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?

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 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

Most of the answers say change the connector or whatever but my question is to change it how much will this cost, and/or where would you go to get this done? Contact me @ savanabae.icloud.com please

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.

When I call out to a friend via my iphone, it crackles while it rings, so I hang up. It is the strangest thing. Not sure yet how to fix this problem.

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?
