Android 12 on Xiaomi: what is new in the interface and functionality

With the release of the new operating system from Google, owners of Xiaomi smartphones are wondering what changes the update will bring. Android 12 has become one of the most ambitious visual updates in recent years, affecting almost all aspects of interaction with the device. For users of the MIUI ecosystem, this means not just changing the numbers in the firmware name, but also a deep reworking of the logic of the system.

The introduction of a new rendering engine and the change in the security architecture were key for shell developers, and while the changes were more cosmetic in nature, now the system processes that control memory and background applications are affected, this is especially important for devices with limited RAM, since the resource allocation algorithms have been rewritten from scratch.

Users who are waiting for the update will have access to a new design language that makes the interface more responsive.The system itself analyzes the color gamut of your wallpaper and offers the appropriate themes for widgets and menus.This creates a sense of a single digital space where each element looks organic.

Visual Revolution: Material You and Customization

The main visual innovation is the Material You concept, which dramatically changes the way we personalize. Unlike previous versions, where the themes were static sets of colors, now the system dynamically generates a palette based on the dominant colors of your wallpaper. This means that the settings menu, the notification bar and even the keyboard will automatically adjust to your taste. On Xiaomi devices, this feature is integrated into the MIUI 13 theme, creating a unique visual style.

The interface has become larger and more convenient to manage with one hand, headers have become more massive, controls have been rounded, and animations have acquired physical authenticity. When you scroll through lists or open applications, you feel inertia, which makes interaction with the screen more natural. Adaptive colors extend not only to system applications, but are also supported by many third-party programs, if developers have added appropriate API support.

The focus is on widgets that can now be stretched and combined to create an informative desktop, you can combine calendar, weather and task list into a single block, saving space on the screen, and for minimalist fans, this is a great opportunity to clean the interface of unnecessary visual noise.

It’s worth noting that the introduction of new graphics has required optimizing the GPU. On older Redmi or Poco models, visual effects can be simplified to maintain performance. However, basic design principles are retained on all devices receiving the upgrade, providing a single experience.

Data privacy and security

In the digital age, privacy is coming to the fore, and Android 12 offers powerful access control tools. The Privacy Dashboard is the centerpiece of the new security system, which gives users a clear timeline that tells them which apps and when they accessed a microphone, camera or geolocation, and you no longer know why the battery is running out, but what the sensors are actually doing.

⚠️ Warning: If you notice frequent access requests from an unknown app in the privacy panel, check its permissions in settings immediately or delete it.

Added new indicators in the top right corner of the screen that light up in green or orange when the camera or microphone is activated, which instantly signals that an app is recording. On Xiaomi smartphones, these indicators are harmoniously inscribed in the status bar and do not overlap the content. It also allows you to share only approximate location instead of exact coordinates, which is extremely useful for applications with weather or news.

Another important addition is the "Blocking permissions of unused applications" mode, which automatically revokes sensitive permissions from programs you haven't used in months, which reduces the risk of data leakage if an application is hacked or contains malicious code, and the microphone and camera can be completely disabled at the system level by a single switch, which guarantees absolute privacy at the right time.

💡

Check the Privacy Panel regularly in your security settings to identify apps that request access to your data without an obvious need.

Improvements in Notification Management and Exchange Buffer

Notifications have become more intelligent and less intrusive. The new priority system allows you to separate messages into important and background messages, hiding less significant alerts into a separate folder. You can quickly switch between tabs without losing important messages from messengers while advertising spam is hidden from view. On MIUI devices, this is complemented by smart filters that are trained based on your actions.

The big change was the clipboard, where applications could read copy text in the background without the user knowing, which put passwords and confirmation codes at risk. Now every time you access the clipboard, the system shows a pop-up notification. You always know which app and when it copied your text. This buffer control is critical to financial security.

• 🔒 Instant notification when any application accesses the clipboard.
• 📉 Automatic buffer cleaning after a certain time to protect data.
• 👁️ Visual indicator in the status bar with active access.

And also, faster settings are better controlled, the tiles are bigger, you can adjust them flexibly, and some of them have added features with prolonged pressing, for example, a long-term tap on the tiles can immediately open brightness settings without going deep into the menu, which saves time and makes smartphone use more efficient.

Productivity and energy efficiency optimization

One of the main goals of the update was to increase overall responsiveness of the system. Rewritten framework System Server allowed to speed up the launch of applications and switching between them. On Xiaomi smartphones with Snapdragon and MediaTek processors, this translates into a noticeable reduction in delays when entering text and scrolling pages. Optimization has also touched on the work with RAM, which allows you to keep more applications active in the background.

Energy consumption has also been revised. New algorithms limit the background activity of applications that are not currently in use. This is especially noticeable on devices with capacious batteries, where battery life can increase by 15-20%. The system learns your usage habits and prepares the necessary resources in advance, minimizing the idleness of the processor. The adaptive battery now works more aggressively and accurately.

There’s also good news for gamers: improved graphics and reduced input lag, faster launches, and lower frame drops in heavy scenes, thanks to an improved task scheduler, but it’s worth considering that on older models, some visuals may be disabled by default to keep things running smoothly.

Compatibility of Xiaomi and Redmi devices

Not all devices will receive an update at the same time. flagship models of the Mi and Xiaomi series (for example, Mi 11, Mi 10) were the first to get a new shell MIUI 13 based on Android 12. The middle segment, represented by the Redmi Note and Poco F series, receives a wave update, depending on the region and specific modification. Budget models can remain on the previous version of Android or get stripped down functionality.

The process of updating depends on the type of firmware (Global, EEA, China). Global versions often come out later than Chinese ones, as they require additional localization and certification by Google. Users of custom firmware (Global ROM on Chinese versions) should be careful, as automatic air update (OTA) may not be available or lead to errors.

It is recommended to check for updates regularly in the Settings menu → About Phone → MIUI version. If the update does not come automatically, you can use the “Check for Updates” function by clicking several times on the MIUI logo to activate manual check.

Known problems and ways to solve them

Like any major update, the transition to Android 12 can come with a number of technical issues. Users report periodic crashes in autobrightness and unstable Bluetooth headphone connection. Often these problems are associated with a conflict between old settings data and new system files. Resetting network settings or cleaning the cache of system services often helps to troubleshoot problems.

⚠️ Warning: Before installing a major update, be sure to make a full backup of important data to a cloud service or computer, as the installation process may result in loss of information.

Another common problem is increased battery consumption in the first days after the upgrade: the system indexes files and optimizes applications in the background, which puts a strain on the processor. Usually after 3-5 days of use, the situation stabilizes and the consumption returns to normal. If the problem persists longer, it is worth checking the battery usage statistics and removing the problematic applications.

💡

Stable system performance after a major update often requires a 3-5 day adaptation period for application background optimization.

In some cases, a full reset to factory settings (Wipe Data) may be required, especially if you are upgrading from a very old version of Android.This is guaranteed to eliminate software conflicts, but takes time to reset the device. To perform the reset, go to Settings → Advanced Settings → Recovery and Reset.
