Amazon’s latest streaming device — the Fire TV Stick 4K Select — has just launched, and at first glance it looks like a smaller, cheaper version of the popular 4K Max.

But under the hood, it’s something entirely different. This stick runs on Vega OS, a new operating system developed in-house by Amazon that fundamentally changes how Fire TV works.

The biggest difference? No sideloading.
Vega OS is a closed system that only allows apps from the Amazon Appstore — and for many users, that’s a deal-breaker.

Here’s what Vega OS is, how it compares to Fire OS, and why you should avoid the 4K Select if you use any advanced apps, players or custom tools.

What Is Vega OS?

Vega OS is Amazon’s new Linux-based operating system designed to replace Fire OS, which was built on Android.

Unlike Fire OS, Vega OS does not support Android APK files, and it completely removes the option to “Install unknown apps.”

That means:

• No Downloader app.

• No third-party file managers.

• No sideloading of any APK whatsoever.

• Only Appstore apps can be installed and run.

At launch, even VPN apps were missing from the store — though Amazon has indicated they will add them later.

Why This Matters for Streamers

For casual viewers using Prime Video or Netflix, Vega OS will feel no different.
But for those who rely on custom setups — TiviMate, IPTV Smarters, Analiti, DNS Changers, network diagnostic apps — this device is a dead end.

With no APK support and no file access, you can’t add tools that improve connection speed, fix buffering, or analyze your network.

The Fire TV Stick 4K Select is effectively Amazon’s first “locked” streaming stick — part of its move toward a controlled, Appstore-only ecosystem.

Key Differences vs Fire OS Devices

Why You Should Avoid the 4K Select

• 🚫 No sideloading of any kind — so you can’t install custom apps or network tools.

• 🔒 Locked ecosystem — only Amazon-approved apps will run.

• 🐢 Limited control — no way to manage cache, logs, or system processes through file managers.

• 🧩 App availability issues — many apps that exist on Android Fire OS don’t yet exist on Vega OS.

• ⚠️ Future compatibility unclear — Amazon may move all new devices to Vega OS in 2026.

For advanced users who like to tune, optimize, or test their devices, this stick removes nearly every option that made Fire TV popular in the first place.

Who It’s Still Good For

If you only use Fire TV for:

• Amazon Prime Video

• Netflix, Disney+, YouTube, BBC iPlayer

• Music and basic apps

Then Vega OS will work perfectly. It’s simple, secure, and budget-friendly.

But if you value flexibility, customization, or advanced streaming apps, the Fire TV Stick 4K Select is not the right choice.

Our Recommendation

Stick with older Fire OS models for now — specifically the Fire TV Stick 4K Max or 4K (2023 edition).
These models still support sideloading and developer options, and are compatible with tools like Analiti, DNS Changer, and custom media players.

Avoid the 4K Select until Amazon confirms full VPN support and clarifies whether future firmware will allow user control.

Final Thoughts

The Fire TV Stick 4K Select marks a clear shift in Amazon’s strategy — from an open, Android-based ecosystem to a closed, curated one.
For everyday viewers, that’s fine. For advanced streamers, it’s a major step backwards.

If you enjoy fine-tuning your setup, testing network performance, and installing apps that Amazon doesn’t offer in the Appstore, the 4K Select simply isn’t for you.
Choose Fire OS models while they’re still available — or consider an Android TV box for maximum freedom and performance.
