Just thought of a much needed feature (unless its there and I can't see it!)...
It would be nice to be able to switch the light on without having to go into the camera.
Do sometimes this very useful as it was great on the K850i.
Found I needed it tonight walking to the pub down a dark path between fields!
I tried this and it doesn't appear to work. I still only get a display for every 10% is this just because the xperia will only report every 10%
Did you try only the cab installer or the copy® method with the dll file? Did you soft reset the X1?
