The reasons why the phone won't turn on are roughly divided into hardware and software problems.
1. Hardware issues:
Generally, it is mainly due to the design defects of the hardware itself, the damage of the hardware, improper operation, etc.
For the design defects of the hardware itself, the mobile phone often crashes, there is no way to solve it, but to send the mobile phone to the customer service center for maintenance.
If the hardware is damaged, it can also lead to frequent crashes. Mobile phones are sophisticated electronic products, in which the circuits must be in a more stable environment to work properly, if the mobile phone often works in a humid environment or is exposed to the outside world.
For example, sometimes we accidentally drop the phone on the ground, and the phone may crash. Therefore, we must treat mobile phones kindly and try to handle them gently; In addition.
Do not use your phone in a humid environment.
Usually, if we operate the mobile phone improperly, it will also cause the mobile phone to crash, especially when we are sending text messages, if the speed of the key operation is too fast or the short message bombardment is continuously in a short time, resulting in the mobile phone CPU load is too large, and the heat generated by the CPU cannot be dissipated in a short time, so it will cause the mobile phone to crash. In addition, there are other factors that cause crashes due to hardware problems, such as aging hardware, too bad environment for using the phone, etc.
2. Software issues.
The main reason is that there is a fatal bug in the software design of the mobile phone, which causes the crash. When the phone runs the program, a command error will occur, a bit like an illegal operation in the computer, and there may be a crash.
Solve such a crash can be solved by software upgrade, now the major mobile phone manufacturers have customer service centers to provide free software upgrade business, in the upgrade to solve some software bugs, reduce the probability of crash.
It is best to go to the customer service center to upgrade the software of the mobile phone, and if you do the upgrade yourself, please make a backup in advance, so as not to restore the software after the mobile phone upgrade fails.
In fact, it is as normal for a mobile phone to crash as a computer, as long as we treat it correctly, there will not be so many people complaining that their mobile phone is dead again. But if your phone crashes frequently, you have to pay attention to it, and it is best to send your phone to the customer service center for maintenance, which is the best solution.
