Modern smartphones of the line Tecno, running on an operating system Android, offer users ample opportunities to personalize the interface. One of the most popular features is the replacement of a static image or standard animation for an incoming call with a full-fledged video. This allows you to make the communication process more lively and individual, distinguishing the device from hundreds of other gadgets. However, using standard system tools, this option is not always implemented straightforwardly, especially on different versions of the shell HiOS.
Device owners are often faced with the need to use third-party applications or specific settings of the built-in video editor to display the clip correctly. It is important to understand that the quality of playback directly depends on the resolution of the source file and the capabilities of your display smartphone. In this article we will analyze in detail all the available methods, starting from the manufacturer’s standard tools and ending with the installation of specialized software from Google Play. You will learn to bypass system limitations and create truly unique scenarios for incoming connections.
Preparing video content: formats and requirements
Before proceeding with the technical part of the setup, you need to make sure that your media file meets the technical requirements of the operating system. Android is quite flexible in terms of supported codecs, but to ensure smooth operation of the video call it is better to use standard formats. The most universal and recommended container is MP4 with codec H.264. It is this format that is guaranteed to be played on any device Tecno without delays and sound desynchronization.
Video resolution also plays a critical role. If the file is too heavy or has a resolution higher than the native smartphone screen, the system may automatically compress it, which will lead to loss of quality, or even refuse to install it for the call. The optimal choice would be a vertical video with a resolution of 1080x1920 pixels or 720x1280 pixels. Horizontal videos, when installed on the call background, will either be cut off at the edges or surrounded by black fields, which looks unaesthetic.
⚠️ Attention: The duration of the video should not exceed 15-30 seconds. Files that are too long can cause increased battery consumption in standby mode and take up unnecessary space in the system cache.
You can use the built-in gallery editor or third-party applications to edit source material. If you plan to change your call wallpaper frequently, it makes sense to create a separate folder in the device memory where you will put only prepared clips. This will simplify navigation when selecting a file through the system explorer.
Using built-in Tecno HiOS tools
The shell HiOSinstalled on smartphones Tecnooften contains its own tools for customization, which may not require the installation of additional software. First of all, you should check for the "Video Wallpaper" function or a similar option in the lock screen and call settings. The path to these settings may differ depending on the firmware version, but usually it is located in the personalization section.
To access basic settings, go to the menu Settings, then select Special. features or Personalization. There may be an option Smart panel or Magic screenwhere you can download short videos to display when you block or call. Some models Tecno allow you to assign a video directly from the gallery: open the desired file, click on the three dots in the corner of the screen and select "Set as", then "Video call" (if such an option is present in your software version).
If it is not possible to install video using standard methods, this means that the manufacturer has limited this function or it is implemented through a separate system application. In such cases, the system may prompt you to go to the application store to download the required module. Do not ignore system prompts, as they lead to official and safe solutions from the interface developer.
Why is there no "Video on call" button?
The function may be hidden depending on the regional firmware version. In some cases, it is necessary to update the system application "Phone" or "Contacts" through the Google Play Store to get new interface features.
Installation through the Video Call & Caller ID Name application
The most reliable and popular way to install video on an incoming call is to use specialized applications that replace the standard dialer. The leader in this niche is the app Video Call & Caller ID Name (or its analogs, such as Truecaller with a video function). These apps completely intercept the incoming call process, displaying your video on top of it.
After downloading and installing the application from Google Play, you will need to grant it a number of critical permissions. Without access to contacts, microphone and, most importantly, the right to “display on top of other applications,” the app will not be able to function correctly. Follow the instructions in the initial setup wizard to activate all the necessary services.
☑️ Setting up the application for video calls
Inside the app interface, you can select a specific video for all incoming ones or assign unique videos to individual contacts from the phone book. This creates the effect of a personalized approach: when mom calls, one video plays, and when a colleague calls, another video plays. The interface of such applications is usually intuitive and allows you to quickly change content.
- 📱 Flexibility: the ability to link a video to a specific phone number.
- 🎨 Effects and filters: built-in tools for improving picture quality before installation.
- 🔔 Notifications: Displays the caller's name on top of the video in a stylish format.
- 📹 Call recording: Some versions allow you to record a video call along with the displayed background.
⚠️ Attention: Replacement apps dialers may conflict with system blocking of spam calls. If you actively use Tecno's built-in antispam, check compatibility or set up exceptions.
Configuration through the Video Live Wallpaper app
Another time-tested method is the use of "live wallpaper" class applications adapted for the call screen. The application Video Live Wallpaper is one of the easiest and most functional solutions in this category. It does not replace the dialer interface, but is implemented into the system as a live wallpaper service, which is activated when a call arrives.
The installation process begins by selecting a video file in the main app window. After you specify the path to the file, the application will prompt you to configure display options. Here it is important to set the scaling correctly so that the image fills the entire screen without black bars. The function Crop (crop) allows you to cut off unnecessary parts of the video, focusing on the main object in the frame.
