Microphone Not Working on Android? 9 Fixes That Actually Work (2026)

Mic not picking up your voice on calls, WhatsApp, or a voice recording? Before anything else, do a 15-second test: open your phone's Recorder app and speak into it. If the recording comes out clear, your primary microphone is working, and the problem is more likely a permission, a connected Bluetooth device, or a specific app rather than the phone itself. If the recording is silent too, skip ahead to the system-wide and hardware sections below.

Quick Diagnosis

What's Happening	Likely Cause	Try First
Works in Recorder, fails only during calls	Connected Bluetooth device set as call audio input	Fix 4 — Disconnect Bluetooth
Works in Recorder, fails in one specific app	App-level permission blocked	Fix 2 — App permission
Fails in Recorder too — nothing picks up sound anywhere	System permission, physical block, or hardware fault	Fix 3 — System-wide access, then Fix 5
Worked yesterday, stopped after an app or Android update	App bug from the update, or a reset permission	Fix 9 — Update app/Android
Sound is muffled or quiet, not fully silent	Physical obstruction — case, dust, screen protector	Fix 5 — Check for obstruction

Test Your Android Microphone First

Before working through any fixes, confirm if this is a hardware problem or a software one — it saves time and points you straight to the right section.

1. Open the built-in Recorder (or Voice Recorder) app
2. Record 10–15 seconds of yourself speaking normally
3. Play it back

Clear Recording: Your primary microphone is working. The problem is more likely related to a specific app, permission, or audio routing — check the diagnosis table above for your exact symptom and jump straight to that fix. If you're not sure which one applies, Fix 1 (restart) is a safe general starting point. Silent or very faint recording: this points to a system-level or hardware issue — jump to Fix 3 and the hardware section near the end.

If your mic issue started around the same time your phone got noticeably hot or sluggish, it's worth checking Android Phone Overheating as well, since background performance issues sometimes surface alongside app-level bugs.

Why Is My Android Microphone Not Working?

Common causes include a revoked app permission, a connected Bluetooth or wired device holding onto the audio input, another app already using the mic in the background, dust or a case blocking the microphone opening, or, less often, physical hardware damage from a drop or liquid exposure.

Fix 1: Restart Your Phone

It's the obvious one, but it's obvious for a reason, a stuck background process or a temporary glitch in how an app is holding the microphone often clears with a simple restart, since it forces every app to fully close and re-request permissions on launch. Power the phone off completely, wait a few seconds, then turn it back on and immediately retest with the Recorder app or the call that was failing before moving to anything more involved.

Fix 2: Check App-Level Microphone Permission

If the Recorder test came back clear, this is the next thing to check, especially when only one app is affected.

Steps:

1. Long-press the app's icon → App info
2. Tap Permissions
3. Tap Microphone
4. Set it to Allow (not "Ask every time" or "Don't allow")

Check this for the specific app that is failing. If WhatsApp calls are silent, check WhatsApp's permission — not Phone or Recorder.

Fix 3: Check System-Wide Microphone Access

Some Android versions have a master microphone toggle that can override individual app permissions.

Steps:

1. Settings → Privacy (or Privacy and security)
2. Tap Permission manager → Microphone
3. Confirm it isn't disabled device-wide

On Android 12 and newer, a small green dot appears in the status bar whenever an app is actively using the microphone. If it never shows up when you try to use the mic, the app isn't reaching it at all, which usually means a permission block.

Fix 4: Disconnect Bluetooth Devices and Check Wired Headsets

This often points to Bluetooth or another connected audio device routing the call through a different microphone, a common cause of "mic works fine everywhere except calls."

If a Bluetooth earbud, speaker, or car system is currently connected, Android can route call audio, including the microphone, through it instead of the phone's own mic. If that device's mic is muted, faulty, or too far away, the other person hears nothing, even though your phone's own microphone is fine.

What to do:

• Turn Bluetooth off completely and test the mic on a call again
• If you use wired earphones, unplug them and check the headphone jack for lint or moisture, a stuck sensor can make the phone think headphones are still connected
• On phones without a headphone jack, check Settings → Bluetooth and disconnect or forget any device you are not actively using

If calls work normally with Bluetooth off, the connected device is the more likely cause.

Fix 5: Check for Physical Obstruction

Most Android phones have two or three microphones, typically near the charging port, near the camera, and on the earpiece. A thick case, a misapplied screen protector, or built-up lint can partially or fully block one of them.

• Inspect each microphone opening under good light
• Clean gently with a soft dry brush, avoid anything sharp or wet
• Remove the case temporarily and test again

If the audio is muffled rather than completely absent, this is a likely cause.

Fix 6: Close Background Apps That Might Be Using the Mic

Another app or service may already be using the microphone in the background, which can interfere with the app you are trying to use. Recording apps, meeting apps, and games with voice chat are the usual culprits.

Steps:

1. Open Recent apps
2. Close anything that could realistically be using audio — recorders, meeting apps, games with voice chat
3. Try the mic again in the app that was failing

If your phone has been generally slow to respond lately on top of this, a broader look at What's Slowing your Android Down may be worth it too.

Fix 7: Test in Safe Mode

Safe Mode temporarily disables third-party apps, which helps confirm whether another app, not the one you're testing, is causing the conflict.

