What should I do if my phone falls into the water, and what should I do if my phone falls into the w

Mobile phone water treatment method:

1.Shut down immediately.

If the phone falls into the water, you need to salvage the phone immediately, and quickly press the power off button to turn it off, if it is a detachable phone, then we can take out the battery, memory card, etc. first. Powering off your phone first will prevent your phone's battery from being short-circuited**. If the phone is dropped vertically, it is best to pick it up vertically.

2.Remove moisture.

After the phone is scooped up. You need to wipe the surface of the phone with a clean towel and other items first, and then wipe the earphone jack and other parts with a thin cotton swab. Do not shake your phone dry too hard, as this may allow water from the surface of the phone to seep deeper into the area.

3.Blow dry with a hair dryer.

For the moisture inside the phone, we can use a hair dryer to dry it. Do not use hot air in the process of using the hair dryer, the hair dryer and the mobile phone need to keep a certain distance, it is best to let the wind blown out of it close to the normal temperature, do not direct the air outlet of the hair dryer to the mobile phone, usually the hair dryer blows the mobile phone for about 20 minutes.

Water ingress and crashing are the two major taboos in the use of mobile phones, and water ingress of mobile phones is particularly serious. According to an engineer from Guoxin, after the mobile phone gets into the water, the first thing to do is to turn off the power, of course, not to press the shutdown button, but to remove the battery. Because as soon as you press the shutdown button, the mobile phone will be powered on, and it is likely that a short circuit will occur, causing damage to the mobile phone, and then send it for repair as soon as possible.

If your phone's warranty has expired and you don't want to send it for repair, you can boldly take it apart! Wipe the parts of the phone with a tissue, and then blow it with a hair dryer for a few minutes, in order to ensure that all the internal parts are dry, it is advisable to air dry the phone for a few more days before you can turn it on again.

Once the mobile phone gets into the water, the battery should be removed immediately, and it must not be turned on immediately to understand the condition of the mobile phone. After removing the battery, do not use a hair dryer to deal with it, and immediately send it to the repair professional to disassemble the machine for water treatment, such as falling into sewage or corrosive liquid, and use ultrasonic cleaning and drying before proceeding to the next step of maintenance. If the mobile phone can still be used after water penetration, it should be sent to a professional to deal with it to avoid corrosion of the circuit board and make it impossible to repair.

No matter what kind of water the phone falls into, you should first remove the phone battery and no longer power the phone. If it falls into clean water, remove the battery and clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together. Then use a heat gun or hair dryer to dry the circuit board, and then power up the test machine, and most mobile phones will work normally.

If it falls into the sewage, it should be cleaned immediately, and the dirt that can be seen should be cleaned first. Use a brush to brush off the impurities attached to the pins of the components. Then, the circuit board is scrubbed with an alcohol cotton ball, and if the pollution is serious, the impurities must be vibrated out with the help of an ultrasonic washing instrument.

Then use an air gun to dry the circuit board, and then repair all the chips.

First of all, we score the situation, mainly as follows: falling into clear water when the power is on; Falling into non-corrosive liquids in the event of a power failure; Falling into non-clean water when the power is on, or falling into corrosive liquids or liquids or other clean liquids regardless of whether the power is applied or not. <>

The first two cases have a good chance of being saved and there may be no sequelae, while the latter depends on luck. Of course, if you are unlucky, PPC will also be bad if you put it in your pocket. The biggest problem after PPC water ingress is how to deal with it.

First of all, for the 1st and 2nd cases, we must not think that the machine has been scrapped. Don't think it's already in the water anyway, so you disassemble it indiscriminately.

For the first situation: falling into clean water when the power is on, this situation generally does not need to be disassembled.

1 Power off as soon as possible.

2 Shake it dry, but don't shake the machine off, the idea is to shake the water out of the screen. If there are water droplets left on the screen, there will be traces after drying.

3 Place under a slight heat source such as a desk lamp or spotlight to let the moisture slowly dissipate. This process takes more than six hours. If you use a hair dryer, it is recommended to use the natural cool breeze of the hair dryer and try not to use very hot wind.

After these three steps of processing, the power supply can basically work normally.

