Not sure why no one is using this super simple solution (it seems.) Earlier another user posted this solution as well that I thanked, and it does work. In lollipop on Nex 10 I couldn't go back to swipe or none, but this does work! Even though I already fixed my issue because of the earlier solution, just wanted to say thanks anyway. Maybe this solution is just too simple to follow because most of the replies are to the very complicated ways to do it. Weird..... But not as weird as Google making it a bit more complicated to do. I forsee a lot of uninformed carrier personel telling customers to reset their carrier branded devices that get 5.0 in the coming months (years), to bring back "none or swipe", then they probably won't use security anymore. Again, not sure why Google did this.
