Yes, the camera is working perfectly in the latest TinkerOS. I've written a Python tool making use of the gstreamer plugin to record for a certain amount of time and the video is good. There was a major bug in the previous version but it was fixed.
However, TinkerOS doesn't provide support for WiFi USB dongles and I really need that, since the Tinkerboard only has 2.4ghz. The environment I'm using it in has a lot of other 2.4ghz WiFi access points and the 5GHZ band has only a few. Armbian does have support for some USB WiFi dongles but then the camera doesn't work. So at the moment I'm kinda stuck. One OS has a working camera, the other OS has a working USB WiFi. If I could, I would combine these two worlds :-)
