Xiaomi recently launched miui 10 based on Android 10 in India. The update is only pushed to the beta testers. This update has too many bugs and that is the reason of releasing this update secretly and xiaomi didn’t create any hype about this update.
This update is only released for closed beta team. We don’t recommend you to flash this rom to your device because it has too many bugs and critical issues in it but developers are solving these issues and you will expect the stable version of this rom will be released by xiaomi very soon. If you want to try it now the download link is provided blow.
