Damaging speaker of XDA II is as easy as 123? true or false?

Well i think its true. why? read on!
I bought my XDA II a few weeks ago. Its a love & hate machine & i won't get into that. But i think i have damaged the speaker .. as in i can notice sound getting distorted at times. It probably happened when i played this audio file at full volume .. which was actually for less than 2 seconds!! Ever since then, i can tell how the sound from the speaker comes out distorted. Same exact thing happened with my brother, where he played some song at full volume & it apperntly blew his speaker. I've soft reseted the machine multiple times (who doesn't!) ever since but no hard reset yet.
Although my question is .. is it really _that_ easy to blow the speaker?! The device should either have a speaker that can handle the amplification it is being providing, or not amplify the sound to levels the speaker can't handle. Blowing your speaker away on the first attempt to play something loud seems awfully lousy to me from a machine's design point of view.
Has anyone else experienced such problem or know of some remedy? I don't want to open the machine up & get the speaker repaired. Would really appreciate any help on the matter.
Thank you all.

Hi m8. Don't know if you've tried this but I had a problem a while ago where I could not hear any sound at all. I could make a phone call and ther person on the other end could hear me fine but I could not hear anything. I found the way to make it work again would be to squeeze the thing at the top near the earpiece (as if it was a loose connection).
Like I said, don't know if you've tried this but it worked for me. Have you got warranty?

Hey Camel, i have had my sx56(wallaby) all the way apart, and the only thing attatching the mainboard to the speaker are two little spring-loaded contacts, perhaps try tightening the screws on the back of your device (if it's anything like mine), this should make the connection between your speaker and mainboard more secure.

speaker
hey mate,
yep same thing with mine. now anything above about 50% in a phone call and it's all distorted.
pretty annoying, i've just got to get around to opening it up and checking the speaker contacts/replacing speaker with a spare.
will post results.

Microphone low sensitivity when not on speaker

I have noticed an issue that did not exist with the Galaxy Nexus.
When not on speakerphone the microphone sensitivity is down-regulated significantly from the way it is when it is on speakerphone.
Frequently people connect the phone via auxiliary cable in the car (as a hands-free approach), but in order for it to route the audio to the speakers for the car, it cannot be on speakerphone. However when not on speakerphone the sensitivity of the microphone is limited, it is not the same as on speakerphone, therefore unless you have the phone right beside your mouth, the other party will be unable to hear you (due to low volume).
I assume this is an software change in 4.2, I have tested the issue on two Nexus 4's. When turning back on speakerphone, the microphone increases sensitivity again, and the other party is able to hear clearly again.
This poses a problem if you want to have the phone in your car connected to auxiliary and not right beside your mouth/face. I assume they added this because they assume that if the phone was not on speakerphone then it would be right beside your mouth/face during a call, however this is not at all always the case, especially if you connect your phone via aux in the car.
Anybody else experienced this? Any work-around?

Yes, thats really a shame.
I think, it is the noise cancellation. Nexus One has Niose Cancellation, too.
There I've found out, that I have to make a change in the build.prop to disable this
but I really don't know, where to find the line in build.prop to disable the noise cancellation.
And: You have to root your phone to do this.
It's really a shame, I can't use my Nexus 4 in my car plugged into the auxiliary input

hmm anyone can disable it via build.prop?
reminds me a of the days in Nexus one..

I've opened an issue on Google.
Hoping for many votes, that they can see it.

Thank you so much for bringing this up. This is my main beef with the phone coming from my Gnex. Hopefully a fix can be found soon.:good:

My suspicion is that this has to do with noise cancellation. The way noise cancellation works is that there are two different microphones at opposite ends of the phone; the one farther away from your mouth picks up ambient sounds and, more faintly, your voice. The one nearer your mouth picks up ambient sounds and, more loudly, your voice. What gets sent over the phone connection is, effectively, the difference between the signals from the two microphones, leaving mostly your voice.
If the two microphones are roughly equal distances from your mouth, they both pick up your voice about equally strongly, meaning that your voice is mostly filtered out with the rest of the ambient noise. Speakerphone mode disables the noise cancellation, so your voice comes through strongly.

.... as I've said in the second post. Other phones don't have trouble with it.

Exactly. This is not simply a noise cancellation problem IMO. Other phones have noise cancellation too but don't have this problem.

Sorry for inadvertently repeating what you said in that post; it's been nearly two weeks since then, and I had forgotten it had been previously mentioned.
Perhaps the other phones with noise cancellation that don't exhibit this behavior simply turn it off if a headphone is plugged in. That would make sense for a speaker-only headphone, but not necessarily for a headphone with an inline microphone, where the voice microphone would still be nearer to you than the auxiliary microphone. If that's the case, it would be nice if that setting were exposed as a controllable option.

Please look here and add as many stars, as you all can:
http://code.google.com/p/android/is... 4&colspec=ID Type Status Owner Summary Stars
I'm the only one who has told it to google and with one star I think no one will see this problem there.
So we have to gewt as many stars and comments as possible.

