Required to enter password several times a day to unlock devices.

Hello I have an issue with 2 devices, my Galaxy Tab S9 and Galaxy S21+. Both are running on Android 15 /One Ui 7. I have face recognition and fingerprint set up to open both devices from their lockscreens, and for as long as I have owned the two devices, I have become accustomed to entering the password every 72 hours. However in the past three weeks, I am now be asked for the password on the Tab and S21+ several times a day maybe four or five times in an hour. The face recognition and fingerprint still work fine when there are on lockscreen but for the majority of the time they don't appear. I have changed the password on both devices, removed all of the biometrics and started from scratch, and I'm yet I'm still being asked for these passwords instead of biometrics to get pass the lock screen 20+ times a day.

If a phone has face unlock enabled, biometrics will disable after the phone hasn't been touched for 4 hours. It will also disable biometrics every 24 hours.

If it's asking you to do it that much, it might be detecting something as a face, realising it isn't you, then locking biometrics due to the wrong person being seen
