Discovery of the experimental Tamba app in YouTube Android code
Google’s YouTube platform appears to be working behind the scenes on building a new experimental social media app called Tamba. Code discovered in the latest version of the YouTube app for Android revealed code descriptions for a follower system, direct messages, group chats, and its own independent posts, according to an exclusive code teardown of the package file published by tech site Android Authority on November 4, 2026.
Google has not officially announced this project yet, and it remains unclear whether the Tamba project will turn into a standalone app, have its features integrated into the main YouTube app, or never reach users at all.
Hand-drawn visual identity and 38 custom icons inside a standalone package
Android Authority experts found the branding and visual identity for the Tamba app while examining version 21.44.534 of the YouTube app for Android. This branding is tied to a package named com.google.android.youtube.sandbox, which the YouTube codebase treats as a separate app with its own search suggestions and file providers.
The discovered logo shows the name “Tamba” in bold next to a hand-doodled art style with the iconic play button symbol cut out of the middle. The teardown also revealed 38 hand-drawn style icons, including home, search, camera, inbox, chat, stickers, and microphone icons.
Social network features and playing Shorts inside chats
Dozens of new notification types discovered in the code look like they belong directly to a full-fledged social network; users will be able to follow each other, send and approve follow requests, and exchange text, photos, and videos in one-on-one or group chats.
Users will also be able to heart posts, Shorts, and comments, and reply using a voice note or a short video clip. Other code strings indicate the ability to play Shorts directly inside chat windows, with separate pages for welcoming new users and activity history, while identifiers for Android Sandbox and iOS Sandbox suggest Google is testing versions for both systems.
Messaging feature testbed or standalone app to rival Instagram?
Several tech media outlets compared the discovered feature set to Instagram; however, Android Authority noted that the “Sandbox” naming suggests Tamba may be an experimental playground for social features rather than a final commercial product, as the code refers to the initiative as “Project Sandbox” and labels its icons as experimental. Notably, this is not just a standard internal test build because YouTube has a separate package dedicated to those builds.
This discovery comes as YouTube expands private messaging features within its main app, having hinted at incoming group chats. This means some Tamba features could end up inside YouTube itself. Android Authority concluded its report cautiously, emphasizing that because the features “are still buried in the app code and appear experimental, it is much too early to say when or if Tamba will reach users.”
Analytical look at the strategic and economic dimensions of the event
The code teardown of the latest YouTube Android app, which revealed the Tamba project and its standalone package featuring roughly 38 hand-drawn icons, highlights Google’s ongoing effort to bridge the interactive and social gap between its video platform and competing apps like Instagram and TikTok. Adding a complete system for followers and follow requests, individual and group chats, voice note and Shorts replies, and in-chat playback reflects a clear desire to keep users within the YouTube ecosystem when sharing and discussing visual content.
Whether the Tamba project—internally known as Project Sandbox—ends up becoming a standalone social app on Android and iOS, or its tested features gradually become a core part of the main YouTube app (which is already expanding private messaging), these code experiments confirm that the future of video platforms is no longer limited to broadcasting and passive viewing, but is moving strongly toward integrating short-form video with closed interactive chat rooms.
