Galaxy J7: How Do I install, remove and format the memory card correctly?

Last Update Date : Apr 25. 2018

Your device accepts memory cards with maximum capacities of 128 GB.

Depending on the memory card manufacturer and type, some memory cards

may not be compatible with your device.

• Some memory cards may not be fully compatible with the device. Using an

incompatible card may damage the device or the memory card, or corrupt the data

stored in it.

• Use caution to insert the memory card right-side up.

• The device supports the FAT and the exFAT file systems for memory cards. When

inserting a card formatted in a different file system, the device asks to reformat the

memory card.

• 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.

1. Remove the back cover and battery.

2. Insert a memory card with the gold-coloured contacts facing downwards.

1 Remove the back cover and battery.

2 Pull out the memory card.

3 Replace the battery and back cover.


*Do not remove the memory card while the device is transferring or accessing

information. Doing so can cause data to be lost or corrupted or damage to the

memory card or device. Samsung is not responsible for losses that result from the

misuse of damaged memory cards, including the loss of data.


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.

On the Home screen, tap Apps Settings Storage Format SD card FORMAT SD



*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.

Turning the device on and off

Press and hold the Power key for a few seconds to turn on the device.

When you turn on your device for the first time or after performing a data reset, follow the onscreen

instructions to set up your device.

To turn off the device, press and hold the Power key, and then tap Power off.


• If your device is frozen and unresponsive, press and hold the Power key and the

Volume key down simultaneously for more than 7 seconds to restart it.

• Follow all posted warnings and directions from authorised personnel in areas

where the use of wireless devices is restricted, such as aeroplanes and hospitals.
