you using any magsafe? Cards kept nearly? Galaxy watch? These can trigger noises via thr nfc chip

[IanT65]

None of those, nothing that would be NFC related, the phone is on my desk and the only thing anywhere near to it is my monitor, printer & a speaker.

[johnz237]

Hm. Maybe try turning on accidental touch in settings?

[IanT65]

That's already on and nothing is touching or moving the phone.
