Mobile communications have long ceased to be just a means of voice transmission, turning into a powerful tool for organizing teamwork and communicating with large groups of people. Users Androidsmartphones are often faced with the need to quickly gather colleagues or friends in one audio channel without using complex third-party applications. The built-in functionality of modern instant messengers allows you to do this in literally a couple of clicks, providing high quality sound even with unstable Internet.
The process of organizing conference calls in the popular instant messenger has undergone significant changes over the past year, expanding its capabilities. Now you can not only make calls, but also screen share, use noise reduction and manage participant rights right from your phone. It is important to understand that group call has its own technical limitations and features of working on different versions of the operating system.
In this article we will look in detail at how to initiate a conference, configure quality parameters and solve typical problems that arise among owners of devices based on Android. You will learn about the hidden capabilities of the interface and how to optimize traffic consumption during long calls.
Technical requirements and device preparation
Before you start creating a conference, you need to make sure that your device meets the minimum system requirements. For stable operation of video communication and audio channels with a large number of participants, the current version of the application is required, which can be found in the official store Google Play. Outdated software versions may not support new audio compression codecs, which will lead to desynchronization of audio and video streams.
The quality of the connection directly depends on the bandwidth of your communication channel. For comfortable communication in a group of 5-10 people, we recommend an Internet speed of at least 2 Mbit/s for downloading and uploading. If you plan to broadcast the screen or enable video calling for all participants, the requirements increase to 5-10 Mbps.
⚠️ Attention: When using mobile networks (3G/4G/5G), make sure that your tariff plan includes a sufficient amount of traffic. Group video calls can consume up to 500 MB of data per hour depending on the number of active cameras.
It is also worth checking the permission settings on the system Android. Go to Settings → Applications → Telegram → Permissions and make sure that access to the microphone and camera is allowed. Sometimes, after a system update, these settings are reset, blocking the ability to start a conversation.
☑️ Check readiness for a call
Particular attention should be paid to background processes. If your phone is running heavy games or downloading large files, this may cause delays (ping) in voice chat. Close unnecessary tabs and applications before starting an important conference.
Step-by-step guide: creating a group and starting a call
There are two main ways to start a conference: through an existing group or by creating a new chat specifically for the call. The first option is most convenient for regular meetings with the same circle of people. Open the desired chat in the dialog list and find the phone icon at the top of the screen.
Click on the video call or audio call icon. In the menu that appears, select the option "Start voice chat" or "Start video chat". The system will prompt you to select participants from your contact list or invite them via a link. This is a key difference from a regular call: you create a room that people can enter and leave as they please.
- 📞 Click on the handset or camera icon in the chat header.
- 👥 Select the option to create a voice or video chat.
- 🔗 Copy the invitation link and send it to the participants.
- 🎛️ Set up access rights (who can speak, who can see the video).
If you do not have a group created yet, go to Chats tab and click on the pencil or message icon in the lower right corner. Select item "Create a group". Add at least one participant to enable calling features. Without participants, the call button may be inactive in some versions of the interface.
Use the "Invite via link" function to quickly connect a large number of people. There is no need to add each user to your contacts manually - just send the URL to another messenger or social network.
After the conference starts, you will see an interface with the participants’ avatars. To switch between audio and video mode, use the corresponding buttons on the bottom control panel. Remember that turning on video for all participants at the same time can significantly load the processor of your smartphone.
Participant management and access rights
The call organizer has advanced management rights, which is especially important when conducting webinars or meetings. You can mute participants' microphones that create background noise, or turn off cameras to save bandwidth. To do this, click on the avatar of a specific user in the list of participants.
In the rights management menu, you can set the “Only organizers can speak” mode. This turns the call into a lecture or presentation, where listeners can only watch and chat, but not interrupt the speaker. This function is not available in regular phone calls and is a unique feature group chats.
| Type of right | Description of opportunity | To whom it is recommended |
|---|---|---|
| Sending messages | Permission to write in the text chat of the call | All participants |
| Adding participants | Ability to invite new people via link | Only administrators |
| Pinning messages | Fixing important information at the top of the chat | Organizers |
| Broadcast management | The right to turn on/off video and sound for others | Only the creator |
To remove a noisy participant from the air, use the "Exclude" function. The person will be immediately disconnected from the conference and will not be able to re-enter without a new invitation. This is an effective method of combating spammers or trolls in open broadcasts.
How to assign a co-host?
Go to the participant’s profile inside the call, click on the three dots and select “Assign as voice chat administrator.” This will give him the rights to manage other participants.
The control interface may differ slightly on different smartphone models Samsung, Xiaomi or Pixel due to the characteristics of the manufacturer's shells. However, the operating logic remains the same for the entire platform Android.
