Galaxy Watch Series devices after One UI 8 update bugs

[Khemikhall]

After updating my watch 4 classic to the new One UI 8 I have noticed these issues listed below. Does anyone here notice them too?

■ Wrist detection seems to be broken. Having to keep putting in pin when screen goes dark.

■ Knock knock feature won't work after device power down. For it to work it has to be toggled off then on and then re-selecting the App to associate it with. (This also affects my watch 6 after update)

■ Sleep detection not working at all. Before I had no issue and sleep recording was accurate.

@Khemikhall I have a feeling that the Sleep detection issue is related to the wrist detection issue. If it doesn't detect your wrist, it won't record any sleep.

After the update, did you wipe the device cache on the watch? 

[Khemikhall]

I think you might be right. Sadly I've tried device wipe and partition clear and haven't resolved the issues.

A lot of devices have bugs after that update. I have a Watch 4 Classic and still haven't received it. I believe they pulled the update to fix those bugs because you can pull it up on Sammobile.

Do you happen to know if theres a way to revert the update?

I'm having the same issue with the sleep detection. I have checked as much as I can to try to figure it out but nothing helps. I wish they would fix it.
I got tired of putting my pin in every time I wanted to look at my watch so I turned off the pin. It fixed that part but that's it

These and also the heart rate function no longer works - even when it does manage to catch a rhythm, its totally wrong. Logging a workout is a nightmare - if I select treadmill for example, it opens the step count, heart rate, or weather screens instead of launching the workout. When I can get it to launch the correct workout, it randomly stops and also the caloric burn is off by 100s of calories because it wont measure heart rate. This is seriously negatively impacting my fitness training and overall health since I can't adjust my caloric intake to match my output. If it's not resolved soon I will be switching to Garmin.

My Samsung Watch 4 no longer displays my messages in full since the last update a couple weeks ago. All I get on my watch now is a notification that a new message has been received.

Recheck your settings for notifications in the Wear app.  Sometimes updates move settings so things get turned on or off.  Open the Wear app. Go to Watch settings/notifications/advanced settings and toggle on show details automatically when checking notifications after an alert.  Regardless, you should still get the details when you tap on the notification card.  Also, clear the watch's cache partition.

I've been in my settings several times over the last couple weeks, but to no avail. I depend on my watch allowing me to read my messages and really would like to see a fix for this.
