So the other day I went into the gallery and instead of the photopile usually shown on the main screen, there was a YouTube video. Listed as "Unknown, uploaded Thursday." I've never seen the video before, did not take it, did not download it, and I've never left my phone unattended. (I've only had it for a week!) I can't delete the video, remove it, hide it, anything. It's extremely frustrating, especially since I use my gallery so much. I've run through file managers trying to find it and remove it, and it just doesn't exist. If I tap the video it loads a screen, (claiming it's a Guren Lagann fandub, I don't even watch that show) but the video itself won't buffer or play. Anyone have any ideas on this one?
