Water and Dust IP Ratings on Galaxy device

Samsung devices may be damaged if water or dust enters the device. For devices with an IP68 rating, follow these tips to prevent damage to your device and to help maintain the water and dust resistant performance:

• Do not immerse devices in water deeper than 1.5m and for more than 30 minutes.
• If you immerse the device in any liquid other than freshwaters, such as salt water, ionized water, or alcoholic beverage, the liquid will enter the device faster.
• Do not expose the device to water moving with force.
• The device should not be exposed to hot or soapy water, chlorinated water, water that is ionized, or saltwater. If the device has been exposed to water, dry it thoroughly with a clean soft cloth.
• If the device has been immersed in water or the microphone or speaker is wet, the sound may not be heard clearly during a call.
• 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.
• After the device has been exposed to water, you should wait until it is thoroughly dry before you charge it. The device will recognize if the USB port is still wet or damp and will show a water drop icon on the screen. You will not be able to charge the device until the USB port is dry.
• The touchscreen and other features may not have full functionality if used while wet.

No, it is not possible. The device is IP68-certified, but fingerprint recognition is blocked when the device is under water.
