3. The black screen of the mobile phone may be the cause of the mobile phone battery, and the battery of the mobile phone is removable, so there may be a poor connection between the battery and the mobile phone, which will lead to the black screen of the mobile phone. Moreover, battery damage and low battery power can also cause the phone to go black, especially if the battery has been used for a long time.

The possible factors of the black screen are:

1. Mobile phone parts malfunction.

When the mobile phone is flooded, dusted, etc., it may cause damage to the internal parts of the mobile phone; If the phone is dropped, it may cause the screen cable to loosen or the line to be short-circuited, resulting in a black screen or even no work.

Drying and stove baking, because the high temperature environment may cause secondary damage to the internal parts of the phone, the phone should be allowed to dry naturally.

Some friends may flash their phones, and in this process, it is very likely that the system files will be deleted, resulting in a black screen on the phone.

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.

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.

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 battery lasts too long, or the battery is overcharged and discharged, resulting in a shortened battery life, which in turn leads to a black screen or restart. This can also happen if the phone battery is in poor contact with the battery connector. This change the phone, or change the battery, you are free.

What to do if your phone has a black screen? Tell you what the cause is and solve the problem quickly.

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.
