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...

Same issue reported by so many others. We are on Verizon, but that’s probably not it either. Different solutions seem to work for different users. Our solution, which helped a great deal, was to turn off “Calling on other devices”. How many people use their iPad to call grandma anyway? Well, it worked for us. I left noise cancellation on, and left WiFi calling on. Yes, I tried it every which way. Turn off calling on other devices.

From the UK.


Further experimentation has thrown up another result.

My friend and I, same iPhone X models, same network (3UK) made some calls yesterday to each other from the same location, the phones showing 3G and not 4G while calling, all calls were clear and easily understood.

Later in the day he was at another location some 10 miles away and called, his phone showed 4G while calling, mine showing 3G. He could hear me very clearly but his voice to me was foggy and unclear, we then terminated the call and he switched his phone to 4G for Data only meaning calls go over 3G and he called again, this time we could both hear each other clearly with no difficulty at all, my phone was already on 4G for Data only.

So it appears that keeping you phone on 3G for calls and 4G for Data is the best option for call clarity until the networks catch up and provide VoLTE everywhere instead of in patches across the country.

I have this same exact problem. Even when it connects to my car bluetooth they say I sound "robotic". NEVER had this problem and I live on my phone for work. It works great with AirPods. Go figure!


After spending $1200 for a phone, I say APPLE needs to fix this and FAST! What gives Apple??

I have the same issue with my iPhone X. Almost on every call people complain that I sound muffled or under water. Some have said I sound like I have a sore throat. I been through two Genius Bar visits so far, several resets, hardware tests and reloads of software on my new iPhone. I even had an Apple Senior IOS advisor send me to Verizon to have my phones sim card replaced. So far nothing has fixed the problem. Today, working with another Apple Senior she made my third Genius Bar appointment schedule for January 13th 2018. I never had any sound quality issues with my iPhone 6 Plus. If it wasn't for the battery life I would still be using it!

Everything you’ve mentioned... I did too. Sprint wouldn’t replace my SIM card. The tech guy told me to go back to my 6 but I couldn’t. The touch screen (although in tact, no cracks) worked only intermittently. The screen kept freezing and my battery was shot too. I don’t know what to do. The only thing that worked was I think (if I remember from the 250 things I tried) calling my aunt on FaceTime with the LTE off. But that’s not practical and I didn’t use it for more than a few min. Apple had me test call her probably 20x doing different things to improve sound quality. The Sprint tech told me it’s bc sprint doesn’t work with VoLTE.... but can’t just be sprint because other people with different providers reported similar issues to ours. I need to be able to make phone calls. And trying to get a new phone would mean buying this phone outright. I love the phone.... but the most important reason to own a phone is so that you can make calls.

If there is one thing that really irritates me, that is the fact that when you bring something like this, and previous things, to their attention the Apple store assistants have all, without fail been programmed (brainwashed) to say “we have never heard of this before, you’re the first one to bring this to our attention” as if you are a total moron dumb enough to believe them and can’t recognise when you are being lied too, you just know that they have been told on pain of being stuffed to death with 50Lbs of apples - ADMIT NOTHING. The customer is always wrong.

I am an iPhone X user on AT&T and am having the same call issues that everyone is reporting here. People say I'm garbled, I go in/out where they can't hear me on the call. It just started to happen over the past few days. Doesn't sound like there's any fixes yet to this as I read all the threads. I did turn off wifi calling to see if that works per someone's suggestion. Hesitant to swap phones and go through that process only to have it just happen again.

Open to other suggestions here, or if Apple would chime in that would be great. Thanks

Jan 11, 2018 11:28 AM in response to nhfam

Actually I found a response on this forum that helps. Set your LTE to "data only". There is a problem with 4G connectivity with the X. Some odd explanation that doesn't make any sense about 4G calls not being able to connect to 3G connections like they have for the past 5 years. Clearly it is a phone issue. But it did help. APPLE you need to get this fixed on your $1000+ phones!!

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 have tried may of the online recommendations, exchanged phone at Verizon for a new one with same problem. Spoke with apple tech support and diagnostics came up with nothing. A senior advisor came online and asked if was restoring from a backup, which I did with both phones, his advice was to try and restore iphone x to factory settings through i tunes and see if that helps. Thoughts are maybe something from the backup is causing the problem. In the process of doing that now and will update with results.


Short story - if restoring from backup and there is a sound problem try restoring phone as new and see if problem still exists.
