How to install live wallpaper on a Xiaomi call

Personalizing a smartphone’s interface is one of the most enjoyable ways to make a device truly your own. Owners of Xiaomi, Redmi and POCO often look for ways to differentiate their gadget from others using not only standard themes but also dynamic elements. Live wallpapers can turn a boring lock screen into an interactive piece of digital art that responds to touch or system events.

However, standard MIUI or HyperOS functionality does not always allow direct assigning of a video file to the incoming call screen without using third-party tools. Users often confuse lock screen wallpaper and call background, although technically they are different system processes. To implement this plan, you will need not only the desire, but also an understanding of which files and applications can interact with the Android call system.

In this article, we will take a look at all the available methods, from built-in theme theme apps to custom widgets that replace the standard call interface. You will learn how to properly prepare video material so that it does not drain the battery in a matter of hours, and what file formats your smartphone model supports. The key is the use of call launcher applications, since the native Xiaomi gallery does not know how to put video on an incoming call directly.

Differences between live wallpaper and video call

Before you start installing, you need to clearly understand the architectural limitations of the Android operating system on which Xiaomi smartphones are based. Standard "live wallpapers" (Live Wallpapers) are essentially animated images that work on the desktop or lock screen, they are rendered by the system as a background layer and do not have direct access to the interface of the phone book or the screen of the incoming call.

The incoming call screen is a separate system overlay that has the highest display priority. Normal wallpaper cannot penetrate that layer. That's why trying to install video through a standard gallery as desktop wallpaper will not produce the desired result when a call arrives. To display video at the time of the call, either support from the theme or the use of a special caller application is required.

There are three main approaches to implementing this function, each of which has its own technical features:

• 🎨 Design topics: Using the built-in "Themes" application, where the video background is already integrated into the call interface by the theme developer.
• 📞 Third-party calls: Install an alternative call app that completely replaces the standard interface and supports video backgrounds.
• ⚙️ Widget overlays: Apps that create a transparent layer with playable video over the call screen (requires special permissions).

⚠️ Note: Using third-party apps to replace the call screen may lead to conflicts with the system phone book or delays in displaying the caller number.Always check reviews before installing.

The choice of method depends on your version of MIUI and region, as in some firmware (e.g. Global) the functionality of the themes may be limited compared to the Chinese versions.

Use of the "Themes" application to install a video background

The most naive and safest way to change the look of a call is to use the official Xiaomi theme store. Many designers create themes that already have a video background for the call screen. It doesn't require the installation of suspicious software and works at the system level.

To start, open the standard Themes app on your device. In the search box, type in queries like "Video Call", "Live Call" or "Animated Caller." In the search results, pay attention to the preview: if you see movement in the thumbnail, then the theme contains video elements. After selecting the appropriate theme, click "Download" and then "Apply".

It's important to understand that using a theme changes not only the wallpaper of the call, but also the icons, fonts and system sounds. If you only need a video background, you can go to the personalization settings after using the theme and return the standard icons, leaving only the style of the call.

It is worth noting that newer versions of HyperOS have made the theme algorithm more stringent, and some older video themes may not be displayed correctly or removed from the directory. If standard search does not yield results, try changing the region in the Topics app settings to India or Indonesia, where the directory is often richer.

Third-party applications for video calls

If the built-in MIUI doesn't suit you, specialized applications from the Google Play Store come to the rescue, acting as an alternative "caller" or creating its own interface on top of it, the most popular solutions are Video Live Wallpaper, Call Screen Theme & Background and their counterparts.

The way these applications work is that they ask permission to display over other windows and access the phone book. When an incoming call comes in, the system passes control to the application, which shows your uploaded video. The installation process is usually as follows:

• 📥 Download the app (e.g., Video Caller Theme & Background").
• 🎬 Download your video or select from the built-in application library.
• 🔐 Provide all the permissions requested (contacts, phone, display over windows).
• ✅ Install the application as the main one for making calls (if required).

But there’s a big nuance: In modern versions of Android (11, 12, 13 and above), security policies have been tightened significantly, the system can block third-party calls or require constant confirmations, and such applications can consume a significant amount of RAM.

