According to CTOnews.com on Oct. 3, Wechat Security Center has now released ten rumors on WeChat moments in September, including "restoring factory settings will ensure that data will not be leaked when selling used phones."

Among them, in response to the rumor that "restoring factory settings can ensure that data will not be leaked when selling old phones," the science refutes the rumor that this is tantamount to "marking" the storage space in the area where the deleted data is located. In fact, the original data is still there, and the original data will not be overwritten unless other data is stored (written) in this area.

The mobile phone resumes the factory settings only to simply restore the system files and delete the user data, and the contents on the internal storage chip of the mobile phone are not deleted completely. in fact, this is equivalent to "marking" the storage space in the area where the deleted data is located. In fact, the original data is still there, unless there is another data stored (written) in this part of the area. Only then will the original data be overwritten.

Therefore, in order to ensure the information security of the old mobile phone when it is sold, after the phone resumes the factory settings and restarts, it is necessary to fill the storage memory of the original phone and overwrite the original data by copying videos and downloading software many times, and then restore the factory settings.
