Are you faced with the fact that your interlocutors cannot hear you during calls to VKontakte, or the application refuses to record voice messages? Often the problem lies not in a malfunction of the smartphone itself, but in a banal lack of access rights. Modern versions Android strictly control user privacy, so upon first launch or after updating the system, permissions may be reset.
Lack of access to audio input makes it impossible to use key functions of the social network, such as video calls, creating stories with voice accompaniment, or sending short audio circles. In this material, we will analyze in detail how to restore the functionality of the microphone through the settings of the application itself and the system parameters of your device. It will only take a couple of minutes, but will save you hours of nerves.
The instructions are relevant for most popular smartphone models, including Samsung, Xiaomi, Huawei and other devices based on a clean or custom shell Android. We will consider both standard solutions and specific cases related to energy saving and third-party antiviruses that can block the operation of sensors.
Checking permissions inside the VKontakte application
The simplest and most often ignored step is checking the internal settings of the application itself. In the latest updates VK added the ability to manage some privacy settings directly from the app interface, although the main control still remains with the system. If you previously accidentally clicked “Deny” when asking for rights, the application will no longer ask for permission again without your intervention.
Go to your profile and open the settings section. It is usually hidden behind the gear icon in the top corner of the screen or in the side menu. Find the item responsible for privacy or call settings. The status of the current microphone access can be displayed here. If you see a warning that access is blocked, the system will offer to redirect you to the appropriate phone menu.
However, in 90% of cases, rights management is placed exclusively in the system settings of the operating system. The application only requests them when the function is launched for the first time. If the request was rejected, the microphone icon in the chat will be crossed out or inactive. You should not look for the “unmute microphone” button inside the dialog - it simply isn’t there, since this is a matter of system security.
⚠️ Attention: After updating the operating system to a new version Android (for example, from 12 to 13 or 14), all previously granted permissions may be reset for security purposes. You will have to go through the granting process again.
If the microphone button in the chat is gray and cannot be pressed, do not try to restart the phone right away. First, check if the “Silent” or “Do Not Disturb” mode is turned on on your phone, since in some shells this also blocks audio recording.
Setting access rights through the Android system menu
The main way to solve the problem lies in the depths of the system settings of your smartphone. The interface may differ slightly depending on the manufacturer, but the logic of action remains the same for the entire ecosystem Android. You need to find the application manager, where all the access rights data for the installed software is stored.
The action algorithm is as follows:
- 📱 Open
Settingsyour smartphone through the gear in the notification shade or main menu. - 📂 Go to the section
Applications(sometimes called “All applications” or “Manage applications”). - 🔍 In the list, find VK or VKontakte and tap on it to open the application card.
- 🛡️ Select an item
Permissions(Permissions). - 🎤 Find in the list Microphone and make sure the switch is active or the Allow mode is selected.
In some versions of the shell, for example in MIUI from Xiaomi or One UI from Samsung, the path may be slightly different. Sometimes the "Permissions" option is hidden inside the "Advanced" or "Security and Privacy" submenu. If you cannot find the item you need, use the search bar at the very top of the settings and type in the word “Microphone” or “Permissions.”
If the switch is already in the “On” position, try turning it off, wait a couple of seconds and turn it on again. This action triggers the service to re-register with the system and often helps to “wake up” a frozen audio input driver. After that, completely close the application VK (unload from memory) and restart it to check.
☑️ Microphone access diagnostics
Settings features on different versions of Android
Starting with version Android 12, Google has introduced the “Approximate Location” feature and tightened controls over the microphone and camera. There is a green dot indicator in the top right corner of the screen that lights up whenever an app is using the microphone. If you see this dot, but there is no sound, then there is access, but the problem is different.
In Android 13 and newer, it became possible to grant permissions only while using the application (“Allow only while using”). This is the safest and recommended mode. If you set the “Always Allow” option, this does not affect the operation of calls, but it consumes more resources in the background. The main thing is not to select the “Deny” or “Ask every time” option if you plan active calls.
On older versions of the system (below Android 10), rights management could be more vague. Sometimes microphone access was combined with voice recorder or screen recording access. In such cases, you need to look for the “Record audio” item in the permissions. Also, on older devices, it is worth checking whether the compatibility mode for older applications is enabled, which may block modern audio transmission protocols.
| Android version | Rights management type | Indication features |
|---|---|---|
| Android 10 and below | Static (on/off) | Absent |
| Android 11 - 12 | One-time or when used | Green dot in the status bar |
| Android 13+ | Granular control | Indicator + Quick access panel |
| Android 14+ | Advanced security | Block background recording by default |
What to do if the Microphone item is not in the list of permissions?
