Is the button touching on the shell anywhere ?
no
Is it protruding/flush or sticks in a little from the shell ?
its in pretty deep, I can set it to mode one holding it in my hand, it will turn green and spin as usual and stop when eyes are blocked. If i tilt it so the front/switch is facing up it will start flashing orange as in changing the mode. So basically, if I hold it downwards the button falls down I think and pushes in automatically.
Is the screw you need holds in the battery door or the self tapping screw in the shell itself above the battery door ?
screw above battery door (not the one to hold battery door in)
What colour door do you need...?
black
