iphone 6 mic not working

Okay. I've got everything but front facing video, Siri and text dictation to work. I know the speaker works because it works with other programs/apps and with voice control

I recently started having this problem too. I thought it was my phone's hardware.

After reading through this entire board, I realized that some apps that use the microphone seem to be forcing the microphone to the video mike. Apple needs to fix that. After turning off the microphone for snapchat, my microphone began working correctly again. If I want to use the microphone on snapchat, I have to go into settings, allow it, then when through, disallow its use of the microphone. I went through each program that accesses the mike and tried turning it off and calling my partner to see if the sound was working right. Snapchat was the one that re-routed the mike to the one by the camera. I would suggest anyone frustrated with this issue try this first. Go through each app that accesses the microphone, turn them off one by one and test with a patient and willing partner to find out which one is causing the problem. I see a lot of people saying this is a hardware issue and it's possible there are two issues. If people can't hear you at all, no matter what, then maybe that's a hardware issue. If you're like me, and suddenly, shouting as loud as you can into your phone to talk to someone becomes a problem, try my remedy. It might work. I suspect there is more than one app that re-routes the microphone but I've seen Snapchat mentioned several times in this forum.

hello! better not waste your time! find a free time to go to apple store and tell them your problem! if you tried to restore and it's still the same you're encountering a faulty mother board

Siri and Voice text doesn't detect my voice anymore in iPhone 6. I didn't expect such mic failure for the legend Apple Company. iPhone 6 is my first Apple product.
Please help me to solve problem asap.

worked for me until I can get to apple genius bar.

Nope. still the same

I have the same mic trouble.How can i solve this my self?

i did this 3 times and nothing changed, so this doesn'tfix anything

It didn't solve my issue.

thank you so much , I didn't even realize there was a microphone on the back .

I have had this same issue over several iphones. I received a replacement phone and I even bought a new phone to address this. I tried all of what was referenced below but the only fix that seems to have worked is to turn off the bluetooth when not using is. The bluetooth seems to interfere with the speaker phone.

This is the second time this has happened to me with an iPhone 6, they replaced my screen and it fixed it, but they said it shouldn't happen again, yet here I am, woke up this morning and it wasn't working. This just ticks me off and it's frustrating don't have an Apple Store by me in Idaho, luckily I'm in California for break, so luckily I have an Apple Store near, but still i don't think there is gonna be a Genius Bar appointment before I leave. I've been a loyal apple customer since 04 in 4th grade, but this is terrible

I had same problem for a week until I turned off bluetooth. Hope its as simple as that for you...

I took mine to the Genius he said there was nothing he could do and said I could have a like for like replacement for £300 ish

That's one expensive microphone
