How to install wallpaper on Xiaomi Redmi 7A: the complete guide

Personalizing the appearance of a smartphone is the first step that makes the new gadget truly yours. Xiaomi Redmi 7A, despite its budget cost, offers users ample opportunities to customize the MIUI interface. Replacing the standard image with a personal photo or high-quality art allows you not only to stand out, but also creates a more pleasant visual experience whenever you access the device.

The procedure for installing new background images on Android with a MIUI shell is intuitive, but beginners may encounter some nuances. There are several ways to accomplish this task: through standard system settings, directly from the gallery or using specialized applications. In this article, we will discuss all the available methods in detail so that you can choose the most convenient for yourself.

It is important to consider that the quality of the final result depends on the resolution of the original file. the screen of the Redmi 7A model has a diagonal of 5.45 inches and a resolution of 1440×720 pixels. Using images with lower quality will lead to the appearance of “grain” and artifacts, which will significantly spoil the experience of using the device.

Use of the built-in “Themes” application

The most popular and functional way to change the visual design is to use the Themes system app, which is pre-installed on all Xiaomi smartphones and provides access to a huge library of content, and you can find not only static pictures, but also complex animated wallpaper that will bring the desktop to life.

To get started, you need to start the app and go to the bottom tab, usually designated Wallpapers or Wallpapers. The system will offer several categories: nature, abstraction, art, etc. Once you select the image you like, click on it to preview. If you like the result, click Apply or Download, then the system will suggest you choose the application area: lock screen, desktop or both screens at the same time.

⚠️ Attention: An active internet connection is required to download content from the theme store.Make sure you use Wi-Fi if your plan has traffic restrictions, as some wallpapers can weigh several megabytes.

One of the key features of this method is the ability to install live wallpapers, which are short videos or animations that play in the background, but it is worth remembering that constantly rendering graphics can consume additional CPU resources and drain the battery faster, which is critical for budget models.

• 🎨 A huge selection of free and paid high quality images.
• 📱 Possibility of preview before installation.
• 🔄 Automatic update of the collection “Wallpaper of the day».
• ⚙️ Flexible application setting (only lock or only desktop).

If the standard library doesn’t meet your needs, you can search by keyword, and type in English or Russian to find specific images, such as “space,” “cars,” or “minimalism.”

Installation of image from the Gallery

Often, users want to see personal photos, photos of children, pets or landscapes taken during travel on their smartphone screens, in which case you do not need to search for pictures on the Internet, you just need to use the built-in file manager and the Gallery application, which is the most direct method and does not require connection to Xiaomi servers.

The algorithm is simple: Open the Gallery app and find the photo you want. Click on the image to open the control menu and select the Still button (usually three dots or a menu icon). In the action list you see, you need to find Set as wallpaper. The system will automatically open the framing editor.

This is where an important technical procedure is done, framing, and because the aspect ratio of a camera photo (often 4:3 or 16:9) may not match the aspect ratio of a Redmi 7A screen, you'll have to choose which part of the image to leave visible. Move the frame with your finger to choose the best one, and click Apply.

There's also an alternative way to go through the settings, go to Settings, select Wallpaper, and then click on the gallery icon at the top corner or the album selection button, and you can view all the images as a grid and select multiple comparisons.

An important aspect is the orientation of the image. If you set a horizontal photo as the wallpaper of the lock screen, when you turn the phone, the image can shift or crop in an unpredictable way. Vertical shots are best for this purpose.

Setting up wallpaper carousel

A unique feature of the MIUI shell is the Lock screen magazine, which allows you to automatically change the image on the lock screen every time you wake up your smartphone, creating the effect of constant updating and eliminating the need to manually search for new pictures.

To activate this mode, go to Settings → Wallpaper → Wallpaper Carousel. Here you can select thematic collections that will download automatically, and the system will decide which image to show next, based on your preferences and category.

But it has its own features to be aware of: first, the carousel requires a periodic internet connection to download new image packets; and second, it can conflict with third-party screen locking apps or widgets if they try to occupy the same area.

⚠️ Warning: Wallpaper carousels can consume additional traffic and battery power in the background. If you are critical to maximum autonomy, consider disabling autoloading new images in the feature settings.

