What video files are supported by my phone if I wanted to drag and drop some on the SD card?
avi, mkv, m4v for sure. Try others. If the built-in player does not play something, just installl free MX Player and it will play everything you throw at it.
Imagination is the only limit here.
Yup, if the stock video player won't play it, then MX Player most likely will. If MX Player won't, then DICE Player probably will. The only thing that MX Player hasn't played for me are .mts AVCHD files from my professional video camera. And DICE plays them with ease.
I can play my GoPro 1080p@60 videos on it, my laptop can't even play them. I've not found a video it will not support yet. I also have MX player.
Yep. Along with MX, your can play about every normal codec there is.
