There are many reasons why your phone freezes, and I will briefly talk about it here. The causes of phone crash are broadly divided into hardware and software issues. 1. The design defects of the hardware itself, the damage of the hardware and the improper operation.
For the design flaws of the hardware itself caused by the mobile phone often crashing, we can only obediently 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 circuit must be in a more stable environment to work normally, if the mobile phone often works in a humid environment or is subjected to strong vibrations from the outside world, it may crash.
For example, sometimes we accidentally drop our phone on the ground, and the phone may freeze. Therefore, we must treat mobile phones kindly and try to handle them gently; Don't let your phone get into water and try not to use it in a humid environment. Usually, if we operate the phone improperly, it will also cause the phone to crash.
Especially when we are sending text messages, if the speed of key operation is too fast or the continuous SMS bombardment in a short period of time, the CPU load of the mobile phone 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. Second, there are fatal flaws in software design. Crashes caused by software defects generally have the characteristic of crashing every time a command is run, that is, every time the same operation is performed.
If your phone keeps crashing like this, you can preliminarily conclude that it is due to software problems. To solve such a crash, it can be solved by software upgrade. At present, all major mobile phone manufacturers have set up customer service centers, and they all provide free software upgrade services.
If you do the upgrade yourself, please make a backup in advance to avoid the software cannot be restored after the phone upgrade fails. In fact, it is normal for a mobile phone to crash just like a computer to crash, 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 often crashes, you have to pay attention, it is best to send your phone to the customer service center for maintenance, that is the best solution.

Hello! Hopefully, the following will be helpful to you.
Flashing is risky, and this process can cause your phone to become bricked and unable to turn on. Please read the relevant tutorials carefully before you do it, use the official ROM when flashing, the third-party ROM cannot be flashed into the mobile phone under normal circumstances due to authorization problems. >>>More
