to be honest I used to like watching movies on the phone when i moved from the OV (tiny screen) to the Triumph (huge clear screen) but i never loaded any files on SD.
i used netflix with wifi.
then it faded and I stopped watching movies on the phone. wasnt fun anymore.
the EVO 3D totally changed that, I try to ONLY watch 3d movies on it now, I try to get a new one every week.
if its formatted correctly in qhd or 720, it looks REALLY nice on this screen.
the only downside is holding it, but i watch while in bed with headphones and i have a little stand that holds the screen in the right position.
if your going to watch movies on a phone, THIS is the way to do it. try loading a SBS 3d movie to it.
