I had an mp4 video which used to play on the S2.
I then installed some apps, including ES MEdia player, and now the mp4 won't play, reporting, "unsupported file type."
Also, I can't play mpeg videos.
Anyone shed some light please? Is there any slight chance that I might regain mp4 playback after removing ES Media player?
(unlikely, but I know very little about android, so there is nothing to be lost by asking people more knowledgeable than myself.)
