What should I do if my Apple Watch Ultra 2 starts acting sporadically

- Flicking between different screens
- Typing its own texts
- Entering random passcode attempts
- Calling emergency services

Here are the steps to resolve the issue:

Force Restart the Watch

1. Press and hold both the side button and Digital Crown simultaneously for at least 10 seconds until the Apple logo appears[1][4][5].

2. If a forced restart doesn't work, unpair the watch from your iPhone. This will erase the watch and you can pair it again[1][2].

Reset the Watch

1. Put the Apple Watch on its charger[2].

2. Press and hold the side button until you see the power off slider. Slide it to power off[2].

3. Press and hold the Digital Crown until you see the red "Reset" button[2].

4. Tap Reset, then confirm to reset the watch[2].

5. After it unpairs completely, you can pair it again and set it up as a new watch[2].

Update to Latest watchOS

If the issue persists after resetting, update the watch to the latest watchOS version available[2][4].

Contact Apple Support

If the sporadic behavior continues, contact Apple Support. There may be a hardware issue requiring repair or replacement under warranty[5].

In summary, force restart, unpair/reset, update watchOS, and contact Apple if the Apple Watch Ultra 2 exhibits strange, uncontrollable behavior. These steps should resolve most software-related issues causing the watch to act sporadically.