A distinctive feature of this method is the minimal consumption of resources. Unlike heavy dialer replacements, the live wallpaper service starts only at the right moment and does not constantly hang in the RAM in an active state. This is especially true for models Tecno with 4 GB of RAM or less.
To save battery power, set the application to play videos only when the screen is unlocked or the device is connected to Wi-Fi, if such an option is available in the Android power saving settings.
After setting the parameters, click the "Set wallpaper" button and select option "Lock screen and home screen" or only "Lock screen" if the app supports profile separation. Some versions of Android require additional permission for the application to access security settings.
Comparison of video call installation methods
The choice of video installation method depends on your priorities: picture quality, stability or functionality. Built-in tools are good because they are native, but they are often limited in capabilities. Third-party apps give you full control, but may consume more power. For a visual comparison of the main characteristics, consider the following table.
| Method | Setting complexity | Battery consumption | Format support |
|---|---|---|---|
| Built-in gallery | Low | Minimum | Limited (MP4) |
| Replacement application | Medium | High | Wide (MKV, AVI, MP4) |
| Live Wallpaper | Medium | Medium | Standard (MP4, WEBM) |
| Third-party HiOS theme | High | Depends on the theme | Depends on the theme |
As seen from tables, there is no universal solution. If autonomy is critical for you, it is better to use built-in tools or lightweight live wallpapers. If functionality and the ability to assign different videos to different subscribers are important, then replacement applications will be unrivaled. Remember that installing too heavy a video through any of the methods can lead to the interface slowing down during a call.
It is also worth considering that some methods require constant application access to the microphone and phone, which theoretically can reduce the level of data confidentiality. Always download apps only from the official store Google Play and check reviews from other users before installing.
Solving playback problems
During the setup process, users may encounter a number of technical difficulties. The most common problem is that video is installed, but a black screen or static picture is displayed when making a call. Most often this is due to the fact that the system does not have enough rights to draw graphics on top of the dialer interface. Check the permission settings in the section Applications -> Special. access -> Display on top of other applications.
Another common mistake is the lack of sound in the video during an incoming call. By default, many applications are set to play silently so as not to interrupt the ringtone. To fix this, go to the settings of the application you are using and find the item responsible for audio output. Make sure the media file volume slider is not at zero.
If the video plays jerkily, try reducing the bitrate or resolution of the source file. Smartphones Tecno entry and mid-price segments may not be able to decode 4K video in real time when a call comes in. Converting a file to 720p format often solves the problem of lags.
⚠️ Attention: Android shell interfaces and menu item names may differ depending on the version of the operating system and the model of your device. If you do not find an exact match, look for synonymous function names.
Optimization and impact on performance
Using video content as a call background is not only beautiful, but also resource-intensive. Processor and GPU smartphones are forced decode the video stream at a time when the system must also process the incoming signal and launch the communication interface. On older or budget models, this can lead to a short-term screen freeze.
To minimize the impact on performance, try not to use high FPS (frames per second) video. The optimal value is 30 FPS. Video with a frequency 60 FPS will create an unnecessary load, which the user most likely will not even notice on a small screen during a short call, but this will significantly consume the battery.
It is also worth monitoring the temperature of the device. If you actively use navigation, games and video calls at the same time, the phone may become warm. If you notice that after installing video calls, the device begins to heat up more than usual, it makes sense to return to static images or use lighter animated GIFs instead of full-fledged video.
The balance between visual beauty and performance is a key factor in the comfortable use of a smartphone. Do not sacrifice the speed of your device for the sake of spectacular but heavy video.
Regularly clear the cache of applications responsible for video calls. Over time, temporary files accumulate in them, which can slow down the launch of the video player at the critical moment of a call. This is a simple maintenance procedure that will extend the life of your Tecno and ensure stable operation of all functions.
Frequently asked questions (FAQ)
Is it possible to put video on a call without installing third-party applications?
Yes, this is possible if your model Tecno supports the "Video Wallpaper" or "Magic Screen" function in standard settings. However, the functionality will be limited compared to specialized applications.
Why is the video on a call played without sound?
Most likely, the “Video sound” or “Play audio” option is disabled in the application settings for video calls. Also check if the phone is in silent mode, although the media track should sound separately.
Does video on a call affect the rate of battery drain?
Yes, it does. The screen and processor work in enhanced mode during an incoming call. However, since the call duration is usually short, you will not notice a significant difference in battery life if you do not use 4K video.
Are 4K videos supported on all Tecno models?
Not on all. Budget models may not be able to decode 4K in real time for an incoming call, which will lead to slowdowns. It is recommended to use a resolution of 1080p or 720p for maximum compatibility.
How to remove a video and return the standard image?
To do this, go to the settings of the application that installed the video (or to the live wallpaper settings), and select the option "Reset" or "Use default system image."
