The Pocophone F1 – known as POCO F1 in India – is receiving MIUI 10 stable update with February 2019 Android security patch.

This update carries version number 10.2.3.0.PEJMIXM and weighs more than 550 MB in size. We don’t know what else this update brings to the phone because the developer team “didn’t have time to write the full changelog“. But what we do know is that it doesn’t bring 4K 60 FPS video recording support that was rolled out through a beta update earlier this week.
However, Alvin Tse, who’s the Head of Pocophone Global, has said that the company will release another stable update later this month to bring 4K 60 FPS video recording to non-beta users.

In addition to 4K 60 FPS video recording, this update also lacks Widevine L1 support which was rolled out for beta users last month. So if you want these two features right away, you might want to switch from stable to beta channel.
