[Mar 4, 2020]: Xiaomi has released Android 10 based MIUI China Beta ROM for Redmi Note 7 Pro users, do note that it might be closed Beta build.
[Jan 7, 2020]: Xiaomi announced Android 10 update roadmap for its devices back in June, but it was only limited to MIUI China ROM. The company rolled out Android 10 based MIUI 10 to Redmi K20 Pro users in India and China on 5th September, the day Google rolled out Android 10 to Pixel devices. Xiaomi is yet to roll out Android 10 update for its Android One series of devices, Mi A3, Mi A2, and Mi A2 Lite, but the company has started rolling out Android 10 based MIUI 11 update to Redmi K20 (Mi 9T).
Xiaomi has already completed MIUI 11 roll-out for all 27 supported devices and now the company has started rolling out Android 10 update to a few devices. The devices receiving Android 10 based MIUI 11 update are,
- Redmi Note 8 Pro
- Redmi Note 7
- Mi MIX 3
- Mi 9 SE
- Mi 8 SE
Note that the Android 10 update is in the testing phase and is being rolled out to MIUI China ROM users only as of now. The company did not share Android 10 update roadmap for MIUI Global ROM, but we can expect the devices launched in 2019 to receive Android 10 update since most of the devices launched in 2018 received Android 9.0 update.
Xiaomi terminated the MIUI Global Beta ROM program back in June last year, so Global ROM users might have to wait for a couple of months (or maybe even longer) to enjoy Android 10 on their devices. You can download the MIUI China ROM for their devices from the links given below and flash it using a custom recovery, if interested.
