What to do if your Samsung Galaxy S7 or S7 edge gets wet and will not charge

It might seem obvious to some, but others may not think about their latest water resistant IP67 and IP68 Samsung Galaxy devices when they get wet and why they aren’t charging. It can be a stressful event when someone gets a message saying their $700 or $800 smartphone will not charge.


Samsung recently announced an alert about its water resistant Galaxy S7 and S7 edge, and what you should do to avoid damage to your device if it gets wet.

Samsung Android devices will not charge if moisture is present in the USB charging port. This is a preventative measure added to prevent corrosion. Corrosion within the USB charging port can lead to other more serious issues over time – including malfunction or non-function of the charging port.

A pop up message displays in the event a charger is plugged in while moisture is present in the USB charging port. Wireless charging is NOT affected by moisture or foreign material in the USB charging port.

Don’t fret, if you have some time, just let the phone dry out. It will eventually dry out. Or you can simply use a wireless charger since that doesn’t use the charging port.


If moisture does get in the USB charging port follow the recommendations below:

Do Not stick any objects into the USB charging port. This can result in damage to the charging mechanism.

    • Water will naturally dry or evaporate from the USB charging port within approximately 1 to 2 hours.
    • Gently shake the device and/or blow into the USB charging port to help remove water or moisture from the port.
    • Don’t use heat guns or hair dryers as excessive heat is never good for your device.
    • Do not use pressurized air cans since high pressure can force moisture deeper into your device.
