Will mobile phones steal personal information after recycling?

Perhaps, in today's smart phones, simply restoring factory settings and deleting files does not mean that the information is completely deleted. When a file is "deleted" on the mobile phone, in fact, the system only deletes the indicated path of the file, which means that most people can't find the file, but the essential content information is still saved in the mobile phone.

Therefore, the stored content information can be restored before the mobile phone, and the technical threshold is not high. At present, in some informal second-hand mobile phone recycling shops, some people will restore the information stored in their mobile phones in this way, such as mobile phone address books, text messages and other contents involving personal information, and then sell them again to earn huge profits.

Recycle old mobile phones

First of all, the sales of used mobile phones should be carried out on big platforms and hypermarkets as far as possible, and personal channels or small shops should be avoided as far as possible. Secondly, don't rush to sell your old mobile phone after it is replaced. Before selling, in addition to restoring factory settings and deleting old files, you can also choose to download "file shredding" software to repeatedly overwrite and copy outdated mobile phones and computers.

Users can connect the mobile phone to the computer, first delete all the contents in the mobile phone, then write a new large file into the mobile phone, and repeat it several times to fill up the space as much as possible. This can basically ensure that the personal information and traces in the old mobile phone are completely removed.

Try not to save sensitive and confidential information on your mobile phone. Important information should be deleted as soon as possible after being saved and used. After repeated data coverage, the probability of data recovery will be greatly reduced.
