Many users confuse the Android version and the MIUI shell. For example, Redmi 9A came out with Android 10 and the MIUI 12 shell, but later received MIUI updates to MIUI 12.5 - without changing the Android version. This is an important nuance: Xiaomi often updates the interface, but not always the main OS.

Let me warn you right away, if you're looking for a way to install Android 11 on the Redmi 9A at any cost, there's no official way, but there are workarounds, from custom firmware to manually upgraded via Fastboot, but each of these methods has risks, which we'll talk about.

Android 11 support for Redmi 9A: What Xiaomi says

Xiaomi Redmi 9A was released in July 2020 with Android 10 preinstalled and MIUI 12. According to Xiaomi’s policy, budget models usually get one major Android upgrade — that is, switching from Android 10 to Android 11 would be a logical step.

In 2021, Xiaomi confirmed that the Redmi 9A would not receive Android 11 officially.

• 📱 Hardware restrictions: the smartphone is equipped with a processor MediaTek Helio G25 and only 2 GB of RAM in the basic version, which is not enough for the stable operation of the new OS.
• 💰 Budget segment: Xiaomi is focused on upgrading more expensive models (e.g. Redmi Note 10 or the Redmi Note). POCO X3).
• 🔄 Priority MIUI: Instead of updating Android, the company releases new versions of the shell (for example, MIUI 12.5 Enhanced) that run on the same Android 10 base.

However, some users have reported that Android 11 for Redmi 9A has been tested in regions like India or Indonesia, but these firmware have been unstable and quickly recalled, and there is no official release date (2026).

⚠️ Note: If you see online offers to download "official Android 11 for Redmi" 9A", Xiaomi didn't make this firmware for this model.
