Sound problems during voice calls messages or video calls is one of the most common complaints from messenger users. When the other person can't hear you, and you see a crossed out microphone icon or just silence in response, this instantly disrupts communication.
In most cases, the Android system already contains all the necessary drivers, and a physical connection is not required. However software conflict or broken privacy settings can block the application's access to the hardware. Let's take a look at why WhatsApp the microphone does not see and how to fix it in a couple of minutes.
Below we will consider in detail the algorithm of actions from simple checks to complex resets. Follow the instructions sequentially to eliminate hardware malfunctions.
Checking the physical connection and basic condition
Before getting into the jungle of settings, make sure that the device is functioning correctly at the system level. Sometimes the problem lies not in the messenger itself, but in a blocking level operating system or a hardware failure.
Try recording a voice note through the standard voice recorder of your smartphone. If the recording turns out clear and loud, it means that the microphone itself is working, and the problem is localized in the settings Android for a specific application. If the recorder is silent or records noise, it is worth checking the case or protective film.
Often users do not even notice that the thick case blocks the bottom hole of the microphone. It's also worth inspecting the speaker mesh for dust or lint that could be muffling the sound. Gently clean the holes with a soft brush.
⚠️ Attention: If the microphone does not work in any application (camera, voice recorder, calls), the cable inside the case may have come loose or the module itself may have failed. In this case, software settings will not help - a visit to the service center is required.
Setting access permissions in Android
The most common reason for no sound is the lack of permission to use a microphone. In modern versions Android (starting from 10 and higher), privacy policies have become much stricter. When updating an application or system, access rights may be reset.
To regain access, you need to go to system settings. The path may differ slightly depending on the phone model (Samsung, Xiaomi, Pixel), but the logic remains the same. You need to find the application management section.
Go to Settings → Applications → WhatsApp → Permissions. Make sure the switch next to Microphone is active and lit blue or green. If it is turned off, the system simply ignores any attempts by the application to capture the audio stream.
- 📱 Find the application in the list of all installed apps if it is not on the main settings screen.
- 🎤 Check if the “Ask” mode is not set every time", this may cause failures during quick calls.
- 🔄 If the switch is already on, try turning it off, wait 5 seconds and turn it on again.
☑️ Checking access rights
Sometimes a complete reset of rights helps. Turn off all permissions for WhatsApp, force stop the application through the settings menu, and then start it again. At the first call, the system will again request access - confirm it.
Diagnostics of conflicts with other applications
A microphone is a resource that in standard mode can only be used by one application at a time. If you are trying to make a call to WhatsApp, and there is a voice recorder, voice-controlled navigator, or another calling application running in the background (for example, Viber or Telegram), a conflict may arise.
The Android system simply does not know which process to give priority to, and blocks audio capture for the second application. This often happens if you minimized a video call but did not end it, or forgot to stop recording.
Close all background applications through the multitasking menu. Tap the square bracket button or swipe up (depending on your navigation type) and swipe all app cards. After that, try making the call again.
It is also worth checking whether the Do Not Disturb mode or special sound profiles are activated, which may limit the microphone in certain usage scenarios.
Clearing the cache and updating the application
Accumulated temporary files can lead to incorrect operation of communication modules. The cache WhatsApp sometimes contains outdated configurations that conflict with the current version of the operating system.
Clearing the cache will not delete your correspondence or media files; it is a safe procedure. It only affects temporary files that speed up startup. To do this, go to Settings → Applications → WhatsApp → Storage.
Press the button "Clear cache". Do not confuse it with the “Clear data” button, as the latter will delete the entire correspondence history and require re-registration of the number. After cleaning, reboot your smartphone.
| Action | Impact on data | Recommended frequency |
|---|---|---|
| Clear cache | Safe, messages are saved | When glitches occur |
| Updating the application | Safe, adds functions | When a new version is released |
| Cleaning data | Deleting all history and account | Only with a complete reinstallation |
| Reinstallation | Requires a backup copy | In extreme cases |
Make sure that you have installed the latest version WhatsApp from the official store Google Play. Go to the store, find the application and click “Update” if the button is active. Developers often release patches that correct compatibility errors with new versions of Android.
What to do if the update is not in the Play Market?
Sometimes the update does not arrive automatically. Try clearing the cache of the Google Play Store app itself in your phone settings, and then check again for updates for the messenger.
Specific settings for different manufacturers
Smartphone manufacturers often add their own add-ons to Android that can aggressively manage power consumption. Brands like Xiaomi, Huawei or Samsung can “kill” background processes of the messenger to save battery, which leads to the microphone being muted during a call.
You need to add WhatsApp to the exception list or allow auto-start. In the MIUI shell, this is done through the “Security” application → “Permissions” → “Autorun”. B One UI Samsung should check your battery settings and disable application-specific optimization.
Also check for “Game Mode” or “Game Turbo”. If the messenger accidentally gets into the list of games, the system can block the microphone or redirect the sound to the headset, even if it is not connected, thinking that you are playing.
⚠️ Attention: Energy saving settings interfaces are constantly changing by shell developers. If you haven’t found the exact item, look for sections with the words “Battery”, “Optimization” or “Launch applications” in the settings of your smartphone.
Aggressive energy saving is the main enemy of stable communication. Be sure to disable battery optimization for the messenger.
Reset and reinstall
If none of the previous steps helped, the application configuration files may be irreversibly damaged. In this case, a complete reinstallation is required. But before this, it is critically important to make backup chats.
Go to the settings of WhatsApp itself: Settings → Chats → Chat backup. Click "Backup" and wait for the process to complete in Google Drive. Without this step, you risk losing your entire chat history.
After creating a copy, delete the application from the device. Reboot your phone, download the latest version from the store and restore the data from the copy on first launch. This action reinstalls all system bindings and drivers inside the application.
- ☁️ Make sure that the Google account to which the copy is being made is active and has free space.
- 📶 To download the backup, you will need a stable Wi-Fi connection.
- 🔐 Remember your phone number and verification code for login.
In rare cases, resetting all network settings helps. This won't delete your photos or contacts, but it will reset your Wi-Fi passwords and Bluetooth settings. Path: Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings.
Before completely resetting the phone, try connecting a wired headset. If the microphone works in it, but the built-in one does not, the problem is precisely in the hardware of the main microphone of the smartphone.
Why can’t I be heard only in voice messages, but everything is ok in calls?
This may indicate a software error in processing audio files specifically in the message recording module. Try clearing the application cache. Also check if the “Noise Reduction” mode is enabled in the call settings, which may not work correctly when recording.
The microphone works, but the sound is very quiet and muffled. What is the reason?
Most likely, the microphone hole is clogged with dust or dirt. Brush it gently with a toothbrush. The second reason is the use of a cover that blocks the sound. Remove the case and check the recording quality.
Can you use an external microphone for WhatsApp on Android?
Yes, if your smartphone supports connecting USB microphones via an OTG cable or has a 3.5 mm jack (supports headsets with a microphone). The system will automatically switch audio input to an external device when connected.
Will updating Android help solve the problem with the microphone?
Yes, if the problem is caused by a bug in the current version of the operating system. Check for updates in the Settings → About phone → System updatesection. New patches often contain audio driver fixes.
