Telegram developers have added several useful functions to the new beta version of the proprietary application.
Telegram 7.8 Beta users can now show their smartphone screen or broadcast video during group calls. To test the function, the chat should be called #vid. After that, the group settings will display options for configuring recording or screen sharing. The video will only be displayed to those users who also have the beta version of the app installed.
By the way, the developers have also added an animated chat background to Telegram 7.8 Beta. It changes color while typing messages. You can enable this feature in the application’s appearance settings. Unfortunately, it is not yet known when all these innovations will appear in the stable version of Telegram.
