I took two videos on my Samsung Galaxy S8 while using my Gear VR for the quest (pair of jacks in hand one on table) I pressed share then record and the record light went on. I have the videos (date and time) but I can't play them. It gives me a message "unable to play video" They are listed as a MP4. What do I do? I would like to get my chips for 2 quests (200,000). I can send in the video or you can tell me how I can play it. I don't think it is a codecs problem.
