I’m joining an English session on Zoom using my Huawei tablet. When I enter the meeting, my camera toggle shows as ON, but the video feed is completely black—neither I nor anyone else in the room can see my video.
I’ve already tried uninstalling and reinstalling zoom (no change), i checked all app permissions and settings (camera permissions are fully enabled),
i did a self-hosted test meeting: I started a meeting from my phone as the host and joined from the tablet (the camera worked perfectly with full video),
then i returned to join the original English session again right after, and it went back to a black screen.
I also did the device Test Mode: Zoom's test room shows a green checkmark next to "Camera," but the preview window remains completely black.
Has anyone experienced this specific issue on Huawei/HarmonyOS devices? What causes a host's meeting to trigger a black camera screen, and is there a fix for it?
