Many Fire TV Stick 4K owners were holding out hope that the new Fire TV interface update that started rolling out to their devices last week would bring with it an update from Fire OS 6 to Fire OS 7. Unfortunately, that’s not the case. When the new interface arrives on a Fire TV Stick 4K, it moves it from software version 18.104.22.168 to version 22.214.171.124, which keeps it on Fire OS 6.
The new Fire TV interface is independent of the Fire OS version on the device and does not require an upgrade to Fire OS 7, the latest version of Amazon’s operating system, to be compatible with the device. Fire OS 5, like on the 2nd-gen Fire TV Stick, Fire OS 6, like on the aforementioned Fire TV Stick 4K, and Fire OS 7 devices, like on the 2nd-gen Fire TV Cube and 3rd-gen Fire TV Stick, are all compatible with the new Fire TV interface. Based on the updates that have already reached devices, it seems safe to say that the new interface update will not change the base version of Fire OS that is currently on the device.
While there are numerous Fire TV models running Fire OS 5 and numerous Fire TV models running Fire OS 6, it seems like the Fire TV Stick 4K was the main one people were expecting to be upgraded to Fire OS 7. That’s likely because it is the only stand-alone model in Amazon’s current Fire TV lineup that is not running Fire OS 7. Amazon has given no indication that the Fire TV Stick 4K, or any Fire OS 6 device for that matter, will ever be updated to Fire OS 7.
Furthermore, we continue to see brand new Fire TV Edition television models being released with Fire OS 6, as recently as last month, so Amazon is clearly not treating Fire OS 6 as an outdated operating system.
