No, I have Mix 2S but same Pie basedIs a MI 8 (Dipper) problem, you have a MI8 with working "Ok Google"?
Is a rom problem (Xiaomi) because if i install Havoc rom' or Pixel experience or LOS16, "Ok Google" works also on my MI8
Dosn't seems a Google problem, but a problem on Xiaomi MI8 rom.
I've already set my main language to US, Assistant language to US....... it works if i install a different rom.
On google support page there is a topic for MI8, it dosn't work for all MI8 regardless of region.....is a bug, something is missing.
