The Xiaomi Mi Mix 2S was part of the Android Pie beta program, and Xiaomi is testing an alpha build of Android Pie for it. Other Xiaomi smartphones probably won't receive Android Pie updates for months, but users interested in trying out AOSP can use Android Pie today. This week we saw the Qualcomm variant of the Xiaomi Redmi Note 4 receive a stable Android Pie port with everything working. Xiaomi phones have a thriving development community on XDA, so it's no surprise to see that the Xiaomi Mi 3/Xiaomi Mi 4 and the Xiaomi Redmi 4X have also received stable Android Pie ports.
