Generally, replacing the charger can solve the problem 90% of the time. If you unplug the charger, or even start it again, it still flashes and jumps, and it basically has to be repaired, either to change the screen or change the chip.

2. The local voltage is unstable.

3. Poor contact with the power supply.

Hello, I'm glad to reply to you, the reasons and treatment methods for the flashing screen when charging: 1. The disadvantages of the capacitive screen of the mobile phone, the capacitive screen will be affected by the current when charging, so sometimes there will be a phenomenon of jumping by itself, which is normal Now, unplug the imitation mobile phone from the charger to solve this problem. 2. The relationship between the water ingress of the mobile phone, due to the internal moisture of the mobile phone and other reasons, the current in the mobile phone is unstable, and this phenomenon will also occur, you can try to dry the mobile phone under the hair dryer, or you can put the mobile phone in a sealed jar full of rice, and the rice will absorb the moisture in the mobile phone.

3. The fault of the mobile phone system, if the above two methods can not be solved, then you can try to restore the factory settings, if it still doesn't work, you can use the way of flashing, but it is best to get a professional repair shop, please ask a professional to test and repair better. I hope it will be helpful to you, and if you have any other questions in the future, you can feel free to find a teacher. I wish you all the best in your life.

The reasons why the phone can't be charged in a flashing flash and its solutions are as follows:

1. The first reason is that the interface is poor, and you can use a cotton swab to wipe off the dust, clean it, and ensure smooth power-on.

2. The second reason is that the data cable of the charger and the tail plug of the mobile phone are in poor contact, and it can be restored to normal by replacing a good data cable.

3. The third reason is that the charger does not match the mobile phone, for example, some support the fast charging bridge, and some do not, so you can update the charger.

Detailed Ways to Charge Your New Phone Properly:

1. The new mobile phone battery should be used to the low power alarm of 10%-20% in the first three times, and then the original direct charge will be used to charge the mobile phone to a full capacity, and then continue to charge for about 1 hour.

2. In daily use, the battery is fully charged, to avoid continuing to charge for a long time, the remaining power of the mobile phone can be charged at 20%-30%, no need to use a low power warning, in case of shutdown, the battery should be charged as soon as possible.

3. Try to avoid charging before going to bed, because the charging time before going to bed is longer, and the voltage is unstable at night, and the night voltage in many places is relatively high and fluctuates greatly, which has a greater impact on the battery.

4. The battery of the general mobile phone can be charged, used and stopped at any time. Cycle life refers to the number of full charge and full discharge, and partial charge and discharge can be understood as a fraction of the life of the sensitive rent. The key to battery use:

The battery is fully charged, and it can be charged for 20 minutes to half an hour to reach saturation, but be sure to avoid charging it for a long time after it is fully charged.

Note: The mobile phone or charger with lithium battery will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours with a nickel electric charger. That is to say, if your lithium battery is fully charged, it will also be white charged when placed on the charger.

And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality is foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long charging. <>

The charging equipment itself has serious contact quality problems;

When charging, when the screen is touched, the potential of the display screen changes, and the current input during charging is abnormal;

Conventional charging must use the original ** mobile phone charging equipment, the voltage carried by different mobile phone charging equipment is tested and tested, it is best not to borrow the charging equipment of colleagues and friends casually;

Try not to use the mobile phone in the process of charging, and the frequent use of the mobile phone in the charging state is easy to shorten the service life of the mobile phone battery, which will cause electric shock;
