Reasons for the black screen of the phone:

1.In general, when the phone has too many things to store, the phone runs slowly, and even when the memory is 80% occupied, there may be a black screen of death.

2.The contact of the parts of the mobile phone screen is loose, which can also directly lead to the black screen of the mobile phone, and it is difficult to find at the same time, and it takes a lot of tests to find it, which is generally caused by the mobile phone being hit.

3.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.

4.The system ROM package used to flash the phone cannot perfectly support the phone, or improper flashing operation will also cause a black screen when using.
