Take the phone back to the seller .
Hardware fault .
jje
Yeah, I think it's a hardware defect. Is the phone in warranty? If so, just send it into a service, otherwise give it back to the seller, and ask the money you payed for.

In call Sound crackling/distortion in receiver

I purchased the Samsung Galaxy S4 GT-I9500.
I'm facing a crackling/distortion during calls.
I got my handset replaced twice. My 2nd and 3rd handset after replacement also face the same issue.
I have given my handset again for replacemnt.
Anyone facing the same issue?
There's a crackling/distortion during calls at max volume.
+1
I have noticed that too. Beyond a certain sound, there is cracking sound. Happens on Airtel Network.
Yup!!!!!!!!
Same here. More audible when you hear the ring back tone. its like some thin film vibrating over the speaker.
btw I am on airtel too
Same here, when having a call I can hear a crackling sound, it's minor but somehow annoying. Right now I'm not worried but I'm thinking about how it might become a bigger problem in the future.

Are you airtel too? My collegue has an s3 on airtel.. high volume has the same effect on it.. on 75-80% of the volume its fine

Best time to test it is while dialing 121 customer support number on full volume

I have tried many I9500s and all have this problem.

Take it from me, it is normal.. my colleague who has the S4 told me that he does not have this problem. I personally checked it and realised that the problem is actually there.. but only some of us notice it.. keep the volume above 3-4th level and you should it be fine..

There is a new update on galaxy s4 india today. Update it and see if the problem has reduced. I feel it has reduced but it could just be a placebo effect..
Sent from my GT-I9500 using xda app-developers app
i'm using MEA f/w and still have the crackling sound, but it's much better when using "clear sound" setting
Same here.. with clear sound enabled it it greatly reduced.

Fixed on MF3 :good:
Sent from my GT-I9500 using xda app-developers app
I can also confirm that samsung has fixed the problem. I am using MF8.
I don't think this is a software issue, but a hardware one.
I disassembled an S4, I unmounted the earpiece speaker. It comes attached with 2 more sensors.
I made a test call with the back case disassembled so I could press with my finger against the earpiece speaker and the crackling noise dissipated away.
Its like by pressing on it the vibration of the speaker was limited and it sounded pretty normal at max volume.
As a workaround, I inserted a piece of low density foam (found in many packaging boxes) between the earpiece and the front speaker grill and the distortion appeared again, but fainter, after I mounted the back case (speaker assembly) and tightened the screws. Indeed, like others said, its best heard when ring tone is playing when calling someone.
The earpieces is found for $3 on ebay as spare parts, maybe I'll try a new one.
I really hope its not a Samsung design flaw. Check the pics. Thoughts?
I'm pretty upset. I paid a lot of money for this phone, it has a problem and I don't like to send it to service to get it raped by some uncaring hands. I would like to have it changed, I hope its not going to be a difficult process as many things are in my country after you pay the money. How hard was it for you to get it changed?
Has this issue been treated in other threads on the internet?
Little offtopic: the best in call sound experience I had was/is with Blackberry Bold series. They have a clear sound, crisp, no distortion, even with a little bass. Sounds solid. Too bad is that limited.
The problem is with Adapt Sound!, disable it in sound settings [Call Sound] and everything should be fine. Hope this helps:good:

some of my friends have this phone and it only happens to mine for some reason. maybe a faulty handset?
it sounds like the vibrator part inside the phone is faulty does it vibrate when phone is on ?
Sent from my GT-I9505 using xda premium
the phone is perfect apart from that noise.
although i did notice if i shake it it does vibrate for no reason.
but yes i think the vibrator is faulty or something inside is loose
The camera can make that noise if it is having trouble focusing, does your camera work OK, can you tell what part of the phone the noise is coming from?

I also have the same problem - I tried looking for a software solution, but I always come to a hardware solution
even tried flashing stock ROM again, after trying everything possible with WANAMLITE ROM (1.7) - which works great on my father's S4.
going now to the service center - will let you know what they say
Thank u
Sent from my GT-I9500 using xda app-developers app
OK
so after fixing this problem at the service center I can assure you one thing - it is a hardware problem.
I didn't have the guts to open my new phone myself, so I went to a lab - he changed the ear speaker in 5 minutes and it works. if you want you can buy it on ebay - it should cost around 10$ and do it yourself - that's the only way to fix it

[Q] Sprint S4 Speaker Volume Increase Program / Mod??

Have googled and searched here and while I can find some volume tweaks, I have found nothing that works with the sprint S4. My hearing sucks and even with hearing aids it is sometimes a stretch.
Does anyone know of any program or mod that will actually work on the rear speaker? Viper for Android appears to only work on headphones or audio output?
Thanks in advance
Thanks to jovy23 http://forum.xda-developers.com/showthread.php?t=2293133 ...it increases stock volume, if you cant hear it after this you have a problem...lol...
Just flash in recovery
