iPhone X call quality issues

Hi


I seem to be having random issues with call quality. I’ve had several people now tell me that when calling them they can’t hear me or I sound like I’m underwater.


Problem is it seems to be very random.


I have tried 2 different cases (the second seems to be better) but I have also had the problem with no case on the phone.


The other day I was on a call which was fine. I got put on hold so put it on speaker and put the phone down. When they came back I took it off speaker but they couldn’t hear me. I tried tapping the back of the phone hard at the bottom and then suddenly they could hear me.


I’m now worried that I may have a loose microphone connection but I just cannot seem to replicate the issue.


I will book a Genius Bar appointment but I can’t get one for over a week so thought I’d do some back ground Work first.


Thanks in advance for any help.

Reposting earlier fix with additional info explaining why...


Verizon customer iPhone X. Same problem. Phone works great except for phone calls. I sound muffled or underwater, but only sometimes. Other calls are perfect. Tried all of the fixes in this forum - Network reset, LTE off/on, full reset, wi-fi calls off. Noise cancellation off. With and without cover. Got a replacement phone from the Apple store. None of it helped and now I know why...


The issue turned out to be how I was holding the phone. There are three microphones on the X and one of them is located by the camera on the back of the phone. Even though I didn't cover it while holding the X (with fingers and thumb on the sides of the phone, I apparently was close enough to make that mic behave differently. When I move my phone-holding position in the same grip to the bottom part of the phone, the problems vanish. I have run through a series of test with my "complainers" and this seems to pinpoint the root cause. It's either user error or a design flaw, but there is a simple workaround. Hold the phone at the bottom of the case and definitely not near the top. Problem Solved!


Update as to why this works: Apple has designed noise cancellation into the talking side of the phone. (This is different than the noise cancellation in the Accessibility settings - those are for the listening not speaking). Anyway, there is a small mic on the back of the X by the camera. It's purpose is to listen for ambient noise (think crowded bar) and to cancel that noise from what it hears from the mics on the front at bottom of the phone. Those mics hear your voice talking plus they hear the ambient noise (crowded bar). The software "subtracts" the bar sound from what it hears on the front and the listener never hears the bar noise - just your voice. (You can test this by completely covering the back mic hole with your finger - then the listener hears the bar noise and has trouble hearing your voice).


Anyway, this is a really great feature - except that if you hold the phone near the top, it channels part of your voice into that back mic and it ends up canceling out all or part of your voice. So I have to hold my phone at the bottom and things work fine. This also explains problems with folding phone cases and issues when you are holding the phone between neck and shoulder.


I sure hope someone from Apple reads this. It would have saved me a lot of time if they had told me this when I complained...

From the UK.


We’re off to the local store here in the uk tomorrow, this time my friends iPhone X screen is refusing to light up from standby when he presses the right side button, sure the phone is powered up, we know this by using the side switch and feeling for the pulse furthermore we can ring his phone, it rings but there is nothing to answer with as the screen is off, a 3 button restart brings the phone back on and all is well for a while, I say that because this is the second time it’s exhibited this exact same problem. Siri does start chuntering to himself, odd comments etc but that’s it.


When I reported this to the store on Wed 10th Jan the response was - if it happens again bring it all in for an exchange, we took a video to prove the point and will show them tomorrow.

Why am I very much of the opinion that HQ has told stores to replace customers £1000+ phones with minimal fuss in light of the ever increasing number of issues been thrown at them.


The camera on my iPhone X crashed yesterday as I went to take the video of my friends iPhone X issue, it wouldn’t focus, both cameras front and rear were totally out of focus in all different modes, with only a couple of modes working correctly, a 3 button restart bought things back to normal but not before we took a video to prove the fault with his iPad, gee life’s getting far too complicated for my liking.


Regards.

I went through the trauma of the 7 Plus poor call quality well documented on this forum, we had to move the thread to Facebook because entries were being restricted. I moved to a Samsung Galaxy Note 8 which was brilliant but I found it to big so moved back to Apple and bought a 256gb Iphone X at a good price. I bought it last week and updated to the latest IOS straight away I'm now back to the habit of asking everyone on the other end if they can hear me OK and touch wood so far all is well both during audio and video calls. Time will tell......

I’m convinced Apple have dropped the ball on quality and quality control. My 7+ was replaced due to call quality issues and the replacement exhibited the same fault. I went through all the Apple bull including you’ve restored from a defective backup reset as a new phone etc. I now have an IPhone X restored from the faulty 7+ backup which seems to be working fine at the moment at least until the next update. This disproves the garbage coming from Apple. They need to understand they’re producing defective goods and the defect has exited in 3 different models of IPhone. If the issue is the way we use them why did the call quality fault only start at the 7 series IPhone.

I’ll be the first to admit I’m a bit of a novice when it comes to the world according to Apple, my first product was an iPhone 4, amazing at the time but time moves on and here we are - iPhone X.

Since the death of Steve Jobbs someone is making a very poor attempt at stepping into his shoes, had he still been around I believe this anniversary product would have been developed 2 or 3 years in advanced its release and that release only announced once the product was working to the standard we all came to expect from him.

I believe it’s now profit before quality - “get it out there, we’ll patch it later,”

I’ve said it before and I’ll say it again “for this iPhone to be unable to perform its primary function flawlessly is nothing short of a travesty, shame on you Apple, your not what you once were and never will be, remember the boy who cried Wolf once to often.

The Apple tech I saw originally after he replaced my phone mentioned if it’s a software issue the fix will be a long time coming if ever. I don’t know. I have to go back to Apple but I am just not in the mood to stand in the store for an hour explaining the issue no one can fix. It’s probably class action lawsuit material.... selling a phone that can’t be used as a phone.
