What should I do if there is water and no network signal in the screen of the mobile phone?

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.

1: No matter what kind of water the phone falls into, you should directly remove the phone battery (instead of pressing the power off button) as soon as possible!

2: Use undusted napkins, cotton balls, cotton swabs, etc. to absorb all the water that can be wiped off outside.

3: If it falls into clean water, you can clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together (provided that you have anhydrous alcohol). If it falls into the sewage, it should be cleaned immediately, and the visible dirt should be cleaned first, and the impurities attached to the components should be brushed off with a brush.

4: Use a hair dryer to swing the dryer from a distance. (Be careful not to blow too close or to one place for a long time).

5: Keep the phone in a cool and dry place for 24 hours, if there is no hair dryer to dry the water, it is best to leave it for 48 hours.

6: Install a battery with sufficient power to test it, if it can't be turned on, then you have to take it for maintenance. Good luck to the landlord!

It's not going to be a resurgence, is it? There is water mist in the screen, under normal circumstances, it can be blown with a hair dryer and hot air, as for no signal, it's not a fog problem, take it to the maintenance point to see it, girl, it's generally a trivial matter, and it's very cheap to repair.

What machine, you don't want to spend money, just take it to the sun, it is recommended to take it to the mobile phone store and let the professional master wash the motherboard for you, so as not to make problems in the future

Just dry it with a hair dryer.

Blow at it with a hair dryer, I've done you try it.

<>1. First of all, the slag mobile phone cannot be turned on immediately after falling into the water and picking it up.

2. However, how long has it been in the water, at this time, the motherboard may have been dismantled, so use the hot air shield of the hair dryer to evaporate the water.

3. The hot air gear can not blow for too long, stop blowing for 5 minutes, blow quietly after a few minutes, and then let the phone cool for a few hours, so that the water in the motherboard of the mobile phone can evaporate, and you can put it in the sun for a while.

4. After the cool sun, you can shake it to see if there is any moisture thrown out, if not, you can try to restart, you can turn it on, if you can't open it, you can only send it for repair.

5. If there is no signal on the mobile phone card after booting, you can pull out the card.

6. Send the mobile phone to clean and wipe, if not, you can put it on the clothes to wipe it, and put the mobile phone into it.

7. If it still doesn't work, it can only be sent for repair, and it may be hardware damage.
