Please enter the settings and check the remaining storage space:
1. Insufficient storage space (less than 10%)
When the available memory of the mobile phone exceeds 10%, the prompt of clearing the space of the mobile phone will disappear automatically. If you are prompted that the storage space is insufficient, please refer to the following methods to solve it:
1. Clean up storage space
(1) It is recommended to uninstall applications that are not commonly used, because downloading too many applications will take up a lot of memory;
(2) Clean up the equipment space: enter the mobile phone housekeeper and choose to clean up the unnecessary data. You can also use one-click optimization to release storage space according to the scanning results and cleaning suggestions.
2. Check whether multiple multi-users/privacy spaces are used.
Adding multiple users and opening privacy space will take up your storage space. It is recommended that you can delete multiple unused users or privacy spaces:
Warm reminder: If you don't use multi-user/privacy space, or your mobile phone doesn't support this function, please ignore this scheme.
(1) Enter the phone settings and search for multiple users to see if there are any created and unused multiple users. If so, click multiple users and select Delete User.
(2) Enter the mobile phone settings, search the privacy space, and see if there is any privacy space that has been created but not used (display on means that no privacy space has been created, and display on means that privacy space has been created). If yes, please click on the three points in the upper right corner and select Delete Privacy Space.
3. Move the large file to the memory card and save it.
If your mobile phone supports inserting an external memory card, it is recommended that you insert an external memory card and move the files such as pictures, audio and video stored in your mobile phone to the external memory card to free up storage space. The operation is as follows:
Go to file management > browse > my mobile phone, find the file to be moved, press and select the file, and click the move button to move it to an external memory card for saving.
4. Modify the default storage location of the memory card.
If your mobile phone supports inserting an external memory card, I suggest you insert an external memory card and go to Settings >; Storage > default storage location, change the default storage location to an external memory card, so that the memory of the mobile phone itself will not be occupied too much.
5. Back up the data to the cloud host.
If the memory is insufficient, you can also back up the data to cloud hosting. Enter mobile phone settings, search for cloud hosting, open applications that need to use the cloud, and back up data to cloud hosting.
6. Restore the mobile phone to the factory settings.
It is recommended that you back up the data (third-party applications such as QQ and WeChat need to be backed up separately), enter the phone settings, search the factory settings, and complete the operation of restoring the factory settings according to the phone interface prompts.
Second, the remaining storage space is sufficient.
Please refer to the following methods for troubleshooting:
1. Maybe you visited some application promotion websites in your browser, and the page disguised as a reminder that the device storage space or running memory is insufficient to promote the application "optimization" system to you. It is suggested to clear the browser cache in the browser settings first, and then update the virus database of the mobile phone housekeeper to block fake websites:
EMUI 8。 X and below: mobile phone housekeeper > virus killing > settings, and select automatically update virus database.
Emui9.x/10.x/11.x: mobile phone housekeeper >; Settings, select automatic update virus database/network virus killing.
2. System update and upgrade failed, prompting "Internal storage is insufficient, please delete at least XXX and try again" or "Not enough space to upgrade": system upgrade needs to reserve some space, please clean up enough space according to the prompt.
