1, memory problem

If there are too many things stored in the mobile phone, it will not only make the mobile phone more and more stuck during normal use, but also cause the problem of black screen during the use of the mobile phone, resulting in the mobile phone automatically quitting the corresponding application. At this time, we need to call up the recently running applications of the mobile phone and exit the programs that are not commonly used or currently used.

2. Contact problems

Many friends will accidentally drop their mobile phones on the ground during daily use, which will not only damage the appearance of the mobile phone, but also cause the cable on the screen of the mobile phone to be loose or short-circuited, resulting in the black screen of the mobile phone, so when using the mobile phone in daily use, be sure to hold it steady.

3. Application software conflict

When people use mobile phones in their daily lives, they will inevitably use many applications, some of which are incompatible with mobile phones. At this time, when the software is running, it is easy to have a black screen or quit for no reason.

At this point, we need to find the conflicting application and uninstall it. If you can't find the conflicting software in the problem, it is recommended that you back up all the important information on your mobile phone and then restore it to the factory settings.

There is a virus in the mobile phone.

Nowadays, there are many mobile phone viruses, and many mobile phones will be poisoned if they are not careful. After poisoning, the mobile phone system will be tampered with, resulting in the failure of the mobile phone. At this time, it is necessary to disinfect the mobile phone regularly.

5, battery problems

The longer the mobile phone is used, the shorter the service life of the battery will be, which will lead to the phenomenon of black screen or restart of the mobile phone.

6. Software failure

Some applications in the mobile phone will have problems such as black screen or flashback when used for a long time, so we need to check and update the software in the mobile phone regularly. If the latest version is available, it is best to upgrade the application to the latest version.
