Brother, the mobile phone itself is a vertical screen, of course, there is no such problem.
It also works in landscape mode with no issue. Khadas is the only box I have had this problem within 5+ years.
I have enabled usb debugging as per https://docs.khadas.com/edge/SetupADB.html and then ran the command as above. I don’t know what else to do… How do I enable a usb connection with the box?
