To use the video calling function on Android devices, you need to update the Telegram application in the Play Store to the latest version (7.0), open it, and then click the button with the camera icon in the user profile. The function allows you to switch between a voice call and a video call right during a call, as well as correspond in chats without ending the call: it can be minimized into a small window in the corner of the screen.

Telegram uses end-to-end encryption to protect video calls. To check the security of the connection, the service offers to compare four emoji that the user will see on his screen with the emoji that the interlocutor sees. If the characters match, the call is well protected by encryption, which is used for secret chats and voice calls.

In the future, Telegram is going to add new features to video calls. For example, adding the ability to conduct group video calls.
