Basics
• The device supports the FAT32, the exFAT, and the ext4 file systems for memory
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 a memory card, you must
format it. If your device cannot format or recognize a memory card, contact the
memory card manufacturer or a Samsung Service Centre.
• Frequent writing and erasing of data shortens the lifespan of memory cards.
• When inserting a memory card into the device, the memory card's file directory
appears in the My Files → SD card folder.
Removing the memory card
Before removing the memory card, first unmount it for safe removal.
Launch the Settings app and tap Battery and device care → Storage → → Advanced →
SD card → Unmount.
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 Battery and device care → Storage → → Advanced →
SD card → Format.
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.
