On Android devices that support adoptable storage, you can format an SD card as internal storage and install apps there. Formatting permanently deletes the card’s data and ties an internally formatted card to that device, so back up first.
Copy every file you want to keep from the SD card before formatting it. Formatting permanently deletes data on the card.
2
Insert the card
Insert a compatible SD card into an Android device that supports SD storage and wait for the SD card detected notification.
3
Open the setup notification
Swipe down from the top of the screen and tap the SD card detected notification.
4
Choose the storage type
Choose Format another way when you want the card to act as internal storage. Choose Format for portable storage when you only want to store transferable files such as photos and videos.
5
Confirm the format
Read the deletion warning and continue only after confirming that the card is the one you intentionally backed up and want to erase.
6
Choose when to move content
After formatting, choose Move content now or Move content later if Android offers the choice.
7
Install or manage apps normally
Use the Play Store and Android’s normal app controls after setup. Whether a particular app uses the card can depend on the device and app.
8
Keep the card in this device
Do not remove an SD card formatted as internal storage to use it in another device. Google says it cannot be transferred between devices in that mode.

If it does not work
If your phone offers only portable storage, do not force an internal-storage setup. Portable storage can hold files but cannot install apps on the card.
If the card contains unexpected files or the device cannot recognise it, stop before formatting and verify the card and backup. Formatting is permanent.
