Preheat the dry rice cooker liner and wait for it to be set to the keep warm before putting it into the phone, and drying it on the heat saving setting for a while can perfectly remove the moisture inside the phone without damaging the phone.

The above is the specific solution to what to do if the Huawei mate30 mobile phone falls into the water, I believe you will soon be able to learn how to operate through the introduction of the above content.

Hello, the phone fell into the water, you should take it out as soon as possible, and then put it in the sun to dry, and wait until the moisture is completely gone before turning it on.

If you encounter similar problems in the future, you can follow the following ideas to solve them:

1. Finding problems: often living in the world, always in these kinds of contradictions, when some contradictions are projected into consciousness, the individual only finds that he is a problem, and asks to find a way to solve it. This is the stage where the problem is discovered.

From the perspective of the stage of problem solving, this is the first stage and the premise of solving the problem.

2. Analyze the problem: In order to solve the problems found, it is necessary to clarify the nature of the problems, that is, to figure out what contradictions there are, which contradictions, and what is the relationship between them, so as to clarify what results the problems to be solved, the conditions that must be met, the relationships between them and what conditions have been met, so as to find out the important contradictions and key contradictions.

3. Put forward hypotheses: on the basis of analyzing the problem, put forward hypotheses to solve the problem, that is, the solution that can be adopted, including what principles and specific ways and methods to take, but all of these are often not simple and ready-made, and there are various possibilities. However, putting forward hypotheses is the key stage of problem solving, and correct assumptions lead to the smooth solution of the problem, while incorrect and inappropriate assumptions lead to detours or lead the solution of the problem astray.

4. Verify the hypothesis: The hypothesis only proposes n possible solutions, and there is no guarantee that the problem will be solved, so the last step in problem solving is to test the hypothesis. In either case, if the test does not produce the expected result, a new hypothesis must be proposed and tested again until the correct result is obtained, and the problem is not solved.

1.Be sure to get it out as quickly as possible. Because the longer the phone is immersed in water, the larger the immersion area of the mobile phone, the greater the damage to the phone's earpiece, buttons, screen and motherboard.

In order to avoid losses as much as possible, once the mobile phone falls into the water, it must be fished out in time.

2. After the mobile phone is fished out of the water, wipe the water on the surface first. Knock on the point, never turn it on. Because the water is likely to have penetrated into the inside of the phone, once it is not cleaned up, it will cause the motherboard to burn if it is powered on again, so do not turn it on, it will only cause more serious damage and greater damage to the phone.

3. Next, the next thing to do is to remove the battery first. Regardless of whether your phone is on or off, try to remove the battery first if you can remove the battery, and don't forcibly disassemble the phone if you can't remove the battery. In that case, it's easy to be unclear-headed.

It is recommended to find a professional repairer to remove the battery to prevent other parts of the phone from being harmed.

4. Wait until the water in the mobile phone is almost cleaned, take out the hair dryer, keep the cold air as much as possible, blow the temperature not too high, blow slowly on the place where the water enters, and don't use hot air to blow in a hurry, because the high temperature of the hair dryer is likely to cause devastating damage to the sensitive components inside the mobile phone. The next step is drying. Desiccants and drying boxes should be available in every house, and if the water ingress is not serious, you can try to remove the moisture in this way.

No matter what brand of mobile phone falls into the water, the way of treatment is basically the same, the first step is to remove the water on the surface of the mobile phone with a absorbent paper towel, the second step is to use a hair dryer to dry the water in the mobile phone as much as possible, the third step is to put the dried mobile phone in a dry rice pile, fully so that the mobile phone has no moisture, and the fourth step is to charge and detect the mobile phone.

Don't deal with the water when the phone gets into the water, or go to Huawei after-sales maintenance to repair it.

Precautions. It is still troublesome for the mobile phone to fall into the water, so you must protect it at ordinary times!

I believe that many friends will put the water into the water after the mobile phone in the box, and then use rice to spread it, wait for 12 hours, we can go to buy a new mobile phone, who told you that the mobile phone into the water with rice? That's because unscrupulous traders want to sell more mobile phones, so they taught you to do it.

Let me teach you some correct methods, and you must not believe these rumors. The water ingress of the mobile phone is mild and moderately waterlogged.

Mild water ingress solution: Mild water accumulation means that after your phone falls into the water, it is fished out within five seconds and the phone is turned on. We only need to use a paper towel to absorb the water on its surface, and then use a cotton swab to absorb its charging port, as well as the water in the earpiece, at this time the phone is turned on, we must not touch it, we put it in a ventilated place for two hours.

If the phone does not enter the shutdown state by itself, then we can carefully test all aspects of the phone's functions, and then try to record**, to see if he is hot, if the phone is not hot, it means that there is no water in the phone, and you can use it with confidence.

Solution to heavy water ingress: When our mobile phone is heavily flooded, the mobile phone is turned off or restarts all the time, or the mobile phone obviously feels abnormal. In this case, we must not shake the phone too hard, because if you shake the phone, the water droplets will spread to the CPU, and the phone will not be saved.

In addition, don't put it in this rice, the moisture in the mobile phone can't get out at all, and the dust of the rice will also block the earpiece and the speaker, so that the moisture can't be dissipated, causing your mobile phone parts to corrode, so that your mobile phone is more difficult to repair.

The correct way to deal with it is to gently pick up the phone, if it is automatically shut down, I don't care, if he is not turned off, we need to manually shut down, do not take the initiative to charge, and then according to the above, we wipe the surface water dry, and then we send it to the maintenance master as soon as possible; We don't have the conditions to send the maintenance master, we can use the hair dryer at home to turn on the hot air, and then turn on the minimum wind speed, put it on the mobile phone, bake slowly, bake for at least two hours, and wait for the mobile phone to dry completely, we try to turn it on, if it still can't be turned on, we send it to the maintenance master as soon as possible.

If the phone falls into the water, immediately use a hair dryer to dry it, if it can be turned on normally, it is no problem, if it can't be turned on normally, it is, the motherboard is broken, repair it.

1. Rapid salvage.

If the phone falls into the water, you need to salvage it immediately, wipe it clean with clean toilet paper or cloth, and place the motherboard facing up during the wiping process to avoid a large amount of moisture flowing into the inside of the phone.

2. It is forbidden to turn on the machine.

Although the moisture on the surface of the mobile phone is wiped dry, there is still moisture in the host, and if it is turned on immediately, the motherboard of the mobile phone will be burned, so the mobile phone should not be turned on immediately when it is fished out.

3. Drying treatment.

Turn on the hot and cold air settings alternately on the hair dryer, align the opening of the mobile phone, such as the charging port, headphone jack, SIM card slot, etc., and blow it several times to evaporate the water inside the mobile phone, and then put it into the rice to dry it again.

4. Try to turn it on.

After doing the above steps, you can try to turn on the phone, check whether the buttons of the mobile phone, fingerprint recognition, screen touch, mobile phone speakers, etc. are normal, if normal, you can use it normally, if it is not normal, it needs to be repaired.

Extended information: The best way to dry the phone is to put the phone in a dry rice bag for 24 hours, or even longer, before putting in the rice, the headphone port and the charging socket should be treated with water absorption, and the socket should be taped before putting in the rice, the purpose of this is to prevent broken rice from blocking the headphone jack.

At least you must wait until 24 hours have passed, first of all, to see if every corner of the phone looks dry, and then put the battery in the phone, after looking at the phone, if there is no strange sound, then check the phone to see if it is working properly. If the phone is plugged into the charger and the phone still doesn't work properly, you can only take it for repair.
