Why Xiaomi System Is Raising So Many Questions
When it comes to Xiaomi smartphones, one of the most common questions users ask is what operating system they are running on. The answer is not as simple as it seems: even within the same line of devices can use different shells and versions of Android. Some face MIUI on the Redmi Note 12, and some are surprised to find Android One on the Mi A3. And that’s not all: since 2023, the company has been actively migrating devices to the new HyperOS, which adds to the confusion.
In this article, we will look at what systems are installed on Xiaomi, Redmi and POCO smartphones, how they differ from each other, and how to determine which version works on your device, and how to change firmware to an alternative one, and what happens if you try to install a pure Android instead of a proprietary shell. Spoiler: not all experiments are successful.
If you're just planning a purchase or you're already experiencing unusual smartphone behavior, this information will help you avoid common mistakes, like why MIUI 14 might slow down on budget models, but HyperOS doesn't support some of the old shell features. Let's get straight.
1. MIUI: Xiaomi's proprietary shell with features
MIUI is a proprietary shell that Xiaomi has been developing on top of Android since 2010, known for its flashy design, rich features and... controversial solutions like aggressive background optimization. MIUI is by far the most common system on the brand’s devices, but it’s not the only one.
The main features of MIUI:

- 📱 Xiaomi Mi A3 (2019, Android 9.0 → 11.0)
Advantages of Android One:
- ✅ Quick security updates directly from Google.
- ✅ No unnecessary applications and aggressive optimization of background processes.
- ✅ Google Camera (GCam) support without any manipulation.
First, Xiaomi often saved on hardware for the Mi A line, so even the Mi A3 with the Snapdragon 665 slowed down on Android 11. Second, after support ended, updates stopped forever - unlike MIUI, where sometimes unofficial firmware from enthusiasts comes out.

3. HyperOS: A New Era for Xiaomi (from 2023)
In October 2023, Xiaomi announced HyperOS, a new operating system that will replace MIUI on all devices of the brand.It is not just an updated shell, but a full-fledged ecosystem that combines smartphones, tablets, smartwatches and even Xiaomi SU7 electric cars.

| Design | Bright colors, round icons | Minimalism, flat design, adaptive themes |
| Productivity | Aggressive optimization (sometimes interferes) | More balanced management of resources |
| Support for devices | Smartphones and tablets only | All devices in the ecosystem (including IoT) |
| Updates | 2-4 years (depending on the model) | Longer (up to 5 years for flagships) |

However, the transition does not always go smoothly: users complain of bugs with notifications, the lack of some MIUI features (for example, Second Space) and problems with the compatibility of third-party launchers.
