am serious , i am not going to sit here and have the back n forth but you can look it up yourself , a good high quality standard rip is just as good as a 720p rip on a screen that small ,yea for a phone its large screen but overall its really not, it only starts making once a very noticeable difference when you get into large computer monitors and tv. Read up on pixel density, screen size, frame rate and resolution.
and the only reason am saying on this is not to shyt on your phone, the note 2 is the best android phone out right now, but its to save you on file size , if your downloading 720p movie specifically cause you think there going to look better on your phone them ur wrong.
also i hope were not confusing hd movies with "hd" apps and game specifically made to run at certain resolution and frame rates optimized for phones
