the real thing that annoys me very much in 99% of apps, is that they are not adapted for 1080p, spotify too, but not in resolution but in 8.1's screen space compiling, you may have noticed that bar on bottom of screen is smaller on 1520, but it isn't in facebook messenger app, spotify, im+ and lots more, but it's small in skype, original phone apps and menus and etc. so facebook chat is COMPLETELY UGLY, spotify not that much, but it lags. really, IT LAGS ON 1520 800 snapdragon. what the hell. rrrrr
