Why does the phone always have a black screen, and what is the reason why the phone always has a bla

1.Memory issues.

When the phone stores too many things, it will not only slow down the operation speed considerably, but it is also easy to go black during the running of the program, and then automatically exit the program. When 80% of the phone's memory is occupied, it may freeze or go black. In this case, it is easy to do, press and hold the home button of the phone, and call up the recently run program to exit.

Pay attention to uninstalling software that is not commonly used during use, and develop a good habit of quitting the program if you don't use it.

2., contact problems.

For some people, it is common to drop a mobile phone on the floor. All we can see is the loss of appearance, but if the phone is often dropped, or in a hot and humid environment such as a bathroom or sauna. The screen may be black due to loose or short circuit of the screen cable, and in severe cases, it may be caused by moisture and the waterproof sticker may turn red or even mold on the motherboard.

There's no good way to do this, it depends on the usual level of care.

3.Mobile phone film.

When I saw this once-time honey, I also felt that it was quite a pit, and I was concerned about the film. If the distance sensor is blocked during the film, it will affect the brightness and breath of the mobile phone screen. It's better to find an ancestral master for this film.

4.Application Software Conflicts.

There are many apps installed in the phone, but some apps are impulsive, and when running one of the apps, the screen suddenly goes black or quits for no reason. Of course, exiting one can be a problem with the app itself. In this case, you need to look for and uninstall this software.

5.Virus in the phone.

Nowadays, there are so many virus traps on mobile phones, and if you don't pay attention to it, you can easily fall for it. After being hit, some virus Trojans will modify the mobile phone system, causing the mobile phone to malfunction. In serious cases, it can also steal our private information. It is necessary to have a regular antivirus on your phone.

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. Here are some basic causes and solutions that cause black screens.

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.

Of course, it is recommended that you do not 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, let's talk about the standby principle first, because 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.

You can give it a try. 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.

What's going on with the black screen as soon as the phone hits**.

Black screen when operating specific software If your phone is used normally and only turns on a specific program, it may be caused by the software itself or incompatibility with your phone. Click the "home button" or force the shutdown and reboot to exit the black screen page of the software; Go to "Settings" - Application Management", find the software, "Clear Data" and "Clear Cache" to clear the cache data generated by the software when it was running in the past; If the software version is too low or there is a compatibility problem with the mobile phone, you can uninstall the software and re-install it in the "Software Store". Irregular black screen If your phone has an irregular black screen, you can check the following reasons.

The phone's running memory does not have enough space, and you need to develop the habit of closing background applications in time; The storage space is not enough, and there is no extra space to save the cache files when the program is running; Go to "File Management" to view your phone's available storage, or you can select "File Cleanup" to clean up unwanted cache files; Recently** or updated software and the system is not compatible with each other, quit or uninstall these software; If the phone is damaged by external forces (collision, water ingress, etc.), you can bring the phone to the OPPO service center for processing.

If it's not a hardware or system failure, why not try to adjust the screen display time a little longer?

Mobile phones can be said to have become a must-have daily necessities for most of us, if there is a problem with the mobile phone at any moment, I believe many people will not be able to stand it, and the black screen of the mobile phone is one of the most common problems, so why does your mobile phone have a black screen? Is there a solution?

Personally, I think it's too long to standby! If it can be used for a week after restarting after the black screen, it is a long standby time!

The black screen is basically caused by insufficient memory, too many cache files in the phone will occupy memory, and too many processes will also occupy memory. The next Android optimizer optimizes the process and cleans up the cache files.

I used to use a clamshell, and it always went black....It's a loose circuit board, and it doesn't cost money to repair it. Are you clamshell?

In this case, either the battery is not working, or the phone screen bus is broken, or there is a problem with the motherboard. Take it to the after-sales service center of the mobile phone brand to check it, confirm which one is broken, and then replace it.

The software used doesn't match the hardware very well.

It is recommended to change your phone.

Or will be used on the spot. However, you should often close some other apps in the background. Clear your phone junk.
