Hello, everyone. The meeting will answer your questions. What happened to the old mobile phone? many people don't know what the old mobile phone is used for. Now let's take a look at it.

Answer:

1. Recycling old mobile phones usually means recycling precious metal materials, such as circuit boards, speakers, housings, LCD screens, cameras, batteries, etc. They all contain gold, silver, palladium, copper and other metals. In addition, some good old phones will be refurbished and returned to the market, the dismantled parts can usually be used for a few more years to ensure their best use, and the refurbished phones can also be sold for a certain profit.

2. Will recycled old mobile phones reveal personal information?

3. Yes, the current recovery of mobile phones is mixed; for example, on the second-hand mobile phone recycling machine, some people find that they need to plug in a data cable to detect the phone, the iPhone needs to "trust the computer" after connecting, and the Android phone needs to turn on "USB debugging mode". This means that the permission to store the phone should be released to this machine. At present, many mobile phone maintenance shops in the market have data recovery services, and the Internet is filled with a large number of data recovery software. These services say that even if you delete the phone data, some data can still be recovered.

4. Disposal methods of waste mobile phones:

5. Selling mobile phones after use is a good thing for the reuse of resources, but for the sake of data security, try not to discard or sell them. If you really want to sell, these early actions may help you: first take out the memory card (which can be ignored for phones without memory cards), and then delete all personal information, including accounts, contacts, text messages, photos, videos, etc. And restore the phone's factory settings; the most critical step is to store a large number of unimportant video or music resources on the phone, and make sure that the phone's space is completely filled and covered several times, so that even if it is later restored by the data, it could also be irrelevant data at the top of the storage.

This is the end of this article. I hope it will be helpful to all of you.
