Unfortunately the latest update (0.18.10) didn't fix it yet. ZTE Blade L3, Android 5.0.2, pretty stock Android. Just guesswork, but could it be a positioning issue of the button? E.g. a negative position prefix could throw the button off-screen unintentionally...?
That's pretty strange, we still can't reproduce it.
