Howdy moleman,

Thank you for reporting this issue. There have been previous reports of other users having this issue as well. Start-up movies are not yet implemented for Android yet. It is something that we are currently working on. I am unsure of the timetable on when this issue may be resolved.

Thanks for your patience and have a great day!
