Charging the battery
Use the charger to charge the battery before using it for the first time. A computer can be also 
used to charge the battery by connecting them via the USB cable.
Use only Samsung-approved chargers, batteries, and cables. Unapproved chargers or 
cables can cause the battery to explode or damage the device.
•	When the battery power is low, the battery icon appears empty.
•	If the battery is completely discharged, the device cannot be turned on 
immediately when the charger is connected. Allow a depleted battery to charge for 
a few minutes before turning on the device.
•	If you use multiple apps at once, network apps, or apps that need a connection 
to another device, the battery will drain quickly. To avoid disconnecting from the 
network or losing power during a data transfer, always use these apps after fully 
charging the battery.
Connect the USB cable to the USB power adaptor and then plug the end of the USB cable into 
the multipurpose jack.
Connecting the charger improperly may cause serious damage to the device. Any 
damage caused by misuse is not covered by the warranty.

•	The device can be used while it is charging, but it may take longer to fully charge 
the battery.
•	If the device receives an unstable power supply while charging, the touch screen 
may not function. If this happens, unplug the charger from the device.
•	While charging, the device may heat up. This is normal and should not affect the 
device’s lifespan or performance. If the battery gets hotter than usual, the charger 
may stop charging.
•	If the device is not charging properly, take the device and the charger to a 
Samsung Service Centre.
After fully charging, disconnect the device from the charger. First unplug the charger from the 
device, and then unplug it from the electric socket.
Do not remove the battery before removing the charger. This may damage the 
device.
To save energy, unplug the charger when not in use. The charger does not have a 
power switch, so you must unplug the charger from the electric socket when not in 
use to avoid wasting power. The charger should remain close to the electric socket 
and easily accessible while charging.
Reducing the battery consumption
Your device provides options that help you save the battery power. By customising these 
options and deactivating features in the background, you can use the device longer between 
charges:
•	When you are not using the device, switch to sleep mode by pressing the Power button.
•	Close unnecessary apps using the task manager.
•	Deactivate the Bluetooth feature.
•	Deactivate the  Wi-Fi feature.
•	Deactivate auto-syncing of apps.
•	Decrease the backlight time.
•	Decrease the screen brightness.

Using a memory card
Installing a memory card
Your device accepts memory cards with maximum capacities of 64 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.

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 
card

Before formatting the memory card, remember to make backup copies of all

excessive pressure to it with your fingertips.
•	The device may not recognise touch inputs close to the edges of the screen, which 
are outside of the touch input area.

(screen burn-in) or ghosting. Turn off the touch screen when you do not use the 
device.
•	It is recommended to use fingers when you use the touch screen.
