Xiaomi Mi 10T and 10T Pro launched with MIUI 12 on top of Android 10 but now, Xiaomi is releasing an update to bump up the underlying OS to Android 11.
Reports from users in India say that the rollout has already begun in their region. The build number is 126.96.36.199 RJDINXM and the patch itself is 2.8GB big. The OTA update also brings the January 2021 security patch.
Perhaps users outside of India would have to wait a couple of more days before the Android 11 update hits their units as well, but do drop us a line in the comments if you got it elsewhere.
