2.6-kernel hwvalidation:


3.7 kernel: 

	evtest /dev/input/aux

The button part sitting on the PCB has a built-in spring with some small force.

If the button is stuck this means that the plastic case has more friction than
the button's spring force.

Please check if it works if you remove the display cover.

If yes, you can try to scratch a little off the plastic parts of the transparent
AUX button part and/or the black plastics. Until it can be moved.

Hope this helps.
