The Voltra TV v9 download is an Android APK with a minimum requirement of Android 6.0. Many Fire TV products run Android-based Fire OS, but Amazon now also sells Vega OS models that do not use Android APKs. The exact generation matters more than the marketing name alone.
Compatibility information below is based on Amazon’s published device specifications as of August 5, 2026. It describes operating-system fit, not a guarantee for every firmware revision or hardware configuration. Voltra TV is not affiliated with Amazon.

Why Fire OS models can use Android APKs
Amazon’s Fire OS overview describes Fire OS as a fork of Android. Fire OS 8 is based on Android 10 and Android 11, while Fire OS 7 is based on Android 9. Voltra’s APK is intended for Android 6.0 and later, so those bases clear the minimum version requirement.
Version fit is only the first check. Fire TV hardware, Amazon services, storage and firmware differ from standard Android TV devices. Remote navigation, playback and installation should still be verified on the exact model.
Why Vega OS models are excluded
Vega OS is not an Android target. On Amazon’s device table, the Fire TV Stick 4K Select (2025) and Fire TV Stick HD (2026) have no Android API level because they run Vega OS 1.1. The Voltra file is an Android APK, so the Downloader instructions are not appropriate for those products.
This is especially important for searches around “Voltra TV on Fire TV Stick HD.” The Fire TV Stick HD with Alexa Voice Remote released in 2024 is listed with Fire OS 7, while the Fire TV Stick HD released in 2026 is listed with Vega OS. Check the year and operating system before downloading.
How to identify the exact device
- Open the Fire TV device information or About screen.
- Record the full model name, generation and release year if shown.
- Confirm whether the operating system is Fire OS or Vega OS.
- For Fire OS, compare the Android base with Voltra’s Android 6.0 minimum.
- Use only the official Voltra Fire TV installation guide and APK from voltra.tv.
Fire OS 7 and 8
These versions are based on Android releases above Voltra’s minimum, though model-level testing remains important.
Vega OS 1.1
The current Voltra Android APK does not apply to Vega OS devices.
What about other Fire TV generations?
Some earlier Fire OS 6 and 7 devices can meet the Android-version floor, but memory, storage and firmware vary. Fire OS 5 is based on Android 5.1, below Voltra’s Android 6.0 requirement. When a model is not in the table above, check Amazon’s official specification page rather than inferring compatibility from the Fire TV name.
