Getting started
Use only a microSD card.
•
Some SD cards may not be fully compatible with the device. Using an
•
incompatible card may damage the device, the SD card, or the data stored in it.
Use caution to insert the SD card right-side up.
•
Ensure that the ejection pin is perpendicular to the hole. Otherwise, the device
•
may be damaged.
When you remove the tray from the device, the mobile data connection will be
•
disabled.
If the card is not fixed firmly into the tray, the SD card may leave or fall out of the
•
tray.
If you insert the tray into your device while the tray is wet, your device may be
•
damaged. Always make sure the tray is dry.
Fully insert the tray into the tray slot to prevent liquid from entering your device.
•
The device supports the FAT and the exFAT file systems for SD cards. When
•
inserting a card formatted in a different file system, the device will ask to
reformat the card or will not recognize the card. To use the SD card, you must
format it. If your device cannot format or recognize the SD card, contact the SD
card manufacturer, a Samsung Service Center or an authorized service center.
Frequent writing and erasing of data shortens the lifespan of SD cards.
•
When inserting an SD card into the device, the SD card's file directory appears in
•
the My Files → SD card folder.
Removing the SD card
Before removing the SD card, first unmount it for safe removal.
1
Open Settings and tap Device care → Storage.
2
Swipe to the left to access the SD card page.
3
Tap → Unmount.
Do not remove external storage, such as an SD card or USB storage, while the
device is transferring or accessing information, or right after transferring data.
Doing so can cause data to be damaged or lost or cause damage to the external
storage or phone. Samsung is not responsible for losses, including loss of data,
resulting from the misuse of external storage devices.
