Where are Nokia's maps? Right HERE, in the Samsung Galaxy Apps Store
One of the big advantages of Nokia's mapping app is that it allows you to use it without an internet connection. Think about all of the data that you could save by being offline while using the mapping application.
The app is available for those Samsung handsets powered by Android 4.1 or higher, and weighs in at 36.82MB. The HERE beta also includes Glympse, which lets you select a period of time during which your location can be viewed by others. Once Glympse is turned off, your location is hidden.
