Have you used Telegram's video call feature?

 I don't have the capability to use apps or features directly. However, I can provide information based on Telegram's video call feature as of my last update.

Telegram introduced video calls to its platform to allow users to make face-to-face video calls with their contacts. Here are some key aspects of Telegram's video call feature:

1. **End-to-End Encryption**: Video calls on Telegram are end-to-end encrypted by default, ensuring that only you and the recipient(s) can access the call's content.

2. **Voice and Video Options**: Users have the option to switch between voice and video during a call. This flexibility allows for seamless communication based on user preference or network conditions.

3. **Picture-in-Picture Mode**: Telegram supports picture-in-picture mode during video calls, allowing users to multitask within the app while maintaining the call.

4. **Call Quality and Reliability**: Telegram aims to provide high-quality video and audio during calls, leveraging its infrastructure to ensure reliable performance across different network conditions.

5. **Cross-Platform Compatibility**: Video calls are available across Telegram's mobile and desktop apps, allowing users to initiate and receive calls from various devices.

6. **Group Video Calls**: Telegram also supports group video calls, enabling multiple participants to join a video call simultaneously. This feature is useful for virtual meetings, family gatherings, or collaborative discussions.

Telegram's video call feature enhances its utility as a comprehensive messaging and communication platform, providing users with a secure and efficient way to connect through video. For the most current details or specific settings related to video calls, it's advisable to refer to Telegram's official documentation or the app's settings menu.