How to enter Safe Mode (steps vary by brand):

• Pixel / most stock Android: Press and hold the power button → long-press Power off until the Safe Mode prompt appears → confirm
• Samsung: Press and hold the power button, then long-press the Power off icon that appears on screen until the Safe Mode prompt shows up
• Xiaomi / Redmi (HyperOS): Power off the device completely, then power it back on and hold Volume Down as the logo appears
• If none of these work on your model, search "[your phone model] safe mode" — the exact method varies enough across brands that it's worth confirming for your device

Test the microphone in the Phone or Recorder app while in Safe Mode. If it works normally there, a third-party app is likely interfering — restart normally, then uninstall recently installed apps one at a time to isolate it.

Fix 8: Clear Cache and Force Stop the Affected App

An app's cache can occasionally interfere with how it accesses the microphone, without producing any visible error. This is a similar pattern to what causes some Apps Randomly Crash on Android, a corrupted cache quietly breaking normal app behavior.

Steps:

1. Settings → Apps → select the app
2. Tap Storage → Clear Cache
3. Go back and tap Force Stop
4. Reopen the app and test

Avoid Clear Data unless nothing else has worked, that resets the app's settings and, in some cases, removes locally stored content.

Fix 9: Update the App and Android Version

An outdated app version, or a mismatch between an older app and a newer Android build, can affect microphone access. This tends to show up after an app hasn't been updated in a while, or right after an Android OS update changes how permissions are handled.

• Update the specific app from the Play Store
• Check Settings → System → Software update for a pending Android update
• If the issue started right after an update, check the app's Play Store reviews — if other users are reporting the same thing, a patch may already be on the way

Bonus step if nothing above works: Reset app preferences via Settings → Apps → three-dot menu → Reset app preferences. This clears conflicting permission and default-app states device-wide without touching your data (photos, messages, and app content are unaffected). Menu wording varies by brand — on Samsung it's sometimes under Settings → General management → Reset.

Brand-Specific Notes

The exact menu names vary by Android version and phone brand, but these are the common paths:

Brand	Where to Check
Samsung	Settings → Apps → [App] → Permissions → Microphone. Also check Settings → Privacy → Permission manager
Xiaomi / Redmi (HyperOS)	Settings → Apps → Manage apps → [App] → Permissions → Microphone. Also check the Security app → Permissions
OnePlus / OPPO / Realme	Settings → Privacy → Permission manager → Microphone
Pixel / Stock Android	Settings → Privacy and security → Permission manager → Microphone

When Is It a Hardware Problem?

If the Recorder test at the start came back silent, and you've gone through the system-level fixes above with no change, hardware damage becomes more likely — especially if the phone was recently dropped or exposed to water.

How to test further: Speak close to each microphone opening individually while recording. Some phones use a secondary microphone mainly for noise cancellation rather than primary audio capture, so a weak signal from one specific opening isn't automatically a fault — the primary mic (usually at the bottom, near the charging port) is the one to focus on. If there's no input at all from the primary microphone, consistently, across a restart and Safe Mode, it's worth having a technician inspect the microphone component.

When to Get the Phone Repaired

If all the following are true, the issue is most likely hardware, and further software troubleshooting probably will not help:

• The Recorder test stays silent, even after a restart
• The microphone still doesn't work in Safe Mode
• Microphone permissions are already enabled, system-wide and app-level
• Bluetooth and wired headsets are fully disconnected
• You've checked for and ruled out a blocked or obstructed microphone opening
• The problem started right after a drop, or exposure to water or moisture

At that point, a professional inspection is the appropriate next step rather than continuing to try software fixes.

Frequently Asked Questions (FAQs)

How do I test my Android microphone?

Open the built-in Recorder app and record 10–15 seconds of speech, then play it back. A clear recording means your primary microphone is working and the issue is more likely app- or permission-specific. A silent recording points to a system or hardware problem.

Mic works on speakerphone but not during regular calls. What's wrong?

This can happen when a connected Bluetooth device or wired headset is being used as the call audio input instead of your phone's own microphone. Turn off Bluetooth and make a test call — if it works normally, reconnect the Bluetooth device fresh or test it with a different source to confirm it's the cause.

Why can't people hear me on Android calls?

The most common cause is a connected Bluetooth device or wired headset routing call audio away from your phone's built-in mic. If that's not it, check the specific call app's microphone permission next.

Why is my microphone not working after an Android update?

Updates occasionally reset individual app permissions or introduce a temporary bug. Start by re-checking the affected app's microphone permission, then check for a follow-up update to that app in the Play Store.

Why is my microphone not working in any app?

This suggests a system-level permission block or a hardware issue rather than an app-specific bug. Check system-wide microphone access first, then test with the Recorder app in Safe Mode to rule out third-party interference.

WhatsApp voice messages are silent, but Phone calls work fine. Why?

This is an app-specific permission issue rather than a system or hardware problem. Check WhatsApp's individual microphone permission under App info, and if it's already allowed, clear WhatsApp's cache and test again — a similar cache issue can also cause WhatsApp Messages to Fail to Send.

Does a phone case block the microphone?

It can, particularly with thick cases or ones where the cutout doesn't align well with the microphone opening. Remove the case and test — if the mic suddenly sounds clearer, the case is the cause.

Google Assistant or Gemini isn't hearing me but calls work fine. What's different?

Voice assistants use their own microphone permission, separate from Phone or messaging apps. Check Settings → Apps → Google app (or Assistant/Gemini settings directly) → Permissions → Microphone, and confirm it's set to Allow.

Final Thoughts

Test with the Recorder app first, it tells you in 15 seconds if you're dealing with a software issue or something more serious, and that one step points you straight to the right fix instead of working through all nine in order. Most cases come down to a permission or a connected Bluetooth device; hardware damage is worth considering only after Safe Mode and a full restart have both failed to help.
