How To Enable Adoptable SD Card Storage On Galaxy S7 & S7 Edge – (No Root Required)


Adoptable Storage on Samsung Galaxy devices is an extremely useful feature that solves storage as well as partition issues for the users of Galaxy phones and tablets. In this post, we’re going to discuss in a simple step-by-step guide below how to enable adoptable storage on Galaxy S7 & S7 Edge smartphones. Samsung for some strange reason took away adoptable SD card storage option in previous Android firmware version for Galaxy devices. But following a huge user uproar, Samsung relented and brought back this much cherished feature back in Galaxy S7 and S7 Edge phones.

Although Samsung has brought back Micro SD card storage option back in Galaxy S7 and S7 Edge, but it also quietly pushed another fan favorite feature of Android Marshmallow in the background – the adoptable SD card storage feature. Those who are not well familiar with Adoptable storage, its a feature in Android Marshmallow firmware that lends your phone the ability to consider external storage as a part of the system partition, and hence, part of the device’s internal storage.

Using an expandable external micro SD card as an internal memory comes in quite useful on so many occasions. If you’re among those Galaxy S7 or S7 Edge on Android Marshmallow users, you can use the instructions below to enable adoptable SD card storage without root. Yes, its possible to get adoptable storage on Galaxy S7 or S7 Edge phone without no root required. Rooting an Android device may not be everyone’s cup of tea, so it would’ve been unfortunate if those users had to first root their device in order to get adoptable storage feature enabled. Thankfully, that’s not the case as we’re going to show you below.

Samsung hasn’t removed the adoptable storage completely from the system level, it has just hidden it by disabling it from the UI interface. You need to perform some system tweaks in order to enable adoptable storage to treat microSD card as a part of internal storage. If you’re comfortable with system modification process, see the guide below.

How To Enable Adoptable Storage on Samsung Galaxy S7 / S7 Edge:

See the steps in a guide below to learn how to enable adoptable storage on Galaxy S7 and S7 Edge without root. For this purpose, you’ll need a PC with ADB tool installed on it to get adoptive SD card storage on Galaxy S7 & S7 Edge without root.


Before moving forward, make sure following conditions are met.

  • Backup microSD card data as the process below will wipe out current data on the external SD card.
  • Go to the device Settings, tap on the ‘device build number’ 5 times in a quick succession to enable Developer Options. Enable USB Debugging in Developer Options.
  • ADB and Fastboot with drivers installed on PC Windows or MAC.

Steps To Get Adoptable SD Card Storage On Galaxy S7 and S7 Edge

Step 1 – Connect your device to PC. Use original USB cable that came with your device to avoid connection failure issues.

Step 2 – Open ADB and Fastboot command prompt on PC and type:

adb shell

sm list-disks

Step 3 – When you enter the second command, it will start searching for any available disks for adoption.


Step 4 – In the command prompt, Disk ID is in 000:000 format.

Step 5 – Now, here, you need to decided whether you want to treat entire microSD card as a part of device’s internal storage, or just a portion of SD card as an internal storage.

Note: If you set a portion of SD card as internal storage, it will enable you to save data as normal. You can still plug SD card in or out to access data saved on conventional SD card.

Step 6 – After deciding how much percentage (or all) of SD card you want to set as a part of device’s main internal storage, type the following commands in ADB command prompt (first command is to set 100% of SD card as internal storage, and the second command is to split SD card 50/50 between internal (regular) storage and SD card):

  • sm partition disk:000:000 private (in this command 000:000 will be replaced by disk ID and ‘private’ will be considered as 100% of SD card as adoptable storage).
  • sm partition disk:000:000 mixed 50

Step 7 – Wait for the partition to complete.

Step 8 – Once the partition is set, you can view the updated internal storage proportion in Settings > Additional Settings > Storage option.

Step 9 – That’s all.

Best things about enabling Adoptable storage on your device is any new apps will automatically install to the storage (internal or SD card) with more space available, however, you can manually change storage settings as well.

Update: According to official thread of this guide, it’s being reported that “for some reason, that total space isn’t reported correctly” when you set SD card as adoptable storage on Galaxy S7 / S7 Edge. But it shouldn’t be a big issue.
