If your Android device supports USB C or microSD you can view your TeslaCam footage directly on your Android device.
In some cases, the version of Android you have will play the footage without any issues.
If you are having issues viewing the video files on your Android device, try the VLC Player app, which can open just about any type of file.
It is available for free from the Google Play store: https://play.google.com/store/apps/details?id=org.videolan.vlc
