When using the speakers, such as when playing media files or using speakerphone,
do not place the device close to your ears.
•
Be careful not to expose the camera lens to a strong light source, such as direct
sunlight. If the camera lens is exposed to a strong light source, such as direct sunlight,
the camera image sensor may be damaged. A damaged image sensor is irreparable
and will cause dots or spots in pictures.
•
If you use the device with its glass or acrylic body broken, there may be a risk of
injury. Use the device only after it has been repaired at a Samsung Service Centre.
•
If dust or foreign materials enter the microphone, speaker, or receiver, the device’s
sound may become quiet or certain features may not work. If you attempt to remove
the dust or foreign materials with a sharp object, the device may be damaged and its
appearance may be affected.
•
Connectivity problems and battery drain may occur in the following situations:
–
If you attach metallic stickers on the antenna area of the device
–
If you attach a device cover made with metallic material to the device
–
If you cover the device’s antenna area with your hands or other objects while
using certain features, such as calls or the mobile data connection
•
If the area around the rear camera is covered with accessories, such as a screen
protector or stickers, unwanted noises may occur during calls or media playback.
•
Do not cover the proximity/light sensor area with accessories, such as stickers or a
cover. Doing so may cause the sensor to malfunction.

Charging the battery
Charge the battery before using it for the first time or when it has been unused for extended
periods.
Use only Samsung-approved battery, charger, and cable specifically designed for your
device. Incompatible battery, charger, and cable can cause serious injuries or damage to
your device.
•
Connecting the charger improperly may cause serious damage to the device. Any
damage caused by misuse is not covered by the warranty.
•
Use only USB Type-C cable supplied with the device. The device may be damaged if
you use Micro USB cable.
•
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.
•
When using a charger, it is recommended to use an approved charger that
guarantees the charging performance.

•
Do not place the device on the wireless charger when conductive materials, such as
metal objects and magnets, are placed between the device and the wireless charger.

Battery charging tips and precautions
•
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 losing power during a data
transfer, always use these apps after fully charging the battery.
•
Using a power source other than the charger, such as a computer, may result in a slower
charging speed due to a lower electric current.
•
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 touchscreen may not
function. If this happens, unplug the charger from the device.
•
While charging, the device and the charger 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 you charge the device while the multipurpose jack is wet, the device may be damaged.
Thoroughly dry the multipurpose jack before charging the device.
•
If the device is not charging properly, take the device and the charger to a Samsung
Service Centre.
SIM or USIM card (nano-SIM card)
Insert the SIM or USIM card provided by the mobile telephone service provider.
You can insert two SIM or USIM cards so you can have two phone numbers or service
providers for a single device. In some areas, data transfer speeds may be slower if two SIM
cards are inserted in the device than when one SIM card is inserted.
Some services that require a network connection may not be available depending on
the service provider.
