Owners of the Poco X3 Pro smartphone often strive for maximum personalization of the device, beyond the standard capabilities of the MIUI system. One of the most popular functions is to install your own video as the background of an incoming call, which allows you to instantly recognize the caller or just please the eye with animation. The regular functionality of the shell from Xiaomi allows you to implement this task without installing third-party applications, but the process has its own nuances, which not everyone knows.
Unlike the installation of regular static images, video wallpaper requires some file preparation and format compliance to ensure that the system correctly recognizes the content. If you want to make your Poco X3 Pro unique, you do not need superuser rights or complex manipulation of system files.
It should be noted that the quality of the display depends on the resolution of the original video and its duration. Too long or heavy videos can cause delays when the call screen appears, so it is important to find a balance between visual attractiveness and device performance. In this article, we will discuss in detail the step-by-step algorithm of actions that is guaranteed to help you install video on the call.
Video preparation and technical requirements
The first and most important step is to find or create a suitable video. The MIUI system installed on the Poco X3 Pro has limitations on the length and format of the file, ignoring which will lead to the fact that the video will not install or be cropped. The optimal solution is to use short clips lasting from 5 to 15 seconds, as they quickly load into memory and do not create unnecessary load on the processor at the time of incoming call.
The file format should be compatible with the smartphone's hardware decoder. The most universal and recommended format is MP4 codeced H.264. If you download videos from social media, make sure it’s not protected. DRM-It has a security and an extension that can be read by a standard video player. The resolution of the video must match the screen of your device or be higher to avoid blurring when stretching.
For Poco. X3 Pro with him. IPS-It is important to consider the proportions of the sides of the screen and the refresh rate of 120 Hz. Vertical videos (9:16) look most organic, filling the entire screen without black stripes. Horizontal videos will either have to be framed or put up with empty margins on the sides, which significantly reduces the visual effect.
- 🎬 The optimal duration of the video is from 5 to 15 seconds for fast downloading.
- 📐 Recommended permission – not less 1080×2400 pixels to fill the screen completely.
- 📁 The file format should be.mp4.mkv for maximum compatibility.
- ⚡ The file size is desirable to keep within 10-20 MB to save RAM.
⚠️ Note: Do not use video files with broken audio stream or non-standard codec, as the system player MIUI They may not be able to process them, and the installation will end in error.
If you find the perfect video, but it's too long, you have to cut it off, you can do it right in the gallery of your smartphone or using third-party video editors, and the key is to save the final file in the device's memory in an accessible folder so that the system can find it.
💡
Use vertical videos shot specifically for smartphones, as horizontal YouTube videos will look less spectacular due to black bars on the sides of the screen.
Use of the built-in function "Live wallpaper"
In the MIUI shell, there is a native mechanism for installing video on a call that does not require third-party software, which is the most stable and does not consume battery power in the background, since the video is activated only at the time of the call. To start, you need to open the standard Gallery application and find the previously prepared video.
Once you open the video, click on the “More” button (usually the three dots at the bottom of the screen) and select “Install video wallpaper” from the menu that appears. The system automatically switches you to preview mode, where you can see how the video will look on the locked screen or when you call, and this is where the key display setting occurs.
It's important to choose the right application area. In the Poco X3 Pro installation menu, you'll have a few options: Lock screen, Desktop, or Incoming call. You'll need to select Inbound Call, so that the video is played when someone calls you. If you select Lock screen, the video will only work when the device is unlocked.
☑️ Pre-installing check
Some users may find that there is no option to “Install Video Wallpaper” because your version of MIUI does not have this component installed or disabled, in which case the system may offer to download the Live Wallpaper plugin from the GetApps app store.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Duration | 5-15 seconds | Minimum CPU load |
| Permission | 1080p (Full HD) | Clear picture without pixelation |
| Codec | H.264 / AVC | Hardware acceleration decoding |
| File size | 20 MB | Quick buffering when calling |
Once you select the Incoming Call, the system will apply the settings, so now when someone calls you, instead of a static picture, the video you choose will play back, which creates a live interface effect and makes using your smartphone more enjoyable.
Alternative method through the "Themes" app
If the standard way through the gallery for some reason doesn’t work, or you want a more sophisticated visual with watches and widgets over the video, you can use the official Themes app.This is Xiaomi’s built-in store that offers thousands of designs, including those that support video phone calls.
Run the Themes app on your Poco X3 Pro and go to the search section. Type in "Video ringtone" or "Video call." You'll see a lot of free and paid themes that change not only the wallpaper, but also the dialing interface. Choose your favorite theme and click "Download."
