Basics

Maintaining water and dust resistance

Your device supports water- and dust-resistance. Follow these tips carefully to maintain the

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.

•

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.

Basics

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

•

When you are roaming

Do the following when the device heats up:

•

Keep the device updated with the latest software.

•

Conflicts between running apps may cause the device to heat up. Restart the device.

•

Deactivate the Wi-Fi, GPS, and Bluetooth features when not using them.

•

Close apps that increase battery consumption or that run in the background when

not in use.

•

Delete unnecessary files or unused apps.

•

Decrease the screen brightness.

•

If the device overheats or feels hot for a prolonged period, do not use it for a while. If

the device continues to overheat, contact a Samsung Service Centre.

Basics

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.

•

Do not place the device in any areas that may overheat, such as on an electric heating

mat.

•

Do not store your device near or in heaters, microwaves, hot cooking equipment, or high

pressure containers.
