If your device is running low on memory, you can try to adjust and improve it in the following ways:

1. Frequently or regularly use the mobile phone acceleration function of security software such as Le'an to clean up background applications, which can effectively release the running memory;

2. It is recommended to uninstall useless or infrequently used software, which can prevent the self-start of such software and occupy running memory;

3. After the application is finished, try to use the exit function of the application to completely exit to avoid the application hanging in the background and occupying the running memory;

4. It is recommended to use the built-in music security software for self-start management, limit the boot start project, avoid occupying too much running memory, due to the difference in the music security version, there may be differences in the menu path, take the music security version as an example, the path and operation steps are as follows: "music security" - "mobile phone acceleration" - "self-start management", the self-start project that needs to be restricted is manually closed, please refer to it.
