How to record a call in Viber on Android

Modern communication has long moved to instant messengers, and Viber remains one of the leaders in this segment, especially in the CIS countries. However, the standard functionality of the application does not provide the user with the ability to record voice calls, which often creates inconvenience. Businessmen need to record agreements, and ordinary people need to save important conversations with relatives or support services.

The situation is aggravated by constant changes in security policy Android. Starting with version 9 and especially in Android 10, 11 and later, Google has significantly limited app access to the microphone during phone calls. This means that old methods that worked a couple of years ago may today produce a recording of silence or one-way audio.

However, there is a solution. In this article, we will look at the current methods of recording audio in 2026: from using built-in voice recorders to specialized software that can bypass system restrictions. You will learn which settings are critical for sound quality and how to avoid common mistakes.

Why there is no recording button in Viber and technical limitations

Many users mistakenly believe that the lack of a recording function is a flaw of the developers Viber. In fact, the company deliberately does not implement this option due to privacy concerns and compliance with privacy laws in different countries. Creating a built-in voice recorder would require the application to request dangerous permissions, which could make users suspicious.

The main problem lies deeper - in the architecture of the operating system Android. Google has implemented strict guidelines for using the microphone API. When a VoIP call (over the Internet) begins, the system blocks access to the audio stream for all third-party processes to prevent covert surveillance. This is why most simple voice recorders are silent during a conversation.

There is also a legal aspect. In some jurisdictions, recording a conversation without warning the other party is illegal. Messenger developers prefer to play it safe and not give users a tool that could lead to lawsuits against the platform.

⚠️ Attention: Before you start recording any conversation, make sure that it does not violate the laws of your country. In some cases, the verbal consent of the interlocutor to record the conversation is necessary.

Despite these barriers, enthusiasts and third-party software developers have found workarounds. They use either special accessibility services, or record sound not directly from the system, but through the speaker, using the second microphone of the device.

Using the built-in voice recorder and screen recorder

The most reliable, although not the highest quality, method is to use the tools already available in your smartphone. Many modern shells from Xiaomi, Samsung or Huawei have advanced built-in screen or voice recorders that can capture the internal sound of the system.

First, check for the presence of a screen recording function. It is usually located in the notification shade. If your screen recorder settings have a "Record Audio" option set to "Media Sound" or "Internal Sound," you're in luck. Start screen recording, call Viber, and the video file will contain the audio track of the conversation.

If your phone's built-in voice recorder can work in the background and does not stall when there is an incoming call, you can try starting it manually. However, in 90% of cases, when answering a call, system priority is given to the handset, and the voice recorder is paused automatically.

• 📱 Check the screen recorder settings for the option to capture internal audio.
• 🎙️ Test the standard voice recorder in "background recording" mode before an important call.
• ⚙️ Make sure that in the section Settings → Applications → Voice Recorder there is no restriction of background activity.

This method is good for its security: you do not install dubious software from unknown sources. But there is also a minus - the file will be large (video instead of audio), and you will have to convert it or just listen to it as a video recording.

Third-party applications for recording calls in Viber

The market for call recording applications is huge, but only a few of them actually work with VoIP traffic on the latest versions Android. The leader in this niche for a long time remains Call Recorder - ACR from NLL. This application uses complex algorithms to intercept the audio stream.

When launched for the first time, this application will require special permissions. Typically this includes access to the microphone, storage, and most importantly, Accessibility. Accessibility permission is needed so that the app understands exactly when the call to Viberstarted and ended, and automatically starts recording.

Another popular solution is Cube ACR. It is positioned as a universal recorder that supports not only regular calls, but also instant messengers: WhatsApp, Telegram and Viber. In the Cube ACR settings, you must manually activate the "App Connector" in the accessibility section.

Application	Support Android 13+	VoIP recording	Root required
Call Recorder - ACR	Partial	Yes (with settings)	No
Cube ACR	Yes	Yes	No
Boldbeast Recorder	Yes	Yes (complex setup)	No
TapeACall	Yes	Through a conference	No

It is worth noting that even the best applications can be unstable on different phone models. What records ideally on Samsung Galaxymay be silent on Google Pixel due to differences in the implementation of audio drivers.

