I am using Noka 3 mobile with beta version android 8. I have noticed in my camera app, can't able to record video. Since then, I have planned to roll back to Android 7.1 stable version for Nokia 3. Hope this feedback help your before going for Andrioid 8 upgradation. Also developers please fix the issue. I have posted already the same in Feedback app.
