Samsung Galaxy S7 and LG G5, the main smartphones at Mobile World Congress 2016, lack of support for an important feature introduced by Google in Android 6.0 Marshmallow. Adoptable Storage can unite the phone memory and the one from microSD card in a single partition. Basically, the user is free of media questions when, for example, downloading files from the Internet, because the two works as a whole.
Adoptable Storage eliminates a problem faced by devices with a small storage capacity, 8 to 16GB: lack of space for applications. Although many smartphones models with small internal storage capacity have microSD card slots, there are larger apps that cannot be moved on the external memory.
For example, some streaming music applications cannot be moved to the card, and the user has to download offline playlists to the phone memory.
Samsung has decided not to use the Adoptable Storage on Galaxy S7 as this way microSD cards cannot be moved from one phone to another. Android 6.0 Marshmallow users must choose, for external storage if they want it to be in “portable mode” or “internal storage mode”. In the first case, Storage Adoptable does not work.
