How to install a picture on the lock screen Xiaomi: the complete guide

Personalizing a smartphone interface is not just a way to stand out, but also an opportunity to make interaction with a gadget more intuitive and enjoyable. Owners of Xiaomi, Redmi and Poco devices often face the need to change the standard, boring image for something more personal, whether it is a photo of a family, a landscape or an abstraction. The lock screen is the first thing a user sees when a display is activated, so its visual design plays a key role in the overall perception of the system.

But the MIUI shell or the new HyperOS has its own customization features that can confuse the untrained user. Unlike pure Android, there are additional layers of control through the Themes app, as well as the wallpaper features that can intercept control of the display. Understanding these nuances will allow you to avoid setting conflicts and set the exact image you want to see.

In this article, we will discuss in detail all available methods for replacing the background lock, we will look at both standard system tools and the possibilities of customization through the theme store, and will also address optimization issues so that beautiful but heavy images do not affect the speed of the device or battery consumption.

Basic methods of replacement through system settings

The easiest and most obvious way to change a static image is to use the built-in Android settings menu, which is universal and works on most firmware versions without having to connect to the Internet or download additional components, you only need to store the desired resolution image in the gallery in advance.

To start, open the Settings menu and find the look section, which, depending on the version of the shell, can be called Wallpaper or inside the Lock Screen, where the system will offer a selection of pre-installed collections, but we're interested in downloading your own file, and if you click on the appropriate button, you'll be taken to the file manager or gallery.

When you select the right photo, the system will suggest you adjust the image to zoom in, shift the center of the composition. It is important to consider the aspect ratio of your screen so that the image does not crop up critical details. Once you confirm the choice, the system will ask you where to apply the changes: only on the lock screen, only on the desktop or both.

💡

Use images with at least a resolution 1080x2400 pixels for modern Xiaomi smartphones to avoid loss of quality and the appearance of “grain” on the smartphone AMOLED-display.

It is worth noting that on some global versions of firmware, the path may be slightly different, for example, in new HyperOS updates, the menu logic has become more linear, and access to the wallpaper is made into a separate widget on the desktop or in the long-tap menu of the empty area of the screen.

Using the "Themes" application for deep customization

Themes app store is the central hub for visual style management in Xiaomi devices, and it's where the most advanced settings are hidden, allowing you to not just put a picture, but also create a dynamic slideshow from your photos. This tool provides much more features than the standard settings menu.

Run the Themes app and go to the user profile, which is usually the little man icon in the bottom right corner, and you'll find the Wallpaper section, and inside you'll see the Wallpaper Carousel or Slideshow tab, and that's what allows you to turn the lock screen into a live gallery, and you can select specific albums from the phone's memory, and they'll automatically change every time you wake up.

• 🖼️ Flexible management: the ability to choose multiple albums at once, creating a mix of different categories of photos.
• ⏱️ Shift intervals: adjusting the refresh rate of images (each screen turn on or after a predetermined time interval).
• 🔒 Privacy Mode: the ability to hide the preview of images in notifications if the carousel is turned on.

However, the use of this method has its own peculiarities: the Wallpaper Carousel function requires permission to access data and can consume a little more CPU resources in the background. In addition, some users note that when the carousel is turned on, there may be delays when unlocking the fingerprint, although the latest versions of MIUI 14 and HyperOS this problem is almost eliminated.

If you want to install the whole theme, but leave your wallpaper, the Themes app has a feature called Mix, which allows you to combine elements: take icons from one theme, fonts from another, and leave your own lock wallpaper or choose from a huge online library.

Setting up wallpaper carousel and slideshow

The Wallpaper Carousel is the most popular way to use the lock screen on Xiaomi smartphones, which not only changes pictures, but can also upload content from the Internet, show news or facts if the corresponding options are activated in the service settings.

To fine-tune your settings, go to Settings → Wallpaper → Wallpaper Carousel. The "Enable Carousel" switch is available. The source settings below are: you can select only local photos or add online sources. It's critical to check the refresh rate settings so that the battery doesn't run out faster than usual due to constant network access and graphics processing.

