I am using firmware 6.4.42 on the UHD3000 and Android version 1.10.20. I have already contacted support with the problem, but unfortunately this has not been successful. I have tried 3 different Android devices and the round play button is no longer displayed when a movie is playing. So I can't fast forward or rewind the movie. It still works on iOS, but I would like to use my Android phone. Does this work on your Android devices? Thank you
