My LG G3 has specs which claim it can shoot 4k videos. Maybe it is a misprint as it seems more like 2K. Not that I am planning any cinematic extravaganzas. http://www.phonearena.com/phones/LG-G3_id8347
Looks to me like Sony (which used to be the butt of many jokes RE: software updates) has been doing pretty well in that department recently. If my memory serves me right, the 2013 Xperia Z has been updated to Lollipop this year.
