Nokia has today released a beta for HERE maps on the Samsung Galaxy Apps store. The two companies have entered into a licensing agreement to provide the mapping service to Samsung consumers at no extra cost.
The app is available for supported Samsung smartphones only, and is worth downloading simply because the service enables users to download maps for offline usage without having to play it safe with data package limits. It's a huge advancement over Google's own mapping service, which only allows you to download small segments.
It's worth remembering that HERE maps is currently in beta, so expect some issues along the way. For everyone else, you can look to see HERE maps available on your Android hardware in due course, especially since Nokia aims to compete against Google in the space. Nokia has provided more information on the new app over on the official HERE blog to help you get started.
