Akhirnya setelah lama menunggu-nunggu, MIUI 9 Global Stable dirilis untuk Redmi Note 4/4x (MIDO). Sebelumnya MIUI 9 versi Global Developer sudah dirilis sejak bulan Agustus 2017 yang lalu. Agak lama juga sih jarak antara versi developer ke stable. Mungkin memperbaiki beberapa bug yang ada di versi developer.

Update bisa diunduh baik melalui di situsnya, melalui recovery (tidak memerlukan unlock bootloader) atau jika bootloader sudah diunlock bisa mengunduh versi fastbootnya dan menginstall melalui MiFlash.

Meskipun menggunakan MIUI 9, tetapi Redmi Note 4 (MIDO) ini hanya mendapatkan Android 7.0 saja, bukan 7.1.
