hello all...
i'm looking for some help. a couple of days ago my VZ's GNex speaker stopped working. it occured on my way home. my son was watching a cartoon on YouTube and the audio was streaming through my cars head unit via BT. everything was fine. when i turned the car off...the audio didnt transfer to the speaker...as it usually does.
since then...no notification sounds...no ringtones...NOTHING!!!
my headphone jack works fine. my earpiece (for listening to calls) works fine. the phone is ok...except for the speaker.
i am on CM9 running Francos Kernel.
i pulled the battery and rebooted. nothing. i relouded an back up (one that i knew everything was fine)...NOTHING!! i played with every single setting i know...nothing!!
my question is. is it hardware or software? and how do i find out. if its software...then maybe i can fix it...but if its hardware...i think i am going to need a new phone.
any body else encounter this problem? any fixes??
thanks!
so a quick update:
i started all over...went back to 4.02 using the GNex ToolKit...NOTHING!!!
speaker is still not working!!!
so i guess i'm going to head into a VZ store today...
alright...so here is my final status.
i called VZ last night and explain the situation. they transferred me to Asurion, who basically didnt do anything for me. except try to get 100 bucks from me to get a replacement. so after 30mins of a heated conversation...they basically said...we cant do anything...so go talk to VZ.
so i called VZ...and they transferred to Tech Support. and after a 30 second conversation (with the best tech support guy EVER!!) he said...we'll be sending you a replacement phone. should be here tomorrow.
i know that doesnt fix the issue...but i guess its a manufacturer defect...
long story short...i'm getting a new phone tomorrow to fix my speaker issue...
Hi,
I first posted this help request on Nokia Support Discussions on August 13, but amazingly I received no reply to date (I can't insert the link since I have no privileges for that as a new user).
I am experimenting a very weird and annoying problem with my Lumia 900. Some weeks ago, the volume level during the phone call became suddenly very low and barely noticeable. I can hardly hear the other speaker both calling and receiving a phone call. Apparently this behaviour is restricted to the phone call feature in normal mode. If I press the loudspeaker button, for example, I can hear the conversation perfectly as usual. Same using my earpiece: I can hear and talk without any problem. Moreover, the audio output appears to be OK outside the phone call itself: when using apps, music, games or any other feature except the phone call, I can't spot anything abnormal in the volume level, everything appears to work properly.
I would like to point out that:
1) the volume level during the call is set to the max. level as usual (10/10)
2) the master volume of the device, as set though both right-hand buttons, is set as usual to the max. level (30/30).
3) I turned off and on the device, I removed and reinserted the SIM card many times since then, unfortunately the problem persists
4) I did not notice any other problem before this happened, nor the device suffered any "catastrophic" event (such as drop, water or similar).
Basically, I can only hear a speaker during a phone call either keeping the loudspeaker always on or using the earpiece. It's like my call volume were set to 1 or 2, while it is actually set to 10.
Can you help me determine whether this issue may be software or hardware related in first place? Unfortunately bringing it to the Nokia Customer Care is not the first option for me at the moment. I bought my device in Europe, but I am currently in South America. I may consider using the local Nokia Customer Care and paying a fee, but first I would like some clarifications from engineers or advanced users.
Finally, a guy on another forum suggested me a hard reset. I confess I never did that before, is there any step-by-step instruction for this? Or does it make sense to wait for the next software update through Zune (currently I have 8779.12201, a new update however has been already released and should be available for my language within days or weeks).
Thank you very much in advance for any useful information
You can wait for the update or try a hard reset. A reset will restore you phone to factory fresh, so you will lose everything currently stored on the phone; photos, apps, messages, settings, etc. So be sure to sync with Zune to backup photos and videos first, and sync with your Live ID mail account to sync contacts. Restoring email accounts, contacts, apps and media are all easy, but could take a few hours (depending on how many apps you have). If you prepare for the reset (as you can) it makes things easier.
If your other option is to send you phone out for service, that could take weeks. So while painful, rh hard reset is the "quick" fix. If your volume problem persists after the hard reset, then you know its hardware related (be sure to check before and after installing any apps to eliminate any possibilities). If so, and after telling Nokia Care that a hard reset didn't solve the problem, it might just get you a replacement. Quicker than sending it out for an inspection. Hope you get it worked out.

It makes no sense to wait. I assume you are still under your initial warranty, so do the hard reset...after, as jimski says, you save off any pics or music specific to the device. You will lose SMS and SMS history , and any game scores.
Use reinstalled to reinstall apps after the reset, to get or apps installed more quickly.
Hard reset is a harsh way to test this out. However, if you test the phone before reinstalling apps, you cut to the chase real quick. If this is a hardware issue, do NOT wait for a fix. Replace the device and be done with it.
Good luck
First of all, many thanks to you both for your kind reply. It is refreshing to finally have someone listening to you when you really need.
It appears that a hard reset should be the first step to do in any case. While I have no idea when the next update with Zune will be available for my language, I can try to solve the problem alone. Is there any tested step-by step procedure for flashing Lumia 900 or Lumia devices in general? If yes, would you please point me there with a link?
Both your replies convinced me that bringing the phone to the Nokia Customer Care here in South America is definitely not a good idea. Yes, I am still under my initial warranty, I bought my device end of June, the problem is that I bought it in Europe, so my warranty is not supposed to cover me here. If the issue is at hardware level, there is very little they can do here for me without to exburse a lot of money, not to talk about the waste of time. Should the hard reset not work, I guess I'll have to wait for my next travel to Europe or having someone bringing it there for me to have my device replaced.
Anyway, I will let you now about any progress.
Many thanks for your help.

