Xiaomi and Redmi smartphone owners often face the desire to personalize the device immediately after purchase. The lock screen and desktop are the first thing that the user sees, so quality image plays a crucial role here. The standard gallery offers a good choice, but many are looking for the same “super wallpaper” that was shown at the presentation of flagships or is available only in certain regions.
System system MIUI And her successor, HyperOS, hides a lot of graphics that don't show up in the standard selection menu, which can be parallax-effect live wallpapers, highly detailed ones. 3D-Using a simple, ultra-high-resolution, rare static imagery, understanding the structure of the file system and knowing proven sources, allows you to access this content without obtaining root rights.
In this article, we will explore all the legal and safe ways to expand your background library, learn how to activate features hidden from the eyes of the average user, and where to look for content that does not fall into global firmware versions. Deep customization of the interface begins with choosing the right visual style.
Built-in MIUI and HyperOS capabilities
The first place to look is the standard Themes app, which, although many people think of as an icon-changer, is a powerful wallpaper engine, and unlike a simple static image, you can find complex animations that respond to touch or time of day. You need to have a Mi Account and be logged in to access the advanced functionality.
Often, users are unaware that the lock screen settings have a separate section for Wallpaper Carousel, which is not just a change of pictures, but full-fledged multimedia content with video and interactive elements. To find truly unique options, you need to change the region in your phone settings. Switching to India or Indonesia often opens up access to exclusive packs that are not available to users from the CIS or Europe.
⚠️ Note: Change of region may temporarily affect the operation of some system applications, such as a browser or voice assistant.
The Super Wallpapers feature, which was originally introduced on the Xiaomi Mi 11, allows you to see a planet that is smoothly transformed into a map of the terrain when unlocked, is available not only on flagships, but also on many mid-range models if you activate the system components correctly. This sometimes requires installing a special plugin through the debugging menu or third-party launchers that simulate the system environment.
Search for Hidden System Resources
Android stores all graphics in special archives inside the system partition. On Xiaomi smartphones, these files often have the.mtz extension or are located in hidden folders with read-only permissions. To get to them, you will need a file manager with advanced rights, such as Total Commander or MT Manager, although a standard guide with hidden files enabled will suffice for simple copying.
The main array of graphics is located along the path /data/media/0/Android/data/com.android.thememanager. Here you can find cached images that are uploaded from the Internet. However, the more valuable prey are files inside the system APKs. By extracting resources from the Themes or Wallpaper app, you can find source materials in high resolution. This is especially true for those who want to install original wallpaper from the presentation of the phone but do not want to put a heavy theme app.
- 🔍 Use the.jpg or.png extension search in system folders by sorting files by size – the heaviest ones are usually originals.
- 📂 Look for folders with names that contain Wallpaper, Bg, or Resource.
- 💾 Copy the files found into the user directory before you try to open or edit them.
It's important to understand that direct editing of system files without a backup can lead to unstable interfaces. APK-Just renaming an archive doesn't always give the correct result, because resources can be compressed or encrypted with specific data. MIUI algorithm.

Sources of quality content on the network
When built-in capabilities are not enough, specialized resources come to the rescue. The Internet is full of image sites, but smartphones with AMOLED screens and high resolution need special quality files. A normal image from a search engine can look blurry or have compression artifacts. For Xiaomi devices, it is important to look for content with a resolution of at least 1080x2400 pixels, and for flagships – 1440p and above.
One of the best sources is the official MIUI forums and Telegram communities. Enthusiasts often cut original wallpapers from new versions of China firmware immediately after they are released. Also worth noting is the portable versions of Google Wallpaper, which contain exclusive satellite images and panoramas optimized for mobile displays. These collections are often updated and do not require heavy-duty apps.
| Type of resource | Permission | Format | Where to find |
|---|---|---|---|
| Standard MIUI | 1080 x 2400 | JPG/PNG | Annex Topics |
| Super Wallpapers | 2000 x 2000 (sphere) | PNG | System files |
| Google Wallpapers | 4000 x 4000 | JPG | Play Market/APK |
| Live Wallpapers | Dynamic. | MP4/XML | Third-party launchers |
When downloading files from unverified sources, always check them for viruses. Wallpaper files are safe on their own, but theme installers may contain ad modules. The safest way to use files with the.jpg or.png extension from official developer repositories is to use them.
Installation and activation of super wallpaper
Once the desired files are found, they must be installed correctly. Simply opening the image in the gallery and selecting the "On the lock screen" option is the basic method, but it does not always allow all the functions to be used. Activating live wallpapers or specific formats may require the file to use through the settings menu. Go to Settings → Lock screen → Wallpaper carousel or Settings → Wallpaper for choosing a static image.
☑️ Pre-installing check
If you downloaded the whole theme (mtz file), you can install it manually. To do this, place the file in the root of internal memory or in the MIUI/theme folder. Then in the Themes app, go to the profile (human icon) and select My Themes. If the file does not appear, try renaming the extension to.mtz (if it is different) or use a third-party theme installer that knows how to work with local files.
For live wallpapers, the process may be different. Some formats require a special engine or plugin. For example, parallax wallpapers often only work in conjunction with certain versions of the launcher, in which case the user is asked to install an additional viewer application that takes over the rendering of the graphics.
⚠️ Attention: Installing themes from unknown sources, especially modified (mod), can lead to advertising in the system or a malfunction in the interface.
Optimizing performance when using live wallpaper
Using complex graphics and animations inevitably affects power consumption. Live wallpaper consumes CPU and GPU resources even when the phone is in standby mode, albeit to a lesser extent than active applications. On older Xiaomi models, this can lead to a marked decrease in autonomy. So it's important to balance beauty and functionality.
To minimize battery impact, MIUI has built-in limiters. However, if you use third-party live wallpaper, control may be weaker. It is recommended to turn off live wallpaper if you have power saving mode. It is also worth considering that on IPS screens, black in live wallpaper does not save energy, unlike AMOLED matrixes, where black pixels are simply turned off.
- 🔋 Use static wallpaper with a predominance of black color for AMOLED screens to save charge.
- 📉 Turn off the live wallpaper if the battery level drops below 20%.
- ⚙️ Check in the battery settings whether the Wallpaper or Theme process consumes too many resources in the background.
💡
If the phone started to heat up after installing new wallpaper, try to lower the frame rate in the live background settings or go back to static.
Solving Frequent Display Problems
Not all super wallpapers that you find fit perfectly on the screen. A common problem is cropping images when important details go over the edges or are overlapped by widgets and clocks. To avoid this, use the preview function before the final application. In some cases, rotating the image or framing it in the built-in gallery editor before installation helps.
Another common difficulty is poor compression quality, which can automatically (compress) the image for performance, which leads to a ladder on the gradients, and to combat this, you can try to rename the file by adding the word hd to the title or use formats with less compression, and also helps to clear the cache of the application "Themes" before installing a new heavy file.
If the wallpaper doesn't apply and the system gives you an error, check access rights. The application may be denied access to memory. Go to Settings → Apps → All Apps → Topics → Rights and make sure that access to the storage is allowed. In rare cases, resetting the application's settings to the themes to the factory helps.
💡
The quality of the final image depends not only on the source, but also on the correct aspect ratio and file format compatible with your version of MIUI.
