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 or 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.

Be careful that liquids and dust does not enter the device

Galaxy Z Fold3 5G and Z Flip3 5G support IPX8 rated water-resistance. Care must be taken to maintain the water-resistance of your device and to prevent the damage to your device.

  • Do not immerse the device in fresh water deeper than 1.5 m for more than 30 minutes. If you immerse the device in any liquid other than fresh water, such as salt water, ionized water, or alcoholic beverage, liquid will enter the device faster and it may result in damage to device.
  • 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, it may cause damage to the device and the device’s performance and appearance may be affected, also it may not be covered by warranty.
  • Do not expose the device to water moving with force.

In addition, these devices are not dust-resistant. Exposure to small particles, such as sand, may cause damage to the device, such as scratches or dents on the screen.

Note: IPX8 is based on test conditions for submersion in up to 1.5 meters of freshwater for up to 30 minutes. Not advised for beach or pool use.

Do not remove the screen protector film

It is recommended that you do not remove the screen protector film, and do not install other films or stickers, as doing so may cause device damage. Unapproved screen protectors may cause the sensors to malfunction.

Keep a safe distance from magnetic objects 

Your device contains magnets. Please keep a safe distance between your device and objects that may be affected by magnets, such as credit cards and implantable medical devices because the objects may be damaged or disabled by the magnets in the device. If you have an implantable medical device, consult your physician before use.

Ensure the device is folded and positioned correctly when wireless charging

When wireless charging, fold the device and place the device's back on the center of the wireless charger. Since the product has a built-in magnet and the location of the wireless charging coil is different depending on the device, adjust the device's position as shown below.

Otherwise, the device may not charge properly or may overheat. If you place it in a different position or orientation than the picture, it may slip due to the inclination of the device and magnetic force.
