I'm sure that issue can be rectified with some enhancmenets for example :
- While Offscreen, reduce screen sensitivity
- If Offscreen AND touchwake event occurs, check light and proximity sensor, if both are dark and proximity==1 DO_NOT_WAKE_SCEEN
As for the dude who said the home button wakes the screen, that might be true,
but When you handle the Note with one hand, it is very uncomfortable to click the home button, skipping it would be awesome.
Galaxy Note II - Everything just works, and beautifully.
