I really want to buy this phone but I see just a little input lag throughout the UI when I watch videos. I'm not telling about choppy FPS, I'm talking about the time it takes for the screen to react to your touch. I wanted to know if there is any screen input lag when it comes to gaming on the phone. I currently have the galaxy note II and the input lag is absurd, so I definitely do not want to get another phone like that. I'd be grateful for any response you guys could give me, thanks.
