[Q] Speaker distortion/crackle - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all,
I want to keep this simple and short as possible.
Galaxy S4 I9500 -32GB. Android 4.2.2 with the 400 mb update installed.
Ear Speaker has faint, but somewhat annoying tinny/crackle noise.
Loud Speaker even more so, extremely bad at high volume.
Tried movies, no crackle from loudspeaker.
Tried music, no crackle from loudspeaker.
Tried other phones on same network, no crackle/distortion noise.
*I need to mention that it does not really sound like distortion, but more like poor DAC or compression?
*This crackle/tin/mild distortion only seems to occur during voice calls.
I've only had the phone for 3 days now, I need to know if this is a software issue or is it OBF?
I could say i'm being fussy about the ear speaker, but for a brand new phone at this price; it's unacceptable.
Should I install Android 4.3?
Thanks a lot

Hissing external speaker on end of call

Hello
I have an HTC Vogue and when I end some calls, I notice the external speaker makes a loud continuous hissing noise. When this happens, no sounds (ring noises) come out of the phone. I am fairly technical with phones, so if you need more information, I would be happy to oblige. I am running the latest ROM from HTC 3.03.651.4.
Thanks

[Q] Handset Speak Distortion

I hope this hasn't already be posted, I looked hard.
I've recently upgraded to the official 2.2 release, then replaced the kernel with the vodoo kernel to address the lag issue. Now when I use the handset for calls the callers voice is distorted. There is a tinny rattling like sound. Kind of the distortion you hear in the low bass range when your stereo is to loud, but this is distortion in the higher ranger, not low bass sounds. Happens at any volume level.
This doesn't happen when using the speakerphone, or ear piece, just the normal ear speak in the handset.
I'm looks through the Service Menu->Sound->Handset options but not really sure what all the setting ares.
Any help would be very much appreciated?
Thanks
John
I would flash one of the custom kernels or....... you could try galaxy tuner it allows to to equalize the sound. Worth a try
Me, I would just get one of the great roms already out there

[Q] Earphones Mic too low volume

From Day one i have been trying to get good earphones with Mic for nexus 4
tested out more than 6-7 quality earphones with mic like J6M, Klipsh, etc
but the microphone volume on the other end of call is too less compared to apple ear phones( recently switched from iphone)
I have to keep the mic piece really close to my mouth for a good conversation...
can someone help me here.. the mic on nexus 4 works perfect but when i connect earphones the problem begins... i used mic sensitivity apps to test and they pick very less volume from the connected mic
How do i boost the mic sensitivity on earphones or should i return the phone

I'm having the exact same problem - did you find a fix?
I tried quite a few.. expensive as well as cheap ones. finally i got hold of a cheap ear phone set and the volume to the other end is good to be heard (as I have been reported).. While trying them all, I was calling my friend and asking him.. so thats how I know i picked the best one. However, since it extremely loud.. i kinda have to keep it away from my ear a bit and volume on phone is turned down to minimum.. Plus, due to its sheer loudness, I can hear the buzzing sound.. For the first time i noticed it, i.e.: through these extreme loud ear phones. The other party hears it too. Never heard it while on call directly using the ear piece. Strange.

Do you mind me asking which brand headphones you are referring too here? I have the same issue.
I bought from a local shop. It was a knock off of beats audio. The sounds it throws is EXTREMELY loud.
Is it just me, or does the OP make very little sense? I'm completely lost at what he's trying to ask.. Something about the mic? or the sound output of the "earbuds"?
No trouble here with any of the wired earbud sets I've tried. Clear as a bell and no buzzing.
If its so Loud for you, what are you not adjusting the volume? Would kinda of make sense to do so...
Or you could upgrade in your tech and get a bluetooth earbud.. I have absolutely no problem with volume levels from my Jawbone; I'm hear clearly and I can hear them just find (even when driving with all windows down, it sounds like they are right next to me yelling)

Nope, it's you. OP was referring to the mic volume on the headset being low, but in filthykids response, he mentioned that the headphones that solved the quiet mic is also very loud on the earpieces.
Also having the same problem, BTW.

i9500 speaker crackling at high volumes

Hello,
I was wondering if anyone else is experiencing this problem with the phone's speaker. When listening to music or on loudspeaker, my speaker crackles horribly. I just noticed his problem within the past month. Can someone point me to where I can buy a replacement part for this speaker so that I can replace it. To clarify, at first, I noticed the speaker crackling at high volume, but on some videos and songs, I get crackling at even medium volume.

I don't have that problem, but I have seen it in many devices, not just this one. It is possible to blow out the speaker by simply driving it too hard. It may be something you could replace, but I can't imagine it would be extremely simple to do. A rule of life for electronics is that they shouldn't be operated at 11 unless you are a member of Spinal Tap.

Speaker Buzzing

Hey everyone,
My 6P seems to buzz like crazy when I play anything at max volume. Is this a defect? The speakers are still loud and clear but buzz like crazy when I'm around the last 2-3 notches of the volume slider. Obviously loud speakers can cause resonant vibrations but this seems kind of excessive and with everyone talking about how great the speaker quality is I can't help but think that some thing may be up. I'm coming from HTC One (M8) Boomsound speakers and my impression from the 6P's are that they really aren't that great.
I'm having similar issues. I notice it easily when changing ringtones or notification tones. I wonder if this a problem with a gain setting or a QA issues affecting a small number of phones. I'm on MDA89D build.
I had a buzzing speaker problem too then I looked at the EQ on my google music and for some reason it was set funny. I flattened out the EQ to take some bass out and now it doesn't buzz.
The problem actually occurred more with games rather than music. I RMA'd and things appear to be all good now.
