My loud speaker is crackling, tried several repairs, what to do now?

After accidentally dropping my Samsung Galaxy s4 in water, the loud speaker has been making a very annoying and loud crackling sound anytime it is used. After searching for fixes, I have replaced both the loud speaker and charge port. It is still making the noise! Any suggestions on what it could be and how to fix it, or am I just screwed?? Thanks!

Answer this question I have this problem too

Is this a good question?

It may be the problem of motherboard when you have replaced the loudspeaker and charging board.

Did you find a solution?

I have changed the speaker and the problema persist.

Now I have bought the charge port, I hope it Works.

But if doesn't work I'm up.

I won't change the mainboard.

Update

In my case, the phone was accidentally wet with water, and only in the speaker area. However I was using it for a few hours before drying it and may have been damaged

Fortunately, the sound with headphones is good, so I hope it "only" be the charge port.

Tomorrow I'll upload a video with the sound because at this moment I don't have a camera to record.

Can you record it for me so I can hear it?

I have same problem on my S4. I believe your Audio IC is broken.

Here is the video with the crakling speaker

The crappy mic camera captures electrical noise in high frequencies, but you can make an idea of the sound.

To me, this speaker sounds like if it was reproducing the cpu activity from s4.

Exactly the same problem as mine.

If you have tried replacing the external speaker (attached to the mid frame) and replaced the charging dock then the fault now is the audio IC

in most cases reflowing the chip can fix these issues.

Have you reflowed your audio ic?

How?

Not yet, I'm away so haven't had a chance to try it but the phone was absolutely destroyed so I don't think it will work (when I bought it the glass was peeling off the LCD) and the mid frame was bent but when I opened it up the logic board looked fine. Cover up the components near the Audio IC and then heat the Audio IC up with a heat gun

Ok thanks I will try it.

Hello,

I believe I am facing the same issue as you saraccox and I have made some progress. My GS4 loud speaker was making this terrible hissing sound when a battery was inserted, it didn't even need to be powered on.

The issue has 99% disappeared, there is only a small pop every now and then when the loud speaker wants to make a sound effect like opening the contact screen, etc.

I fixed the issue by opening up the device and cleaning the motherboard with 99.9% isopropyl alcohol. I focused on the audio chip where I saw some corrosion with a magnifying glass, I also cleaned the back housing gold contacts that belong to the loud speaker and the charging ports gold contacts that connect to the loud speaker.

Hopefully this reaches you and helps you as well.

Same happened for me. Ony i did not drop my phone in water. I had wet hands and water sipped into the speaker while i was holding it.It went really quiet and made rattling sounds. It worked fine after drying. Using it now to listen to music :D

Same problem with GS3. Got wet near speaker, now hissing and crackling. Even without being powered on. Frustrating and battery draining. It even does it when the battery is completely dead. So after reading the comments, I think I will clean the motherboard with alcohol, clean any corrosion I may or may not find, and go from there. Although, I am in the market for a GS4 or GS5.

a drop, literately a single drop managed to get to where the galaxy s5 back contats are (the ones where the flip cover connects) http://www.gokrnet.com/items/VV/V8/KV812...

And the drop somehow managed to get from there to the Qualcomm WCD9320 audio codec

https://d3nevzfk7ii3be.cloudfront.net/ig...

I cleaned it up with absolute alcohol and let it dry for 10 minutes, the qualcomm chip is very hot and i have the same issue, static whenever a sound is reproduced. Also, on boot, the output to the speaker is 1.2volts steady. Once i start reproducing anything it starts bouncing (1.2 - 0.3 - 0.1 - negative voltage - 1.2. etccccc) If you have already replaced the charging flex and the speaker the only solution is to replace the audio codec or the motherboard..

oh, also wiped cache partition and didnt worked

Oh, also wiped cache partition and didnt worked

Seeing as you've replaced the speaker and the I/O board I would have to say that it sounds like the audio codec needs reflowed on the board. You'd need flux and a heat gun to fix that, and no a hair drier isn't going to cut it.
