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 smart phone is a Zen for the sake of playing 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 that the rock suspect pin 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 rough mobile phone to call your own ** try, 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.

If the card brush fails and you can enter the coal digging mode, it is recommended to use the line brush;