For the second condition: falling into a non-corrosive liquid in the event of a power failure. In this case, it can be assumed that the machine is not damaged. But maybe the LCD screen will be more ugly.

1 Shake dry vigorously, but don't shake the machine off.

2 If there is no trace on the LCD screen, treat it according to Article 3 of the first point.

3 If there is something left on the screen and it is very serious, do not deal with it according to point 1, paragraph 3, because although the electronic circuit can work normally, the screen may be quite ugly. It can be sent to the nearest maintenance department for processing or dismantling the machine for cleaning by yourself.

For the third condition: falling into non-clean water when the power is on, or falling into corrosive liquid or viscous liquid or other clean liquid regardless of whether the power is on or not.

This situation is the most troublesome. However, there is also a good chance that the machine will recover after proper treatment.

1 Power off as soon as possible.

2 If it falls into corrosive liquid (e.g. seawater), rinse the machine with clean water immediately. Or immerse the machine in clean water and try to dilute the corrosive liquid inside.

3 Disassemble the machine as soon as possible. But take your time when disassembling the machine.

4 Clean with alcohol or professional washing water.

5 Assemble. Or take the whole pile of what you took apart and hand it over to the repair point. Let the repair point clean and assemble it again for you.

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 use a hair dryer to blow or bake at high temperature (including microwave heating) 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 potential 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.

After scooping it out of the water, immediately wipe the surface of the phone dry with a dry paper towel, rag or even clothes, take out the SIM card slot, and use a paper towel to absorb water at each opening of the phone. Remember, don't press buttons such as the power button and volume button, don't turn on, don't turn on, don't turn on, this is the most important point, because once turned on, due to the water in the body, connecting the power again will cause the motherboard to burn out.

After the mobile phone falls into the water, it is best not to blow it with a hair dryer, because the hair dryer blowing is, it will cause the moisture inside the mobile phone to move, which may cause greater damage to the mobile phone, and if it is blown with hot air, it will have a certain impact on the mobile phone screen.

The best way is to go to the repair shop to disassemble and dry [smile] [compare heart] [compare heart].

Answer: The mobile phone should be fished out immediately if it falls in the water, get rid of the water in time, turn it off immediately, and put the mobile phone in the middle of the rice, because the rice has the effect of absorbing water, so after 24 hours of isolation, take out the mobile phone and turn it on.

If the phone falls into the water, you should immediately take the phone out, then wipe it clean with a clean cloth or paper, wipe the external surface, and then turn it off and put it in a ventilated place for ventilation, and then go to the after-sales service.

If the phone is not waterproof, it should be turned off directly after taking it out of the water. If you can open the back cover, it is best to unplug the battery cord to prevent short circuit. To observe the water intake of your mobile phone, consider using a hair dryer or something like newspaper to wrap the water in the steam.

Sometimes if it's light, it's okay to dry it for two days

It should be turned off in time, immediately blow it with a hair dryer, so that the water inside evaporates, and then turn on the machine after the water in it evaporates, if it doesn't work, take it for maintenance.

Take it out quickly to control the water and dry, and don't turn it on immediately.

If you use an OPPO phone after water or liquid ingress, in order to avoid further damage, it is recommended to deal with it according to the following methods:

1.Judge the power on and off status of the mobile phone, if the mobile phone is turned on, please turn it off immediately, if the mobile phone is turned off, please do not try to turn it on;

2.Take out the SIM card and memory card of the mobile phone in time, and remove the battery if the mobile phone is a removable battery;

3.Use a paper towel or cotton swab to dry water stains on the surface of the mobile phone;

4.If it is not cleaned after liquid ingress, it will accelerate the oxidation and damage of the internal components of the mobile phone, so it is recommended to send it to the customer service center for testing and repair as soon as possible.

Notes:1Please do not turn on or charge the phone after water ingress, at this time, powering may cause short circuit damage to the components of the mobile phone;

2.Please do not try to shake off the moisture by shaking the phone, this operation may cause the liquid to seep into other components;

3.Please do not use a hair dryer or oven to bake your phone, as high temperature and high heat may cause permanent damage to the components of the mobile phone (after the moisture inside the mobile phone is heated into water vapor by a hair dryer, etc., it may penetrate into other components of the screen, which will cause the mobile phone to get wet and damage the electronic components).
