N3rdTek Is it normal behavior to have GMSCompat running almost 24/7?
On my phone it does not run ("No battery use since last full charge ").
What could or would potentially cause it to run and have no "Stop" button under Active Apps?
Since it is part of the sandboxed Google Play system, if you installed that and have apps using it then it will run (often).
Since it shouldn't be running unless requested, I'm not surprised it doesn't have a "Stop" button. It's a system service, not an app.
