[Samsung Galaxy Watch 6] quoctoanuet:
I just realized that when I opened the Bluetooth settings from the watch, it showed nothing, no nearby devices, no connected devices, whether I connected it to both my Android and iPhone or didn't connect to any of them. Does this issue happen on your watch?

I did use ADB to disable some of the apps, which I listed below. However I don't think its the problem.

I also tried `pm enable` all of them via ADB again, and after that, I did a factory reset, but none of them worked.