Any developers can help with the build.prop line to disable this?
I remember pm founder of cyanogen mod and he pointed me the line to disable in nexus one..

I heard if you get an external mic it is much better but I haven't tried myself. This is annoying because I usually just use the aux with my nexus s with no problems >.< Anyone out there got any other solutions?

Yea seriously bump on this topic. This is a massive problem..

Have you all voted on Google page for this problem?

[Q] microphone not working

OK everything been fine with my phone until this evening. My phone comes from the 2 week delivery estimate from the Nov. 27/2012 order batch
I needed to look for a local restaurant. Pressed the mic on google search bar and it would not recognize that I was talking. Tried a few times. Then reset the phone. Tried again. Turn the phone off and on. Tried again. Downloaded a voice recorder. It recorded static but no voice at all. Downloaded sound meter. It flux between 20-30db. I then called my wife. She couldn't hear me. Switched to speaker phone and she could hear me just fine. So now I reset my phone to factory and same results.
Any ideas? I know it worked earlier because I used voice recognition to send some texts without problems. I visually checked the mic hole in case lint or smeg might have blocked it. But it's clean. Blew into it just in case too. The top noise cacellation mic seems to work picking up ambient noises according to the gray rings around the google search mic icon. But it doesn't light up red.

Same issue. I used to be able to make it work better by plugging a cable in the charging port. Now nothing.

Does anyone know if there is a way to set sensitivity of the mic? I am assuming the same mic is used for speaker phone as with every other app including phone.. Since speakerphone seems to work..

So I decided not to waste any more time and get the RMA process going before I am outta my 15 day return period.
Was quick and easy. Exchange will arrive with in 3-5 days. Return label was in my email before I hung up.

on the iphone 4s and the gs2... speakerphone uses different mic. i could be wrong, but the reason i say this is... in my iphone.. i got sand on/in my phone and was blowing it out with air compressor. i ended up dislodging the bottom mic and had to use speaker. then on gs2 the leaked roms, specifically showstock... needed noise reduction turned off in order to use bottom mic. had something to do with the 'mic swap' from international to att version. but the end game was... i had to use speaker.
as far as maybe getting it back in shape before your rma arrives... did a piece of lint or something get lodged in the mic hole?

Running a sound tester app or recording, initially it gets sound, but it seems to be static. It looks like what you are talking about with the gs2, the noise suppression kicks in and stays that way.
I really wish I could troubleshoot it before having to send it back, just to know what caused it and not repeat it on the replacement..
I looked at the bottom mic again, looked like a grain of sand. Got it out but still same results.

[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

Will try with my skullcandy's and revert

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.

Low microphone volume?

Does anyone else have the person they are talking to mention how low you sound to them when speaking on the phone?
It seems like I have a low microphone on my nexus 4, unless the phone is directly in front of my mouth the person can't hear me clearly, I'm thinking it might be hardware but I know with some phones this can be corrected with a custom driver that makes the microphone more receptive
Is there an app or setting that I can use that would disable noise cancellation in case that's what causing my mic to make me sound low?

Actually I have the exact same problem - not sure what we can do to fix it.
If I crank up the volume fully it appears to -sometimes- solve the low audio problem.

if it -sometimes- solves the problem then it might be a software bug. i hope some dev can be notified of this. have you tried a different ROM? if yes, have you notified the dev of the ROM?

Its actually on stock, so I just rooted it, and will try with a different rom shortly.

Same thing here.. Sometimes they hear me, sometimes they don't even during the same call..

I'm starting to think the noise cancellation is playing some tricks.
While driving home this afternoon I was on headset on the freeway, where those I talked to could barely hear me.
Unplugged my headset (klipsch s4 image ii), and sound was good. After a while I plugged headset in again, still bad.
When coming off the freeway I kept the headset on while talking - and all of the sudden it was crystal clear (using the words of the guy I talked to at the time). At the same time I noticed that I had no data (outside even edge coverage), don't know if that is related or not.
Is there some way we could experiment / disable or tweak the noise cancelling?
Ps: I have had the same issues without headset also, so definitely something general software things going on

I had the same setup. I am using the Xylon (stable) 15 ROM for several days now, and SO FAR I think the microphone reception is better. I haven't heard complaint from the person I speak to on the regular. *cross fingers* hope it's 'fixed' in some way.

That's exactly how my phone was as well. I would be on one call for a while and all of a sudden out of nowhere the person I'm speaking to says I sound like I'm speaking across a room and I'm like 'wtf happened? I haven't changed positions since I started talking to you!'
I did a little testing with the person I was speaking to as well, to test the microphone receptiveness and the mic seems to pickup my voice better, I wasn't speaking directly into the mic and they said they heard me fine.

I have a sneaking suspicion It might have to do with the noise cancelation as well, I think on paper whoever designed that feature on the phone thought it would be cool but it doesn't seem to be panning out too well. I've read somewhere on this forum about how to increase microphone volume and cancel the noise cancellation using the Terminal Emulator app and/or the phone's dial codes (#*#*some sumbers*#*#).
I have the same earphones (no mic attached) and I have similar experience but I haven't taken note of it like you have since 95% of the time I have my headphones in the phone.
I also want to mention a little trick that I think seems to work when on calls. Whenever I turn the phone over, screen facing opposite of me, I hear less complaints of me sounding too low to the other person. Maybe it's doning something... i dont know.