Once you download a theme, take your time to apply it fully. Often users only need a video to call, and a non-interface. In the theme preview menu, find the "Configure" or "Apply individual elements" button, and here you can select only "Video Call" or "Block screen" by ticking, leaving the remaining icons unchanged.
- 🎨 Thousands of ready-made animation options in the official store.
- ⏱️ Ability to adjust video display time.
- 🔊 Some topics include sound effects when ringing.
- 🔄 Automatic Content Update Through Themes App.
⚠️ Warning: When installing themes from third-party sources or unofficial stores, be careful: they may contain advertising or unstable code that affects the operation of the system.
Using the Themes app is especially convenient because it does not require self-search and convert video files. Everything is already optimized by developers for the screen resolution of Xiaomi and Poco. However, it is worth remembering that some topics can be heavy and occupy a significant place in the memory of the device.
Why can’t the video work after installing the theme?
Set up third-party applications for calls
In cases where the built-in MIUI tools do not meet the user’s requirements (for example, you need to install videos from Telegram or WhatsApp directly), you can resort to the help of specialized applications. One of the most popular and proven solutions is the Video Live Wallpaper app or analogues from Google Play.
The principle of these programs is to create a virtual layer on top of the standard call interface, and once you install the application, you'll need to give it the necessary permissions: access to media files, access over other windows, and permission to work in the background, without these rights, the video will not be able to start at the right time.
Once you have set up the app, select the video file you want from your phone’s memory. Many programs allow you to adjust video volume, playback cycles, and even the response to touch screens, which gives you more flexible customization options than standard Xiaomi tools.
However, this method has its drawbacks: Third-party applications can consume more battery life, as they are constantly hanging in memory, waiting for an incoming call. In addition, on some versions of Android and MIUI, the system can aggressively kill such processes to save energy, which may cause the video to fail.
If you choose this path, be sure to add the video calling app to the battery exception list. To do this, go to Settings → Battery and Performance → App Search, find your app, and select No Limits mode. This will prevent it from being forced to stop by the system.
Resolving common problems and errors
Despite the simplicity of the procedure, Poco X3 Pro users may face a number of technical problems: It often happens that the video is installed, but when an incoming call shows a static black screen or a standard screensaver, this indicates a problem with the compatibility of the codec or access rights.
One of the common reasons is the power saving mode on, where when the battery is below 20% or Ultra mode is on, the system turns off all animations and video effects to extend the device, in which case the video on the call will not work until you turn off the economy mode.
The problem can also be in the video audio format: If the video uses an audio codec that is not supported by the system bell (for example, some variations of AAC or FLAC inside MP4), the sound can disappear, and with it the video sequence. Converting the video to the basic stereo AAC format usually solves this problem.
- 🔋 Check if the “Energy Saving” mode is included».
- 📂 Make sure the video file is not moved or deleted after installation.
- 🔊 Check the sound settings: the video should not be silent unless the system requires it.
- 📱 Reboot your smartphone after installing new video wallpapers.
⚠️ Warning: If the phone starts to heat up during the call after installing the video, remove the wallpaper immediately.This may indicate poor codec optimization and overloading of the graphics accelerator.
In rare cases, cleaning the cache of the Themes and Wallpaper app helps. Go to Settings → Apps → All apps, find Topics, click Clear, and select Clear Cache. This will reset temporary files that may have been corrupted when you download a new video.
The effect of video calls on the autonomy of the device
Owners of the Poco X3 Pro, which features a powerful Snapdragon 860 processor and a 5160mAh battery, are often concerned about the impact of live wallpaper on the time of work, and it should be understood that playing video is a resource-intensive task that uses the CPU, GPU and screen simultaneously.
However, since video on a call is activated only when the call arrives and usually lasts no more than 30-40 seconds (maximum beep time before reset), the overall effect on the daily battery charge is minimal.
That's different if you use the "live wallpaper" on the lock screen, which is played constantly when you pick up the phone. 5-10% It's a daily routine, depending on the brightness and complexity of the animation, but for the video call feature, it's irrelevant.
💡
Video calls only consume energy for a few seconds during an incoming call, so their impact on the overall autonomy of the Poco X3 Pro is almost imperceptible.
However, using high-resolution (4K) video on a high refresh rate (120Hz) screen creates a short-term but high load. If you notice the phone starting to slow down when you call, try lowering the video quality or frame rate in the original file.