There's a nuance about the orientation of the images, and if you upload vertical photos to the carousel, they'll look organic. Horizontal images will automatically zoom in, which sometimes leads to edges being darkened or unwanted framing. Sometimes you have a "Stretch" or "Fill" option in the carousel settings, which helps to correct this effect.

⚠️ Note: When the wallpaper carousel is activated, standard widgets on the lock screen (steps, weather, music) can change their position or become translucent so as not to overlap the content.

Also worth mentioning is the Smart Activation feature, which allows the screen to light up and change wallpaper when lifting the smartphone, even without pressing the power button. This is convenient, but requires a proximity sensor and a gyroscope, and may not be available on low-end entry-level Redmi models.

Working with live wallpaper and video backgrounds

Modern. AMOLED-Xiaomi smartphone screens are ideal for displaying live wallpapers, video files or animated scenes that move when touched or unlocked, and the installation of such wallpapers requires more care, as they affect energy consumption.

You can install the video to lock it through the Themes app by selecting the Live Wallpaper category. Many of them are free and optimized by the company's engineers. However, enthusiasts often want to put their own short video. Third-party applications are not always required for this: some versions of the shell when selecting photos from the gallery, a button appears "Install as a live wallpaper" if the file is in a supported format.

When using live wallpaper, the system can automatically limit their performance in power saving mode. On devices with Snapdragon 6 Series processors and below, the use of heavy 4K live wallpaper can cause micro-freezes of the interface.

Another important aspect is Always On Display (AOD). If you have a constantly running screen on, the live wallpaper on the main lock can conflict with it. Usually, AOD is given priority, and animations only start after the phone is removed from the lock or the AOD timer has expired.

Problems with the use of images and their solution

Often users are faced with a situation where everything seems to be done correctly, but the picture is not installed or displayed incorrectly. One common reason is a malfunction in the system process miui-theme-engine or a crowded cache of the application "Themes".

If the image "flys" and returns standard after rebooting, check access rights. Themes and Gallery applications should be allowed to change system settings. A third-party launcher can also cause problems, although it rarely affects the lock screen, most often widgets conflict.

• 🗑️ Cache Clearing: Go to Settings → Annexes → All applications → Topics → Memory and press "Clear cache".
• 🔄 Reset theme: Try applying the standard Classic theme in the Themes app and then reinstall your picture.
• 📐 File format: Make sure the image is not in an exotic format (e.g., file format, HEIC iPhone without conversion and weighs reasonably (up to) 10-15 MB).

⚠️ Note: If you use a third-party wallpaper installation app (not from the official Xiaomi store), the system may force the changes to be reset after a while for safety or energy saving purposes.

In some cases, especially after a firmware update, the zoom may get lost, the picture may become too dark or light, and this is treated by re-selecting the framing area in the preview menu before the final application.

Optimization and Impact on Productivity

Visuals don't have to be at the expense of functionality. A beautiful lock screen is good, but if it makes your smartphone slow down when you unlock it, it's meaningless, especially for devices with 4GB or less of RAM.

Using a wallpaper carousel with thousands of high-resolution photos can take up a significant amount of space in the system cache, and it is recommended to clean this cache through the storage menu, and it is also worth considering that complex live wallpaper can interfere with some quick unlock functions, since the system takes time to render the first frame.

For owners of devices with AMOLED-There's a simple advice for screens: use black-dominated images, which not only looks stylish, but actually saves battery life, because the black pixels on those arrays are just off. White and bright static interface elements on the lock, on the contrary, increase consumption.

💡

The optimal balance between beauty and performance is a high-quality static image (JPEG/PNG) with no complex parallax effects installed through the system menu.

In conclusion, setting up the lock screen on Xiaomi is a creative process that allows you to adapt your smartphone to your own needs: Experiment with methods, test the impact on autonomy and enjoy a personalized interface.
