Comment 8 for bug 1392306

Related, it seems the bq aquaris manual is wrong about how to receive calls:

    Receiving Calls
    To pick up an incoming call, simply tap the green receiver icon you see
    on the screen when the phone is ringing.

According to an aquaris owner [1], one has to swipe.
