Ok, so I'm running a Nexus 6 with stock Android 5.1.1 Verizon Build Number LMY48M. Last night I had the normal paginated app drawer where you swipe horizontally to scroll through your pages of apps. This morning on the way to work i was listening to Pandora over bluetooth, the phone then shut down (without any prompting from me). When it restarted the app drawer was no longer paginated and now scrolls vertically with all apps on one big page. From googling around this looks to be how the app drawer will be once Marshmallow is released, but I don't understand why it changed on my phone since I am still on 5.1.1. Anyone else have this happen recently?
