Why did the phone start this "slide to unlock"

[Android Central Question]

I have a nexus 6p, my wife has a pixel and hers has done it since it was new. However mine just started doing this I assume a new version of android. I have 8.0.0

It used to be when I wanted to use the phone I would use the fingerprint or pin- now I have to "slide" to unlock the screen, usually with some slot machine game or other garbage on that start screen. It jumps randomly to various ads and apps that it wants me to use/get, and I have also noticed the battery doesn't last, and I have noticed it going into do not disturb- but I did read the cause of that.

This is all new over the past week or 10 days. What is this thing? This is by far the WORST and what can I do to get the old phone interface back? thank you!

Not an Android thing. It's an app you have installed. Unfortunately (and you can check the numerous and seemingly endless threads here) there's no easy way to pinpoint these. Usual culprits are File Managers and Battery Optimizers, but in the end you need to find which app is popping these up. Sometimes in the ad there is a menu button or cog icon that you can use to disable the 'feature' (charging manager is what most call it); and remember that even if the option is disabled, if the app updates it might re-spawn it into being active (which is why most people don't realize which app it is because they haven't installed anything new recently...it just updated).

Thank you. I started dumping "normal" apps- bar code scanning, text free (which I've had forever), and its gone. Its frustrating because I don't know what it was, but I don't really care because its now gone. Thank you so much for your help.

Glad you got rid of it! And yeah, it's unfortunate more devs are starting to resort to these intrusive ads for revenue They should at least warn you upfront (of course they won't because otherwise no one would install their apps).
