Oxygen reading stuck ever since latest update

[userKPRLiS9TY8]

Ever since I updated my watch to the latest big update on April 15th, my Galaxy watch 7 will get stuck on measuring oxygen. 

It starts at 0% and goes all the way to 99% and then stays at 99% indefinitely. I have to close it and try it again. My factory reset my watch but nothing fixes it. Is anyone else having this issue with the new update of Galaxy watch 7?

Nothing I did fix it. They finally gave me a label and I sent it in. It now works. It's strange because it only stopped after an update. I don't understand why a software update could break it, but it had to be hardware fixed.

Same here with my S7 ultra. It stopped working after last update. Nothing works. Resetting the entire watch didnt help. I cant monitor blood oxygen anymore. Come on samsung!! Fix this please. It always been working..and now you broke it

@Samsung are you guys going to fix this? We are multiple users who have lost this 02 function since the last update. An update should not break your watch like this. Please fix this

Did you actually put in an error report? They are not going to fix what they don't know about. This is a peer-to-peer user forum and Samsung engineers do not act on postings to the forum even if they are lurking. They need to see the logs of the individuals having the issue, so that they can determine the cause and then create a patch - or tell you it's completely user error.

I have put in multiple reports, they acknowledged the problem, but not the scope and relation to the software update . They have now advised they can not assist, and that I have to send the watch to a physical technician at a repair centre. Doesn't look like they are planning a software patch or that they CAN deploy one to fix what the last update broke.

I contacted them months ago with an error report and was told they were well aware of the problem and were working on a fix. They've given up.

Same here... Any update?

[userKPRLiS9TY8]

Here is the definitive answer. For some reason as you said they do not acknowledge that their software caused a problem. They required me to send it in. I reluctantly did. I believe it went to texas. It took almost two weeks to get it back.. but, it came back working perfectly. The report that I had said they had to repair some things with the sensor. I don't know what to believe, but it doesn't matter. This was the only way I could get it fixed, and Samsung fixed it. My advice is simply to suck it up and send in your watch.
