Take the phone to the repair shop and disassemble it for replacement parts; I can't eliminate the obstacle of water ingress into the mobile phone, and you should turn off the phone in time when the water enters to avoid causing other parts in the machine.

Immediately remove the back cover and remove the battery after the phone falls into the water. This is very important!

If you can disassemble the machine, you can disassemble and blow it, to ensure that there is no moisture on the surface of the motherboard and screen, and to blow it away, do not blow it in one place.

At this time, you should turn on the electric blanket, put the mobile phone screen down on the electric blanket (no battery), and then cover it with a quilt and dry it overnight.

If the inside of the phone is dirty, you can wipe the motherboard and the soaked place with anhydrous alcohol, and if it falls into dirty water, use anhydrous alcohol to clean the inside of the phone, mainly the motherboard and the display.

If the above methods do not work, then you can only send it to the repair shop for repair!

1.No matter what kind of water the phone falls into, you should remove the phone battery directly as soon as possible (instead of pressing the power off button)!

2.Use undusty napkins, cotton balls, cotton swabs, etc. to absorb all the water that can be wiped off outside.

3.If it is dropped into clean water, you can clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together (provided that you have anhydrous alcohol). If it falls into the sewage, it should be cleaned immediately, and the visible dirt should be cleaned first, and the impurities attached to the components should be brushed off with a brush.

4.Use a hair dryer to swing over a long distance to dry the moisture on the surface of the machine. (Be careful not to blow too close or to one place for a long time).

5.Use an electric blanket to bake for another night and you're ready to go!

The correct way to deal with the water inlet machine: When the mobile phone accidentally enters the water, the first thing is to directly remove the battery (very important), do not press the shutdown button to take it again, otherwise the power supply of the motherboard is very easy to burn out. Then take it to a professional repair shop as soon as possible for water removal treatment.

In particular, dirty water such as sewage, urine, and seawater is extremely corrosive to the motherboard. Fast in about two hours can mold, patina. Even if it's clean water, don't think that if you dry it with a hair dryer, you'll be fine.

You can't blow it inside. As long as there is no battery installed after water ingress, it has not been turned on or off. The odds of a fix are great.

If the battery is installed without the motherboard water removal treatment, it is easy to burn out the power supply and power amplifier. It is also easy to burn out the CPU, font library and other hardware when booted.
