Android 9 Pie vs Android 8.0 Oreo Walkthrough: What’s New

Simplified Location Settings

I'm not a fan of this next change, and you won't be either. Google changed the location settings on Android Pie. The idea here is your location settings are now very easy to understand, and simplified. 

You can turn location settings on, or off, and that's all. Those are your only two options. On Android 8.0 Oreo (and everything before) you had multiple choices, including a battery saver mode where location options were turned on, but in a state that used as little battery as possible. 

Now, it's all or nothing moving forward.
