Operation method
1、 It is still to restore factory settings. Android phone users only need to click "Settings" - "All Settings" - "Backup and Reset" - "Restore Factory Settings" - "Reset Phone" in sequence. This deletes all data in the phone. Apple phone users can restore factory settings by selecting "Erase all contents and settings".
2、 After the phone is restored to factory settings, we store some large files that do not involve privacy, such as videos downloaded from the network, into the phone until the phone's memory is full, and then restore the phone to factory settings, which can be repeated several times.
3、 Some friends are puzzled by the operation reason analysis. Why bother? Aren't they all deleted? You should know that after the phone is restored to the factory settings, others can still find your data because we just made a "delete" mark in the phone and did not really erase the data. This is why it only takes a few seconds to delete a file of several gigabytes, while it takes a few minutes to copy a file of several gigabytes. However, these data still exist in the mobile phone memory, and the deleted data can be retrieved through professional software. Now you should understand the reason for repeatedly copying a large amount of data to the mobile phone memory? It is to overwrite the original data, so that these data will disappear from the phone memory completely, and there is no possibility of recovery.
4、 Some friends may still worry that their personal information has not been completely deleted. We can make the final check, and others can scan it with professional data recovery software. Of course, we can also do it ourselves. Many of these software users only need to search online, download and install them. Check whether the privacy data is really completely deleted and whether it is possible to restore it. In this way, we can safely dispose of the old mobile phone.
5、 WeChat Alipay Security Settings WeChat and Alipay are one of the most frequently used software. These accounts involve important personal privacy, including fund security. WeChat has an account protection function. Turn on this account protection function. The verified mobile phone in WeChat is set as a common login device. The next login does not need to be verified. We can delete the common device before dealing with the old mobile phone. Others can take your old mobile phone and know your WeChat account password, but also can not pass the verification and can not log in to your WeChat. To delete a common setting, open WeChat, click "I" - "Settings" - "Account and Security" - "Account Protection", and then delete the old phone from a common device.
However, Alipay now only stipulates that one account can only be logged on to one device at the same time. By default, there is only one common device, and other device logins need to be verified. The security is still high, so you can use it with confidence. Now mobile phones are playing a more and more important role. We have more and more idle old mobile phones. It is more and more important to protect personal privacy. How do you do before dealing with old mobile phones? Maybe you have a more brilliant way. Welcome to discuss it in the message area. Thank you!
