All devices launched by Xiaomi in India this year have all received the update to bring the devices to Android 8.1 Oreo; that is except for the Redmi 5 and Redmi 5A. Xiaomi launched the list of devices that are due to get the Pie update before the end of the year and this also included those still yet to get Oreo.

The Redmi 5A launched last year again with Android 7.1.2 and with Android Pie the latest stable version of software available for public consumption, attention turned to when the devices would get the Oreo update.

Earlier this month, we reported that both the Redmi 5 and Redmi 5A were receiving the Android 8.1 based MIUI 10 in the form of a beta release. It would appear that the beta testing has completed as the MIUI 10 Global ROM has started rolling out to the masses. The new update shows as MIUI Global Beta 8.11.23 and also brings the November 2018 security patch to both the devices along with the Android version upgrade. In addition, other devices such as the Redmi Note 5 Pro have also received the November security patch with the same update. It is worth noting that Xiaomi has also enabled anti-rollback with the release of the MIUI Global Beta 8.11.23 on the Redmi 5 and Redmi 5A so if you do update it is worth remembering this.
