Poor sound quality

my D2 has a new bug, it is a buzzy sound in the background while speaking on the phone(not freehand/laudspeaker) - like there is a dust?(huge paticles of dust) on a speaker's membrane
Q1: is there any disassembly guide with speaker removal included?
Q2: does anybody know the price for a new one?
thanx

I had this problem when i first bought my D2. Above a certain volume there was a buzz sound, got a new one sent and that fixed it . Sounds like the speaker is blown i think. Isn't it under warranty still?

How to: REPLACE INCREDIBLE BLOWN SPEAKER

>>>>>>>>>>>perform at your own risk / will void warranty / I nor xda-developers will not be held responsible for any damage to you, your grandmother or your phone<<<<<<<<<<<<<
i siad it was coming and here it is. i couldn't find a video online for this so i decided to make my own. i take apart at least 100 phones a week and hadn't taken my phone apart yet so here it goes.
the nokia 6300 speaker is an almost identical replacement speaker for the incredible. for 2.99 with free shipping you can get this and fix it yourself. since i hate having to send my phone away just like the rest of the world. any questions comments or concerns let me know. here is the link to the ebay seller and the youtube video. i hope you enjoy.
EBAY SPEAKER LINK

my grandma is already broken.

Nice I may just do this just to clean the camera lense its loaded with dust.

Thanks for the vid. The instructions worked great. Got speaker and tools for $2.99 shipped.

Great vid, I clicked on the link and it said it was removed. Any other way to buy this speaker?

I was able to get the parts from "global parts direct" or something had to order at least 5, but the total came out to around 10 dollars.
Replacement went smoothly and I'm still wondering what caused the speaker to blow out.

thanks, this is a great post
now if we could only find a good UPGRADED speaker for like $5 that would be sweet lol.

Does the nokia speaker have the same audio quality or what?

I was just thinkin the same thing.

I'm not sure how to describe the sound from the nokia speaker, but I feel like it makes my phone pulse more when sound is playing. It still as loud, but it still sounds better than a blown speaker.

did this and now phone cant find a network? wifi and everything else work fine
tried putting in old speaker and going with no speaker.
any help?

Is there a significant advantage to buying the Nokia speaker over the Incredible replacement speakers that you can also find on eBay? Aside from price of course. My speaker just blew and replacing the speaker beats buying a new phone, especially since the only replacement phone I'd be able to afford would be a disappointment after having an Incredible.

[Q] Really quiet microphone. Normal?

Hi guys, I didn't see anything posted here about this so maybe it's just my phone, but does anyone else seem to have a quiet microphone? People are telling me they can barely hear me. I notice this issue on all ROMs including stock, and even though I have the phone NV unlocked for AT&T, even the sound recorder app is playing back my audio at a low volume.
Has anyone else experienced this? Is there any fix (software or hardware)?

If you have taken the phone to the gym and sweat or simply haven't cleaned out the mic area that will probably fixture issue. I took the phone to the gym a couple times and my fiance couldn't hear me afterwards whatsoever. Cleaned the mic and all of as back to normal.

Hmm, well the mic area looked clean to me, but this was a pre-owned phone I bought from Swappa so I'm not sure if the previous owner did anything. In any case, I called some friends and they said they could hear me fine. I don't know if cleaning the mic did the trick, because using a voice recorder app it still sounds low, but as long as other people can hear what I say, I'm fine with it. Thanks a lot for your help!

Glad it's working better.. let me know if it persists and I'll do some more research.

I recently snagged an M from Craigslist. The phone is in pretty much brand new condition, not a scratch on this thing, the guy even threw in a brand new Otter Box case for it. It works great, except for the terrible mic quality. No matter who I call, they all complain about the quality, whether I have 5 bars of 4G or not. I've downloaded a few voice recorder apps, and they seem to record in fairly reasonable quality, so I'm not quite sure what the deal is. I've been looking for any reference to poor mic quality for the xt907 for a few days now and this is one of maybe 3 threads on the topic. So obviously it's not a very widespread issue. But I'd still like to be able to use my new phone without resorting to Bluetooth or a wired headset.
Does anyone have any experience with this issue? Or replacing the actual physical mic inside the phone? I've found replacement parts here and there, but they all just say 'XT907 Replacement Mic" etc. If someone has an actual model/part number for the microphone, or know where to find it, I'd greatly appreciate the info.
For the OP, when you cleaned your mic, how exactly did you go about it? I've hit it with compressed air but I haven't taken the phone apart yet.
Thanks again for any help.