Screen sharing and multimedia
One of the most popular features in modern business communication is the ability to share the contents of your screen with other participants. This is indispensable for presentations, training, or demonstrating software bugs. On Android this function works stably, but requires system confirmation.
To start broadcasting, click on the screen icon in the call control panel. The system will issue a warning that the entire contents of your display will be visible to others. Click "Get Started" or "Start now". Now any action you perform on your phone, from opening a browser to viewing photos, will be broadcast live.
⚠️ Attention: Before starting the demonstration, close personal correspondence, banking applications and notifications with confidential information. Audio from the device can also be broadcast, so be careful when playing media files.
The quality of the broadcast depends on the screen resolution of your smartphone and Internet speed. On high-resolution devices (2K, 4K), the image can be automatically compressed to save resources. You can switch between the front and rear cameras during the demonstration if you need to show some physical object.
Screen sharing works even in the background: you can minimize the messenger application and the broadcast will continue while you show other apps.
To stop the display, just press the button "Stop" in the floating window or return to the call interface. Participants will see a notification that the broadcast has ended and return to the grid view with avatars.
Adjusting sound quality and noise reduction
The problem of background noise is relevant for many users who call from public places, an office or a home where household appliances are running. Sound processing algorithms in the latest versions of the application have learned to effectively filter extraneous sounds, such as barking dogs, the clatter of a keyboard, or traffic noise.
In the call settings (three dots or gear icon) you can find the “Noise Suppression” item. Three modes are available: "Auto", "Always on" and "Never on". The mode "Always on" is the most aggressive and may slightly distort the voice, but guarantees clear air even with an open window next to the road.
- 🔇 "Auto" - the algorithm decides when it is necessary to suppress the noise (recommended).
- 🎙️ "Always" - maximum filtering, suitable for noisy streets.
- 🎵 "Never" - mode for musicians or podcasters, transmitting the entire spectrum of sounds.
If you are using a headset Bluetooth, make sure it is connected before starting call. Switching between the phone speaker and headphones during a call sometimes causes a momentary loss of sound. To force the selection of an audio output device, click on the speaker icon in the call interface.
It is worth noting that on older smartphone models with single-core or weak dual-core processors, enabling powerful noise reduction can cause the case to heat up and quickly drain the battery. In such cases, it is better to use the "Auto" mode or call from a quiet room.
Solving typical problems and errors
Despite the stability of the service, users may encounter technical failures. The most common problem is the lack of sound for one of the participants or for all of them at once. First of all, check if the microphone button is pressed in the application interface. Often, users accidentally tap on the screen and mute themselves.
If there is sound, but the video freezes or shows a black screen, try switching the network. Switch from Wi-Fi to mobile data or vice versa. Sometimes providers block certain ports used for P2P connections in instant messengers. Enabling a VPN can help bypass such restrictions, although it will increase signal delay.
⚠️ Attention: If the application constantly crashes when trying to make a video call, try clearing the cache in the Android settings (
Settings → Applications → Telegram → Memory → Clear cache). Do not confuse this with clearing data, which will delete all chats!
Another common situation is the inability to invite a participant. Make sure that the person is not blocked from being added to groups in their privacy settings. In this case, he can only enter the call using a direct link that you send him personally.
What should I do if the interlocutor can’t hear me, but I can hear him?
Check the microphone access rights in the system. If everything is fine there, restart your phone. Often this solves the problem of a frozen audio driver.
In the event of global server failures, when no one’s calls are connected, it is worth checking the official news channels of the service. Typically, technical work is carried out at night, Moscow time, and lasts no more than 15-20 minutes.
Frequently asked questions (FAQ)
How many people can be in a group call at the same time?
Currently, the participant limit for voice and video chats in groups and channels is up to 1000 people. However, only a limited number of users can talk and turn on video at the same time (usually up to 30 with video), the rest act as listeners.
Is it possible to record a group call on Android?
There is no built-in call recording function in the application itself. However, you can use the screen recording function available in most modern shells Android (Xiaomi, Samsung, OnePlus). Please note that when recording a screen, the audio of your interlocutors may be recorded quietly or not at all due to system security restrictions.
Is the Internet wasted if I just listen but don't speak?
Yes, traffic is constantly consumed while you are in the room, even if your microphone is turned off. The app continues to receive audio streams from other participants. You can save battery and traffic by minimizing the application, but then you will stop hearing the conversation.
Will my phone number be visible to other participants?
No, phone numbers are hidden in group calls and voice chats. Members only see your name and avatar that you set in your profile. This provides a high level of anonymity compared to regular telephone conferences.
Is it possible to enter a call from a computer and phone at the same time?
Yes, you can be connected to the same voice chat from multiple devices under one account. The sound will be duplicated, so it is recommended to turn off the microphone and speakers on one of the devices to avoid echo.
