Personalizing the smartphone interface is the first step that a new owner takes, wanting to distinguish their Xiaomi Redmi from thousands of other devices. The lock screen is the very business card that you see every time you pick up a gadget, so the desire to see a really high-quality and pleasing image is absolutely natural. Unlike standard stock Android shells, MIUI firmware and its successor HyperOS offer advanced customization capabilities that go far beyond simply replacing a static image.
In this article, we will discuss in detail all the available ways to install a picture on the lock screen Xiaomi Redmi, including hidden features and nuances of working with system limitations. You will learn why sometimes the selected photo does not display correctly, how to set up automatic image change and what file formats the system supports without loss of quality. Deep configuration of the appearance can radically change the perception of the device, making interaction with it more comfortable.
The process of changing wallpaper on Redmi Note, Redmi 13 or older Redmi 9 series models may have small visual differences in the menu, but the logic of the work remains the same throughout the ecosystem. We will look at both standard methods through Gallery and Settings, and advanced options for using the theme to get a unique result. It is important to understand that screen resolution and image proportions play a critical role in the final result.
Standard Procedure through the System Gallery
The most obvious and frequently used method of setting an image is to work directly through the Gallery app, which is ideal if you already have a saved photo that you want to see when you unlock it. The algorithm is simple: open the desired image, click on the More button (usually three dots or a gear), and select the "Install as wallpaper" option, and the system will suggest select the framing area, which is especially important for vertical shots.
Once you select the area, you'll see a menu with three options on the screen: Lock screen, Desktop or Both screens. We'll have to choose the first option for our task, but we'll have to consider that when you install through the gallery, the system can automatically use parallax or a slight zoom to ensure that the animation is smooth when you unlock it, and if you want to see a photo one-on-one without cutting edges, you need to control this moment at the framing stage.
Sometimes users are faced with a situation when the photo looks blurry or with compression artifacts after installation. This happens if the original image is too low resolution or non-standard format. The optimal solution is to use JPG or PNG files with a resolution of at least 1080×2400 pixels for modern models. The quality of the source directly affects how the image will look on the AMOLED or IPS matrix of your smartphone.
💡
Use 9:16 or 9:19 aspect ratio images to avoid black stripes or heavy edge trimming on camera-cut screens.
Importantly, some versions of MIUI may activate wallpaper carousel when installed through the gallery, even if you didn't plan to. It's a system feature that tries to diversify your experience by uploading content from the Internet. If your goal is a static picture, make sure that the theme or wallpaper settings turn it off, otherwise your photo may be replaced with advertising content after a while.
Setting up through the menu Themes and Wallpaper
A more flexible visual style management tool is in the Themes system app, and that's where the screen fine-tuning capabilities are concentrated. Going to Profile (the person icon in the corner) and selecting Wallpaper, you're taken to the control center, where you can configure the lock screen and the desktop separately, a method that's preferred because it gives you more control over the process.
Inside the wallpaper section, you'll find not only pre-installed collections, but also the ability to download your image from the device's memory. By clicking on the + or Local icon, you choose a photo from the gallery. The advantage of this path is that there are often additional filters and effects that you can apply to the image before installation. It's also easier to manage the display order if you decide to create a slide show from multiple photos.
- 🖼️ Local Wallpaper: Allows you to select any photo from your internal memory or SD-maps without source restrictions.
- 🌐 Online Collections: A Huge Base HD-Images sorted by category (nature, abstraction, cars) that are optimized for Xiaomi screens.
- 🔄 Dynamic Wallpaper: A special type of content that can vary depending on the time of day or user actions, although it consumes more battery power.
The video wallpaper section, which is also available on this menu, is worth noting. Although it's not technically a static picture, many users are looking for a way to bring the lock screen to life through this feature. You can upload a short video or animation that will be played on a locked screen. It's worth remembering that using video wallpaper significantly increases energy consumption, so it's better to stay within static, high-quality images for daily use.
Use of the Wallpaper Carousel (Glance) function
One of the most talked-about features in the MIUI shell is the Wallpaper Carousel (known in some regions as Glance), a service that automatically changes images on the lock screen by downloading them from the Internet. For many users, it is a desirable feature that allows you to constantly see new content, but for others it becomes a source of irritation if you misconfigure it.
