Telegram Beta has updated its Android media playback engine to ExoPlayer 2.19.1, bringing behind-the-scenes improvements to video and audio playback.

The update is expected to improve playback stability, streaming compatibility, seeking, and bug handling across different Android devices. Users may notice fewer media playback issues, although there are no major new features directly associated with this change.

(In short: Telegram is upgrading the technology behind its media player for a smoother and more reliable playback experience.)
