Lock button not working

[Lacey886]

Since the recent update, I cannot use the lock button at all on my S21. I can't even turn my phone off with the button. I've been through all the settings and nothing will fix it.

Slide down the notification shade, tap on the power icon, then at the bottom, tap Side key settings.


Edit: if that doesn't help, try going back into the notification shade, then power icon, and try restart the phone.
