Amazon is reportedly planning to stop using Android on future Fire TV Sticks, with the latest model running on Vega OS. However, it is unclear if this change will apply to all Fire TV devices or when it will take effect, as some outlets suggest the switch may not happen immediately or may not affect all models. The future operating system for Amazon's Fire TV line appears to be in transition, with possibilities including Vega OS, Linux, or a continued use of Android in some form.
