1. Remove the battery.

2. Remove moisture.

Don't use a hair dryer to dry or take it to the stove to bake, as the heat from the outside can damage the delicate electronics inside the phone. Don't try to turn on the phone, many users will subconsciously press the power button after taking out the phone to see if the phone can still be turned on, this is the wrong approach, even if the phone itself is not damaged, once turned on, it may cause the result of burning the motherboard, or the motherboard is short-circuited!

The correct way to do this is to wipe it quickly with a clean towel to make sure that water does not run into the charging port, headphone jack, etc. If you find that the water has flowed down the connector or through the gap into the phone, carefully blow the water out with compressed air, and never blow deeper and deeper.

3. Drying treatment.

You can prepare some desiccant or drying box, collect the desiccant, and seal the soaked mobile phone with the desiccant. Or put your phone under a slight heat source such as a desk lamp or spotlight to let the moisture slowly dissipate.

Wait until the phone is completely dry, try to turn it on and try to operate the functions.

4. If it can't be turned on or there is a fault in the attempted operation, it is recommended to go to the network engineer to use professional instruments and equipment for inspection and maintenance.

Install the power management, multi-** driver, and fast commotion shortcut key driver.
