There is water in the screen of the mobile phone, and the water will move if you press it with your

Yours shouldn't be a fully bonded screen, it is recommended to change the screen, the touch screen is useless.

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.

OneAbout the aboveThe phone is flooded, the upper part of the screen can't be used, and the bottom can be controlled, and the screen as a whole is a little out of order

The above problem is caused by water ingress into the mobile phoneScreen touch local failure,This shows that the basic working conditions of the touch circuit have been partial, but not fully working, therefore, for the problem of local failure of touch, after eliminating the problem of display components, it is necessary to focus on checking the touch interface to see if the touch interface has a virtual soldering problem(Use a digital multimeter to measure the resistance value of the touch interface to the ground, and compare it with the resistance value of a normal mobile phone to find the abnormal point).

If the phone gets into the water, please don't turn it on, put the phone in a cool place, let it dry naturally, and then check the relevant screen, if the screen is really problematic, then just replace the screen.

Most of them are mobile phones with capacitive screens, and capacitive screens use the current induction of the human body to work.

When the user touches the screen, due to the electric field of the human body, the user and the surface of the touch screen will form a coupling capacitor, for high-frequency current, the capacitor is a direct conductor, so the finger will suck a small current from the contact point. This current divides from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance of the finger to the four corners, and the controller derives the position of the touch point by accurately calculating the proportion of these four currents.

To put it simply, where the user touches, there will be "leakage", and the screen will react. When the screen is wet with water, because of the conductive nature of water, when the water touches the screen, the current will be affected when you touch it with your hand, so the above calculation is not accurate, which is also called screen drift.

Of course, not all capacitive screen mobile phones are afraid of water shower, generally speaking, capacitive screens are divided into two kinds, one is self-capacitance, the other is mutual capacitance, relatively speaking, the algorithm of self-capacitance is easy to deal with this kind of problem (simply put, it automatically ignores the capacitance brought by water), and the resistance will be stronger. However, self-capacitance can only be done as a virtual two points, and now mobile phones are at least 5 points of mutual capacitance, for mutual capacitance, the contact response generally does not include the reference of signal strength value, and the problem of water droplets will be more obvious.

Nowadays, mobile phones that can be operated with water are basically enhanced signal processing accuracy and use higher refresh rates to make them able to distinguish small signal changes. In this way, even if the conductive surface is formed with water, a small signal difference will still be formed in the position of the finger when the hand is clicked, so as to determine the touch position.

The screen of the mobile phone will fail when it is wet, indicating that the touch sensitivity of the mobile phone has been reduced, so if you touch the mobile phone with water, they will fail.

The phone screen will not fail if it is wet, sometimes you can use your hand to tap into the water, you can wipe it with a dry cloth.

It is recommended not to turn on the machine first, so as not to break the others, immediately go to the repair shop to change the touch screen, change the touch screen is only a few hundred yuan, if the others are also broken, maybe it is better to buy a new one, I hope it will help you.

It should be water or water mist into the screen, it is recommended to remove the battery directly, put it in a ventilated place overnight or for a few days, according to the water ingress, do not use a hair dryer.

It may be that the screen is flooded, which affects the sensitivity.

If the mobile phone falls into the water, it can be turned on, but the touch screen does not respond, it may be that the screen is in water, and it should be sent to the maintenance point for maintenance, don't fool yourself.

If the mobile phone falls into the water, it is not recommended to turn it on immediately, if the water is serious, the mobile phone will burn. In your case, it may be that the screen has some water, so it affects the use, try to turn off the computer first, bask in the sun for a while, or use a hair dryer to blow hot air.

If the screen is flooded, don't use a hair dryer to blow it.

If you are using a vivo mobile phone, the liquid inlet treatment method of the mobile phone:

1. Shut down immediately and take out the SIM card and SD card; Do not force it on, it is very likely to cause a short circuit.

2. Lay the socks flat on the body, use paper towels or soft cloths to absorb water, and try to absorb the water in the gaps; Try not to move your phone when sucking in the water.

3. Do not attempt to charge; Don't shake your phone too hard; Do not heat your phone.

4. Stand in a ventilated and dry place, and place it with the screen facing up and the front camera tilting upward;

5. Bring your mobile phone to the vivo customer service center as soon as possible and let the maintenance engineer conduct professional testing.

Customer service center address: enter the vivo official website vivo**app--my--service outlets after-sales outlets--select provinces and cities to inquire about the address of the customer service center) It is recommended to call the customer service center in advance to confirm relevant matters and understand the working time, so as not to delay valuable time.

In this case, you should quickly find a professional to disassemble the machine and remove the battery, drain it, and dry it to avoid the expansion of the failure.

Blow the water dry, if it doesn't work, change the screen, and treat the motherboard to prevent corrosion of the motherboard.

If you are using a vivo mobile phone, bring the mobile phone to the vivo customer service center as soon as possible and let the maintenance engineer conduct a professional inspection.

Customer service center address: enter the vivo official website vivo**app--my--service outlets after-sales outlets--select provinces and cities to inquire about the customer service center, it is recommended to call the customer service center in advance to confirm the relevant matters and understand the working time to go, so as not to delay valuable time.

It may be that the motherboard touch circuit is not working properly, or try changing the screen.
