When you need to remove the SD card while the phone is on, unmount the storage card first to prevent corrupting or damaging the files in the storage card.
- Tap > > Settings.
- Tap Storage.
- Do one of the following:
- If the SD card appears under Removable storage, tap > Eject next to the card name.
- If your storage card appears under Internal storage, tap the card name, and then tap Eject.
Important: If the SD card is used as internal storage and there are apps that were moved to the card, you will not be able to open these apps after unmounting the card.
