This has nothing to do with the type of device people are using. It is a
Zoom problem. Could we have an answer from Zoom as to what THEY have
done to cause this problem please?
I have had the same problem on my Windows 10 Linx tablet, since
upgrading Zoom last week. The camera is rotated at the start of every
meeting. I manually rotate it, but then if I turn my camera off and back
on during the meeting, it has rotated again...
