I'm fed up with this buggy update

After the OneUI 7 update, my phone is constantly trying to scan a fingerprint in my pocket (yes, the "block accidental touches" setting is on) so I have to unlock the phone with the pattern every time; this didn't happen before the update. The phone often doesn't ring when someone calls me, and I just get the notification that I have a missed call; this sucks, constantly having to call people back. It keeps calling the fire department somehow (no, it's not my emergency contact), and I can't find a way to stop this.
