Ok. The N73 is great (now I have the firmware upgrade). But I am always accidentally putting the phone in gallery mode with the side button (next to camera button).
When the phone is in the car cradle it will flick to gallery Landscape mode on every bump in the road. Very distracting while driving.

Just holding the phone between palm and forefinger while thumbing the keys also does the trick.

This could have been avoided at design by simply putting the button higher up for the left hand use. Do the designers ever try prototypes?!

This button is only useful while being used as a camera. That is, when the shutter cover is open.

So how about a fix:

IF button_pressed && shutter_closed DO nothing
