As usual, the latest software update for Xiaomi's Mi A1 comes with a few spam videos on YouTube that mention Android 10. Sadly, the patch comes on top of the old Android 9 core that will not get updated via the official channels. Luckily, those who want Android 10 can pick one of the good third-party choices available.

Me too. I'm waiting for Xiaomi to officially end its monthly security update for Mi A1 then I'll migrate to custom ROM.
