Hello Richard. I’m not familiar with Samsung tablets, but I do know that the OLFI camera will record in two selectable file formats – .mp4 and .MOV – these are selectable from the VIDEO FILE FORMAT of the Settings menu
If your tablet doesn’t support either of these formats natively then there are many video converters around that will convert
Are you able to play back your videos from your camera itself by going into playback mode? (Main Menu>Playback (2nd menu option)
Also, when you say you can see them on your tablet, but you cant play them. Is it just that they are buffering, or did you get some error message appearing when you attempted to play them?
