When the mobile phone is used for a long time, applications, garbage, cache and various files will take up space, resulting in insufficient memory. You can try the following methods to solve this problem:

If the mobile phone supports sd card, you can install an sd card and move files such as pictures, music and videos to the SD card.

You can also clean up the storage space and use the cleaning function in mobile phone housekeeper or file management to clean up junk files.

File management-> Clean up files-> Check the data to be cleaned-> clearmaster

Mobile phone housekeeper-> Space cleaning (or accelerated cleaning)-> Check the data to be cleaned-> clearmaster

If you still prompt that the memory is insufficient, it is recommended to back up important data and restore the factory settings of the mobile phone.

2. What if Huawei's mobile phone prompts that there is not enough memory?

The mobile phone is out of memory. I suggest you optimize your memory by the following methods: 1. It is recommended to uninstall some unused programs.

2. If your device supports microSD card storage expansion, it is recommended to use microSD card (high-speed microSD card of common brand is recommended) to move personal files in the mobile phone to microSD card for storage. 3. It is recommended to manage cclean by mobile phone.

Click phone manager > accelerate cleaning. After scanning, click one button to clean up, or select the content to clean up according to actual needs. 4. After using WeChat, QQ and other applications, the storage space is insufficient, which may produce a large number of cached data (pictures, videos, etc.). ): I suggest you selectively clean up the storage space of WeChat and QQ applications.

Cleaning scheme: For example, on WeChat, go to WeChat Me > Settings > General > Clean WeChat storage space for selective cleaning; For example, if you use QQ, enter QQ, slide the screen to the right, and click Settings > Space Cleaning to selectively clean up. 5. If the memory is still insufficient after trying the above methods, it is recommended to restore the factory settings of the mobile phone after backing up important data (checking "Format internal storage space" can clean it up more thoroughly, but please back up important data to external storage such as computer, SD card or cloud first).

3. What if Huawei's mobile phone suddenly prompts that there is not enough memory?

You can free up space in your mobile phone system in the following ways:

1, enter the security assistant-mobile phone cleaning-scan and clean the junk files in the mobile phone.

2. Go to Settings-More Settings-Applications-Installed, and move the removable software to another storage space.

3. Go to Mobile Settings-More Settings-Applications-Installed and uninstall the software that is not commonly used in the system space.

4. If necessary, go to phone settings-More settings-Restore factory settings-Clear all data. Erasing all data will lose all data in the phone. Remember to back up relevant important materials before clearing all data.