Compressed air would probably work, I just blew into it to clear any dust, and I tried to take a small microfiber cloth and insert the corner into the mic piece just in case there was any extra dust, though the mic hole was pretty clean to begin with.
I mostly had the problem when I called my dad though, and I found out the problem was a problem with the earpiece in the Droid 2 Global that my dad was using. When I switched him to an older Sony Ericsson w518a, the voice still seemed a *tiny* bit quieter than I think it should, but by no means was it as bad as with the Droid 2 Global.
tl;dr: I pretty much came to the conclusion that the earpiece of the other person was faulty, not the mic of the Razr M.

I also have the same issue with the outgoing voice quality of the Razr M. After a lot of researching I have come to the conclusion that it is actually the Noise-Cancelling feature of the phone that is not tuned correctly or outright defective on some devices. The secondary mic is located on top of the back camera. If you try to cover it completely with tape or something rigid, the voice quality improves somewhat.
Since the default phone application is the only one that seems to utilize the noise cancelling feature, it also seems to be the only one that suffers from horrendous outgoing voice quality. All my other apps that use a mic, like Viber, Voice recorder and VoIP apps, do not have this problem.
There is no way to disable this feature, on some phones it's a simple toggle but not on the Razr M with JB. I know of other mods where it can be disabled in the Phone.apk by disassembling it and removing the lines of code that way, but I have no knowledge of doing that. If someone is able to shed some light on this process, please help us out.

Problem with noise suppression, nothing else. Try to remove second mic from the board.

LG G2 D802 Has terrible sound quality from earpiece, which part do I replace?

G2 D802 terrible sound quality from earpiece, which replacement part?
Hello!
I bought a used D802 for around $95 yesterday. Screen and everything in perfect shape, almost too good to be true, right? Well, turns out the sounds quality is **** during phone calls. Called my dad yesterday and the earpiece speaker just buzzed as soon as he talked louder than whispering.
I looked up how to replace the earpiece and it doesn't seem too difficult and I already ordered a kit of tools for that from DealExtreme. However, I need to find a new speaker too. Etradesupply has way too expensive shipping to Sweden so that's not an option.
Another option is ebay, where I could get one including shipping for like a 10th of the price compared to buying from etradesupply. But how is the quality? Will it be just as bad as my current earpiece or will it actually sound better?
Does anybody have any experience with this?

Thought I'd post an update. I bought a cheap speaker from Ebay and I also bought some cheap tools from Ebay, or maybe it was from DX. Changing the earpiece took maybe 20-30 minutes using a video guide I found on youtube. Sound quality is great and has been working great ever since I swapped it. Would definitely recommend!

