When I shoot photos with my main camera it works fine. But when I switch to video mode it says the app can’t establish a connection with the camera.
I already let it repair by my provider and been told they replaced the device, but the new phone got the same problem. Thus I think it could be a software problem.
One more detail: The picture and videos shot with my front cam are upside down.

Had the same and I found out that decreasing the video quality from 1080p to 720p in the settings resolves things without resorting to third-party apps.
For the record, I have the “old” camera.
