Using the latest Stellarmate OS and Android app on Samsung Tablet S6 Lite (WiFi only, no magnetic sensor)
It has some minor quirks to get used to, but as a veteran Linux power user, nothing too bad to abandon Stellarmate.

1. I went through the video tutorial to try out the Polar Alignment Assistant. Auto routine works like a charm using 600x mount speed, but when it comes to zooming in/out and panning the image to a bright star and adjust the correction rectangle, i actually can't do any of these actions, neither in minimized nor fullscreen display of the periodicallly captured/refreshed image.
Any ideas?

2. As an alternative, can i just switch to VNC/Kstars->Ekos and do the PA there, continue with Stellarmate app afterwards?

3. As the VNC connection is rather slow, would it make sense to use an external WiFi Dongle+Antenna instead of the RPi4 internal one?
Another workaround (at home) would be to connect via VNC over Ethernet Powerline, connected to my WiFi home router. I could then even use INDI compatible clients to connect to the RPi4. When i'm out in the field i would be limited to WiFi-Hotspot mode, of course.

Thanks in advance.
