The Solution of Xiaomi 4 Mobile Phone Card

1), the software does not quit completely, but stays in the memory, which will greatly affect the speed of the mobile phone. At this time, it is necessary to clean up the applications running in the background in the memory. You can use "360 Optimization Master" and click Memory Cleanup.

2) One-click cleaning. After cleaning, the mobile phone has more available memory, and the mobile phone will be faster.

3) There is another reason why the memory of the mobile phone is not enough, that is, the installed applications are all in memory. At this time, you can use the "Software Move" function of "360 Optimizer" to move the application in memory to the SD card. Click software management->; Software movement.

4) Select the program to be moved to SD card, and click Move to SD card. After moving the software, more memory is available and the software runs faster.

Reason 2: There is a program upgrade in the system.

1) When the mobile phone is connected to the internet, the application will be upgraded in the background, which will take up a lot of memory and the processing process of the mobile phone processor, so the mobile phone will respond slowly. Generally, this situation will be restored after the upgrade is completed.

2) For this reason, it is suggested not to install too many applications in the mobile phone. I tried, and my mobile phone didn't connect to the Internet for a while. When connected to the Internet, there are 100 applications in the mobile phone upgraded at the same time. As a result, the fully charged mobile phone was dead after the upgrade. In this process, the mobile phone was basically useless and stuck.

Reason 3: The mobile phone is hot.

1) I don't know if you have noticed that after using it for a period of time, the mobile phone will feel very hot. At this time, the phone will be stuck, because the performance of the hardware will be reduced when the phone is hot.

2) The solution is not to use the mobile phone when it is hot, turn off the screen for a while, and then use it when it is cold.
