I just used another another paper other than the Verizon Big Red Logo. The lag from landscape to portrait mode is reduced greatly!!!! Almost 0 lag. Just another weird tips.
Sorry, i was too excited for getting no lagging from Landscape to portrait mode. Well, i just replaced the wallpaper to something other than the Verizon wallpaper, and it reduced the lagging time by much.
I wonder why. Maybe due to the size of the original Verizon wallpaper. Give it a try and see what you all think.
