I find it quite weird that my old galaxy nexus has much better in app performance than the note 2. The note 2 seems to lag and jerk while scrolling in apps such as instagram, and the new play music app. The scrolling on my galaxy nexus is just a lot faster and smoother. Does anyone know why this is happening? Could it be because of the larger screen of the note 2? Would loading a stock android rom, such as pacman or CM 10.1, help fix this performance issue in apps? Thanks!
