My Apple Watch Ultra 2 has been acting sporadic

My watch went crazy today, flicking between different screens, typing its own texts, I couldn’t stop it or turn it off, had to just wait for battery to go flat to stop.

It's a bug in 10.3 on s9 and U2 watches.

Update phone to iOS17.4.1 and watch to watch OS 10.4


If a hard reboot does not fix it then Wipe Watch and set up again then update


Put Apple Watch on its charger.


Press and hold the side button until you see the screen with the power button in the upper-right corner, then let go of the side button. If your Apple Watch has an earlier version of watchOS, you see the Power Off slider instead of the power button.


Press and hold the Digital Crown until you see the red Reset button.


Tap Reset, then tap Reset again to confirm. 


After Apple Watch unpairs completely, you can pair again. Remember that you'll need the Apple ID and password that were used to set up the watch.

Update

Hi to all! I have this problem also and have posted here before. Mine acted up after 10.4 update was installed.

I called Apple and was spoke with an Apple watch tech. I was told if I send my watch in for repair, I will lose the Blood Oxygen sensor in it! He stated that they will not update our watches we have now to remove the Blood Oxygen sensor feature in it! We get to keep it!

I believe this a software problem because the watch does this very sporadic as it only happened to me three times since I bought it right after Christmas. My wife has a watch 9 and hers has no problems. The ( has the same problems.

I told them I will wait for awhile for more updates to come. And if it fails then I will have to make a decision if I want to lose the Blood Oxygen sensor in it or just reset the watch!

If anyone has sent their watch in for repair, please reply to me if it is fixed and if you lost the Blood Oxygen sensor! Thank you

This happened yesterday. I took it off and it was auto trying passcodes. I immediately ran and put it on the charger. It stopped the madness, but I was locked out for 1 minute for all the attempts. Once I got back in, the phone would NOT acknowledge me trying to power it off. It took me about 5 minutes to finally get it to power off. It's been fine since I turned it back on.

I had a really strange experience on the evening of April 1, 2024. While I was at the office, my watch started acting up in the weirdest way! It was jumping from app to app, setting countdown timers, going off with alarms, and even using random numbers as a passkey multiple times until it required a 60-minute wait to unlock. I thought my watch had been hacked because it wouldn't even let me turn it off. I attempted a hard reset by holding down the dial and side button for 10 seconds, but it just restarted immediately. It was a very unsettling experience.

Same issue here

then my iPhone started to call phone numbers (from my favorite list ) randomly

folks in different timezone - not happy


this builds on previous software issues: like any call would go through from the phone to me watch and the line was open

I spoke to genius desk twice and the agreed this is a major issue (like when you are on a business zoom call). They could reproduce the issue - but not solve it

in essence : this is not the product I bought

software updates +/- AI learning changes the features

i consider returning the ultra 2 - and get a Timex watch 😆

To day 4/16/2024 this is the third time my watch had done this! I was driving and it affected my music on my iPhone through my car then it made the siren go off, it was clicking and was going to dial 911! Maps suddenly started a destination. I took it off my wrist and it was still going nuts! It is fully up to date on software updates.

I have unpaired it and paired it the second time it did this as per your instructions. It seemed to have fixed it. But now I can't get into it because it is locked out for 17 minutes. Then after 17 minutes it starts trying to unlock and locks out again. It will not power done on (even force shut down)my wrist or charger using your procedures. I shut off my bluetooth on my phone and will wait till battery dies! But i'm afraid it will try to call 911 again! So the software update didn't repair it!

I tried that like ten times If the power button would come on it would disappear before I could press it or I pressed it while it was in the screen and it did nothing. Sometimes it would go to the slide to power off button but it wouldn't slide at all and then disappear! As I said I let it sit in my drawer until the watch battery died sometime today.
If you tried the standard reset a I describe it on the charger and it failed so many times, then I still suspect the hardware.

Apple Watch is not, and should never, be regarded as a medical device. If you have serious blood oxygen issues you should not rely on this watch, it was never accurate to better than 2% either way. It’s a non-medical indicator for normal people to suspect they may have a problem to be investigated, not a medical monitor for diagnosed people.

You must work for apple! 2% accuracy Pulse -OX is fine for me! Since Apple lost the right to sell the watch with Pulse-OX sensor I don't want to lose that feature. Second it is sold as a DIVE WATCH EN13319 certified, An internationally recognized standard for diving accessories. "Apple Watch Ultra 2 puts a bona fide dive computer on your wrist. Made for recreational snorkeling, scuba diving and free diving down to 40 meters!" So if it fails underwater divers lives might be in jeportly! So putting it in a glass of water overnight, It better not leak water! Now pull this post like you did on my other one That I just asked him it still has Pulse-OX and if it won't leak! But at least you read it!

I don't pull posts, the moderators do.
Stick your own watch in a glass of water but asking someone else to do it is irresponsible and somebody on the team noticed.
Get your watch fixed. The ban was for selling watches 9 and U2 in USA with that feature, no ban on the feature itself.

As I stated this Quote right from Apple  The Apple Ultra2 watch is sold as a DIVE WATCH EN13319 certified, An internationally recognized standard for diving accessories. "Apple Watch Ultra 2 puts a bona fide dive computer on your wrist. Made for recreational snorkeling, scuba diving and free diving down to 40 meters!" So If it can't handle a glass of water, how is it going to handle 120 feet underwater!!!

I have swam with my watch! It is good physical therapy for my me. You can look up diving as physical therapy for chronic pain and for O2 saturation. At a depth of 66 feet, I'm inhaling 3x the amount of air I would inhale at the surface.

Apple is selling this watch as waterproof down to forty meters so they would have to fix it under warranty if it doesn't survive a glass of water!!

You either work for apple or more then likely reported my post!

But I'm not a mean person and I mean when I say Good luck with your COPD I hope you have a full life!
