How do I locate Google Settings, or better Android Device Manager Settings on Android 5.0.2 MIUI 7.0? I have trouble locating Google Settings.
Official help documentation advice doesn't apply. Maybe since I have MIUI 7.0? I'm looking for Android Device Manager Settings.

Edit: This answer isn't related to the question actually. Please read the post by @sinchan for correct information and then mine for extended info. 

Android Device Manager which comes builtin has no specific settings AFAIK. You just need to login using Google Account and manage all the devices under that account like Locating, Erasing, Locking, Ringing the devices remotely. For Android device manager to work properly keep the GPS and Mobile Data/WiFi turned on.   

Additionally visit Google My Account > Device Activity for other options.
