Many people refrain from using the Google Maps because they fear it will take up too much mobile data. The good news is that your Samsung Galaxy S8 device will let you download a series of maps from this app, store them on the phone, and use them later, with the same Google Maps app, only that offline, without taking any mobile traffic.
By default, all the downloaded offline maps will be automatically removed from the phone within 30 days IF you haven’t updated them in the meantime! That happens, of course, for reasons of relevance, since roads can change frequently and maps have to be up to date!
The good news, however, is that you can keep these downloaded maps up to date through an automatic process!