Same issue - with headset only though
I have the same issue, people really struggle to hear me on conference calls (which I spend a lot of time on), so I have to hold the mic in front of my mouth to speak which gives awful sound quality. I don't have this issue when not using a headset (phone mic works fine).
Nexus 4 + Klipsch s4a = really quiet mic, people can't hear me at all.
Nexus 4 = No problem, phone mic works.
Note - music playback is fine, no issues there.
My klipsch headphones worked fine on my GNex, no issues, so I don't think it is a problem with them. It has been an issue from the moment I switched to a Nexus 4. Have also tried other headset (samsung one that came with Gnex) - and have the same issue of sounding very quiet on the headset mic.
I did wonder if it was an OMTP vs CTIA issue, but the button on my headset works fine to answer/hangup/skip tracks/open voice search etc. so I don't think it is that.
I also tested with another Nexus 4 handset using Soundmeter and got very similar results on both handsets, suggesting it isn't a handset issue (though not a very scientific test).
Does anyone have any ideas?

Just In Phone Calls?
Hi Folks,
Is this mic issue just related to phone calls?
I'm using the latest CM10.1 nightly build and my mic is useless for phone calls.
However, Google's voice search works just fine and if I record a video my voice is recorded just fine.

I could be wrong but I suspect the Nexus4 can not use the phone jack for incoming audio.
In my opinion when one plugs a headset into the audio jack the Nexus4 camera microphone
becomes activated, not the headset one. And the Nexus4 cam mic is really bad.
Again, I might be completely wrong. (I hope)

OMG you have it reversed. What a mess!
I have yet to see Google Search understand anything I say and video sound is horrible. Call audio is great.

Hi guys - I am on stock android - same issue on 4.2.2 as on 4.2.1.
This isn't just related to phone calls, same issue on google search. I tested headset mic pickup volume when speaking normally with Soundmeter - around 35-40dB (what it calls a quiet whisper at 3ft to quiet residential area, Park).
I also tried moving the headset mic closer and further away from my mouth with the phone in the same position - with the headset mic virtually touching my lips it went to about 60 dB (normal conversation at 3ft) - so it does seem to be related to the headset mic. I can only guess it is either a dodgy connection in the handset or some noise cancelling functionality that is cancelling out my voice!
Any ideas or thoughts greatly appreciated

I knew I was an outlier.
No way I'm getting a fix for my issue then

Anyone figure out a fix? I'm having similar issues with my microphone.
Hooked as bluetooth device in my vehicle, other end hears me fine.
On phone call using speaker phone, other end hears me fine.
On phone call WITHOUT speaker phone, other end cannot hear me at all.
Using a sound recording app to record voice, playback of the recording I can hear my voice faintly if I was YELLING during the recording.
Shazam/Soundhound apps do not work.
I am rooted on rasbeanjelly/trinity kernel. I have to say this issue started a few days ago when I have done no changes to the phone. Already running the rom/kernel for weeks.
I've tried flashing back to stock rom/kernel and the same problems persist.
Any ideas?

Just an update, I unrooted and reverted back to stock and the problem went away, so it was defnitely a software issue. Will be trying other roms/radios/kernels and see if the problem comes back.
I was on rasbeanjelly 4.2.2/trinity

akira112, did you get any success with your experiments?
Guys, is there any progress / comments regarding this issue?.. Microphone itself works fine when recording the voice with some app, but during the voice calls it is the mess...

My Nexus 4 is two months old and is being returned to Google due to the microphone constantly cutting me out on calls to business clients. I've tried every trick from sound apps to custom roms. No joy. I'm hoping my replacement doesn't have the same problem (although given the sheer number of postings on this issue, I suspect a Nexus 4 design flaw)...

Hello
Is there any solution to low microphone volume problem?
I have been using my N4 for a week and some people complain about my voice's volume. There was no such problem with my previous phone (Defy). There is no difference whether I use phone's mic or bluetooth headset.
My Nexus runs CM10.1 with Franco kernel.

Also keen for a solution
I just returned my first N4 due to the speakerphone cutting out after a minute or two, and getting stuck in non-speakerphone mode.
The replacement seems to not have this issue, which is nice.
But now people are telling me they can hardly hear me. It happens both with normal mode and speakerphone mode.
Ridiculous.
I will be calling Google tomorrow to see what they say, but I am not going to hold my breath for a decent response. Judging by the number of people reporting this issue online, it's not something Google has a solution for.
If anyone figures this out, I'd love to hear about it.

Have sent mine for repair because of this problem. People told they could not here me well.

I have the same issue, couldn't fix it but what I noted was that any mic gain adjustments I made only applied to the phone's mic not the headset mic. That means that there is something else that modifies the headset mic, but I do not know.
