There are three ways to deal with the lack of memory in Huawei's mobile phone system: regularly cleaning the background programs of mobile phones, transferring APP applications to SD cards, and deleting apps that are not commonly used.

First, regularly clean up the background programs of mobile phones:

1. If there are too many programs running at the same time in the mobile phone, the memory will be insufficient.

2. Use the mobile phone housekeeper for background cleaning.

Second, transfer the APP application to the SD card:

1. Install the APP application in the mobile phone to the SD card.

2. Move the memory already installed in the mobile phone to the SD card.

3. Store the photos on the SD card.

Third, delete apps that are not commonly used:

1, uninstall apps that are not commonly used.
