LG G2 4.4.2 Update

I updated my LG G2 a couple weeks ago but i cant seem to find some features I had before. Wheres the options you had when you swiped up from the home button (quickmemo, google search, voice)? Also how do you take a screenshot (quickmememo)? On the old version i believed you had to hold the volume up and down button at the same time. That doesn't work anymore, can somebody with a updated LG G2 fill me in?
