The Chinese giant's smartphone owners are eagerly awaiting the new version of its proprietary shell.MIUI 12 marks a landmark step in the development of the interface, offering a redesigned design, improved privacy and new animations. However, the process of distributing the update does not happen instantly for all devices at once, which often causes confusion among users.
There is a clear firmware hierarchy, depending on the CPU power, the region of sale and the type of version (Chinese or global). Xiaomi introduces innovations in stages, starting with flagship models and gradually descending to the budget segment. Understanding this logic will help you not panic if your device has not yet received a notification about the download.
In this article, we will discuss the rollout process, the technical aspects of the transition to a new system, and answer the question of when to wait for an update for your particular model. Official support for MIUI 12 for most global devices was completed in 2021, so the relevance of finding a stable version is critical for security today.
Stages of the MIUI 12 Update Distribution
Xiaomi’s software release process is divided into several key phases, each with its own time frame and target audience, and is always the first to be introduced to the beta program (MIUI Beta), which allows engineers to collect error reports and stabilize the code before mass release.
Once the beta cycle is closed, the stable version will start to be distributed, and it is important to distinguish between China ROM and Global ROM. The Chinese version of the firmware will be released earlier, as it does not require long-term Google certification and adaptation to international communication standards. The global version undergoes stricter quality control and legal review, which creates a delay of several weeks or even months.
The spread is undulating, with this year's flagships and last year's flagships getting upgraded, then the middle class, and last but not least budget devices, all of which are driven by the need to optimize the interface for different hardware configurations.
- 📱 Beta testers: access first, risk of encountering bugs is maximum.
- 🌏 China: The stable version is now available 2-4 week before global.
- 🌍 Global Market: Expecting full Google services adaptation and localization.
- 📉 Budget segment: Latest in line due to iron restrictions.
⚠️ Note: If you own a device that was released more than 3 years ago, you may have an official stable version. MIUI 12 may be minimal.The company is focusing resources on supporting newer chipsets.
Sometimes Xiaomi launches an update first in one country (for example, Indonesia or Russia) to check the load on the servers before opening access to the rest of the world, so users from different countries can receive notification at different times.
List of devices that received MIUI 12
To determine whether your gadget falls into the list of lucky, you can refer to the official documentation of the manufacturer. MIUI 12 covered a wide range of devices, including the Redmi brands and POCO, Those who have previously used stock Android or older versions of the shell.
The Mi 10 and Mi 9 flagship lineup were among the first to receive an update, with enough performance to ensure the heavy animations of the new shell work smoothly, and older models like the Mi 8 or Mi Mix 3 also received an update, but the functionality could be cut down for stability.
The Redmi Note series is particularly noteworthy, with popular models like the Note 8 and Note 9 becoming massive recipients of the update, which significantly extended their life cycle, but with some modifications (such as the Helio vs. Snapdragon versions), the timing may have been different.
| Series of devices | MIUI 12 status | Features of the transition |
|---|---|---|
| Mi 10 / Mi 10 Pro | Stable version | Full support for all functions |
| Mi 9 / Mi 9T Pro | Stable version | Small camera bugs are possible |
| Redmi Note 8/9 | Stable version | Cut down animation on weak chips |
| POCO F2 Pro | Stable version | Full compatibility |
It is important to note that the list may vary by region, and a model sold in Europe may have a different firmware code than a similar model for the Asian market, which affects the availability of updates.
Differences between China ROM and Global ROM
One of the main factors affecting the release date of the update is the type of firmware. China ROM is developed exclusively for the domestic market of China, it does not have Google services by default, there are Chinese software and specific features that are focused on the local user (for example, integration with local payment systems).
Global ROM is an adapted version for the rest of the world, and engineers need time to uninstall Chinese software, implement Google Play Services, translate the interface, and most importantly, obtain certificates of conformity in different countries, which creates a major lag between the release of the version in China and the rest of the world.
Can China ROM be installed on a global version?
Global users often follow Chinese forums to predict the release date, typically between 4 and 8 weeks between a release in China and the world, but in the case of MIUI 12, this gap has sometimes widened due to a global pandemic and the complexity of testing logistics.
In addition, in the Global ROM, some features can be cut or changed, such as the AI features in the camera or the voice assistant may work differently, and the global version is generally more stable as it undergoes a longer testing cycle.
How to Check and Install Update Manually
If you don't get an automatic notification, you don't have to rely on luck. There are several ways to check for a new version of MIUI 12 by force. The easiest and safest method is through the settings of the smartphone itself.
To do this, go to the Settings menu → About Phone → MIUI version. In the window that opens, click on the system logo or the “Check Updates” button. If the server sees your device and confirms compatibility, download will begin.
☑️ Checklist before update
There is also a method of manual installation via recovery. You can download the current service pack (Recovery). ROM) It's from an official website or a trusted resource like miui.com, and it has the.zip extension, and you have to put it in the root of your internal memory or folder. downloaded_rom.
Once you have placed the file, go back to the update menu, click on the three dots in the corner of the screen, and select "Select the update file." The system will check the integrity of the package and suggest you restart for installation.
⚠️ Note: When you manually install firmware, make sure that the version in the file is newer than the current one. Trying to install the older version (Downgrade) without special manipulations will lead to an error and the inability to boot the system.
Using third-party PC software like the Mi Flash Tool requires an unlocked bootloader, a more advanced method that allows not only updating but also completely reflashing the device, but it carries great risks for inexperienced users.
Possible problems after installation of MIUI 12
Switching to a new major version of the operating system is always stressful for the device. Even if Xiaomi does thorough testing, problems can surface in real conditions. One of the most common complaints about MIUI 12 was increased battery consumption in the early days.
This is due to the process of file optimization and data re-indexing in the background. Android and MIUI rebuild the app caches. Usually the situation normalizes after 3-5 days of active use. If the problem persists longer, you may need to reset.
Other common problems include:
- 🔋 Heat: Device can warm up more than usual due to new visuals.
- 📉 Performance: On older devices, the interface can slow down.
- 📸 Camera: Changes in photo processing algorithms may produce unusual results.
- 🔔 Notifications: New Notification Management System May Be Baffling.
💡
After a major upgrade, it is recommended to manually restart the device at least once, even if the system does not require it, which helps to get all system services running correctly.
In rare cases, a “bootloop” may occur, most often when the installation process is interrupted or the update files are damaged, and this will require recovery through Recovery or Fastboot mode.
Is it worth waiting for MIUI 12 on older devices?
The issue of supporting older devices is always a hot topic. MIUI 12 has become a demanding shell. Devices released before 2018 may formally receive an update, but it will not work. Xiaomi is trying to balance the desire to give users new functionality and the need to ensure smooth operation.
If your smartphone runs on Android 9 or lower and has less than 4GB of RAM, switching to MIUI 12 may not bring the expected joy. Visual improvements can be offset by interface lags. In such cases, it is often more rational to stay on a stable MIUI 11 or 12.5 if it is optimized better.
💡
The main criterion for a successful update is not only the presence of a firmware file, but also the compliance of the hardware power of the smartphone with the requirements of the new shell.
However, the security updates that come with newer versions of MIUI are a critical argument for. Even if the interface gets a little heavier, protecting your data from modern threats is worth it.
