Xiaomi Mi Mix 2S joined Mi 8 and received an update to Android P 9.0. The update is intended for this moment only for the Chinese development version. Then it will go to Chinese ROMU users, and only later to the Global version.
Xiaomi Mi Mix 2S has been updated to Android P 9.0
People with global software need to be patient, I think implementation will last at least 2 months. Traditionally, as with every entry regarding the software, I recommend the Xiaomi.eu portal, where we can find software that contains weekly updates.
Android P for people with Xiaomi.eu will be available any day, tests are underway. I thought it would be last Friday, but there were problems. Developers do not want users to get unstable software.
I hope that the tests will end positively by Friday.
