Samsung S10 microphone not working during calls

Hello buddies, I just got a S10 but i have a weird problem during calls, when i'm talking with someone and putting the phone on my ears the person hears me far and with some cuts, but when i move it a bit or take it away of my face the person starts to hear me clearly, And on speaker call mode there is no problem. This happend on all call apps as phone dialer, viber, fb messenger... with data & wifi also. Tried a voice recording app, both microphones record my voice without any noise or cuts, so i guess the top and bottom microphone are fine. What i have already done: - Wiping data/cache/hard reset.

- Updating firmware with odin ( currently using this one CHERE ).

- Booting in Safe mode and made a normal call.

So, if someone have a similar issue or have any idea what can cause this or would fix it please help me

Check dialer settings, disable any voice related setting, and try.
If not working, probably it's of the proximity sensor, or maybe you're just covering the microphone while holding the phone?

Checked dialler settings they are fine, couldn't find any noise reduction parameter to disable it there. for the proximity sensor there is the light which blinks near the battery icon and when i put the phone close to my ear the screen turns off, is there a way for advenced tests on the proximity sensor ? And no im not covering any microphone with my hand with my hand.

Edit: tried *#77692# and the phone vibrates and screen goes green when i pass my hand through the sensor a bit slower than my previous S8 but it works fine.

The only thing i can think about is that, a third paty app is causing the problem, like voice assistant, Google Assistant? Bixby? Force stop both of those apps and try making a call. Check app permissions & locate Microphone permission, disable them all except for the dialer (phone) apps.

Good luck.

Tried that, also tried to boot in safe mode where all 3rd apps are disabled and same thing, when the phone is on my ear the voice goes low.

Is it possible that the phone detects voice as noise ?

Hello and sorry for double post,

I just realized that the phone is using the top microphone during calls and barrely the bottom one, how can i fix this, please ? Or its a hardware issue ?

Is there anyway to change microphones sensitivity ?

Hey, what did Samsung do? I have the same issue!

unfortunately I have the same problem. I have searched everywhere and nobody knows what this problem is, even in a samsung forum there are several users with the same problem without solving it.

Does anyone have updated information on this?

I have noticed that this failure happens to me when I talk lying in bed.

It seems that it captures my voice with the upper microphone instead of the lower one, that's why my voice is heard far away. However, when I make a call and stand, this problem does not happen. (This failure happens to me with calls on whatsaap)

*sorry for my bad English.

Let’s admit it, Android mic problems aren’t uncommon. Having microphone problems on your Android is definitely one of the most annoying things that a phone user can experience. Isn’t it frustrating when you’re in the middle of a call and suddenly all you hear is static? What if it was an urgent business call? What if it was a phone interview?

The cause can be either software malfunction or hardware damage. Inspect damages to your phone. Did you drop your smartphone recently? Did you install apps that can potentially affect your mic? If you didn’t do either of these things but are still experiencing problems, don’t worry. I have tips on how to fix microphone problems on Android.

7 tips to fix microphone problems on Android

1. Do a Quick Restart

To fix the microphone problem in your Android, try this simple trick first up! If you haven’t restarted your phone in a long time, now is as good a time as any. Restarting your smartphone clears any open apps, and can possibly be a quick fix to your problem.

Turn off your phone and wait for about 10-30 seconds before turning it on again. The process will refresh your system. Check to see if the problem is solved.

2. Clean Your Microphone With a Pin

This mic fix on your Android phone is simple, yet it’s super helpful. Your phone accumulates dirt from using it for extended periods of time.

Mobile phones are vulnerable to dust or small debris, and can get into the small openings of your phone. You might not know it, but tiny fabric pieces can get stuck, especially if you’re always carrying it in your pocket.

Gently poking and cleaning the mic on your Android phone might fix the problem

Your mic is a small hole beside the USB connector. You can either blow at it directly or get a small pin or a thin needle and carefully poke the hole to remove any dirt inside.

3. Disable The Noise Suppression

Some Android phone releases come with a cool feature called noise suppression/noise reduction. It reduces the background noise when you are on a call or recording a video.

However, this can be a cause of why your microphone is acting up.

  • Go to Settings.
  • Select Call Settings.
  • Look for the Noise Reduction option and disable it.
  • Restart your phone and check if the problem is solved.

Run your phone in safe mode to disable all third-party apps temporarily. Try a test call or use the recorder to check the microphone.

If it is working fine, then the culprit is within your apps. You can check the apps that are using the microphone by going to Settings -> Apps -> App permissions -> Microphone permissions.
