Amazon is developing Vega OS, a Linux-based operating system to replace Fire OS across its smart home lineup.
The first Vega OS device, a TV streaming device, is expected to be released later this year.
Vega OS uses React Native instead of Kotlin, requiring developers to rebuild their software.
While Amazon plans to include Vega OS in future Fire TVs and Echo smart speakers, it may pose challenges for power users who use third-party or Android applications.