This is a rare situation that may indicate corruption of the application manifest file. Try clearing the application cache or reinstalling it. As a last resort, check for system updates for your smartphone.
The impact of power saving mode on microphone performance
Aggressive energy saving algorithms, especially on Chinese smartphones (Xiaomi, Honor, Oppo, Vivo), can “kill” background application processes, including access to audio. If a hard limit is set in the battery settings for VK the system may block the microphone from initializing immediately after you minimize the application or the screen goes dark.
To eliminate this factor, go to the battery settings. Find the section Battery consumption by applications or Activity control. Select VKfrom the list. You need to change the operating mode from “Energy Saving” or “Hard Restriction” to "No restrictions” or “Do Not Restrict”. This will allow the application to freely use microphone resources even in the background, which is critical for the stability of calls.
It is also worth checking for the presence of a special "Super Energy Saving" mode. In this mode, the phone disables almost all functions, leaving only calls and messages, and access to the microphone for third-party applications will be completely blocked at the system level. Exiting this mode will return full functionality.
⚠️ Warning: Disabling battery limits may drain your battery slightly faster if you leave an app running in the background for long periods of time. It is recommended to return restrictions if you do not use calls all the time.
The stability of the microphone in VK directly depends on whether the application is allowed to work in the background without restrictions from the energy saving system.
Third-party antiviruses and access blockers
Users who have installed additional tools protections, such as Kaspersky, Dr.Web, Avast or CCleanermay encounter access blocking at the level of third-party software. These apps have their own Privacy Guard modules, which intercept application requests to sensors before the system processes them.
Go to the interface of your antivirus. Find the section associated with access rights, confidentiality or App Lock. Check the list of blocked actions. If you see that VK there is a ban on using a microphone, uncheck this box. Sometimes antiviruses by default block access to the microphone for all applications except the system "Phone".
In addition, some memory cleaners can forcefully close processes that use the microphone, considering them suspicious activity. Add VK to the white list (exclusions) of your optimizer to prevent automatic unloading of the service from memory during a call.
Hardware problems and microphone testing
If all software settings are checked, permissions are granted, battery restrictions are removed, but there is still no sound, the problem may be hardware. The microphone is a physical hole that can easily become clogged with dust, dirt, or pocket lint. On many smartphones, the main microphone is located at the bottom of the case, next to the charging connector.
For diagnostics, try recording a voice message in any other application, for example, in the standard “Voice Recorder” or via Telegram. If there is sound there, it means that everything is in order with the hardware, and the problem is solely in the settings or an application bug VK. If the recorder is also silent or records silence, most likely the microphone is physically defective or dirty.
Carefully clean the microphone hole with a soft toothbrush or dry cloth. Never use sharp objects (needles, toothpicks), as you can damage the membrane or push dirt even deeper. Also check if the phone is wearing a case that blocks the microphone hole - such cases are not uncommon when using non-original accessories.
⚠️ Attention: If after cleaning and testing in other applications the microphone does not work, do not try to disassemble the phone yourself if you do not have experience. Contact the service center to replace the module.
Frequently asked questions (FAQ)
Why did the sound disappear after updating VKontakte?
When updating the digital signature application or its version, security requirements may change. The Android system perceives the updated application as “new” in the context of some rights and resets them. Go to the permissions settings and grant access to the microphone again.
Is it possible to allow access to the microphone only for one specific chat?
No, in the operating system Android permissions are granted for the entire application. You cannot configure microphone access selectively for different conversations within VK. Either the application always has access (or while in use), or it does not have it at all.
What if the “Allow” button is grayed out?
This may mean that access is blocked at the device administrator or corporate profile level. Also check to see if Guest mode or a restricted user profile is enabled, where access to the equipment is prohibited globally.
Does Do Not Disturb mode affect the operation of the microphone?
Do Not Disturb mode itself does not mute the microphone, but it may block the sound of calls and notifications. However, some custom firmware has advanced settings for this mode, which can limit the background activity of applications, which indirectly affects the stability of the connection.
Why can I be heard in a video call, but not in a voice message?
This indicates a software glitch in the media recording module within the application. Try clearing the application cache Settings → Applications → VK → Memory → Clear cache. If this does not help, reinstalling the application usually solves this problem.