A possible fix to low in-call volume

Recently I found my Z3c had a dramatic drop in earpiece volume. I could barely hear the caller's voice when in a quiet surrounding (like office or home), and impossible to follow the talk when outside. This was quite annoying, because it's a phone and making calls is one of its essentials regardless of whatever extra functions added to it. So I did a lot of work trying to bring the volume back. I rooted the phone (eventually), tried some sound mod, and even worked on the mixer_paths.xml directly. None of these gave me any luck. As the problem seemed irrelevant to the software flaw at the stage, I was thinking about possible hardware cause.
The first thing I did was to open the top side flap, which covers the micro SD and USB. Then I made a call to my voicemail and compared the voice I heard from both the flap opening and the top speaker. I could tell immediately that the sound was much louder and clearer from the flap opening, while the sound from the top speaker was distant and isolated. Wait a sec...
From my research on posts, I was told that there is a film lying on the speakers to make the Z3c dust proof. You can see them through the speaker cuts. To allow the sound goes through it, the film has to be perforated. Could those tiny holes be blocked after spending time with dust, water and soap (yes I did wash my Z3c frequently, thanks Sony for the water proof!). A user did mention the volume on both speakers were much gained after removing those films. I don't want to go extreme, but that did give me a hint.
So I used a pair of tweezers, with pointed tips. I slightly scratched them on those films. Immediately the color changed from dark black to lighter gray. I kept scratching them and made the grey evenly, and made another call to the voicemail. Guess what...the earpiece volume was noticeably increased! Then I airbrushed those films and tried again, this time I could not tell the improvement, but the sound was loud enough that I could hear the voice even from a distance. Now the sound coming from the flap opening would also match with that from the top speaker. I would call it a success.
To summarize: what I did was simply cleaning those meshed films on the speakers, by scratching dust off them. These films can be penetrated if you pushed too hard, so please be gentle. And I'm not sure if this trick would work for others, I'm just sharing my experience, with a good wish that this could work for others who are also bothered by the low in-call volume as I was. Still, try those software fix as well, as the cause to the same phenomenon may be different.
Thanks for reading. Let me know your comments/thoughts/tricks and treats (Happy Halloween!)

Thanks for sharing, I have same issue --- did you test its waterproofing if it still works after cleaning the speaker's mesh?

Has anyone issue with the lower speaker? I actually tried to touch it, its very hollow --- are all units like this? Thank you.

done, so far great improvement with sound, i can hear the other person on the phone better --- but not sure about my bottom speaker, its very hollow.

This was one of the reasons why I'd sent in my phone. I thought the speaker was broken. Seems they've just cleaned or replaced that mesh because the volume works well on the returned phone.

Thanks for sharing :good::good:

I push chewing gum in to the grills and mic to clean them out.

wow.. it realy works... thanks a lot bro ... !!!

Thx for sharing I'll try it

How does such a thin layer of perforated material manage to block so much sound?

You're my hero!!!!!
I was about to send it back cause of the awfully low earpiece volume. Now that I have cleaned it it's even too loud!
Thanks mate I really appreciated it
Cheers:good:

Great tip bro. Immediate improvement to volume level. However I guess I pushed it further that the sound is now cracking at high volume when the phone rings.
But am still happy that I can hear the other party.
Good job man.

Those of you who are claiming this works, could you please go into your service menu (*#*#service#*#*) from your dialer and run the stereo speaker test? Do both speakers have the same volume output or is one significantly louder than the other?
Sent from the only flagship phone that actually fits in my hand... The Sony Xperia Z3 Compact

So, I'm almost embarrassed to report that I had no issues with my earpiece, but thought I'd give this method of "cleaning" it out a try. I used a piece of chewing gum to remove any dirt from the screen and almost immediately noticed a drastic DECREASE in output from that speaker. Now, calls sound hollow and tinny, and the stereo speaker affect is nearly gone because the top speaker is so much quieter.
I'm afraid that I somehow caused my top speaker to produce less sound by trying this method. I've tried to wipe away any sticky residue caused by the gum, but nothing seems to help. I can't send my phone back to Sony because it's been rooted and they wont honor the warranty. I can't believe that thin piece of speaker grill would actually be able to block sound. What now?

I managed to get higher volume by cleaning the upper speaker with a chewing-gum but my operation removed the thin grey layer. Do you think I've lost waterproof?

No you haven't. Speaker attached to the lcd panel by a plastic staff so water can't goes inside.. I removed the speaker cover too but i admit without that cover phone looks ugly

OK, thanks.

Has anyone tried replacing both speakers with Z3/Z3 dual/Z3+ ones? I was looking at the pictures of spare parts and it might be possible to put some of those in our Z3c, since the sound on Z3c is really low by default, and the ones on Z3 do sound quite louder.

I had same problem, could barely hear a phone call. I scrapped off the black material protecting the speaker now I can hear through the earpiece. I'm guessing now the phone is not water proof..
