Android controls WiFi related operations the full name of WiFi is wireless Fidelity, also known as the 802.11B Standard, is a high-speed wireless communication protocol, transmission speed can reach 11mb/s. In fact, Wi-Fi does not require excessive control (when WiFi is successfully connected, you can communicate dir

On the Android phone, after connecting to Wifi, the password is generally invisible. Is there any way to view these passwords? There are two methods. One is to view the wifi configuration file and the other is to use commands. For the first type, there are already a lot of online tools, namely, root first, and then use
