How to Add Layers to a Map on an Android Phone
You add details from the Maps app on your Android phone 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 in Satellite view.
The key to accessing layers is to touch the Layers button. Choose an option from the Layers menu to add that information to the Map app’s display.
You can add another layer by choosing it from the Layers menu, but keep in mind that some layers obscure others. For example, the terrain layer overlays the satellite layer so that you see only the terrain layer.
To remove a layer, choose it from the Layers menu; any active layer appears with a green check mark to its right. To return to Street view, remove all layers.
Most features found on the Layers menu originated in the Google Labs. To see new features that may be added to the Maps app, visit the Labs by pressing the Menu soft button in the Maps app. Choose Settings and then Labs to pore over potential new features.
The phone warns you whenever various applications access its Location feature. The warning is nothing serious ¯ the phone is just letting you know that an app is accessing the phone’s physical location. Some folks may view this action as an invasion of privacy; hence the warnings. Some see no issue with letting the phone know where you are, but not everyone feels that way. If you’d rather not share location information, simply decline access when prompted.
