With the new updates and the ultimate videoplayer app I've gotten the device to loop some 5K 360-video content of mine. I would like to have the gallery where the videos are projected "controller free". There would be no controllers lying around anywhere. Sometimes I remember when starting the device, it could be operated with the volume controller buttons. Now, I can't seem to make that happen again. Can you force it to use the volumebuttons only for navigating. Thanks for the help!
