Helpful tips if your device heats up
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

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.

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 water deeper than 1.5 m or keep it submerged for more
than 30 minutes.

•
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.
•
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.
•
If the device is exposed to clean water, dry it thoroughly with a clean, soft cloth. If the
device is exposed to other liquids, such as salt water, ionized water, or alcoholic beverage,
rinse it with clean 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.
•
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 has been immersed in water or the microphone or speaker is wet,
sound may not be heard clearly during a call. Wipe the device with a dry cloth or dry it
thoroughly before using it.
