Meta quest 3s controller
Yesterday I was playing with my controller just fine not turning off on me but today when I move my arm to fast or just move then the wrong way they disconnect and its only been happening to the left...
Sounds like the batteries are a little loose. Did you use a different brand this time around, perhaps? Try adding a bit of aluminium foil between the contacts to prevent accidental disconnects when you are flailing your arms about. Maybe clean the contacts with a cotton swab and a little white vinegar.
