Microphone issues (Siri, dictation & more)

I have an iPhone 6 plus with iOS 8.1.3 and recently I discovered that Siri can't hear me when I am not using a headset.


Unless I scream in the top microphone (near the flash) she doesn't register anything at all, and when I do she can't understand me anyway. The sound wave is moving all the time even when I am silent. With my headset plugged in Siri hears me fine and the sound wave is flat when I am silent. Filming with the camera on the screen side of the phone also behaves the same way, I have to be very loud for it to pick up anything but low static.


Filming with the back camera is producing clear sound which is louder when I speak close to the top of the phone, so the hardware is fine for the top microphone. Likewise the bottom microphone is working fine with google voice search in the "Google" app, the feedback on the screen shows more indication of sound when I am speaking into the bottom end of the phone.

Dictation doesn't work at all.

Voice messages in iMessage doesn't work at all, static here too.

FaceTime works, most of the time.

I have gotten FT to work with both front and back camera as well as with audio only. But sometimes it goes into the same kind of audio bugs where there is only static and you have to scream to make it pick up any sound at all. I think it is using both microphones. Voice seems to use lower microphone for phone mode, and upper for speaker phone. I can trigger something similar to the "bug" by being loud close to the upper microphone in speaker phone mode. But it resets back into working again if I am silent for a few seconds. It might just be an auto-level function trying to be nice to whoever I am talking to. In phone mode it does never cut off.


Snapchat only works with the back facing camera (upper microphone), just as the normal camera app.


Shazam works fine (uses bottom microphone).

Voice Memos works fine (uses bottom microphone).

Translate Voice works fine (uses bottom microphone).

Google works fine (as stated above, uses bottom microphone)


Since both microphones are working in other apps it seems to be software related. And it is only failing in some apps (Siri, dictation and iMessage voice messages, and sometimes FaceTime). Don't know if it started with iOS 8.1.3 as I almost always use my headphones, but I haven't noticed it before now.


I thought it might be a glitch in noise cancellation, but disabling it under Accessibility doesn't make Siri work.


I have tried turning Siri on and off again, changing all Siri settings (one at a time), restarting my phone, resetting my phone (10 seconds of holding down both the sleep/wake and the home button), resetting all settings. Nothing has made any difference yet. Any other suggestions?

iPhone 6 Plus, iOS 8.1.3

Thanks, good to know. The info I got from the store where I bought it and from the workers at the Apple Store led me to believe that dropping it is "careless handling" and any damages to the screen voids the warranty since I can't prove that the issue was there before the drop. The man at store where I bought it said that if it is not fixed by any Apple approved repair service warranty is also void, which makes sense.


Replacing the screen shouldn't make a difference since other things might have gotten damaged as a result of the drop too. In this case Siri didn't work with the internal microphones prior to the drop, but I can't prove it for my device.


Soon off to the Genius Bar. Hope they can do anything, but I doubt it. I'll report back later.

After disable Siri, Voice Control works fine. So, its not a microphone problem. Even because in another apps (like Google Translate, Shazam, YouTube, etc.) works as has to work.


I believe that the problem begins when you pair some device in your buletooth. This troubleshoot begins with me after did that.


And really s.u..c...k...sss!!!. Right now, Apple launched Siri in Portuguese (Brasil). I wanna try, but these feature only works in my iPad, because microphone doesn't work in my iPhone!!!


And the most impressive is that have many of threads like this in Apple Fóruns and the company just do NOTHING to fix this anoying bug!


Sad, sad. Apple ins't the same anymore...

Hey ! I hope everyone is doing well. Out of nowhere, I had the same problem happen to my mic. iPhone 6 Plus, iOS 8.3. My phone was in my pocket while i was seating, and sometimes I clean my screen my spraying cleaning solution on it - so the sweat (or cleaning liquid) could have gotten inside the microphone in the earpiece (next to the front facing camera) and disabled it. To test this, try recording a front facing video with sound. If it works, then its not the microphone inside the earpiece. If it's very low, static-like, fuzzy, or not working at all, its the mic. I tried tapping it with my finger to no avail, and then I took my phone, held it normally and tapped it against my thigh a couple times... it WORKED! AT FIRST, it made the sound a little better. Then I did some more taps and it fixed it. I can't tell, however, if the sound now has more "Hiss"/white noise than before, (like in all videos...there is that Hum") but over all it sounds much MUCH better. I believe it is back to normal.

Don't break your phone people!

I am having this EXACT problem. After I updated as well, I started having this issue. Google search picks up dictation just find. Siri can't anymore :/ My front mic can't do anything. My back mic works just fine. I dropped my phone and it has some scratches(a few months ago) so I doubt mine can be replaced 😟 I really hope they update iOS...

THIS DID IT! Thank you for helping with this problem. I hate that most people on the forums want to be a know it all when they really don't know anything about the problem. They always give the token response to soft reboot, hard reboot, restore from backup, restore as new.


EVERYONE HAVING THE PROBLEM - hold down the home button for Siri and as it is listening thump the bottom of your phone with your hand (like you are giving it a spanking, lol), just a few light slaps should do it.

EVERYONE HAVING THE PROBLEM - hold down the home button for Siri and as it is listening thump the bottom of your phone with your hand (like you are giving it a spanking, lol), just a few light slaps should do it. This is an intermittent software problem caused by iOS 8 screwing up the calibration on the phone. Apple will not acknowledge problems like this, only fix it with an update when they feel it effects enough people.

I have the solution, so I was having the same problem and I was getting worried so I was screaming into it and heard the faint noise of my voice and I tried even blowing in to it and nothing seemed to be working. I was getting very angry. So I started hitting the microphone by the camera multiple times with my finger and after probably 10-15 times of hitting the microphone I tried to go on my camera and FaceTime and Siri and Oovoo and it has seemed to work. I recommend trying it and let me know how it works.

Hi
I had the same problem, I've contacted apple customer service an they was trying to fix it online, but they failed,

so after that I've been asked to bring my iPhone to one of their salons,

now I have to wait 3-5 days, guys there told me they will fix it as it's still under apple warranty,

so I'll post again after I receive my iPhone back.

Oh my God. This worked for me.Thank you soooooooooo much. 🙂 I was so upset and was thinking about getting a new phone but you saved my wallet!! People, if you have static when you record a video using the front facing camera, Siri doesn't understand you or voice dictation for text messages doesn't work. Slap your phone on your thigh or the palm of your hand really hard(not so hard that it shatters). I slapped my phone on my hand 5 times really hard and it worked!!! Siri works now and so does dictation and no static when using front facing camera. I know it seems silly but try it. IT may save you a trip to the Apple store. This is why I love forums. So much valuable information.
