The Xiaomi Redmi Note 8 and Redmi Note 8T are now receiving new updates. No, the updates don't bring Android 10 to the phones, but that isn't far away either as Xiaomi is expected to begin the Android 10 rollout after fixing the bugs it discovered in an early firmware.

I have 11.0.9.0 PCXEUXM installed on redmi note 8T since last month. The think that I don't understand is that my daughter's phone that is the same Redmi note 8T gets 11.0.7.0. This article may be a little outdated, but neither of the two newer roms are Android 10 based.
