iPhone 5 making cracking popping static like sound that distorted the audio every time I would send or receive voice message and it also would make the noise every time I tried texting. I fixed it like this.

Settings

General

Accessability

Phone Noise cancellation- turn off

Then reboot

The cracking sound disappeared on my phone and it started working fine.

Hope this helps

Sounds like a problem with the mic on the dock connector that used during calls

The upper mic is used to record in voice recorder

Replace the dock and see if this sorts it

iPhone 4s with same issue. I solve it by holding in the power button and back button together and power off and keep them pressed till apple logo appears. This resets the phone and all is good now

I am having the exact same issue, Replaced the doc connector and now sometimes it will be fine, and sometimes it will still crackle. If I turn on speaker mode and turn it back off during the phone call it will resolve it temporarily. I have also replaced the actual ear speaker.

Any further advice?

I have the same problem. Only mine started right after my iPhone was left sitting out during a dust storm. It has to be dirt in the mesh of the speaker. Can I somehow replace the mesh?

I work at a mall kiosk where we've repaired too many to count.What I found not sure if it helps but I had the same issue with the crackling noise. What fixed the issue for us turned out to be the charge port connector. It turned out since it was a new charge flex we replaced since the connector when they're new doesn't have as much give or hasn't been broken in. What I noticed is that it being stiff it caused the connector to slightly become raised/lifted from the connector. What I did was not put the sticky part underneath the flex cable down onto the mobo and simply connect the cable. Voila it all worked no static. Happy customer, hope this helps

Hi Have had the same issue on a 5c , replaced screen and top speaker and still the same but on further examination we found a screw had come loose and attached to the magnet on the main speaker causing feedback

this turned out to be what my problem was. I opened the phone and as i pulled up the screen a screw fell out. I figured out where it went and also cleaned out the speakre mesh while i was at it and now the phone works fine.

SOLUTION - After all that has been said I would like to suggest the most common cause of this issue. This issue will regularly occur when the charging port flex connector is replaced. In this case the crackling may be caused by a grounding problem between the top of the charging port flex connector and the metal screw panel. The top of the connector must be insulated from the screw panel that secures the ribbon cable onto the logic board. This can be accomplished with a small piece of electrical tape.

Same here. A caller hears crackling during the ringing before I even answer. I want to know if replacing the lightning dock assembly worked.

the loud crackling in from blocked speaker .... sound can't exit so the sound is bouncing off of clogged mesh..... all you have to do is change the mesh that the speaker is facing and its fixed. I changed the speaker but noticed when i tried to make a call it echoed but when i had the phone open and speaker slightly slanted not pushed down it sounded clear so i checked the mesh and it was clogged and full of filth after that it sounded clear.

Change the mesh or remove the mesh and test connection this isn't hard ware lol this is simple clogged mesh that sound cannot escape

The earpiece of my 5S is crackling for some time. I replaced the earpiece but still no luck. Trying to understand what you mean by "change of remove the mesh". can you be more specific?

I just replaced the screen of an otherwise working i5S, and got a crackling/distortion in the earpiece after reassembly. Replaced the earpiece speaker but no change.

Discovered that the sound was fine when the screen was "loose", on top of housing, before pressing it inside the frame. So apparently something is being "jammed" when putting it together.. Cant see anything "abnormal", and have tried cleaning all contacts etc...

What could possibly cause this i wonder..?

Hi, I think I have the same problem. Changed the earpiece but no change.

Also I had a struggle puting the new earpiece back. The small frame that holds the earpiece in place is popping out and the larger screw is not screwing.

Have you solved your sound problem?

I have the same problem with brand new iPhone 6 plus, facetime and third party call app works fine only with cellular network i hear the static sound, I've tried every reset/restore. Apple dealer did hardware diagnostic and everything tested fine. SIM card woks fine on other device. So my guess it has to do with intervention between earpiece speaker and antenna. I had no accident with my phone, and it was working perfectly for 4 months before this happen. any advice? I tried changing speaker and cleaning the mesh, not working!!

I accidently found that twisting the phone in a certain way makes the sound disappears. it works for sometime but recurs again shortly after. I checked all connections are secure, it must be broken connections! I am thinking of changing the charging port connection.

의 답변

Interestingly enough it has been about a week now that I have been facing a VERY similar situation with my iPhone 6.

SIM card has been tested on a different phone and it was proven to be fine (meaning the issue was with my phone and not the service provider). Calls that are going through the mobile network either are full of loud crackling sounds which can be heard at both ends or are fully silent (meaning no sound goes through at both ends of the call) and this is true whether I use the phone set, speaker phone or headphone.

Everything else that makes use of the speaker and mic work (Whatsapp, Camera, Wifi-Call, Facetime...).

Where you able to find a fix?

Very late to the crackly iPhone party, but I thought I’d share my experience for people having similar issues (and seeing as this thread seems high up in Google’s search.)

I’m running an old iPhone 5c. The screen broke, so I replaced the screen, swapping the earpiece and camera out from my old one, and replacing the ropey old battery while I was in there. Put the phone back together and everything was working fine except for making calls where there’d be the most annoying static, crackling, modem noise. Sounded like it was badly grounded. Also I found that the phone would heat up excessively during calls (-only calls, not during any other processor-heavy task).

Tried a hard reset/restore but still had the same issue. I could receive calls fine on speaker phone but not through the earpiece speaker.

In a final act of desperation I removed the screen from the motherboard and unscrewed the metal earpiece assembly on the back of the new screen. While I was doing this I noticed that one of the thin insulating foam pads on the back of the proximity sensor ribbon cable had slipped/perished slightly and so it had been touching the back of the metal cage holding the earpiece in place. I cut a new square of electrical insulating tape to cover the exposed metal patch on the cable. I also noticed two exposed patches of metal behind the connectors on the two ends of the cable that connect this cable to the motherboard, so I cut tape to cover these too. I reassembled the phone and tested a call. Beautifully clear speech with no crackles and the phone stayed cool to the touch. Sweet!

This photo shows the cable as I initially found it, without the new insulating tape on. Above photo is the exposed metal that I believe was causing the main problem. Bottom photo shows the exposed metal on the back of the two motherboard connectors that I covered for good measure.
