Now that the Internet is so powerful, I am worried about which technicians steal my personal informa

I saw a lot of personal information on the Internet, and I doubt which technical personnel obtained the information of many people through their own means, which is why we are subject to some inexplicable fraud calls.

I use an Android phone. Although Android has many problems, its price is relatively cheap, and it is also functionally ready to fully meet our requirements. As for the issue of whether Android is safe, there has not been a black one. Always black screen, crash, this may be related to the hardware of the machine itself, and has nothing to do with security.
