iphone 6 mic not working

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

Did they charge u some amount for replacement

Loud speaker problems the other side voice can't recived
