How to kill apps in Flyme 4.X

I have a Meizo M2. First, when I swipe screen to unlock, I usually end up either in settings or camera. Why? I want to see the home screen with app icons. Second, how do I kill apps? On my old iPhone I simply held down home button and swiped open apps upwards to kill. Advice please.

Yo you just have to swipe from bottom to top to unlock your phone correctly. Also to see recent apps swipe from bottom of the screen to top when using phone :)
