Earlier this year Xiaomi released the first Android 8.1 Oreo-based MIUI 10 Global Beta ROM for the POCO F1. The company has been releasing weekly Global Beta builds, and the most recent being MIUI 10 Global Beta 8.10.25. After its announcement alongside the Mi 8 lineup, Xiaomi had started rolling out the MIUI 10 Global Stable update for many of its phones. Last week the company announced that wait would finally end as the MIUI 10 Global Stable update for the phone would be rolled out this week. Today, the POCO team has tweeted that the MIUI 10 Global Stable 10.0.4.0 update has started rolling out for POCO F1 users.

POCO fans! #DiwaliwithMi just keeps getting better. We have started rolling out MIUI 10 stable for #POCOF1 to all users. It's time to update!
