For old mobile phones that are no longer used, you can delete the stored data through the "factory reset" or "one-click delete" functions, but this does not really clear the data. According to experts, data is like a book. The above simple operation only deletes the table of contents of the book, but the content of the book is still there.

Second-hand mobile phones have become one of the sources of personal information leakage and formed a gray industry chain. In view of the existing problems in this field, there is an urgent need to further solve the pain points, difficulties, and blocking points. For example, only by improving the top-level design of mobile phone recycling, establishing a formal recycling system, and implementing full control over all links can the market become active.

At present, domestic supporting regulations for the recycling and disposal of used mobile phones are not perfect, and subsidy policies are relatively lacking. Further research needs to be strengthened to make up for the shortcomings. At the same time, we must strengthen industry self-discipline and increase the protection of personal information. For example, recyclers can be required to completely delete internal data when disposing of second-hand mobile phones. They are not allowed to back up without the user's consent, and are not allowed to illegally resell user private information. Any violation will be severely punished. Mobile phone manufacturers need to establish an extended producer responsibility system and a corporate reverse logistics system to promote recycling cooperation upstream and downstream of the industry chain.

Only by establishing and improving a formal recycling system, standardizing market order, improving transaction rules, cracking down on illegal processing, and ensuring the security of personal information can users' concerns be dispelled, old mobile phone resources can be rationally utilized, and " Turn waste into treasure.”
