Has the knock on function improved on the m8 with lollipop? I remember watching a review of the m8 when it released and you had to pick up the phone or at least move it in some fashion before the double tap to wake function would work. Has this been improved with lollipop, i have phone on desk a lot and being able to double tap to wake is a deal breaker to me (so used to it from my g2) or does it still require you move the phone first?
