I have a galaxy s20+ and after updating to android 12, my password and biometrics security menu stopped working because it won't take my gestures. Unlocking my phone with gesture works but i can't change it. After restarting the phone everything works as it should, but after 1 day i have the same problem again (i tried restarting atleast 3 times). Moreover, this problem is not only related to settings but also to apps I log in with biometrics and for some reason it also logs me out of instagram.
Thank you for your answers.
Please try some generic troubleshooting such as https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may also need to insert your earphones and or hook up to a laptop. No need to launch anything, just turn it on and https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/
as a last resort a back up and factory reset may need to be considered.
I updated my Fold 3 to Android 12 with Samsung One Ui 4 and the Biometrics side of things have been fine.