Users can adjust the frequency and content sources, and you can also use the categories Travel, City, Nature, and others, and you can also turn off the picture description to make the screen look cleaner.

• 🖼️ Automatically change the picture at each screen turn on.
• 🌐 Download content from various thematic collections.
• ⏱️ Possibility of adjusting the intervals of update.
• 🚫 Option to completely disable the function at any time.

Use of third-party applications

If Xiaomi’s standard functionality isn’t enough, Google Play offers thousands of customized apps, led by the Wallpaper Engine, Backdrops, Zedge, and Walli, which often provide access to exclusive content from artists around the world.

One of the main advantages of third-party solutions is the presence of interactive wallpaper, which can respond to touch, device tilts or time of day, for example, the background can smoothly change color from dawn to dusk, synchronizing with real time in your area.

When installing these applications, pay attention to the permissions requested. They may need storage access (to save cache) and sometimes access to the network. Be careful with little-known applications that require unnecessary rights, such as access to contacts or a microphone, which can be a sign of unfair software.

Many enthusiasts use the Wallpaper Engine app in conjunction with the PC version to deliver complex animations to the phone, allowing Redmi 7A to stream the same dynamic scenes as the computer, creating a single ecosystem of visual style.

Technical nuances and screen resolution

When choosing an image for the Redmi 7A, it is important to understand the technical limitations of the display. The IPS LCD matrix in this model has a physical resolution of 1440 points vertically and 720 horizontally. Loading an image with a resolution of 4K (3840×2160) will not make the picture clearer, since the screen is physically unable to display more pixels than it has.

Moreover, the use of super-heavy files (for example, weighing more than 10 MB) can lead to slowdown of the interface.Redmi 7A RAM is limited (2 or 3 GB depending on the modification), and the system has to spend resources decoding and zooming giant images, which can cause micro-freezes when unlocked.

💡

The best solution is to search for or create images with a resolution multiple of the native screen resolution, such as 1440×720 or 2880×1440, which will reduce the load on the processor when zooming.

There is a concept of pixel density, or pixel density (PPI), which is about 296 PPIs in this model, and low-detail images will look blurry precisely because they stretch a small number of pixels per physical area of the screen.

Also worth considering is the color gamut. The screens of budget smartphones sometimes have less color reproduction than the flagship AMOLED-matrix. Therefore, images with high contrast and bright colors will look better on the Redmi 7A than faded or too dark photos.

⚠️ Note: It is not recommended to install video wallpaper with a high bitrate (more than that). 5-10 Mbps. Snapdragon processor 439, redmi-mounted 7A, may not be able to decode heavy video in real time, which will lead to heating of the case and rapid discharge of the battery.

Typical problem solving

Sometimes users are faced with a situation where after installing the wallpaper, they are displayed incorrectly: white bars are visible, the image is shifted or stretched, most often this is due to the wrong choice of framing area. MIUI has a separate preview tool that users ignore. Always check how the picture looks on both the desktop and the lock screen before the final confirmation.

Another common problem is that you can't install a picture because of a "Not enough memory" error. It doesn't mean you're overloaded. It creates a temporary cache file to process the image. If there's not enough RAM, the process is interrupted. Solution: close the background applications before installing.

If the wallpaper is spontaneously reset to the standard after the reboot, this may indicate damage to the system file cache theme, in this case, it will help to clean the data of the application Themes through the application management menu. Don't worry, your personal photos will not be affected, only the store cache will be reset.

• 🔍 Check the file format: supported JPG, PNG, GIF (static).
• 💾 Free up storage space if it is more than 90 times full%.
• 🔄 Reboot the device after installing "heavy" live wallpaper.
• 📵 Turn off energy savings if live wallpaper doesn't work.

In rare cases, the problem may lie in a third-party launcher. If you use an alternative shell (Nova Launcher, Lawnchair, etc.), wallpaper settings can be managed through them, rather than through the system settings of MIUI. Check the settings of the launcher itself.

💡

The quality of the source file and the resolution of the file with the physical parameters of the screen matrix are key factors for the perfect display of the image on Redmi 7A.
