Moisture may impact the performance of your device if not handled with care. Moisture may most commonly be accumulated inside the charging ports, under the screen, inside the headphone jack, and behind the camera lenses.

It is advised to protect your phone from moisture by placing it inside a waterproof zip-lock pouch while travelling in rainy weather. Further, kindly avoid using the phone with wet hands or charging the phone if it is wet. In case you find that moisture has accumulated in your phone, then follow the tips given below.

Warning: Don't use charging/USB port

We've detected moisture or foreign material in your charging/USB port.

Check your charging/USB port for any foreign material such as dust or debris. To prevent damage to your phone, don't plug anything in until the charging port is clean, the moisture is gone, and the notification is cleared.

To dry the port, shake out any moisture, then wait for it to dry, which could take several hours. You can speed up drying by pointing a fan or dryer (cool air only) at the port.

In the meantime, you can charge your phone wirelessly.
