Selling your old phone safely: How to maintain your privacy

News on October 24, nowadays, mobile phone updates are constantly iterating, and many people will consider changing to a new mobile phone every two years. But what should you do with your old mobile phones? The best option is to sell second-hand mobile phones, which not only recovers part of the cost, but also contributes to the sustainable use of resources. However, the police remind: Selling an old mobile phone is equivalent to selling yourself, so be sure to thoroughly clean the data before selling.

The old cell phone you randomly sell may reveal your personal information. Before selling a phone, it's common to perform a format and factory reset. However, the police pointed out that even after formatting and factory reset, the formatted information may still be recovered. In order to increase the security of information, you can adopt the following more rigorous steps: After performing a factory reset, fill up the phone's storage space, such as downloading some large files, such as movies or TV series; then replace the original data and perform a factory reset again set up. In this way, even if the phone is tried to be restored by criminals, they will only get the newly downloaded movies and other files.

Although methods such as one-click deletion, formatting, and factory settings restoration can delete personal information in your phone, the security of the information cannot be completely guaranteed. 315 Information Security Lab has conducted special tests before, and the results show that operations such as one-click deletion, quick format, and unchecking "Format SD card and mobile phone storage" by default cannot completely clear the data.

#To ensure the safe deletion of personal information, you must choose to delete all stored items when restoring the phone to factory settings. For data formatting in hard drives and USB flash drives, the quick format option should also be disabled to ensure that the data is completely erased.

In today's Internet era, personal information is crucial to everyone, and mobile phones are an important information carrier. Therefore, better implementation of data cleaning steps will help keep personal information safe when selling or disposing of your old phone.
