The phone fell into the water, why are there a few keys that can t be pressed?

Summary. Will the phone drop in the water cause the keys to freeze?

Well, if your phone falls into the water, if your phone has a waterproof function, then entering the water in a short period of time will not cause any impact on the phone.

Second, if your mobile phone does not have the function of waterproof shelter, it will enter the water in a short time. As long as you carry out reasonable air drying, and do not carry out other operations and dangerous operations such as charging when the phone is not completely air-dried, your mobile phone will not collapse into any effect.

If your phone is in water for too long, it may affect the internal circuit of your hand cleaner. This effect can directly impair the normal operation of the phone. He Hu Li does not refer to the function that you press the keys to freeze, it is to make the first many functions of the hail do not work properly.

If you are appearing, just the keys are stuck, it may be that your phone's memory makes it possible to use too many movies to delete without a simple memory, then your phone will no longer be stuck.

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 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.

Disassemble and remove the battery immediately, wipe it dry with water, and blow dry, the sooner the better.

If you can't do it yourself, you can remove the battery first and go to the repair department to deal with it.

The first thing to do is that water ingress and crashing are the two taboos of mobile phone use, and the 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 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.

Turn off the machine, cut off the power, dry, and then turn it on in two days, if it doesn't work, change the machine.

Here are 5 ways to do this:

1. Open the back cover and dry it in a ventilated place reliably, but it takes a long time to return to the room.

2. Drying in the sun is relatively fast, but there may be other problems due to high temperature, and there may be water vapor.

3. Dry with a hair dryer, but water vapor may also remain.

4. Use 5 to 6 small packets of desiccant, wrap the mobile phone with some thin paper towels, generally 24 hours can be turned on with confidence, the time is fast, and the effect is good, but it is necessary to pay attention to prevent the desiccant from entering the mobile phone.

5. After drying the water as much as possible, you can remove the battery of the mobile phone and put it in the baking machine, and bake it below 40 degrees Celsius for about 15 minutes.

After the mobile phone falls into water, it turns on normally, but the touch screen cannot be used, indicating that the relevant parts of the mobile phone screen are damaged by water, and it is recommended to overhaul it.

There are two main situations in which water ingress into mobile phones:

1.If the mobile phone penetrates into clean water, it will generally cause the mobile phone components to be short-circuited and burned when exposed to water.

2.The mobile phone is infiltrated with corrosive liquids such as salt water and alkaline water, which will corrode the motherboard components.

The loss caused by this is irreparable, and can generally only be solved by replacing the motherboard, which is costly, and the user needs to bear the relevant costs.

Generally speaking, after the water enters, the battery should be deducted immediately, if it is a built-in battery, you can press and hold the power button to shut down urgently, and then put it in a ventilated and warm place to dry, if you have the ability, it is recommended to immediately disassemble the machine to clean up the liquid that enters, and then turn on the test after ten hours of thorough drying.

Blow it with a hair dryer for a few minutes, then put it in a dry and ventilated place for a day, and then turn it on again at night. Try to dry it with a hot blower, you can blow it for a while.

Take out the battery, dry it with a hair dryer until there is no fog, and turn it on to see if it works. In fact, it is best to go directly to the repair shop to wash and dry. I'm afraid that you will burn the mobile phone board if you don't operate it properly.

Dry it, or disassemble it and wipe it. Not yet, either spend money to repair it or throw it away.

Don't let it out into the sun.
