Modern Xiaomi smartphones have long ceased to be just devices for calls, becoming powerful multimedia centers that allow you to stay in touch with loved ones anywhere in the world. Video communication has become the standard of communication, and owners of Mi, Redmi and POCO often face the need to quickly and efficiently customize this functionality. Despite the thoughtfulness of the shell MIUI or HyperOS, sometimes there are nuances that require user intervention.
In this article, we will discuss how to properly configure a video call on Xiaomi to avoid problems with image quality or lack of sound. You will learn about hidden system settings, the features of various applications and methods of optimizing the network for seamless broadcasting. Proper device configuration will allow you to enjoy a clear picture even with imperfect coverage of the mobile network.
Before we get to specifics, it's important to understand that video quality is not just about the phone's settings, but also about the state of the software. Make sure your version of the operating system is up to date and all the necessary permissions for applications are issued. It's the foundation on which video services are built to work smoothly.
Checking the basic settings of the camera and microphone
The first step in how to set up a video call on Xiaomi is to check the basic permissions. The Android system on which MIUI is based strictly controls access to sensitive modules such as the camera and microphone. If the application does not have permission to use them, video communication will simply not start or will work with errors.
Go to Settings → Apps → All apps. Find the messenger or service you plan to use (such as WhatsApp, Telegram, Google Duo or the built-in Theme) in the list. Click on it and select App Resolution.
☑️ Permit verification
Note that new versions of the HyperOS shell have added an additional layer of protection, and in the upper right corner of the screen, an indicator (green dot or camera icon) may appear to signal the operation of the video module. If you see this indicator but there is no image, access may be blocked at the security level.
⚠️ Warning: Do not give permission to use the camera and microphone to unknown applications from unreliable sources.This can lead to leakage of personal data and covert surveillance of you.
It's also worth checking if the camera is blocked in Do Not Disturb mode or special profiles. Sometimes users forget that they have activated a privacy mode that blocks sensors, and resetting a particular app to factory settings often solves the problem if standard switches don't respond.
Set up video calls through the built-in Phone application
Many users are unaware that Xiaomi smartphones have a built-in feature of video calls via the cellular network or Internet Protocol operator (ViLTE), which does not require the installation of third-party programs. To use it, you need to properly configure the Phone application (usually Google Phone or MIUI Dialer).
Open the Phone app and click on the three dots in the upper right corner, then select Settings. Find the Video Call or Video Settings section. This may require activation of the service from your mobile carrier, as the feature itself often depends on your support for the VoLTE or ViLTE standard.
If there is no video settings, it may mean that your SIM-The card does not support this function, or the operator does not provide video calling service in your region, in which case the setting is reduced to checking the status of the card. SIM-maps in the menu Settings → SIM-Maps and mobile networks. pastikan that the "Use VoLTE" switch is active.
Why is video calling through the operator paid?
To make a call, a video camera icon may appear in the dialing interface next to the call button, and you click on it and initiate a video session.
Optimization of messengers: WhatsApp, Telegram, Viber
The most popular way to communicate remains messengers. To set up a video call on Xiaomi to work on WhatsApp, Telegram or Viber without delay, requires deep adjustment of power consumption. MIUI system aggressively saves battery power, often “killing” the background processes of messengers, which leads to missed calls or a long connection.
Go to Settings → Battery and Performance. Find your communication app on the list and set the No Limits mode, which will prevent the system from forcibly shutting down the messenger process, and in the application settings (within the Data and Storage section), you can select the video quality: Auto, Good, or Best.
- ✈️ Telegram: In the section "Data and memory» → «Calls can be selected for a specific proxy or server to call, which sometimes helps improve the connection (P2P).
Special attention should be paid to setting notifications. If the phone does not ring when the video is coming in, check the notification settings in the Notifications → Control Center section. Make sure that the messenger is allowed to display lock screen and pop-up notifications.
💡
Use the Game Accelerate or Game Turbo feature not only for games, but adding a messenger (like Skype or Zoom) can prioritize its traffic and CPU resources, improving video stability.
Use Google Meet and other services for business
For business meetings and training, platforms like Google Meet, Zoom, or Microsoft Teams are often used. Set up a video call on Xiaomi for these services requires a stable Internet connection and the right screen and audio permissions, and these applications are more demanding on processor resources.
When you first start Google Meet on Xiaomi, be sure to allow access to contacts to see the names of the interlocutors, and access to the microphone. In the settings of the application itself (cogwheel before entering the conference), you can select the default camera if multiple devices are connected, and configure noise suppression.
| Annex | Network requirements | Feature of setting up on Xiaomi |
|---|---|---|
| Google Meet | Stable 4G/Wi-Fi | Requires Google Play services, auto-setting quality |
| Zoom | High speed. | You need to manually allow “Above Other Windows” to display the screen. |
| Skype | Average speed | Often requires a separate microphone setting in the system. |
| Discord | Low ping | It is important to turn off energy saving for background work |
If you plan to display the screen during a video call, the system will request special permission to record the screen. On Xiaomi, this window may overlap with other elements. Be prepared to quickly click "Start recording" or "Allow" because the waiting time is limited.
⚠️ Note: When you show your screen in a video call through third-party apps, Xiaomi may stop transmitting sound due to a conflict of audio streams. In such cases, use a headset or switch the sound to the phone speaker.
Solving problems with sound and image quality
A common problem for Xiaomi users is the low image quality or lack of sound during a video call. If the picture "crumbles" or freezes, first check the Internet speed. HD-The quality requires a stable speed of at least 2-3 Mbps to incoming and outgoing channel.
Try switching between Wi-Fi and mobile Internet. Sometimes the router is overloaded and the 4G/LTE mobile network provides more stable ping, and it's also worth checking if Traffic Saving mode is included in network settings, which can artificially understate the quality of video streaming.
If you have a problem with sound (you can't hear or you can't hear the person), check if you select a Bluetooth headset that is far away or discharged as your output device. In the sound settings (Settings → Sound and vibration), make sure that the media and call volume levels are twisted high enough.
Contamination of the main or front camera is a common but common cause of cloudy images. Wipe your lenses with a soft cloth. Also check if the protective film is glued to the camera area, which often happens after repairing or buying a new case.
💡
90% of problems with video quality on Xiaomi are solved by switching the application’s energy saving mode to “No Limits” and checking the stability of the Internet connection.
Additional features and hidden functions
The MIUI shell and the new HyperOS offer a number of unique features to improve video communication. For example, Portrait mode in video calls can blur the background, hiding clutter in the room. This feature is available in many native applications and some messengers through system effects.
Owners of smartphones with AMOLED-The screens can evaluate the "Always on screen" mode during a conversation to see the time or notifications without interrupting the video session. 5G Setting up a preferred network type can significantly reduce video stream latency.
For users who often hold conferences, the Floating Window feature is useful, so you can roll up a video call into a small window and continue to use other applications, such as taking notes or searching for information in the browser without interrupting visual contact.
Don’t forget to use external cameras via USB-OTG. Xiaomi supports webcam connectivity, which can be critical for a smartphone or tablet-based stationary video call center.
