iPhone 6s - Call interferance making calls impossible.

[Omega Mac]

iPhone 6, purchased in Nov 2015.

During voice calls the other end is experiencing really bad distortion or interference.

What happens is I can hear at very low volume what sounds like GSM interference. The kind you get and goes; da da dada dada da da da da da da (older audio equipment or guitar amps often pick up the sound. Nokia even used the phenomenon Innone to advert)..... Once I hear this I know the person on the other end is possibly hearing the same but at a dramatically higher volume or plain distortion of my voice. To the point calls end as its impossible to continue. Sometimes it distorted for the other end without hearing this sound also .

I also have another iPhone 6 purchased a few months later. This does not suffer the same interference problem. If I need to continue the call I use this in the same environment and location and the call is perfect every time.

The phone is under warranty and also extra apple care and I will revert to this.

However I wondered had anyone experienced the same problem?

To my mind it's as if some hardware or software shielding has failed.

Have you tried resetting network settings?

No. Is the simple answer and thanks for the pointer as I had not considered this!

I used the apple software to transfer android device settings and content to iPhone and it just worked. Used the same procedure with the other iPhone.

I'll give it a go. It's worth doing I guess.

To update. I reset networks on iPhone. I made a test call to a landline that wouldn't answer so I could listen to the plain connection but of course a ring tone, but the ring tone leaves enough space between beeps to hear how clean the connection might or mightn't be.

There was another type of sound I heard which I had noticed before but forgot to log in my opening post. It's a low level crackling and static basic type noise. Similar when you haven't tuned into a FM or AM station perfectly on a manual dial radio. It's very low in my ear but clear enough. I'll try a call later today as it's late here and see how I get on.

Also to note I have lost connection to 4G and the phone seems only to have established a 3G connection.

One thing to try:

Go into the cellular -> LTE settings and make sure it is set to data only if you are having voice issues.

Voice over LTE has caused numerous issues for my relatives, friends, etc. Muffled sounds, distortions, etc. All on iphone 6s. Apple's answer when they called is that voice over LTE sometimes works, sometimes doesn't, and may work for one phone but not another, etc. Basically their support staff has no idea why it is acting up.

Thanks but I don't see that option.

Cellular is also now renamed Mobile Data. I'm on the latest version if iOS.

It's possible this got worse after the last upgrade and possibly the one before, but I can't be totally sure. Clutching at straws in this one.

November 2015 means it is under warranty. If you can reproduce that problem in different places, then you likely can reproduce it at an Apple Store. So you make an appointment, show them the phone with the problem, get a new one. Problem solved. Make sure you backup to the cloud or to your computer before you hand over your phone.

(I once returned a faulty product under warranty, then looked it up on the internet just out of curiosity, and there where tons of people trying everything you could think of to solve the problem without success, when I fixed it by handing it over to a sales assistant and getting my money back. Plus I immediately used the money to buy a newer model

Direct sale from Apple.

No Apple Store in this country. Which is ironic if you know the country.

I do intended to send it back if it continues as it's causing serious problems. Other than that it's hard to fault the phone thus far.

I guess I should wipe the phone before sending it back. I have it backed up via iTunes.

Photos to back up all the other media.

Might there be anything else?

Anything like Cellular (or Mobile) Data Options?

It might be as simple as getting a new SIM card. Ask your carrier for a new one.

To update this thread. I got a replacement phone from Apple. So far so good. A very quiet earpiece in comparison.

I also had Applecare and was entitled to express swap out so that was nice.

However under statutory rights where I am I was entitled to refurb, replace or money back based on manufacture decisions without Applecare, but I would have had some days without a phone. So that was a bonus.

The primary reason I took out applecare is because it is the only way I know to be sure if you ever break your screen that you get an actual Apple iPhone replacement part. The statutory warranty cover in my location would be superior to the US and other market and you would not need it ut if you were out of warranty and screen breakage is not covered by warranty you would have to pursue an apple repair specialist or other 3rd party where I am.

Many repairs shops may use 3rd party screens as apple screen are the most popular for 3rd party to knock off since Apple make so few models they are prolific, or so I was told by a screen supplier to repair shops. I have also heard form people they felt the repaired screen they got didn't seem to last as long as the original and was too broken eventually but more quickly.

Two incident cover on Applecare remain intact as I requested they not use the Applecare cover as it was covered under statutory. It's important to be clear depending on where you are.
