Why is the phone old black screen, what is the old black screen of the phone

If the phone screen is always black, it is likely that the phone has been flooded or dropped, resulting in internal wiring problems.

The phenomenon of black screen often appears on the phone, it should be a problem with the system of the phone, it is recommended that you update to the new system and so on.

My black screen is not your one? You can adjust the brightness to the luminosity automatically.

The reasons why the mobile phone always has a black screen are as follows: 1. Many models have a distance sensor on the top of the mobile phone, and when the upper part of the screen is blocked when making a call, the screen will go black. 2. When the memory of the mobile phone is large, the screen will also be black.

You start by finding the settings menu. Find the corresponding options in the settings!

The reasons for the analysis of netizens on the Internet are as follows: Recently, there are always brothers and sisters in the altar who ask about the black screen of the mobile phone, I will write out my experience and share it with you. At that time, my phone often went black when I bought it. I've taken a closer look at this issue.

There are two types of black screens: one is standby black screen; One is the black screen in use (the black screen in use can also be understood as a crash). Most of the black screens in use occur on 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, and you can 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 the uninstall problem, it can basically be solved.

Here 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. Just install some software recommended by friends in the altar.

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. When you need to use your phone, a button will activate the power-saving circuit. Then the screen lights up!

The reason for the poor black sox screen is that the screen triggers the circuit delay reflected. That is to say, the mobile phone system has issued a command to light up the screen, but due to the delay of the circuit, it was not sent successfully, and the result is that the screen is not lit successfully. But the phone system thought it was already lit.

So there is the problem of 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.

If there is a black screen, there is no need to panic, 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. After many years of practice.

It can generally be returned to normal immediately! In this way, it basically does not have a big impact on the use.

Although it is very annoying to have a black screen frequently, it seems that there is no solution to the black screen completely. So I can only endure it.

It is estimated that if you want to completely solve this problem, you can only hope that Nokia can upgrade it again.

Solution: In the screen saver, select: Always

In this way, there are always words moving on the screen, so that they will not go black at the first touch.

I didn't use 5320 for too long.

I don't know if this method works (when I first bought it, it was dark once a day for the first two days), and now I use this method to never be black.

Dear, I'm glad to answer for you: Why is the phone always black screen Answer: 1
