The Halo Go, Drive and Pro have share the same smartphone app that enables you to live preview, playback recordings and download recordings with the Pro offering extra functionality in the form of GPS and telematics data. If you are experiencing issues with not being able to use live preview, playback footage or download videos try turning off your "Mobile Data" in your phones settings before using the Halo app.
