Fire TV Stick 4K Select and Fire TV Stick HD (2026)

These two sticks run Amazon Vega OS. They are not Fire OS, the ScreenTinker APK does not install, and they are not certified hardware.

Which sticks

Every other Fire TV Stick still in the shops (4K, 4K Max, Cube, the 2024 HD stick) runs Fire OS and uses the Android APK. If Downloader says the package is invalid, you have one of the two above.

What the Vega player is

An installed app, built from vega/ in the ScreenTinker source, that opens your server's /player page inside Vega's WebView. Playlists, zones, widgets, YouTube, schedules and the volume controls are the web player's. They are not a port of the Android app.

It does not reboot the stick, it cannot lock itself as the home screen, and it does not play RTSP. Transitions run. On Vega the captured frame is downscaled, because the binding limit is CMA (the decoder's DMA pool, about 236 MB on a 4K Select), not the 1 GB of RAM. A synced group does not pre-buffer the next clip: a second decoder is another CMA claim. Build and install steps are in docs/vega-player.md in the repository. One 4K Select has been run: it played, transitions looked right, then the process died. It is not certified, and the capture cap has not been re-measured on a stick.

Do not buy these for a sign

They are listed under not supported on purpose. A player existing in the source tree is not a test on the hardware. Use a Fire OS stick, an Android TV box, or a Raspberry Pi until that page changes.
