My Huawei P40 fell into the water and can t receive a signal, what s going on?

The first step: power off the mobile phone, many mobile phones will turn on automatic protection after detecting that the mobile phone is water, directly shut down and then prevent the mobile phone from short circuiting, at this time if you find that the mobile phone has been turned off, don't panic to test whether the mobile phone can be used, don't turn on the next step directly, if you find that the mobile phone can still be used normally, that is, there is no power outage, then don't be happy, you still need to power off the mobile phone, because if you don't power off in time, it may form a short circuit on the motherboard, As long as the motherboard is short-circuited, then your mobile phone really has to go to the repair shop.

Step 2: Remove all external devices, including SIM card slots, data cables, headphones, phone cases, etc., this is to prevent the current at the interface from causing secondary damage, and also to prevent things like the phone case from making the evaporation area of the mobile phone larger, because if the evaporated area becomes larger, this water ingress is particularly difficult to handle.

Step 3: Deal with the problem of water ingress into the mobile phone, find a direction that can drain the water out, and shake the mobile phone hard, this step needs to control the strength, the water in the small mobile phone can not be thrown out, if the strength is too large, the mobile phone may be thrown out, and then you will not only have to repair the mobile phone into the water, but also may repair the mobile phone screen, the back of the mobile phone and so on. The most important thing to pay attention to is to clean the water in the screen, if the screen leaves water droplets, it will also leave traces after drying, affecting our visual experience, for some corners of the water, we can use cotton swabs or paper towels and the like, do not use a hot hair dryer, many users may feel that the speed of using a hair dryer to dry is faster, but the hot hair dryer may bring the risk of glue melting, but the cold hair dryer can try it.

Step 4: Stand the phone to let the water evaporate, if the previous step has not seen obvious water droplets, the phone will be left to stand for more than 24 hours, do not be anxious to test whether the phone can be used, otherwise the above steps are completely in vain, if you can still see a significant small amount of water vapor, we can use rice or desiccant and so on to assist in the operation of water. Wait until 24 hours later, we can try to turn on the phone, under normal circumstances, the phone can still be turned on normally, if it can't be turned on, congratulations you may have a chance to change the phone, of course, you can still go to repair.

If the motherboard is flooded, turn off the phone immediately, disassemble the back cover, take out the motherboard, blow it at a constant temperature with a hot air dryer for about half an hour, and then put it in a cool place for two days to start it up.

In order to reduce your losses, it is recommended that you turn off your mobile phone and bring the relevant proof of purchase to a nearby Huawei customer service center for repair. You can use the Huawei official website to find the address of a Huawei Customer Service Center near you.

Precautions after water and liquid ingress in the mobile phone:

1.Do not move or shake your phone frequently after the liquid is ingested to avoid moisture spreading inside the phone.

2.Do not blow with a hair dryer or bake at high temperatures (including microwave heating) after liquid infusion, so as to avoid liquid being blown into the phone and damage the phone by high temperatures.

3.Mobile phones are made of delicate electronic components, and there is a potential risk after liquid ingress, so please keep your phone turned off.

4.If you don't have a backup of your data, there may be a risk of data loss during repairs. After you go to the Huawei Customer Service Center, you can consult with a staff member to help you evaluate whether you can back up your data.

We are sorry to hear this, and in order to reduce your losses, we recommend that you deal with it as follows:

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.

Note: If you don't have a backup of your data, there may be a risk of data loss during repair.

1.Reducing the amount of time your phone is in contact with water will minimize the damage to your phone.

2.The longer the phone is immersed in water, the more harmful it will be to the phone's earpiece, microphone, screen, and motherboard. Remove your phone from the water, quickly dry it to indicate water trails, and remember not to try to turn it on.

3.After taking out the mobile phone, quickly remove the battery, most mobile phones are integrated, and the battery needs to be handed over to a professional to operate. If you feel that the water in the phone is almost shaken off, don't try to turn it on, use a hair dryer to keep the temperature of your hands not hot and blow on the hole in the phone, three minutes each time, blow three times, and then start to dry.

4.When the phone is buried in rice, it can suck up all the water droplets and water vapor inside the phone. You can also prepare some desiccant or drying box for emergencies.

5.In general, the main thing is a quick power cut, which cuts off the power between the motherboard and the battery. Quickly clean up the liquid inside your phone. Have you learned?

Be sure to shut down the machine first, otherwise it will burn out the internal parts, and go to Huawei after-sales service for testing in time.

Hello, if there is water, the system is affected and needs to be repaired after the sale.

If the mobile phone falls out of water, turn it off as soon as possible, and let it air dry naturally, or soak it in high-concentration alcohol and then air dry, you can use a hair dryer to blow it.

If you can't receive the signal, it may be that the SIM card is short-circuited, or the water in the phone has not dried up, so let it go for a while and wait.

The most direct thing is to take it to the repair shop to deal with it.

This is not sure yet, because you just took it out of the water, and now it can be used normally, but I am afraid that the water will faint in it, and it will affect it in two days.
