I don’t know if the mobile phones have encountered this situation:
, the phone is still full, and the screen suddenly turns off the screen
, and then it can’t turn on the machine, and then it can’t be turned on for a while. But suddenly it starts to charge from 0,
,
, and it can continue to use
without changing the phone, just because it is afraid that the black screen will be delayed again. But what exactly causes this situation?
at least "dead" and "dead". It is not
, the black screen of the mobile phone can be divided into internal and external reasons. The internal reasons include memory, software conflicts, etc., external problems include contact, battery, etc. Today I will tell you some of the reasons for the black screen of the mobile phone. Friends, come and have a look!
Memory problem:
When the phone stores too much things, it will greatly reduce the running speed of the phone. During normal use, the phone will become more and more stuck, and there will also be a black screen problem during the use of the phone, causing the phone to automatically exit the application. When the memory is occupied by more than 80%, the phone may crash or black screen.
If this kind of problem occurs, you can try to call up the recently running application of your phone and exit programs that are not used frequently or are currently unusable. Normally, you should also develop a timely clean up idle running programs to reduce the use of running memory.
Contact problem:
Many people do not pay attention to details when using mobile phones, and often encounter various bumps and bumps. Injurying the outer shell of the mobile phone is a trivial matter, but it will cause poor contact, such as loose or short circuit in the screen cable, which will also lead to black screen. So if you want to solve this problem, you must develop good running habits when using your mobile phone every day.
Use software conflict:
People use mobile phones in daily life, and many application software will inevitably follow many application software on mobile phones, and some application software is incompatible with mobile phones. At this time, the software is running, and it is easy to have black screen or exit for no reason. At this time, we need to find the conflicting application and then uninstall the sword energy.
virus invasion:
Of course, sometimes the black screen of your phone is not because your phone has small memory, but may be infected by the mobile phone virus . These viruses will invade the mobile phone system, which may cause your phone to black screen in the process. Therefore, don’t download and use software through irregular channels, or turn on USB debugging mode . These small details may cause your phone to be hit.
It is recommended to download the APP through the official website of the APP or the app store that comes with your mobile phone. Do not easily click on links or websites of unknown origin, and do not easily scan unfamiliar QR codes.
battery problem:
battery is an important energy source for mobile phones to run. The longer the mobile phone is used, the shorter the service life of the battery will become. If there is a problem with the battery, such as aging, overcharging and discharge, or poor battery contact, it will cause the phone to black screen. This problem is easier to solve, just replace a battery directly.
System software problems:
Some software is downloaded from regular channels, but if it has not been upgraded for a long time, the software may be incompatible with the mobile phone system. So although not all software used must be upgraded frequently, it should not be upgraded for several years, otherwise people may go on strike.
or above is the reason why the black screen of the mobile phone cannot be turned on. Do you all know? If you want to know what tips you are welcome to leave a message in the comment area~
