Pop/Crack sound from speakers when dialing from iphone 7

Im experiencing the same exact issue @ my iphone 7.

Sadly the workaround with the disable-enable "noise cancel" did not work. Though i didnt try that in conjuction with the "erase network settings".

Also i noticed, that if you 3D touch smt in the home screen, in a quiet environment, the earpiece-speaker enables and emits a low static sound as well which stops after ~3 sec's..every time

As suggested by the support guys, i tried resetting my phone, and setup as new, but did not work, in my case

Now my phone is in the service center and awaiting news from their side.

Follow these steps-

Keep a USB 2.0 cable handy

Have your Pc or Mac next to you

Plug in your iPhone 7

The iTunes application window would pop up in case you have a Mac or you would require to open the iTunes App if you have a Pc

It would prompt you to download iOS 10.1.1 again build 141B50

Do as it says

You would be fine

Sadly, my phone came back from the official Apple service center here in Greece, with no work done on it. They cannot identify the problem..

It's kinda tough to reproduce, since it only happens at the first call , after the phone is locked with the screen turned off. You can reproduce it again if you let it sit 1-2 mins, and then attempt a call.

Tried also the Noise cancellation trick, definitely lowers the popping sound but its definitely still there. When i try to "reset network settings" so i do not miss that feature, the problem comes back sadly.. so no lack here with that trick.

The support center already resetted my phone to the latest iOS which obviously didnt work. Also as i've written before, when i 3D touch, i can definetely hear the top earpiece firing-up, with a same popping sound, which fades away as well.

My wife's 7, doesnt make that sound as well as one of a colleague of mine.

I m kinda stuck here.. any other suggestion or help, will be greatly appreciated!

I have the same issue. Have you been able to find a workaround with noise cancellation turned on? Let me know. Is this definitely a software bug?

Bump - anyone else?

Did you ever find a solution to this?

Just trying to get a confirmation if its a hardware or software issue.

Cant conclude if it's a hardware or software issue. The problem hasn't been resolved sadly...with either of the solutions provided.

The service center cannot reproduce the issue, but its still there persisting in every call.. The "twitter-Apple" support guys have redirected me to the service center again, but i aint gonna go in all the fuss.. 1000Euros to the trash bin

I ll just swap the phone with my wife's 2nd workhorse, 6s which currently in 9.3iOS is noticable faster than the 7.. go figure!

I have accepted, that i bought a lemon which also has been affected by a peeling paint issue (matte black) in THE CASE without a single drop..

Apple quality products .. expensive lesson, learned though.

Same issue here, iPhone 7 Plus, its not 100% repro but its pretty annoying, especially when the speaker volume is up, it pops, how did this get through their testing ?

I have the same issue. iPhone 7 32 GB black

Same thing here. Bug is still present in iOS 10.3 beta 3. Apple should let us know if is software or hardware related.

How is it with iOS 11?

No this is not a solution. What it does, after the hard reset it turns noise cancelling back to off. That is why you can’t hear the crack sound.

The problem still persist in ios 11 GM. I have the iphone SE 32 GB
