As discussed earlier, the Adoptable storage feature was introduced by Google in the 6th version of Android OS (Marshmallow). This feature allowed users to use SD cards on the mobile phone as internal storage. But this feature had many drawbacks like the decreased performance of the phone and also has the risk of losing data if the external storage is not unmounted properly. For this reason, many phone manufacturers have disabled this feature in the later versions of the Android OS.

Steps to Use SD Card as Internal Storage on Android

If you are having Android Marshmallow as the operating system on your smartphone or later then you can use an SD card as internal storage by following this simple workaround.

  1. First of all, turn off your Android phone and insert the SD card into your phone and restart it.
  2. After your phone is restarted, go to the “Settings” app.
  3. Find and tap on the “Storage & USB” section.
  4. Select the name of your SD card to open the data stored in your SD card.
  5. Tap on the three vertical dots to open a drop-down menu.
  6. In the drop-down menu, tap on the “Storage Settings” option.
  7. In the next window, tap on “Format as internal”.
  8. In the next tab, select “Erase & Format” to confirm the process. This step will erase all the existing data on your SD card.
