After flashing the image available about 1 week ago (when this topic was 3-4 pages long) i refreshed the other days the repos and updated the available packages, added bluetooth support :-), and also applied the mcetool commands for double tap.

I use this now as my main phone and functionality is pretty ok with the known limitations, of course. Thanks a a lot for the image!

Double tap works (it is more 3+ taps - but that's ok). Now the only thing is that the phone display wakes up without any obvious reason (once or twice a minute), like after the double tap. Does anybody experience the same behaviour?
