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

OS 10.4 still has this bug.

Happened to me just now with my Ultra Series 2. Went insane with random presses. Hard reboot fixed it.

Correct but the time may vary, the important thing is to wait for the white Apple logo to appear, then let go.

I also did the reboot as suggested by Apple - it fixed it for about a day - when I sent it in for repair it was working fine - also bought in December 2023.

My watch was going bananas, I couldn’t put in my passcode, or turn it off, so I stuck it on to charge, it seems to have worked 🤞🏻

My watch sorted itself out after two things occurred. I put the watch on the charger and while it was there I checked and my phone had an update available so I did that one. Watch charged up and acted normally. I checked for watch update and watchOS 10.1.1 said preparing. It has now been at least 12 hours and the update still says preparing. Just to double check I verified charge greater than 50% and put watch back on charger to see if the update would proceed. It did not.

Mine just started doing this! Trying a force restart because it wouldn’t let me turn it off. Screen is jumping all over the place and the watch is not responding at all. Just bought it in November. Had my previous own for years with ZERO issues so I’m not pleased.

I have the same problem. My Apple Watch Ultra II suddenly went nuts. It started with many message on my iPhone for keyboard input, like when you type your password on Apple TV. Then it was like somebody took over my Watch screen. I saw constant random input of text. After a while the watch got time locked, because of the wrong unlock code. Now I have to wait for 3 hours! before next attempt to unlock. I put the Watch on the charger for now and hope the error is over by next morning.

Happened to me last night, freaked me out! Oddly same exact thing happened with my iPhone too, at the same time, it was crazy! Phone was easier to turn off. Apple needs to answer to this, what’s going on?!

This also happened to my series 9 last night at 5am. Started playing my Spotify music in the middle of the night on my phone, and then when I tried to turn it off, it hit the SOS and called all of my emergency contacts and the police. Almost gave me a heart attack instead of saving me from one.

Video of it happening

You’ve just described word for what what my watch just did in Lidl !!! I was so embarrassed the emergency sos alarm was sounding it text my Mum and called 999!! I apologised profusely to the lady and had to convince her I wasn’t being murdered or assaulted. I couldn’t turn it off and it kept entering numbers on the pin code

After the 3 hours were you able to put your passcode in and unlock your watch? Every time I try it starts the 3 hrs over. I’m getting so frustrated! I can’t do the update on my watch without entering the passcode but the stupid watch won’t let me enter it. I’ve tried the hard reboot many times, it does nothing. Just starts the 3 hrs over again. I put it on the charger and it’s fully charged.

This just happened to my watch today 2/13/24. I was listening to music and it started stopping and changing stations and once I realized it was my watch the screen was flashing different apps and trying to enter passwords which locked me out of my watch for hours. I did a hard reset but still is locked for the next 3 hours. Hopefully that does the trick. If not, not sure what to do.

I also had similar problems last night. it was a bit scary. luckily no emergency number was called. latest update installed, hard reset performed, icloud password and privacy settings reset performed. I hope Apple has an explanation for this issue or is conducting an investigation into this behavior.
