The phone suddenly went black with snowflakes on it, what s going on

The black screen of the mobile phone is one of the faults that are often encountered in the maintenance of mobile phones, and the black screen can be divided into two types: one is the black screen in use, and the other is the black screen in standby.

Most of the black screens in use are caused by their own third-party software, and this situation rarely occurs with the machine. It can also be subdivided into two kinds: one is that there is a problem with the software itself, the software itself is unstable, or it does not match the mobile phone system, etc., this is easy to solve, just uninstall it; The second is the conflict between the software and the software, which is a little more troublesome to solve, and requires a software to install and uninstall the software in the experiment.

If you find it, uninstall it, and the problem will basically be solved.

It is recommended not to install too much useless chicken rib software. Although buying a smartphone is to play the machine. But some software that you don't use at all is a waste.

As for the black screen in standby, most of the straight board machines have a power-saving circuit design: the mobile phone will automatically turn off the screen if it can't detect the key trigger signal for a long time, that is, standby, when you need to use the mobile phone, a button will activate the power-saving circuit, and then the screen lights up!

The reason for the black screen is often reflected by the delay of the screen triggering circuit. That is to say, the mobile phone system has issued a command to light up the screen, but because the circuit is delayed, it is not sent successfully, and the screen is not lit successfully, but the mobile phone system thinks it has been lit, so it causes a black screen.

The phone screen is black, don't be in a hurry to restore it first. Use a friend's mobile phone to call your own **, if you can get through, you can also answer normally. That's basically the problem.

There is no need to panic when a black screen appears, and there is no need to pick the battery immediately. You can leave the phone for about 3 minutes without pressing any keys on the phone, and then press the button again to activate the screen. After many years of practice.

It can generally be returned to normal immediately! In this way, it basically does not have a big impact on the use.

Was this the case before?

This may be caused by the interference of electrical appliances around you, if you have a speaker and other electrical appliances placed next to the main unit, it is easy to interfere with the display. Try turning off these appliances first and see if the snowflakes go away.

Hello, the phone becomes a black screen after the snowflake screen is turned on, and the iPhone itself is unstable, resulting in a black screen. This kind of black screen can be attributed to an unstable automatic shutdown, which is because the machine is of poor quality, resulting in shutdown for no reason. Since there is no big problem with the return of hardware, you can just press and hold the power button and wait for it to turn on.

The second scenario. DFU mode is the mode in which the Apple system cannot be turned on if there is a problem, while entering the recovery mode can be recovered with iTunes. But the phone is fine, and it can't be turned on because it can't be turned on because it has entered DFU mode by mistake, but it's actually very easy to solve.

You only need to press and hold the power button at the same time and wait for the iPhone to react, generally 10 seconds, if there is no response for tens of seconds, the following steps continue. In the third case, you need to enter DFU mode, first of all, iTunes must be installed on the computer, and you can ** a new iOS system. Or you can restore files with a backup line in advance.

The snowflake screen is because the motherboard and the screen are combined too tightly, and there is a layer of oil inside the touchscreen mobile phone, and if the bonding is too tight, the oil will be squeezed out of the screen.

Restart the phone, the screen still changes color, not the normal color, check the system-related color settings. Find the settings on the desktop of the phone, enter the accessibility function, if there is a category, select Vision, find the negative color in the vision, and see if this item is checked. The color of the screen of electronic products is composed of three primary colors: red, green and blue, which is the positive color.

As for the negative color, the negative color is based on the positive color, and the white light is filtered and printed.

The display cable is the first signal transmission line between the motherboard display IC and the display screen, and the display cable is soldered or loose, which will also cause the mobile phone screen to change color or appear vertical, which is common in the mobile phone has been dropped, especially the chain bridge mobile phone has been disassembled. The mobile phone screen is a fully bonded integrated screen, which is composed of an outer screen glass, a touch screen and an LCD screen.

Mobile phone screen maintenance:

When choosing a mobile phone screen protector, you should carefully consider the parameters involved, such as quality, transparency, thickness, fit, etc. In addition, it is important to check whether the protective film has antibacterial function, which can reduce the breeding of viruses and dust on the mobile phone screen.

Also, pay attention to the softness and friction resistance of your phone screen protector. If the softness of the protective film is not enough, it is easy to cause the surface of the mobile phone screen to be scratched. Friction resistance is also very important, because if the friction resistance of the protective film is too poor, the surface of the mobile phone screen will become more susceptible to damage.

Phone Black Screen of Death Solution:

Crash due to insufficient memory: Clean up the memory of the model frequently and close unnecessary background running programs to keep your phone in tip-top shape.

Improper operation leads to black screen: Try not to open a lot of software at the same time, which takes up a lot of memory and is easy to black.

Software problem: According to your own phone's old and slow memory or configuration, Zhengdan is loaded with the right mobile phone software. If the phone configuration is low, it is easy to cause a crash if you want to run too large software.

In fact, today's smart phones, like computers, must be taken care of often when we use them, so that they will run smoothly.
