How to control another mobile phone with one mobile phone?

If you want to use one mobile phone to control another, you need to use some special applications or software. These applications usually need to be installed on two mobile phones at the same time to ensure that they can communicate and transmit data with each other. Some popular applications include TeamViewer, AirDroid and VNC browser.

TeamViewer is a remote desktop application that allows users to remotely access another computer or mobile device from another computer or mobile device. AirDroid is an application specially designed for Android devices, which allows users to communicate with other Android devices via Wi-Fi or the Internet. VNC Browser is another remote desktop application that allows users to access the desktop of another computer or mobile device from one computer or mobile device.

These applications usually use passwords for authentication to ensure that only authorized users can access the device. Once the connection is successful, users can access another device in the remote desktop client, including viewing and manipulating files, sending text messages, making phone calls and so on.

However, it should be noted that using these applications for remote control may have security risks. If unauthorized people can obtain passwords or other access credentials, they may access users' devices and perform malicious activities. Therefore, before using these applications, users should ensure that they have installed the latest security updates and use strong passwords to protect their devices.
