It seems to have fixed itself by updating the applewatch last night. that is the only thing that has happened between it not working yesterday and it working today. But I was same, made phone calls through the car handsfree, on speaker, on mic itself, in coming and out going calls no sound, not even the ringing noise when calling out. fingers crossed it doesnt happen again.

I’ve tried some of the solutions suggested here and even reset my iPhone after the temporary fixed failed with random crackling or nonexisting sound reappearing. Now, after 30 reboots or so, the phone doesn’t pick up my requests. I hit numbers I want to call and I have a 15 second lag before the call is placed. 4 out of 5 times I have no sound, except from speaker mode, and after talking a minute that fails too. I don’t see how this could be a hardware problem because the phone has worked without any glitches whatsoever previous to the OS update and there isn’t even a slight possibility I damaged it.

Mine seems to be working OK now, not great but OK. I have gone through the network provider and need to use the wifi calling where possible. But my service provider is not as good as it is suppose to be, so getting out of contract. is it possible the new update requires a higher level of signal for calls now? is the new software slightly too advanced for the older models (even the iphone 7 and se)? just throwing ideas out there I am unable to answer these questions and am certainly not saying these are the issues. is this happening with the newest model aswell? but the top corners of the SE are not very responsive in the touch screen anyway, so not getting another SE.

I also have this problem. iPhone 6 that worked fine on iOS 10. Moved to iOS 11 and the phone audio issues immediately showed up along with a whole bunch of other performance, stability, and battery life issues. Upgraded to 11.1 and the performance and stability issues improved (still not as fast as 10, but usable). However, the phone call audio problem persists. Upgraded to iOS 11.2 beta last night and it worked for a few minutes and then returned to the same behavior. I also did a system reset and the issue still persists. Please fix this APPLE!

I installed the IOS 11.2 Beta, the sound problem still persists, but at least now I can use my earphones to listen to music and FaceTime, when I upgraded 11.1.1 I was left with no music and FaceTime was no longer an option. The issue hasn't been fixed altogether but spending a couple of days without music was terrible. I hope Apple fixes the problem for good soon!

I've gone to 11.1.1 on my 6s+ (waited a couple of weeks before going to 11, but have uploaded the "fixes" promptly because of so many issues). It's got worse.


I can't hear Siri or any notification alerts.


Calls are ok when on speaker or Bluetooth, but otherwise I can't hear the other party (they can hear me).


I was about to buy my 1st ever Mac (after PCing from the days of MS-DOS & Mainframes with 128k memory & punchcard interfaces), but I feel Apple are going off the rails. Mind you, considering a WindowsPhone makes my testicles retract.

I still keep hearing about peoplearound me experiencing all or some of the issues reported in this thread. Especially irritated about how kids from my son’s school can’t take or make calls. It’s not like their parents are deciding it’s early Xmas for a new phone and if they do, it won’t be a six.


What’s funny is even though my own kid has very low battery life and all sorts of glitches on his seven, he still talks about X. Not going to happen.


I’m now using an old six from work with 11.1 installed, because I had to, and even if very laggy, at least it works. My seven is still laying around waiting for that “future” “magic” update. As far as X goes, not going to happen here either.

Thanks but this is not a very helpful reply. It asks you to test your mic restart the phone! I think there is a fundamental problem with the iOS 11.1.2 upgrade. It works on my 6S but has stopped the mic from working on my 6. Only the speaker and headphones work.


Can we get someone from Apple to urgently address this issue, its getting frustrating and there are no responses from Apple staff!

Seriously, there is a problem after iOS 11 update on Iphone 6s. The calling volume just disappears in between and the other person cannot hear anything. I am annoyed with this lately so that I have to speak my personal conversations either by shouting or by putting phone on speaker. The hearing speaker too had crackling sound issue which still exists till date.

I just tested phone by deleting all applications and reseting it. Sound problem is still there. I know it's better than it was before but it's still terrible for phone that i payed almost 900e. (iPhone 7). I think that this sound problems are reason why i did not got new iPhone. I had battery problem with iphone 6s with sound problem after updating. With Iphone 7 i had no problems till update to iOS 11. + versions. That make me to believe that maybe just maybe problem is not me. Giving 1200e for phone that might have same problem in next version of iOS is not in my plans. So i guess I'm stuck with i7 till it stop working. For next phone i might think about Android. Cuz this is really frustrating. I never had problem with calls on devices that are 10x less expensive. I don't need this.
