Reasons for the black screen of the phone:

1.Under normal circumstances, when the mobile phone stores too many things, many friends can feel that the mobile phone is running too slowly, and when their mobile phone is occupied by 80% of the memory that can be driven, it may crash.

2.This is the loosening of the contact of the mobile phone screen, which is not a big problem, but it can directly cause the black screen of the mobile phone, and it is difficult to find that it has to go through a lot of tests to find, which is generally caused by the mobile phone being bumped.

3.It is common for many mobile phones to have a black screen after using it for a long time, the main reason is that the effective use time of the mobile phone battery is 1 year, or it is three years but there is a problem in one year, and excessive use leads to the aging of the mobile phone's battery and insufficient voltage.

4.There are a lot of applications for smartphones nowadays, but there are some software that are inherently conflicting, which can also lead to a black screen, so the black screen after installing a lot of software is basically this reason.

5.Many people are keen to flash the machine and use a better system, in fact, some system mobile phones are not very supportive, and some are not complete, resulting in a black screen when using it in the future.

Hello, there is no way, you can only take the machine directly to the official maintenance department.

If the Samsung phone can't be turned on after the sudden black screen, it is very likely that it is a problem with the internal hardware of the phone, if it is for other reasons, it is easier to solve, usually speaking, the problem of the black screen can be solved in this way:

Usually there are two types of black screens: one is the black screen in use, and the other is the standby black screen.

There may be two reasons: there may be a problem with the software itself, such as the software itself is unstable or does not match the mobile phone system, and uninstalling the software can solve this problem; If the software is not compatible with each other, it is necessary to install and uninstall the software one by one, and experiment to check which software is the problem. If you find it, uninstall it, and the problem will basically be solved.

The black screen in standby is mainly due to the fact that the mobile phone will automatically turn off the screen if it does not detect the key trigger signal for a long time, that is, standby, when you need to use the mobile phone, the button will activate the circuit in the mobile phone, and then the screen will light up.

The reason for the black screen may be because the mobile phone system sends a command to light up the screen, but the screen cannot respond in time due to the delay in the transmission of the circuit, so the black screen is caused. In this case, you don't need to be in a hurry to recover, wait for a while or use the ** around you to dial the phone with a black screen, if you can get through, this problem will be solved.

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.

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.

Workaround:

First confirm whether it really can't be turned on. Sometimes when you can't turn on the phone, you will panic and feel that the phone is broken, but it is not. There are many situations where the machine may not be turned on at one time, or even several times, because even if there is no problem with the hardware, there may be problems with the software, so first check the power supply, battery, connection, etc., or try several more boot attempts.

If you still can't turn on the phone, you can try flashing the phone directly without thinking of other methods. In this case, the phone will generally be able to return to normal, unless there is a problem with the phone's hardware. In this case, you must ensure that there is no very important information in the mobile phone, otherwise once the flashing data is gone, it will be too late to regret it.

If you turn on normally after flashing, you can, if you still can't turn on, you need to go to the designated point to overhaul or re-choose a mobile phone, once the hardware is damaged, even if the mobile phone is repaired intact, it will cost a lot, more often such as the screen, the motherboard is a very expensive place.

There are many reasons for the black screen, system issues, software conflicts. If the screen is damaged, it will turn into a black screen, so it is recommended to try the following:

One. If it's a black screen all the time:

Press and hold the power button for more than 10 seconds to try to power on and off again. If the fault persists, it is recommended to send the phone to the nearest Samsung service center for testing.

Two. If it is sometimes a black screen:

1.It is recommended to uninstall the third-party plug-in program that operated before the black screen.

2.Back up your phone's data (**book, SMS, multi** files, etc.), and restore factory settings (Settings - Privacy Reset - Factory Reset).

If the problem persists, please bring the purchase invoice, repair card and machine to the Samsung service center, and the engineer will inspect the machine and deal with it.

Take the battery out and reinstall it to clean up the memory after booting.
