IOS 12.0.1 Microphone Not Working

Last Update:

After the hardware repair of the audio chip my IPhone works perfectly again.

Finally I paid 80€ and it took about 5 days to have it back. Much cheaper than a new phone. However, there are guys offering the same repair for less than 50€ but some of them seem to do the “quick fix” - just heating up the chip and not actually rebound. This might work or not .... some actually “fry it to death”. In Germany the range of cost for the exact same repair is between 45€ and more than 200€ - crazy. So keep your eyes open. Last comment: If you observe the described symptoms no software update will fix it - you will need the repair!!

Good luck :)

After talking with Apple Service and a smart technician it is 100% clear a hardware problem. As the phone is out of warranty there is basically nothing they are offering. Seems that this is a well know issue with the audiochip on the IPhone 7 that has a bad connection to the board (due to manufacturing issue, fall, whatever). The only way to fix this is to re-solder the chip - a quite difficult task. The official workshops from Apple does not do that in Germany. After some research I found a provider that offers that kind of service in Germany. However that repair will cost 150€ !!! As my phone is just a little bit older than 2 years I will do that step ...

I will report the result!

Hi all, I found the solution for this problem at least in my case. It is not an hardware related problem but a software one, because I had sound and mic on WhatsApp call, but I have screen time settings for me and my family.

I went to Screen Time settings, and the disable, deleted all screen time restrictions and finally enabled new settings.

it looks like there is some bug on settings that affect microphone and mic of the phone app

Hi Guys I am in exact same boat like u

let me tel u what happened when I took my iPhone twice in last 2 days to Apple store here.

so yest one guy tried to troubleshoot the issue and told me to reset the network settings, somehow that worked and he send me off. After 10 mins my phone again stopped working. Can’t hear anything, voice memo not working, front video( has no audio) and same with the back videos

then again I set up an appt today with Apple store, I was told by another customer support person that I have a motherboard issue which they cannot sort out. They told me I am out of warranty by 5 months and they won’t consider. I have to buy a new one. I was so disheartened as it’s not my mistake because Apple has a glitch they couldn’t fix it!!

so at last now at home I thot let me not give up on my phone, I tried this -

go to your settings - general- reset- reset all settings!! Boom sorted my issue of no audio from anywhere!

I dint lose my data or anything!

Please guys give this a shot?

Hope it sorts things out for you

I performed a backup using iTunes on my computer, then went to Settings / General / Reset All Settings. I did lose my cards in my wallet, but small price to pay to actually be able to use my phone as a phone. Seems to have fixed the issue for now.

Ended up going to Apple store where they plugged it in and confirmed that it was a hardware issue. Made claim to insurance and they replaced with a new phone with little over $100 deductible. Seems to me like a weakness of iPhone 7's soldering and is a material defect in construction and should be replaced by Apple no charge, but that's my two cents (less $100 deductible).

Post ios 12.3.1 update-- After losing my microphone so that I could not record audio notes or use the phone and trying _most_ of the solutions offered up here, I finally tried resetting my network settings on my iPhone 7 (before going all the way and resetting the phone to factory settings). The problem was resolved. At least for the moment. It appears after reading all these posts that some fixes are only temporary. NOTE: don't forget to rejoin your home/main wifi network after a network reset or else all your data will count against your data allowance because it will be coming through 3g/4g. Or, if you are like me and have really lousy reception at home, no data will come through at all!

So to fix iOS12 microphone issue , iCloud backup , then reset all in your settings ! This fixed my issue 😊

This is called an audio ic problem or the loop disease which is what they refer it too, it can be fixed if you force restart your phone then when it turns on and it’s on the apple logo sign, you hold your finger on the right bottom area of the apple logo until the phone is fully on then let go and it should work, if it doesn’t it needs to get repaired with a professional to fix it

I had exactly the same symptoms. However this hardware defect has nothing to do with the update. It is a production/quality issue. My phone was also a little bit older than 2 years and just out of warranty. Welcome to the club ...

UPDATE:

Squeaky wheel gets the grease. Continued escalating (while remaining polite but with good strong points) and I got Apple to send me a replacement. 1.5 hours on chat and the phone were worth the $800 replacement phone...

Same issue on my end... When I reached out to Apple Support and referenced the issue and the discussion forum with other folks having the same issue, they replied with this:

So unfortunately, either have the phone repaired for $319 USD or buy a new phone. Absolutely ridiculous and frustrating.

Yea I don’t see how they don’t see this as an important issue what if you need to call emergency services and it’s a life or death situation... that being said you can mail it in to professional repair techs on eBay for like $50
