Hi.
Unfortunately I am also impacted by this.
Tested with:
Some facts about the devices
Tanita Scale= OK
HONOR CHOICE (in ears) = OK
Google Pixel Buds Pro (in ears) = OK
Omron Evolve (blood pressure) = OK
Oral B IO 10 (Toothbrush) = OK
Samsung Galaxy Watch 5 Pro (Smartwatch) = NOK / KO
Mercedes Benz E Class (car built 2023) = NOK / KO
So with two devices I have issues.
Unfortunately the smartwatch is kinda useless without a connection to the Samsung Health App. Here I have the same issues as the others. I tries again and again to connect, what will also drain the battery of the smartwatch. As Samsungs update policy is also not "that" bad, I would not expect that they did not see this coming.
There is no connection from the Smartphone to the car. Many of the functions I cannot use anymore. For instance that the car realizes it's me and fits the seat automatically to my position and lots of other things.
Side note: I understand your point that you would like to tshoot the situation to help us. But I definitely won't install any stock image on my phones just for testing purposes. Especially since I do not trust the backups of seedvault.
If I can provide anything else, beside install a stock rom, I am happy to help.
This is the first time since I use GrapeheneOS that I have issues. In other words: You guys rock and I highly appreciate your work. Thanks a ton!
