If you use Huawei mobile phone, you will be prompted that the internal storage space is insufficient, and the processing method is as follows:

1. If the mobile phone supports the Micro SD card, if the Micro SD card is inserted, move the large file to the Micro SD card for storage;

2. Import uncommon files into the computer for backup;

3. Clean up the storage space:

Downloading too many applications will lead to insufficient memory. It is recommended that you uninstall infrequently used applications to free up memory.

File management? & gt？ Clean files > check the data to be cleaned > one-click cleaning.

Mobile phone housekeeper? & gt？ Space cleaning (or cleaning acceleration) > check the data to be cleaned >? One-button cleaning.

After long-term use, WeChat, QQ and other applications will produce a large number of cached data (pictures, videos, etc. ) to occupy storage space. I suggest you selectively clean up the storage space of WeChat and QQ applications.

If the memory is still insufficient after trying the above methods, it is recommended to back up important data and restore the mobile phone to factory settings.
