Xiaomi Redmi 9C: What version of Android is used and how to update it?

In this article, we will understand which versions of the OS support Redmi 9C, how to check the current firmware and what to do if updates stop coming.

The smartphone was released in 2020 based on Android 10 with the proprietary shell MIUI 12. But over the years, the manufacturer has released several updates — some of them radically changed the operation of the device. It is important to understand that the Redmi 9C belongs to the budget segment, so the maximum possible version of Android for this model is Android 12 (Go Edition), and further updates from Google it will not receive. However, this does not mean that the smartphone has become useless: the right settings and optimization will help to prolong its life.

If you are just planning to buy or already own Redmi 9C, this article will help you understand the nuances of the firmware, learn about the hidden features of MIUI and avoid errors when updating.

Which Android version is installed on the Xiaomi Redmi 9C out of the box?

Xiaomi Redmi 9C went on sale with a pre-installed version of Android 10 and a shell MIUI 12. This was the standard configuration for budget models of the time. It is important to note that the device belongs to the Android Go line, a lightweight version of the operating system optimized for weak hardware configurations.

The Android Go version has a number of features:

• 📦 Lightweight versions of standard applications (Google Go, YouTube Go, Gmail Go).
• 🔄 Optimized RAM consumption (on Redmi) 9C Only 2-3 GB of RAM).
• 📶 Improved background process management to save battery power.
• 🛡️ Built-in tools for traffic control and data protection.

Despite the lighter firmware, MIUI 12 offered users full functionality: dark theme, navigation gestures, game mode and even some artificial intelligence features (such as smart text recognition in images), but due to the limitations of hardware, some animations and transitions worked less smoothly than on flagships.

⚠️ Note: If you are buying a Redmi 9C hand, be sure to check the Android version in the settings. Unscrupulous sellers can reset the smartphone to factory settings, which will cause it to display outdated firmware, although it actually supports more recent updates.

What happens if updates no longer arrive?

If your Redmi 9C is already running Android 12 (MIUI 13), but you want a more recent version of the OS, you have a few options:

1. Installing custom firmware (like LineageOS or Pixel Experience) will allow you to get Android 13/14, but will require unlocking the bootloader and may be unwarranted.
2. Use alternative launchers (such as Nova Launcher or Lawnchair) to visually update the interface.
3. Optimizing your current firmware: disabling unnecessary services, cleaning your cache, and using lightweight applications.

The most radical but effective way is to install custom software, but this is only suitable for advanced users, because it requires:

• 🔓 Unlock the bootloader through the Mi Unlock Tool.
• 🖥️ Installations TWRP Recovery (castom recavery).
• 📲 Compatible version firmware GSI-assemblage.

Before you start re-flashing, consider:

• ⚠️ Risk of "bricking" (conversion of a smartphone into a "brick").
• ⚠️ Loss of warranty (if it is still valid).
• ⚠️ Possible bugs in the camera, sensors or mobile network.

💡

If you're not sure about your skills, you'd better stay on the official firmware and optimize it. Castomic builds require deep knowledge and can lead to unstable device operation.
