Are the Android phones we use now safe?

I use an android phone. Although android has a lot of problems, its price is relatively cheap, and it is ready in terms of functions. It can fully meet our requirements. As for the security of android, there are no hacks. , I always have a black screen and crashes, which may be related to the hardware of the machine itself, and has nothing to do with security.

Android is one of the largest mobile phone sales in China. It illustrates the importance of android phone performance. There are many on the Internet, mainly referring to the security risks of android, and there are still performance defects. People have tried to use cell phone portable jammer kits to protect the security of their phones and test them.
