•
The device may require a connection to a Wi-Fi or mobile network when using some apps
or features.
•
Content (high quality content) that requires high CPU and RAM usage will affect the
overall performance of the device. Apps related to the content may not work properly
depending on the device’s specifications and the environment that it is used in.
•
Samsung is not liable for performance issues caused by apps supplied by providers other
than Samsung.
•
Samsung is not liable for performance issues or incompatibilities caused by edited
registry settings or modified operating system software. Attempting to customise the
operating system may cause the device or apps to work improperly.
•
Software, sound sources, wallpapers, images, and other media provided with this device
are licensed for limited use. Extracting and using these materials for commercial or other
purposes is an infringement of copyright laws. Users are entirely responsible for illegal
use of media.
•
You may incur additional charges for data services, such as messaging, uploading and
downloading, auto-syncing, or using location services depending on your data plan. For
large data transfers, it is recommended to use the Wi-Fi feature.
•
Default apps that come with the device are subject to updates and may no longer be
supported without prior notice. If you have questions about an app provided with

water- and dust-resistance of your device. Failure to do so may result in damage to your
device.
•
Do not immerse the device in fresh water deeper than 1.5 m or keep it submerged for
more than 30 minutes. If you immerse the device in any liquid other than fresh water,
such as salt water, ionised water, or alcoholic beverage, liquid will enter the device faster.
•
Do not expose the device to water moving with force.
•
Do not open the device’s covers when the device is in water or in very humid places, such
as swimming pools or bathrooms.
•
Do not open the back cover using wet hands or when the device is wet.

Basics

•
The rubber seal fitted to the back cover is an important component of the device. Take
care when opening and closing the back cover to avoid damaging the rubber seal. Also,
ensure that the rubber seal is free from debris, such as sand or dust to prevent damage to
the device.
•
The back cover may be loosened if the device is dropped or receives an impact. Ensure
that all the covers are properly aligned and tightly closed.
•
If the device is exposed to fresh water, dry it thoroughly with a clean, soft cloth. If the
device is exposed to other liquids, such as salt water, swimming pool water, soapy water,
oil, perfume, sunscreen, hand cleaner, or chemical products such as cosmetics, rinse it
with fresh water and dry it thoroughly with a clean, soft cloth. If you do not follow these
instructions, the device’s performance and appearance may be affected.
•
If the device has been immersed in water or the microphone or speaker is wet, sound
may not be heard clearly during a call. After wiping the device with a dry cloth, dry it
thoroughly before using it.
•
The touchscreen and other features may not work properly if the device is used in water.
•
If the device is dropped or receives an impact, the water- and dust-resistant features of
the device may be damaged.
•
Your device has been tested in a controlled environment and certified to be water-
and dust-resistant in specific situations (meets requirements of classification IP68 as
described by the international standard IEC 60529-Degrees of Protection provided by
Enclosures [IP Code]; test conditions: 15-35 °C, 86-106 kPa, fresh water, 1.5 metre, 30
minutes). Despite this classification, it is still possible for your device to be damaged in
certain situations.

Device overheating situations and solutions
When the device heats up while charging the battery
While charging, the device and the charger may become hot. During wireless charging or fast
charging, the device may feel hotter to the touch. This does not affect the device’s lifespan or
performance and is in the device’s normal range of operation. If the battery becomes too hot,
the charging speed may decrease or the charger may stop charging.
Do the following when the device heats up:
•
Disconnect the charger from the device and close any running apps. Wait for the
device to cool down and then begin charging the device again.
•
If the lower part of the device overheats, it could be because the connected USB
cable is damaged. Replace the damaged USB cable with a new Samsung-approved
one.
•
When using a wireless charger, do not place foreign materials, such as metal objects,
magnets, and magnetic stripe cards, between the device and the wireless charger.
The wireless charging or fast charging feature is only available on supported models.
When the device heats up during use
When you use features or apps that require more power or use them for extended periods,
your device may temporarily heat up due to increased battery consumption. Close any
running apps and do not use the device for a while.
The following are examples of situations in which the device may overheat. Depending on
the functions and apps you use, these examples may not apply to your model.
•
During the initial setup after purchase or when restoring data

Precautions for device overheating
If you begin to feel uncomfortable due to the device overheating, stop using the device.
When the device heats up, the features and performance may be limited or the device may
turn off to cool down. The feature is only available on supported models.
•
If the device overheats and reaches a certain temperature, a warning message will appear
to prevent device failure, skin irritations and damages, and battery leakage. To lower the
device’s temperature, the screen brightness and the performance speed will be limited
and battery charging will stop. Running apps will be closed and all calling and other
features will be limited, except for emergency calls, until the device cools down.
•
If the second message appears due to a further increase of the device’s temperature, the
device will turn off. Do not use the device until the device’s temperature drops below the
specified level. If the second warning message appears during an emergency call, the call
will not be disconnected by a forced shut down.
Precautions for operating environment
Your device may heat up due to the environment in the following conditions. Use caution to
avoid shortening the battery’s lifespan, damaging the device, or causing a fire.
•
Do not store your device in very cold or very hot temperatures.
•
Do not expose your device to direct sunlight for extended periods.
•
Do not use or store your device for extended periods in very hot areas, such as inside a
car in the summertime.

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.
