For some of you the didn't know what this do is to enable the ambient display mod that is built in on lollipop(n6) but disabled on nexus 5.
Ambient display is the ability to wake up the screen via device pickup or a notification arrival although because of some limitations on hardware side it won't work properly via device pickup on our device but will work 100% percent on notification arrival.
Ok Enough with the chit chats.
