When the phone is flooded, the screen flashes and turns off again, is it broken?

If you are using a Huawei phone, we recommend that you do the following:

1. Please try to place your phone in a dry and ventilated place and use a paper towel to blot the water stains on the surface of your phone.

2. If the phone is turned on, press the power button to turn it off; If your phone is turned off, don't try to turn it on.

3. Please take out the SIM card and microSD card.

4. Take your phone to a Huawei customer service center as soon as possible to avoid unnecessary losses.

Precautions: 1. Do not move or shake the mobile phone frequently after entering the water, so as to avoid the spread of moisture inside the mobile phone.

2. Do not bake with a hair dryer or stove after entering the water, so as to avoid the liquid being blown into the inside of the mobile phone and damaging the mobile phone at high temperature.

3. Some mobile phones can be turned on and used normally after simple treatment, but the mobile phone is composed of precision electronic components, and there is a hidden risk after water ingress, so it is recommended not to try to turn it on.

4. During the after-sales maintenance process, data may be lost.

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 and then 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. Patina can grow in about two hours. 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 high.

If the battery is installed without the motherboard water removal treatment, it is easy to burn out the power supply.
