It is prudent to sell waste mobile phones

A recent report from the second hand e-commerce platform revealed that a survey of tens of thousands of respondents found that up to 92.5% said there were 1 or more mobile phones in the home. Many of them have chosen to sell their old phones, and the market is huge. Research Institute IDC predicts that by 2020, sales of used handsets will climb to 222 million 600 thousand, with an average annual compound growth rate of 22.3%.

Because many old and end-of-life mobile phones contain users' personal privacy information, some people have started in this respect.

Earlier, there were several media reports, in some places such as railway stations, there are some self-service charging devices, after use, the phone was forced to install a variety of APP. This shows that the risk of privacy theft is greatly improved after the access to mobile phones is acquired.

How do you deal with the old cell phone?

It is a good thing to reuse resources without having to sell them. But for data security, try not to discard or sell them. If you really want to sell, these prepositions will help you.

First, take out the memory card (no memory card phone can ignore this), then delete all the personal information, including account, address book, text message, photo, video and so on, restore the phone factory settings.

The most critical step is to save a lot of insignificant video or music resources on the phone, confirm that the cell phone space is fully filled and repeated several times, so that even the subsequent recovery can be the most insignificant data in the storage.
