The Pocophone F1 and the latest Poco M2 Pro are receiving performance and security updates staring today, but there's no sign of MIUI 12 for these devices yet. Poco F1 is already in Phase 2 of the MIUI 12 beta testing, so the stable bits should arrive sometime in August. Meanwhile, the Redmi K20 Indian variant is getting a wider rollout of stable MIUI 12 after having been in beta testing earlier this month.
