You should be able to just tap on the center of the screen which will dismiss the bar (at least that's how it works on a normal Android device). If that doesn't work, try swiping the bar down off the screen. If that also doesn't seem to work, let me know and I'll run some tests on my Lumi.

Thank you for your fast and clear answer
Tapping in the middle of the screen alternates between being able to edit the song and going back to the display (but always with the navigation bar showing at the bottom.
And swiping the bar down off the screen has no effect.  :/
