Formatting and Removing MicroSD card from Samsung Phone

Last modified : May 02. 2019

If you are upgrading your Galaxy device or experiencing some reading issues with your MircoSD card, you may either need to reformat the card or insert it into another Galaxy to ensure the card is working correctly. If you do not properly de-install the SD card from your Galaxy phone or tablet, you could possibly corrupt the files saved on the memory card or cause the card to become unusable. Whenever switching SD cards, it is essential to correctly unmount or format the memory card that way you do not lose any data saved or damage the card for further use.

Please Note: Settings and steps are based on Android OS Version 9.0 (Pie), if your Galaxy device is operating on a previous software, check out our guide How do I format my microSD card? for step-by-step instructions on Galaxy devices operating on Android OS Version 8.0 (Oreo), 7.0 (Nougat) and 6.0 (Marshmallow).

Removing the memory card

Before removing the memory card, first unmount it for safe removal. Launch the Settings app and tap Device care → Storage → 3 dots → Storage settings → SD card → Unmount.

1 Insert the ejection pin into the hole next to the tray to loosen the tray.

Ensure that the ejection pin is perpendicular to the hole. Otherwise, the device may be damaged.
2 Pull out the tray gently from the tray slot
3 Remove the memory card.
4 Insert the tray back into the tray slot.

Caution: Do not remove external storage, such as a memory card or USB storage, while the device is transferring or accessing information, or right after transferring data. Doing so can cause data to be corrupted or lost or cause damage to the external storage or device. Samsung is not responsible for losses, including loss of data, resulting from the misuse of external storage devices.

Formatting the memory card

A memory card formatted on a computer may not be compatible with the device. Format the memory card on the device.

Launch the Settings app and tap Device care → Storage → 3 dots → Storage settings → SD card → Format.

Caution: Before formatting the memory card, remember to make backup copies of all important data stored in the memory card. The manufacturer’s warranty does not cover loss of data resulting from user actions.
