I just received the July update for the One UI 8 beta on my Galaxy S25 Ultra. The next day my Galaxy watch 5 pro LTE was no longer connected to my phone through Bluetooth and the option was unavailable. When I tried to connect through the Bluetooth menu it opened the Wear app and just said not connected. I reset my watch and after that I was unable to add the watch at all. Tried several times resetting the watch and rebooted as well. Each time I went to add the watch it would get to 70% in the setup screen and then say error. I repeated the process multiple times with no luck. Tried every possible option, checked forums, contacted support. Nothing worked. I decided to backup my S25U and do a factory reset. After that I was able to connect to my watch though Bluetooth and remotely. Next morning, watch is working standalone but no longer connected through Bluetooth. Same problem again. There is no option to connect it. Also my Samsung account is not on my watch. It says login through phone but phone says it's not connected. I did another factory reset on my S25U. Reset the watch. Same thing, watch connected but would not show that it was logged into my Samsung account and the phone says update Samsung account app on the watch. I try to but it just opens wear and says the same thing. It's an endless loop of resets. This morning same problem! Bluetooth no longer an option for the watch and I can't login to Samsung account on the watch. This is very frustrating! It must be some bug that shows up at night. I hope One UI 8 standalone is available soon. I've never had a beta that was this horrible. I haven't been able to use my watch for over a week. I think next time I'll opt out of the beta. Previous ones were ok but this one is pretty bad and Samsung support is no help whatsoever. Hope someone else has a solution but I'm betting it's just terrible bugs within the beta.
I had the same problem to which I involved samsung support due to phone and watch was under warranty. They removed in several times and sent the watch ultra in for repairs multiple times. The bug was never fixed but they replaced the watch ultra and problem is solved so far.
