Have a Huawei MediaPad M5 with Android 8,
As mentioned above, I want to keep filming when I minimize the app. So open another app in full screen. Does anyone know?
I don't think that's possible. The only thing would be to open the apps in a split screen and then to make the camera app as small as possible…

That's how I solved it! That's why there are split-screen apps like "screens"!
