this is something i just discovered, i don't know whether its been mentioned before but i will say anyway. When i slide the top half of the pre i always wondered why i have never pressed on something on screen while doing so, even tho my thumb is on the screen! The sliding action must disable the touchscreen for a second or so. Ive never noticed this on another phone so its just another plus point to my pre that and the magnetic earphones which always manage to impress me
