What should I do if the Nova 7 falls into the water for half an hour?

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

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.

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 blow with a hair dryer or bake at high temperature 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. The mobile phone is composed of precision electronic components, and there is a hidden risk after water ingress, so please keep the mobile phone turned off.

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

Pick it up and wipe it dry, find a dry place and put it for half an hour to try it and it won't turn it on, otherwise you have to go to a repair shop.

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 the liquid inlet pin is buried, so as to avoid liquid being blown into the phone and damaging the phone at high temperatures.

3.The mobile phone is made of precision electronic components, and there is a potential risk after the liquid is entered, so please keep the mobile phone turned off.

4.If you don't have a backup of your data, you may have 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.

Don't turn on the phone, use a paper towel to blot the surface, the correct way is to first put the opening part of the mobile phone, that is, the place where the mobile phone enters the water, vertically downward, after fixing the mobile phone, use a hair dryer to blow from the non-porous place, to the perforated place, so that you can avoid bringing water droplets to the motherboard, and you can also heat the mobile phone to a certain extent, accelerate the evaporation of internal moisture, but the temperature should be well controlled, and the mobile phone can not be excessively high. In addition, the phone is turned off during the whole process.

If you are ready to repair it immediately, you can fish it out of the water, if there is no condition that can be repaired in time, keep it in the water, the mobile phone is no problem in the water for two days, and it can be repaired in time if you take it out and repair it immediately. If you take it out of the water and wait for a day to repair it, it is estimated that it will not be repaired.

There are several situations in which the phone is flooded, alcohol, drinking water, pond water, sea water, water in the toilet, and oil, and that's pretty much it. With the exception of oil (oil has not been measured), all the water on it will ignite and corrode the circuit board if it comes into contact with the motherboard or battery of a powered phone. There is a protective circuit board in the battery, and when it is short-circuited or the current is too high, it will be powered off, that is, it will no longer output power.

However, there is a lot of water, and the motherboard components will be burned when the fire is fired. The corrosiveness of clean water is relatively small, the corrosiveness of seawater is relatively large, and the dirty water in the toilet is also more corrosive, so it may be that the conductivity of these two types of water is better than that of clean water. Generally, when the mobile phone is flooded, the motherboard is energized, I have done experiments, water is poured on the motherboard that is not energized, just like pouring on the lotus leaf, and it will not mold if it is placed for a period of time (many days).

Therefore, the corrosion of the motherboard is mainly related to the power of the motherboard.

The key is how to deal with it, don't believe the nonsense on the Internet and think that you can do it, just deal with it yourself, blow and blow and dry and so on.

Be sure to remember that pick it up immediately after entering the water, don't shake the water, first dry the water outside with a paper towel, and cut off the power immediately if it can be powered off, for example, if you can remove the battery (many mobile phones used to have a removable battery), remove the battery immediately, if you can't remove the battery, and if you can turn it off, turn it off immediately, (now most smart phones are all-in-one machines, and the battery can't be disassembled by the way). If the phone doesn't respond at the time, don't force it on. Then get a professional mobile phone repair point for the first time, find a really professional maintenance personnel (this is the most important, how to find me and there is no good advice, the current technical level of mobile phone repair practitioners is uneven, with a certain level of professional and technical knowledge of less than 10% of the personnel, it is best to ask word of mouth first, the general professional repair of mobile phone motherboard can be) cleaning and maintenance, do not be stingy with dozens of dollars or even hundreds, leave professional things to professional people to do, don't think about playing smart, the gains outweigh the losses.

Water will corrode the motherboard, even if it dries, it is useless, as long as the motherboard starts to corrode and mold, it will become more and more serious like iron rust. Therefore, it is necessary to clean the motherboard with professional plate washing water, wash the water off, and the cleaned motherboard will not continue to corrode.

What if you can't get the mobile phone repair point right away, if you are outside, wipe the outside first, turn off the power or turn off, get the repair point as soon as possible, if it is night, the mobile phone repair point is generally off work, the method is the same, you can consider blowing it with a hair dryer.

In short, if the mobile phone enters the water, the power will be cut off or shut down immediately, and the nearest professional maintenance personnel will be found immediately for cleaning or repair, so as to minimize the loss as much as possible, and leave the professional things to the professional people.

It is recommended that you take it to the maintenance point and disassemble it, and then check it to see if there is any fault after drying the internal moisture, and then start it normally after eliminating the fault.

Take it out of the water, use all the tools that can suck the phone dry, quickly blot it dry, don't press the power on in the middle, wait until the phone is completely dry, and then try to turn it on, if it can't be turned on, it may burn out.

Don't turn it on, take it apart from the maintenance point immediately, dry it with a hot blower, and let the maintenance master deal with it.
