My Apple Watch 9 is acting weird - Is this a bug?

I HAVE OS 10.4 and

This happened to mine (v.9, purchased around Nov. 2023) for the 1st time last night. I just took it off, placed it in the charger, and the craziness stopped, didn’t get to sound alarm or called 911, didn’t need a reboot. Pretty nuts though

I had the exact same experience. I thought it would be difficult to explain, and that no one would believe me, even though I have video proof. The watch started by sending text messages to one of my recent contacts. Then, later, I noticed the timer running, even though I hadn’t started a timer. It went downhill from there. Screens started changing on their own. The screen wouldn’t respond to my touches, and when I tried to hold the off button, it launched into emergency mode. It called my emergency contacts and 911. I have had two separate episodes like this about 40 days apart. After the first, Apple had me delete and reload the watch as a new watch without my prior data. That didn’t fix it because it happened again. This watch needs to go. It scared my wife the second time because I was away on a road trip by myself at the time. She got an emergency call saying I needed help. This is not helpful.

My Apple Watch 9 is jumping as well - enlarging screen - and then trying to log in - clicking like keying in a password. I spoke to help and sent my watch in for repair - they received it and returned it in less than an hours advising that there's nothing wrong with it -

I updated mine in Jan 2024, and it has malfunctioned every day since. Contacted and spent 10+ hours with CS-Tech support. Restarts, resets, unpairing fixed it for a couple days, then back to where we started. Workout mode was super functional until the update. Now, it jumps to laps, segments and other function but won’t tell me distance at a glance. Finally, replaced it with a Garmin.

Had this issue just now. Didn't know how to search for a solution and "Apple Watch 9 acting crazy" pulled up this post. The force restart (crown and button press) seems to have fixed it, for now...

Mine also just done this March 29,2024 went crazy then called 911 and I couldn’t stop it then I finally got it to unpair from my phone.

Mine just started doing the crazy pressing of buttons and opening apps. A restart took care of it.

The "long" post you mentioned, above your post, is to get out of the wrong passcode loop, and if locked out the only option is to wipe.

Apple def fixed it on March 7th.

Read the last page.

my Ultra II just went nuts. 4/6/24. So it was not fixed with the last update. I’m doing a hard reboot to see if it helps.

You didn't update to OS 10.4 on March 7? What the ....?

Still on OS10.3?

Apple Watch uses a LOT of battery - Apple Community

Apple Watch basic diagnostics - Apple Community

Still on IS10.3? If so then yes the bug is definitely still there

Ive rebooted mine, updated mine, unpaired and paired mine. Still glitching.