To activate or configure this mode, you need to go to Settings → Lock screen. Here you will find the wallpaper carousel switch. By turning it on, you can access advanced settings where you can choose the subject of images (sports, art, nature, technology). The system will update the picture itself every time you turn up on the screen. This is a great way to always have fresh visual content without unnecessary actions.
⚠️ Warning: Wallpaper carousel requires an active internet connection to upload new images. In roaming or with limited traffic, it is better to turn off this feature or configure the download only via Wi-Fi to avoid unnecessary costs.
If you like the idea of changing pictures, but don't like the intrusive content from Xiaomi, there's a workaround: You can create your own album in the gallery, fill it with your favorite photos, and then select the source "Local Album" in the carousel settings (if the firmware version allows), in which case the automatic change will only happen with your personal pictures, which guarantees no advertising and extraneous images.
Advanced customization and creation of slideshow
For users who want to have maximum control, you can create your own slideshow, which is not just randomly changing pictures, but a structured process, and you can assemble a collection of dozens of photos, like a family archive or a selection of motivational quotes, and adjust the intervals to change them, and this turns the lock screen into a digital photo frame.
To do this, go to the Themes app, select the Wallpaper section and find the "Create a Slideshow" option (the name may vary depending on the version of MIUI) and you will be asked to select an album from the gallery. Once selected, the system will suggest setting a timer: how often to change the image (every 5 minutes, every hour, with each unlock).
| Setup parameter | Recommended value | Impact on the system |
|---|---|---|
| Shift frequency | Every time you unlock. | Maximum variety, average processor resource consumption |
| Photo source | Local album | Traffic savings, no advertising, full control |
| File format | JPG (high quality) | The optimal balance between quality and the place occupied |
| Orientation | Portrait (9:16) | Perfect screen filling without distortion |
When creating a slideshow, it is important to consider that transitions between images can be animated. In the theme settings, you can often choose the type of transition: simple appearance, dissolution or shift. Using complex transition animations can put a strain on the GPU when you turn on the screen, which can theoretically lead to micro-latency in the system response on older Redmi models.
☑️ Checking before launching slideshow
Solving problems with display and quality
Often, users are faced with the fact that after installing a beautiful HD-Artifacts appear on the lock screen, stripes or colors appear faded, and this can be due to several factors: compression by the system, an incorrect color profile, or conflicting themes. If you notice that the black on the lock screen looks like dark gray, check if the screen settings include a “Paper” or “Read” mode that aggressively filters the colors.
Another common problem is shifting the image up or down, which causes an important part of the image to be lost (like the face in the portrait), which is due to the cutout under the front camera or sensors. The system automatically crops the image to avoid placing important elements under the bangs. To avoid this, use photo editing apps and add black fields at the top and bottom in advance, creating the illusion of correct framing.
⚠️ Warning: If the lock screen turns black or freezes after installing the theme or wallpaper, try restarting the device. 90% of the time, this is a software failure of the graphics shell cache, which is solved by a simple restart.
Also worth mentioning is the brightness problem. AMOLED-When you put very bright or white wallpaper on the lock screen, you can experience uneven backlighting or a dirty screen effect, which is a feature of the matrix at low brightness levels. In such cases, it is recommended to choose images with a predominance of dark tones or use a dark interface theme that harmoniously combines with such wallpapers.
The Effect of Third-Party Themes on the Lock Screen
MIUI theme store is a powerful tool that completely changes the way you look. However, when you install a third-party theme, you often change the design of the lock screen. Some themes have hard-wired wallpaper that can't be changed by standard methods without breaking the integrity of the design. In such cases, replacing the image through the Gallery can bring back the standard MIUI style, resetting the visual style of the the theme.
To set your picture while maintaining the theme style (like unusual watches or widgets), you need to look for themes marked “Customizable Lock Screen” or similar. The theme description usually indicates whether it supports replacing wallpaper by a user. If the theme does not support customization, the only way to put your photo is to abandon the the theme and return to the standard shell, or use third-party launchers, although they affect the desktop primarily.
The Secret to the Perfect Black
So in conclusion, it's safe and fun to experiment with the look, and you can always go back to the factory settings if you don't like it, and the key is to use good source materials and understand the logic of how the system works, so that the image on the lock screen is pleasing to the eye, not asking questions.
💡
The quality of the final image depends on the source file by 80%: always use the original photo in high resolution, not screenshots or photos from messengers.
