How to Add Layers to a Map on an Android Phone
You add details to a map in the Android’s Map app by applying layers: A layer can enhance the map’s visual appearance, provide more information, or add other fun features to the basic street map, such as the Satellite layer, as shown.
The key to accessing layers is to touch the Navigation Drawer icon in the lower-left corner of the screen. The navigation drawer displays several layers you can add, such as the Satellite layer shown. Another popular layer is Traffic, which lists updated travel conditions.
To remove a layer, choose it again from the navigation drawer; any active layer appears highlighted. When a layer isn’t applied, the street view appears.
