This waterproof refers to general waterproofing, and it is even more difficult to say if it falls into the water.

See how long and how deep.

It is not determined where the water will be forced.

Most of the current waterproofing is life waterproofing.

Huawei Mate30 is dust and water resistant, and its protection level is IP53. However, the Mate30 mobile phone is not a professional waterproof mobile phone, and it can be splash-proof, water-resistant, and dust-proof under normal use, and the splash-proof, water-resistant, and dust-proof functions are not permanently effective, and the protective performance may be reduced due to daily wear and tear.

Huawei Mate30 is a smartphone developed by Huawei, using Kirin 990 processor, running memory 6GB 8GB, body memory 128GB 256GB, built-in 4200mAh battery, pre-installed EMUI10 system, screen fingerprint recognition, IP53 waterproof, rear super sensitive Leica triple camera, 3x optical zoom, 5x hybrid zoom, 30x digital zoom.

After the phone falls into the water, you should follow the following methods.

1. What is the first thing to do after the phone falls into the water? Of course, the phone is fished out of the water, this matter is very important, the longer the phone is soaked in water, the greater the damage to the phone's earpiece, buttons, screen and motherboard, so the phone should be fished out of the water as soon as it falls into the water.

2. After the mobile phone is fished out of the water, first wipe the water stains on the surface with a paper towel, but don't turn it on, don't turn it on, don't turn it on, say important things a few times, many friends will first see if the phone can be turned on, this practice is extremely wrong, because the water is not cleaned up, and the motherboard will be burned if the power is connected again, so don't turn it on.

3. The first thing we have to do after the mobile phone is fished out is to take out the battery first, regardless of whether the mobile phone is turned on or off before entering the water, the battery should be removed immediately, but now many mobile phones are all-in-one machines, it is difficult to take out non-professional personnel, if you have no experience, do not easily disassemble the phone, to avoid secondary damage.

4. The water in the mobile phone is almost shaken off, don't be in a hurry to turn it on, use a hair dryer to maintain the temperature that is not hot, blow on the place where the mobile phone has holes, decide the number and time of blowing according to the degree of water entry, and then start to dry it.

5. The drying treatment of mobile phones generally uses desiccant and drying box, most families may not have these things, but there will also be small bags of desiccant in the snacks we usually buy, and we can usually collect some in case of emergency.

6. The dried mobile phone can be turned on, if it still can't be turned on at this time, you need to go to the repair shop to ask for help.

You really have to go through everything, just like today's incident of slipping your hand and dropping your phone into the water.

Fortunately, it was saved in time, and I also listened to some so-called "tricks" in the process, but looking back, it was simply a secondary injury, but fortunately, the secondary damage I carried out was not big, otherwise I would really feel distressed.

What should I do if my phone falls out of water?

First, get out of the water right away!

Second, shut down! In the process, even if the alarm is turned on by the original setting, do not call**!! Shut down again!!

Third, don't use a hair dryer to practice the so-called blow drying, maybe you have friends around you who use a hair dryer to dry their mobile phones when they fall into the water, but that's someone's mobile phone, not yours! Because, blowing with a hair dryer is likely to blow the water deeper inside, which is more likely to hurt the phone.

Fourth, go to the official website as soon as possible to check the nearby service center, don't believe the web page to launch those, go to the official website, regular, guaranteed!

Fifth, after arriving at the service center, try to describe the process in detail, and tell the other party how to rescue the mobile phone.

Finally, be patient.

Hopefully we can all wait for a good result!

First, take it out and blot the water with toilet paper, then dry it with a hair dryer and send it to Huawei's after-sales service center for repair, which can be repaired in three days.

Hello, Huawei Mate 30 is waterproof and dustproof (IP53).

The waterproof and dustproof ability of the mobile phone is usually marked by IPXX, and the xx at the back represents the different types of dustproof and waterproof, accompanied by different numbers to show different protection capabilities. The first number indicates the level of dust and foreign intrusion of the electrical appliance, and the second number indicates the airtightness of the electrical appliance against moisture and water intrusion, and the higher the number, the higher the protection level. Different products have different levels of IP protection.

IP53 has a dust protection level of 5, which means that it is not completely dustproof, but dust will not cause damage to the equipment or accumulate in a large area; The waterproof level is level 3, which can prevent rain or water sprayed in the direction of less than 60 degrees from the vertical angle from invading the appliance and causing damage.

1. Turn off the phone and take out the card inside the phone to check whether there are water stains on the card slot, because the card slot is close to the motherboard of the mobile phone, if there is no water on the card slot, it means that the motherboard of the mobile phone has not yet entered the water. Then the mobile phone is relatively safe and saved, and generally at this time, only the headphone jack and earpiece are flooded. So how to check if this place is flooded?

In fact, before turning off the phone, you can judge it by the display in the upper right corner of the phone.

Second, if the headphone hole is flooded, the upper right corner will display a logo inserted into the headset like this, you have to put the mobile phone hole control downward, shake it hard, the mobile phone can throw out most of the water stains, and throw it out until there are no obvious water stains, then now there is some moisture and water vapor left in our mobile phone. We are moving on to the next step, because most of the water stains in the previous mobile phone have been thrown out, and then take out the hair dryer at home to blow the earpiece and headphone jack of our mobile phone alternately to dry the little water left inside. But don't be in a hurry to turn it on.

If you have a suction nozzle at home, you can use it to suck our earpiece hole, this is very easy to use, it can suck out all the impurities inside, if not, you can tear off the cotton on the cotton swab and wrap it a little bit around the toothpick, use the tip of the toothpick to plug in the mobile phone earpiece and the earphone jack to try it, in case the water inside is not blown dry, you can also wipe the water stains inside, which is equivalent to cleaning up the headphone hole.

Third, wipe all clean, normal is to turn on, but in order to be safe, we also need to bury the mobile phone into the rice and cover the mobile phone with rice, because the rice is very dry, and the rice has strong adsorption, just bury the mobile phone in the rice overnight, in case the mobile phone is more serious, so that the rice can be used to absorb all the water of the mobile phone. Double insurance: Many people are in a hurry to turn on the phone, and the internal water is not clean, resulting in the black screen of the mobile phone and cannot be opened. The phone can be turned on normally after magnifying Miri overnight, and the phone can be restored to normal at this time.

This means that the phone is back to normal. Although it seems like a lot of steps, the effect is very good.

Fourth, there is no sound from the mobile phone earpiece, it must be a short circuit caused by water ingress, you can take it to the mobile phone repair shop, and let him help you clean it up.

Hello to the subject, this question is very simple, find the staff near the water, there are generally copying nets, try to fish, you are lucky, you can't buy a new one.

If there is no sound from the earphones, you can use a cotton swab or paper towel to clean up the water in the earphone hole.

Then rule out whether the volume is too low, and you may need to replace the speaker after all of the above are ruled out. Here's a closer look:

What should I do if my phone stops sound after falling into the water?