Step-by-step guide for setting up Cube ACR

Let's look at the setup process using the example of one of the most functional solutions - Cube ACR. This algorithm of actions is relevant for most devices based on Android recent years of production.

First download the application from the official store Google Play and run it. The setup wizard will guide you through several steps. It is critical that you do not skip steps related to granting access rights. The system will ask for confirmation several times to enable the connector.

Next you need to go to the settings of the application itself. Find the "Audio sources" section. For recording calls in Viber, the source that is often best suited is VOIP or Mic. If the recording is quiet, try switching the source to Default or Voice Communication.

• 🔓 Grant all requested permissions, including running in the background.
• 🔌 Activate Cube ACR App Connector in your phone's accessibility settings.
• 🎚️ In the "Call recording" section, make sure that the switch opposite Viber is active.
• 💾 Select a saving format, for example MP4 or 3GP to save space.

After setting up, make a test call to a friend. Check the recording: if only you can be heard, it means that the application is recording from the microphone, but cannot capture the other person’s stream. In this case, turning on the speakerphone during a call will help.

⚠️ Attention: If the recording disappeared after updating the operating system, go to the application settings and disable and then enable the accessibility connector again. This often clears resolution errors.

The problem of the interlocutor's quiet voice and the hands-free method

The most common complaint from users after setting up a recording is “I can be heard perfectly, but the interlocutor is almost inaudible.” This happens because the application records the signal directly from the microphone, but the Android system mixer does not give it the stream of the remote interlocutor.

The simplest and most effective solution in such cases is to use speakerphone. When you turn on the speaker, the caller's audio comes out, is picked up by your phone's microphone, and is recorded as normal external audio. The quality will be slightly lower than with direct digital recording, but intelligibility is guaranteed.

Some advanced applications, such as Boldbeast Recorder, have complex audio gain settings (Gain Control). There you can try to increase the microphone sensitivity programmatically, but this often leads to noise and hissing during pauses.

If you are using a headset or Bluetooth headphones, the situation may change. In some cases, connecting headphones causes the system to redirect the audio stream so that it is easier for the recorder to intercept it. It's worth experimenting with different connection scenarios.

Why is it harder to record on Android 14?

In Android 14, Google has further limited background access to the microphone. Now the system can completely block recording if the application is not in the active window on the screen. The solution is to keep the recorder window open during the call.

Legal aspects and storage of recordings

The technical ability to record a conversation does not mean that it is always legal. In Russia, recording your own conversation for personal use is generally allowed. However, publishing such a recording in the public domain without the consent of the other party may entail liability for violation of privacy.

In a business environment, recording of conversations is often regulated by internal company rules and agreements with clients. If you are recording a conversation to prove something in court, make sure that the file storage chain has not been broken, otherwise the recording may not be accepted as evidence.

It is better to store recordings not only in the phone’s memory, but also in the cloud. Applications like Cube ACR allow you to configure automatic uploading of files to Google Drive or Dropbox. This will save your data if your smartphone is lost or damaged.

Pay attention to the storage period. Files take up space, and after a month the phone can be filled with gigabytes of unnecessary dialogue. Configure automatic deletion of records older than 30 days, leaving only important marked files.

Frequently asked questions (FAQ)

Why does the application record only my voice, but not the other person’s can you hear?

This is an Android security limitation. Try turning on the speakerphone during a call or change the audio source in the application settings to "Voice Communication" or "Mic". Also check if the antivirus is blocking the recorder's access to the system.

Are root access needed to record calls in Viber?

In most cases, on modern Android 11-14 root access is not needed if you use applications like Cube ACR or ACR with the accessibility connector enabled. Root may only be required on very specific firmware or for recording on older versions of Android.

Will the interlocutor know that I am recording the conversation?

Standard recording applications do not send any signals to the interlocutor and do not play sound notifications into the communication line. The interlocutor will not know about the recording unless you tell him or turn on a loud sound notification in the room.

Is it possible to record a video call in Viber?

Yes, for this it is best to use the built-in “Screen Recording” function with audio capture enabled. Specialized audio recorders do not save the video stream. Make sure that “Record system audio” is selected in the screen recorder settings.

Where are call recordings stored?

Usually the files are located in the folder /Internal Storage/CallRecorder or /Internal Storage/Cube ACR. You can find them through any file manager. You can also access the list of recordings inside the recorder application itself.
