A couple of days ago, S23 started to vibrate and play sound when I unlock

I'm not sure if an update was associated with this, but a couple of days ago my S23 started to vibrate and play a sound when I unlock it. Putting the phone on vibrate, kills the sound, but even if I put it on silent it still vibrates. Here's a soundcloud link to the sound that plays. It sounds like something disconnecting.

I checked all sound options and tried disabling sound and vibration for all system activities, and none of them stop this behavior. I can only reduce the vibration intensity.

Any idea what's going on?

Try this. Go to Settings > Sounds and vibration. Toggle off "Screen lock/unlock"

Thank you, I did try it but unfortunately it has no effect.

I'll also add that I now notice it makes the sound if I leave the screen on for a while.

Solved! Somehow I must have tapped the NFC button in the quick access dropdown, and it was trying to read the credit cards in my case. Turning NFC off solved it.
