Fire TV Stick 4K Max Review 2026: the last ‘open’ Fire TV Stick

Fire OS or Vega OS: why this is the last ‘open’ stick

Amazon is replacing Fire OS, which is based on Android, with Vega OS, its own Linux-based system. Vega OS only runs apps from Amazon's own app store and you can no longer install anything yourself. For IPTV viewers that is a big difference: TiviMate and other Android apps don't work on it.

The Fire TV Stick 4K Select, the 2026 Fire TV Stick HD and the new third-generation Fire TV Stick 4K all run Vega OS. The second-generation 4K Max is the last stick to keep Fire OS 8. According to AFTVnews, existing Fire OS devices won't be converted to Vega OS, and Amazon promises security updates for at least four years after the stick was last on sale.

One caveat: since late 2025 Amazon has blocked apps that are on an anti-piracy list, even if you installed them yourself. Amazon doesn't publish which apps are on that list. In September 2026 a settings bug briefly broke sideloading on some sticks; Amazon fixed it within a few days.

Picture and sound

The stick plays 4K at 60 frames per second and supports all HDR formats: Dolby Vision for TVs from LG, Philips and Sony, among others, HDR10+ for Samsung and HLG for live broadcasts. That gets you the best picture from Netflix, Disney+ and Prime Video on almost any 4K TV.

For sound there is Dolby Atmos and 7.1 surround, and over HDMI ARC the stick passes the sound on to a soundbar or receiver. It also decodes AV1, the video format that streaming services use more and more. That makes it ready for the years ahead.

Wi-Fi 6E, but no network port

The stick has no network port. Amazon sells a separate adapter that you plug into the micro-USB port, but it manages 100 Mbit/s at most. That is enough for one 4K stream, which usually needs 15 to 25 Mbit/s.

In practice Wi-Fi is often the better choice: the stick has Wi-Fi 6E, so it can also use the 6 GHz band, provided your router supports it. If the router is far away or you live in a busy block of flats, choose the 5 or 6 GHz band or the adapter.

Speed and everyday use

The MediaTek chip with four cores up to 2.0 GHz makes menus and apps noticeably faster than on the standard Fire TV Stick 4K. With 16 GB of storage there is enough room for an IPTV app, a few streaming services and the TV guide cache. The 2 GB of RAM is the limit, though: a channel list with thousands of channels loads more slowly than on a box with 3 or 4 GB.

The home screen revolves around Amazon: you see a lot of advertising and recommendations from Prime Video. If you mainly watch IPTV you won't notice much, because you put the IPTV app at the top as a favourite. The Alexa Voice Remote Enhanced also controls the volume and power button of your TV and has buttons for live TV.
