I was trying to check the version of x940bt software and tried holding the upper left hand of the screen down in the System information screen and I'm not getting the service menu for the application version.

did you try it a few times? for some reason it took me about 4 times to touch the right spot, but once you find it it works. you have to hold it for about 3 full seconds

X930BT with 940 firmware, but same thing
