Personalizing the smartphone interface starts with choosing the right background to set the tone for the entire visual part of the system. Owners of Xiaomi, Redmi and POCO devices often look for a quick way to replace a standard image with a personal photo or downloaded art. This process seems elementary, but the shells of MIUI and the new HyperOS have their own nuances that are worth knowing.
Using the built-in Gallery app is the most direct and convenient method of installing static or live wallpaper. You do not need to search for complex settings in the depth of the menu or download third-party launchers. Simply open the desired image, and the system itself will offer the necessary tools for editing and installation.
In this guide, we will take a closer look at all the steps of the process, and we will also look at the hidden features that allow you to adapt the picture to the screen with a cutout or dynamic island. You will learn how to properly crop images and avoid common errors that can spoil the appearance of the desktop.
Image Preparation and Format Requirements
Before you start installing, it is important to make sure that the image you choose matches the technical parameters of your display. Modern Xiaomi smartphones have high-resolution screens, so low-quality images will look blurry and unaesthetic. The optimal solution is to use source materials at a resolution of at least 1080×2400 pixels.
The file format also plays a role: the system works best with JPG and PNG formats. If you plan to install live wallpaper, the format may differ, but for a static picture from the gallery, these two options are standard. Heavy files in RAW or TIFF format can take a long time to process the system when applied.
- 📸 Choose vertical photos as they perfectly fill the lock screen and desktop without strong cropping.
- 🎨 Pay attention to contrast: too bright or colorful images can interfere with reading the text of widgets and icons.
- ⚖️ The aspect ratio should match your screen to avoid black stripes or unwanted zooming.
⚠️ Note: If you use the “Always on screen” function» (AOD), Make sure the bottom of the image does not contain important details, as it may overlap with the system clock or date.
Also worth mentioning are Dynamic Island and camera cutouts, where if you have important objects in the upper center, they may be hidden by the interface elements when you install them, and in such cases, it is recommended to do a cropping in any photo editor beforehand, shifting the focus below.
Basic installation algorithm through the Gallery application
The easiest way to change the background is to use the standard algorithm built into the Gallery app, which works equally stable on older versions of MIUI 12/13/14 and the latest HyperOS. The action algorithm is unified for most models of the brand.
Open the Gallery app and find the folder where you save the image, which could be a Camera folder, Downloads, or any album you create, tap the thumbnails to open the full screen.
☑️ Pre-installing check
When you open the image, look at the bottom of the screen or the option menu, which is indicated by three dots. In the list that opens, you need to find and click on Set as Wallpaper. The system automatically goes to preview mode, where you will see the picture lie down on the desktop.
You'll then have to choose between putting the image on the lock screen, on the desktop, or on both screens at the same time, and the newer versions of the shell also offer the ability to adjust the depth effect if the object in the photo is partially overlapped by hours.
Configuring the display and framing the picture
Once you select the target screen, the system will suggest you adjust the display, which is a critical step, because the original resolution of the photo rarely matches the resolution of the smartphone matrix one-to-one, and you will be asked to move the image and zoom in.
Use two fingers to zoom (approach or delete) and move the image in the right direction. Try to position the main object of the composition so that it does not overlap with app icons or the watch widget. HyperOS has a real-time preview, which simplifies the task.
- 🔍 Close the image to remove the extra edges if the photo is horizontal.
- 📐 Watch out for the grid that may appear when editing to align the horizon.
- 🔄 If the photo does not fit in proportions, it is better to choose the central fragment than leave empty fields.
Special attention should be paid to the Blur function (blur) In some themes and firmware versions, you can separately configure the blur for the lock screen to make the icons read better. If this option is not on the menu, you can pre-blur the edges of the photo in a third-party editor.
💡
Use the Preview feature before the final confirmation to see how the wallpaper will look along with the icons of your current theme.
When you finish setting, click the confirmation button, which is usually located in the lower right corner and marked with a tick or a nude Apply. The image will immediately take its place, and you will be able to evaluate the result.
Features of installation in MIUI 14 and HyperOS
Owners of devices that upgraded to MIUI 14 or HyperOS have noticed changes in their multimedia algorithms, and the shell has become smarter at analyzing the content of the photo and offering automatic improvements, such as offering to crop the photo to the Photos widget format.
HyperOS has improved its work with live wallpaper and super wallpaper. If you choose a video file from a gallery (in supported formats), the system can suggest converting it to a live background. However, for static images from a gallery, the process remained classic, but with smoother transition animation.
| Function | MIUI 12-13 | MIUI 14 | HyperOS |
|---|---|---|---|
| Automatic framing | Basic | Improved. | Intellectual |
| The depth effect | No. | Partially. | Full support |
| Live photos from the Gallery | Limited. | Support | Expanded |
| Speed of application | Standard. | Tall. | Instant. |
The new versions also offer a more flexible style setting for the lock screen, which can now interact with objects in the background. If the photo is high-quality and has a clear foreground, the system will suggest separating it from the background to create a parallax effect.
Installation of live wallpaper and video backgrounds
Many users want to see not just a picture, but a video clip. Xiaomi's standard gallery allows you to install video as live wallpaper, but with some limitations. The file must be short and optimized so that you don't overcharge your battery.
The process is similar to a static photo, where you open the video in the gallery, click on the menu, and select Set as wallpaper, and the system will warn you of a possible increase in power consumption, which is a standard warning for all Android smartphones, because the constant decoding of the video requires the resources of the processor.
⚠️ Attention: Installation of heavy video files (4K, 60 FPS) as a live wallpaper can lead to a noticeable decrease in the autonomy of the device and heating the case in pocket mode.
For better performance, it is recommended to use specially optimized live wallpaper from Themes store, rather than arbitrary videos from the gallery.However, if you want a specific snippet from a personal video, the method through the gallery remains the only quick solution without root rights.

Solving problems and application errors
Sometimes users are faced with a situation where the installation button is inactive or the image is used incorrectly, most often due to the permissions of the Gallery application to the system settings or damage to the theme cache.
If you click on Install as Wallpaper Nothing Happens, check the permissions of the application. Go to Settings → Apps → All Apps → Gallery → Rights and make sure that you allow you to change the system settings. In some cases, cleaning the theme cache through the Themes app helps.
- ❌ Format error: If the file is not supported, convert it to JPG through any online service.
- 🔒 Change protection: Make sure your phone doesn’t have Guest mode on or strict parental controls restrictions.
- 💾 Memory Lack: With overcrowded storage, the system may not be able to create a wallpaper preview.
Another common problem is low compression quality. The system can make the image stronger when installed. To avoid this, use images with a margin of resolution. It is critical to understand that 4K wallpaper will be compressed to the physical resolution of your screen, so uploading 8K photos does not make sense.
💡
If the standard method doesn’t work, try first installing the picture through the Topics app in the Local section, and then applying it from there.
