So ive transfered over the USB two formats of video, mp4 and avi, and they dont show up anywhere on my device. I read that they will only show up in the gallery app, however there is no gallery app on my device.... i go under apps, and there is no icon for gallery, only personal video, which my files are not located. Any ideas? Its easy to transfer video on any of my other android devices, whats the problem here?
