How to protect your Samsung Galaxy device after water exposure

Last Update date : 25 July 2026

If your Galaxy phone is exposed to water or other liquids, internal damage or corrosion may occur even if the device appears to work normally. The steps you should take depend on whether your device supports water resistance. Follow the guidance below to help reduce damage and protect your device after water exposure.

Note:

  • Improper cleaning or drying methods may cause discoloration, corrosion, or permanent damage to the device.
    • Do not use heat sources such as hair dryers to dry your device.
    • Do not use chemical cleaners, abrasive materials, compressed air or external heat sources to clean your device.
  • We recommend visiting a Samsung service centre to have your device inspected for possible damage, even if it appears to work normally after water exposure.

If your Galaxy device supports water resistance and is exposed to dirty water or liquids such as soap water, oil, perfume, sunscreen, hand sanitiser, cosmetics, or alcohol-containing liquids, follow the steps below.

Important: Follow these steps only if your Galaxy device is water-resistant.

Step 1. Rinse the device in clean water for 1 to 3 minutes to remove residue, salt, or foreign materials.

Step 2. Wipe the device with a soft, clean cloth and dry it completely.

* Do not connect a charger or accessories until the device is fully dry.

  • Some functions, such as touch input, may not work properly when the device is underwater.

If your Galaxy device does not support water resistance, follow the steps below immediately.
