http://forum.xda-developers.com – Hello. i imported a nexus 7 tablet from a local market because its still not officialy available here yet. anyway everything is fine except when i want to move an icon to the right page or anything that come close to the right edge of the screen. i tried to use a drawer app to see what is the problem, it seems when i draw a line from left to right, the line stops just before it reach the right edge of the screen. now if i only draw a vertical line on the right edge, it will work. so i am not sure what is the issue when i swipe/draw a line / move an icon from left to the right edge.
