App permissions give you the ability to customize and control which capabilities you give apps. You can pick and choose which permissions to grant apps at the time of use.
Downloaded apps designed for Android® 6.0 (Marshmallow) and up only ask for permission the first time you use a feature rather than asking for permissions out of context.
Turning off certain permissions may result in basic features no longer working as intended.
From a Home screen, tap the Arrow icon to display all apps.
Navigate: Settings > Apps & notifications .
Tap App permissions.
Tap the appropriate permission type to modify (e.g., Body Sensors, Microphone, Location, etc.).
From the selected permission, tap any of the available apps (e.g., Google Play Services, My Verizon, etc.) to turn on or off .
If turning off a permission, from the "'if you deny this permission...' prompt, select 'Cancel' or 'Deny Anyway'.