It is recommended to test each application for several days, tracking missed calls, and if you notice that the phone stopped ringing or vibrating on an incoming call after installing such a program, immediately delete it and return the standard call.

Video File Preparation: Formats and Optimization

The quality of the display of live wallpaper depends directly on the source material. 4K-Video with a bit rate of 50 Mbps will cause the phone to heat up and the battery to drain in front of the eyes.

The ideal video file to be installed on a call should be short (5-15 seconds) and vertically oriented (9:16) to fill the entire screen of the smartphone without black fields. Horizontal video will have to be stretched or cropped, which will worsen the picture quality. The optimal resolution for most Xiaomi screens is 1080×2340 pixels.

To convert videos, use free tools on your PC or mobile editors. You need to achieve the following parameters:

• 🎞️ Codec: H.264 (AVC) or H.265 (HEVC) for better compatibility.
• 📉 Bitrate: No more than 2-3 Mbit / s (saving processor resources).
• 🔁 Cyclicality: Videos must have an imperceptible beginning and end joint (loop) so that the animation doesn’t twitch.

It is also important to consider the file format. Although Android supports many containers,.mp4 and.mkv are the most stable..gif files are not recommended: they often have a limited color palette (256 colors) and a large weight at low quality.

⚠️ Attention: Do not use video with a soundtrack for live wallpaper calls. The sound of the video will conflict with the melody of the caller or the voice of the caller, creating a porridge of sounds.

If you use a third-party app, check its settings: some of them have a built-in compressor that will automatically reduce the quality of the video when you download it, and it is better to do this in advance under controlled conditions, saving the source.

Compatibility table of MIUI methods and versions

Not all methods work equally well on different firmware versions, and here is a summary table that will help you choose the right way depending on your model and version of the software.

As you can see from the table, with the release of HyperOS, Xiaomi has increased the protection of system processes, which made the work of third-party calls less predictable, owners of new smartphones should rely primarily on official themes or the feature “Super Wallpaper” if it is available in your region.

If you’re using a global firmware version, the functionality may be different from the Chinese version. There are more live content partners available in China, while global versions are often limited to a basic set of static and simple animated images.

Setting up performance and energy consumption

Installing video on a call screen is a resource-intensive operation: the processor must decode the video stream in real time, and the screen must maintain a high frame refresh rate. On budget models of Redmi or POCO, this can cause noticeable micro-latency (freeze) in the interface.

To minimize the impact of live wallpaper on autonomy, follow these guidelines: First, avoid installing video wallpapers if you have Power Savings mode on, in which the system forcibly restricts background activity and processor frequency, which will cause the video to twitch or not start at all.

Second, check your screen settings. If your smartphone supports adaptive refresh rates (e.g. 60/90/120Hz), make sure the call app doesn't block mode switching. Sometimes fixing a high frame rate on the video call background quickly drops the battery.

💡

Use black video wallpaper for AMOLED-On these displays, the black pixels are simply turned off, which saves energy and prevents the matrix from burning out.

It is also worth regularly cleaning the cache of the application that is responsible for playing video. Over time, temporary files accumulate there, which can slow down. You can do this through Settings → Apps → All apps → [Your call app] → Clear the cache.

Problem Solving and Troubleshooting

Even following the instructions, users may encounter a number of typical problems, such as a video set, but when the call is displayed a black screen or a static picture, most often due to the system "killing" the application process to save energy.

To prevent this, you need to set up autostart and work in the background. Go to Settings → Battery and Performance → Application Management. Find your video calling app and let it "Start" and work in the background. Without this, MIUI will ruthlessly close the process a few minutes after the screen is turned on.

Another common problem is desynchronizing audio and video or not vibrating, which is often treated by resetting the call app itself or reinstalling the theme, and if nothing works, try using a video with a different codec or lower resolution.

If you are faced with the situation that after installing the video wallpaper, the proximity sensor stopped working (the screen does not go out when you hold the phone to your ear while you are talking), immediately remove the third-party application. It could have intercepted the sensor control, and this can only be corrected by returning to a standard caller.
