One of the major features of Android 6.0 Marshmallow is adoptable storage, which formats and encrypts a microSD card to work as part of the internal storage. It basically lets you increase the size of the internal storage, and the biggest use of this feature is having more space for installing apps, which can only be done on the internal storage on Android. Samsung, unfortunately, hasn’t implemented adoptable storage on the Galaxy S7 and Galaxy S7 edge (or on Marshmallow for other devices), but it continues to offer the option to move apps to the external storage.
This is the same option that has existed on Samsung devices for long, but the way you move apps to the SD card is somewhat different on Marshmallow (and the Galaxy S7 and Galaxy S7 edge). How do you do it? Well, just follow the steps below. Keep in mind that it’s up to individual apps to support moving to the external storage, so the steps below can only be applied on apps that do enable the option.
Step 1: Head into your phone’s settings, then tap the Applications option. On the next screen, select Application manager to see a list of all your installed apps.
Step 2: Then, find the app that you want to move to the SD card, and click on its name in the list.
Step 3: Here, below the Uninstall button, tap on the Storage option.
Step 4: If your app supports moving to the SD card, you should see a CHANGE button on the screen that pops up after you select Storage in the above step.
Step 5: Tap the CHANGE button, then select SD Card. This will bring you to the export menu, where you can hit the MOVE button at the bottom to start moving the app to the SD card.
That’s it! Once done, simply hit the back button to go back to the applications list, or hit the home button to go to the home screen. Do note that Android doesn’t support fully moving an app to the SD card, so some of the app’s data will continue to reside on the internal storage. Taking out the SD card at any point might make these apps stop working, so if you are ever swapping your microSD card for a new one, make sure to move each of the apps back to the internal storage before doing so. Then simply repeat the above steps to move those apps to your new SD card.
