Overview
- Amazon’s developer documentation officially shows a forthcoming Fire OS 16 that incorporates Android 15 (API 35) and Android 16 (API 36) changes for Fire TV apps.
- The guidance lists concrete app changes including an edge-to-edge UI requirement, a new local network permission model, and altered back-button behavior that can stop the Fire TV remote from working in apps using the old onBackPressed() method.
- Amazon has not published a public rollout schedule or a list of devices that will receive the Android‑16–based Fire OS, leaving timing and device support unclear.
- Amazon is simultaneously rolling out VegaOS on some newer Fire TV sticks, so Android‑based Fire OS updates and the new VegaOS platform will coexist across different hardware lines.
- For developers this means updating apps to meet the new APIs to avoid breakage, and for users it could mean reduced sideloading and uneven update coverage depending on whether a device runs Fire OS or VegaOS.
