Remix OS
Remix OS is a Linux-based operating system developed by Jide Technology that brings the Android experience to desktop PCs. Designed to run on standard x86 hardware, it provides a full Android environment with a desktop-style interface. The OS features a taskbar, multi-window support, and keyboard/mouse optimizations, enabling users to run Android apps in a traditional desktop workflow. Remix OS is largely compatible with Android apps, and users can install the Google Play Store and other official Google applications.
Thanks to its collaboration with the Android-x86 project, Remix OS supports standard x86 systems (BIOS only) as well as x64 computers with either BIOS or UEFI. Its interface combines elements from conventional desktop operating systems—such as windowed applications—with specialized tools like a touch mapping utility, allowing touch-based apps to be used effectively with a standard mouse and keyboard.
The last version (3.0.207) was released in November 2016.
