If there are traces left on the display of the mobile phone screen, there are two cases. The first case is that your mobile phone has bumped and damaged the mobile phone screen. The second case is that your mobile phone screen displays the same text and pictures for a long time, causing some screens to burn, and the screen materials aging faster than other places. The mobile phone screen needs to be replaced. Most of the smart phones we use now are capacitive screens, which use touch control to control mobile phones.If the screen of our mobile phone fails, it will become a "brick". It can be said that almost everything on the mobile phone can not be done.There are many reasons for the failure of the mobile phone screen. For example, there is static electricity, dust on the surface of the mobile phone screen, and excessive sweating on the hands.Mobile phone screen failure will bring us great inconvenience.What should we do then?Today, I will talk about four ways to deal with the failure of mobile phone screen.
The first case: mobile phone crash or pseudo crash caused by software
Sometimes when we use the APP on the phone, the phone suddenly seems to crash after opening it. The screen is stuck and can't move. How to touch the screen does not respond.This is only a temporary failure of the mobile phone, mainly because there are too many background apps leading to insufficient memory of the mobile phone, and the mobile phone needs more time to respond.At this time, we just need to open the task manager, that is, open the background interface (each mobile phone has a different operation method), and turn off some APPs in the background.Sometimes, if this doesn't work, we just press the power button and restart the phone.If your phone has a HOME key, you can also press and hold the "HOME key+power key" to force the phone to restart.Generally, it can solve the problem of unable to touch the phone caused by this situation.
The second case: screen failure caused by static electricity
Many friends may have had the experience that after the phone is taken out of the pocket or bag, they find how to move the screen, but they do not respond to the touch of the screen.If a phone call comes in at this time, you will be very worried.This is actually because the mobile phone has friction in a dry environment such as the pocket or bag, or is affected by some other electromagnetic fields, resulting in the temporary failure of the screen.What shall we do at this time?You can wipe the screen with your palm in one direction for a few times, which can remove static electricity to a large extent.If this doesn't work, you can also use a little wet cloth to wipe the screen, because water can take away static electricity.Of course, another method is to use transparent tape. When the tape is opened, some static electricity can be taken away.
The third case: failure caused by missing or damaged system files
When Android phones root, some changes and deletions will be made to the system files in the phones, sometimes resulting in screen failure.In addition, in the process of system upgrade, sudden interruption caused by network or power failure can easily damage system files and also cause screen failure.At this time, we need to clean or reset the mobile phone. If possible, we must backup our important data when cleaning the mobile phone.Although most of the current machines are very simple, if you are a friend who has not operated the machine, it is recommended that you ask a friend who can brush the machine to help you operate it.
The fourth case: screen failure caused by hardware damage
After the mobile phone falls or enters the water, it is easy to damage the LCD screen cable and touch IC. The damage of the hardware type will cause problems such as screen failure and "drift".The best way to deal with this situation is to give it to a professional for repair, such as after sales of your mobile phone or make an appointment with a professional engineer of your mobile phone brand to test and repair your mobile phone.
Finally, I would like to remind you that there are 6 weaknesses in the mobile phone screen. You should pay attention to the following situations when using mobile phones.
1. Fear of static electricity 2. Fear of oil stains and stains 3. Fear of high temperature 4. Fear of electric waves and magnetic fields 5. Fear of unstable voltage 6. Fear of extrusion
Do you think your mobile phone screen is very fragile after reading it? Although these methods can solve the problem of mobile phone screen failure to some extent.But I suggest that you should take good care of your mobile phones.
The same text or picture is displayed at the same position of the screen for a long time, and the display material at that position is aging more than other parts, or the aging brightness of the light source here is lower than other parts.Due to the characteristics of the led screen, it is better to use dynamic wallpaper instead of staying on the same interface "Burning the screen" does not mean that the plasma screen will burn out, but that after the same picture is displayed on the screen for a long time (such as a still picture or the logo of a TV station), the residual image of the picture will be permanently left on the screen.Therefore, in the process of use, avoid playing the same picture for a long time. If you look at it or in a certain environment, LCD and picture tube can burn the screen, but there is no display without burning the screen. Only the phenomenon of burning the screen is common in plasma, but there is no permanent burning of the plasma panel now. Or the probability of permanent burning the screen is extremely low. Basically, there will be only residual images(That is, the bureau is still in a picture with high brightness and sharpness contrast for a long time) A faint shadow will be seen after power off or when the screen is black.) However, as long as you switch to the dynamic picture and put it on for a few seconds, the shadow will disappear (the shadow can only be vaguely seen after pure black gray and power off). It is reversible
My Huawei P40PrO is the same, and it is also the slogan of the product. But this is not the case with the Mate9 I bought before. The 5988 has a domestic screen and the sound quality is super junk. This is definitely my last Huawei mobile phone, and I will never listen to the online water army again
