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.

Note:

  • Improper cleaning or drying methods may cause discolouration, 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 the microphone, speaker, or receiver is not completely dry, call quality may be affected.
  • Some functions, such as touch input, may not work properly when the device is underwater.
