Just tested with
Phone:
Smartwatch:
Result: NOK / KO
Notes: Issue persists. The behavior did not change at all. Repetetively the connection switches fast between devices and saved devices. Installed BETA, Rebooted, Application alignment started (took quite a while, same as with the first STABLE version which caused the issues. That was also not the case for my device before), Rebooted again. Issue persists.
Remarks: It would be nice if the Devs could give more detailled information to us how to track the issue down. Which logs you need, what we can test for you on our side. Surely with the view on our data protection. As not every normal non tech user understands if he reveals sensitive private data with providing the logs.
Remarks_2: As I need a stable phone, and thats definitively the reason why I use and love GrapheneOS, I am not really about to test everything which will break my applications or connections. I do not like it to be a Guinnea Pig, nor have time for that. But I would be happy to spent some bucks that a Dev with the right knowledge can buy a Samsung Galaxy Watch 5 Pro to track down and fix the issue. At least if really none of the Devs has one already. But my assumption is that you guys do not use these devices at all :) I guess if all of the ppl who face the issues spent some bucks, we could provide a device for you. Just my two cents.
