Huawei's mobile phone has been restored to factory settings. Are the contents still there?

After the factory settings are restored, the system settings file is gone, and the files under the memory card are still there.

Restoring the factory settings is to restore the mobile phone to the default settings of the mobile phone system, just like when it was just bought back and useless.

Such as the start interface, standby mode, operation shortcut keys, address book, timed reminder and other related system settings will be cleared and restored to the system default settings.

However, the factory settings will not delete the contents in the memory card, such as downloaded applications or SIM cards, such as SMS.

Extended data:

Smart phones use information storage methods similar to computers. When the user deletes, the information in the storage medium is not actually erased, but is marked as rewritable. When new information is stored, the original information can be overwritten, but when it is not overwritten, the information remains in the storage space.

At this time, you can easily restore this information by restoring the software, even if it is "restoring factory settings". Recoverable information includes: photos, short messages, WeChat chat records, address books, audio recordings, videos, etc.
