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 a short congratulatory message, if the speed of the 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, mobile phone crashes are as normal as computer crashes, as long as we treat it correctly, there will not be so many people complaining that their mobile phones are 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.

1.There are several reasons why your computer won't shut down:

1) Defects in the automatic shutdown program in the system file. Enter the command: "rundll32 ,exitwindows" in "Start Running" to see if it can shut down normally, if this command can shut down normally, it means that the automatic shutdown program has some kind of defect, if you are using a Windows98 system, check the integrity of the system files and patch the files in the "Start Program Attachments System Tools System Information Tools System File Checker".

If you use a different system (ME 2000 XP), you can also patch files in the corresponding project. If patching the file still doesn't solve the problem, you can only reinstall the system. If you run "rundll32, exitwindows" and cannot shut down normally, it may be that some system programs in the operating system are defective, but the solution is still to patch the system or reinstall the system;

2) Viruses and some defective applications or system tasks may cause shutdown failure. Check for viruses and close all applications before shutting down. Because some applications are loaded at system startup, you can use the command in the Startup menu (in Start Running:

msconfig"), in order to see if there are any files that affect the shutdown (of course, they will not take effect until they are restarted);

3) Peripherals and drivers are not compatible well and cannot respond to rapid shutdown. You can enter the command "msconfig" in Start Running, select "Advanced" in the "General" tab, and "Disable Rapid Shutdown" in the window that opens.

If you suspect that the peripherals are faulty, you can also uninstall the peripherals one by one to check them so that you can find the affected peripherals.

2.If the computer is stuck and cannot be shut down, you can press and hold the power button to force it to shut down.

1. Check whether the battery is in poor contact.

There are many people whose mobile phones frequently crash and restart, but they can't find the problem when they send them to the repair shop, which is likely to be the poor contact caused by the oxidation of the contact points of the battery. This is often the case on relatively long phones and can be easily overlooked. The way to check is simple, gently pat the back cover of the battery a few times to see if the phone freezes or restarts.

The solution is also very simple, just replace it with a new battery.

2. Check if there is a memory card problem.

If the phone crashes are no longer frequent after removing the memory card, it is very likely that the phone memory card data protection or data conflict. It is recommended to delete the relatively unimportant data one by one, or you can format the memory card directly. When formatting the memory card, pay attention to 4K pairs, select 4096 for the allocation unit size, and FAT32 for the format.

3. Check whether the system files have been deleted by mistake.

Just like the computer's C drive system files are deleted by mistake, after the phone obtains root permissions, if the system files are deleted by mistake, it is easy to crash and restart, or even directly become bricked and cannot be turned on, which can only be saved by flashing the phone. You can use the official line brush tool for line brushing, which is 100% effective.

4. It may be a system compatibility issue.

In the system pushed by the vendor, some development versions of the system are not so stable, and there will even be many problems. If your phone freezes or restarts after updating the system, it can be very effective to swipe back to the stable version of the system.
