Why can't wechat go up? When I log in, I get a black screen.

Clean up the garbage of file management before downloading WeChat.

In use, the black screen is mostly caused by the third-party software downloaded by yourself, which is rare in this machine. It can also be subdivided into two types: one is that the software itself has problems, the software itself is unstable, or it doesn't match the mobile phone system, which is easy to solve and can be uninstalled; The second is the conflict between software, which is a bit troublesome to solve. It needs a software to install and uninstall it. If found, uninstall it, and the problem is basically solved.
