Check 1. Turn off your device
If your device is waterlogged, make sure to turn it off. Moisture in the device can cause serious damage or corrosion to the mainboard. If the battery is removable, quickly remove the case, battery, USIM, etc. If your device is a newer model without removable batteries, immediately turn off your device.
Check 2. Remove moisture
After turning off your device, quickly dry off your phone. Remove as much moisture as possible from the battery, USIM, memory card, etc. using a dry towel or a clean cloth. Check also the areas where water can enter, such as the earphone jack or charging port. Use a cotton bud to ensure complete moisture removal.
Check 3. Remove foreign debris
If liquids such as drinks, seawater, or chlorinated pool water, etc. get in your device, it is extremely important to remove the salinity or impurities as soon as possible. This is because the foreign debris may speed up the corrosion of the mainboard. After turning off your device, take out any removable parts, soak in clean water for approximately 1~3 minute, then rinse. Afterward, follow Check 2 and thoroughly dry your device.
Check 4. Air dry
After removing the moisture or impurities, leave your device to dry in a well-ventilated area or in the shade with cool air (from a fan). Air drying is recommended for devices that are waterlogged. Please note that attempting to rapidly dry your device using a hair dryer or hot air may damage your device.
Check 5. Check the waterproof rating
Most Galaxy models are dustproof and waterproof and feature the highest rating of IP68. Although the highest ratings support up to 30 minutes of waterproofing at a depth of 1.5m, it should not be used in deeper areas or areas with high pressure. Your device may become waterlogged if it is at a depth of 1.5m for longer than 30 minutes.
If you want to check Samsung phones with an IP68 rating, you can check more at 'Water and Dust IP Ratings on Galaxy device' with Samsung Support.
Moisture may be present in your device even after a period of drying, so it is best not to power on your device until you visit a service center to have it checked.Please bring your waterlogged device to an Authorized Service Center as soon as possible.