I'll start by saying, the Hard Reset will not force you to re-flash your phone. It just resets it back to stock settings. This is in fact the easiest and best way to try to resolve problems with your phone. To do so, go into your settings menu. Go to About, and scroll down to 'reset your phone', tap that, and follow instructions. This will delete all your data and messages, so be sure you've backed up first.
If you Absolutely NEED to flash your phone back to OEM Stock, you can use my link here: http://forum.xda-developers.com/showthread.php?t=1605144
One other thing to check (and what I suspect to be the problem) is the speaker itself. It sounds to me like you either have a failing speaker, or something is in the speaker hole. Look closely at it and see if there is dirt/lint/chocolate/peanuts/earwax/etc packed in the speaker grill. It's pretty easy for this to happen. Try blowing it out with canned air and see if that helps. Otherwise, it's probable that the speaker is going out or the connection is failing.
Good Luck, and be sure you decide before your warranty is gone. Send it off ASAP if the above items don't help. PS: Flashing back to stock may void your warranty, so decide if you want to take that chance, rather than wait for repair to return it.
Thank you very much again for your time. And yes, I had found that link in this forum and was already duly reading it. I just did not post this because I still have no privileges to post links.

One last question. Would you please clarify whether Lumia 900 has one or more speakers? The speaker grill on the bottom of the device has apparently no noticeable dirt or other foreign material inside it, anyway I will try blow it with air, maybe it will help. One thing I can't explain to me is why everything appears to be OK with the volume level except during phone calls. As I mentioned in my first post, the audio output with music, apps, games etc. is normal. When I use the loudspeaker in phone calls, no problem. So the question: is there any other speaker in Lumia 900 which is used for phone calls, for example on the top of the device? I don't think so, but if yes, this would definitely point to a hardware problem of THAT speaker.
Anyway, I will let you know about any progress.
Kind regards

There are in fact two different speaker outlets. There's the one at the bottom which is speakerphone, games, apps, etc... Then there is the one at the top in that little slot. That's the one I suspect is either clogged, or going bad.
EDIT: Do you have a case installed that might be blocking that speaker?

Got it. That makes (unfortunately) perfect sense. Chances are then that the issue is actually at hardware level

Same issue with my lumia asian rom...
Sent from my GT-I9300 using xda app-developers app
Wow! I thought I was going crazy....'cause I've had the same issues for the past few months. When I got my Lumia 900, I was pleasantly surprised that my in-call volume actually DIDN'T need to be set to max (10/10), and I usually dialed it back to 8/10. Nice...but it began to get quiet so that even on 10/10 it was difficult to hear callers -- especially if I was standing outside. I thought it had to do with a ROM or firmware update, but so few people noted the same problem that I just assumed my phone was faulty.
<sigh>
Anyhow, I found this thread just 30 minutes ago, read through your story, and (for whatever reason) thought it thru more fully. I realized that since I keep my phone in my pocket, maybe the thin ear speaker grill (just above the screen) is full of lint?!? I grabbed a soft, dry toothbrush and took about 30 seconds to brush it out. I could actually see the debris clearing away. Made a test phone call and voila.........my earpiece volume is loud once again! Easy fix. Almost too easy
I hope this helps.
did you ever resolved the problem?
Hi guys love the forum finally joined !
So i recently bought ebay Lumia 900 they are going for cheap =) loving it!
In my case the speaker was working great actually the first week it was way too loud kept it under 7/10 all of a sudden now
i cant hear almost anything below 8/10 and when i go all the way to 10/10 it sounds muffled like a blown speaker already tried cleaning the grill
very carefully it had dust but that didn't help and also erased averything from the about settings
.
Anymore suggestions? Im in the latest update and obviously no warranty .
Thanks :cyclops:
Hi
Are there any updates on this problem,because I am also experiencing this and I think it happened after I did an update with Zune .
Thanks
Hard Reset to Nokia Lumia to address low volume during calls
How do you to a hard reset of the phone. I am ready to try that to solve the low volume problem. I literally took the phone out of the box on Thursday last week. I am getting very frustrated.
Thanks
Hello All,
First off, hardware: I9250, stock ROM build 4.3 Build JWR66Y, not rooted, but bootloader is unlocked (CWM might be on there, it's been a while).
I noticed a few weeks ago after upgrading to 4.3 that I can no longer make phone calls without resorting to Bluetooth or Speakerphone (speaker ok, people can't hear me on the other end. I tried calling another phone I have (old N1) and I have to literally yell into the little hole at the bottom to start hearing anything in the N1). I have seen this problem being discussed with other phones (mainly N4) but not much on the GN.
Tried using an app called SoundAbout to disable wired headset detection, no go.
Tried booting into SafeMode, no change. I thought maybe using Volume+ might be incompatible with the OS upgrade or something.
1) Is anyone else having this problems? Supposedly this was a problem on 4.2.2 which got fixed on 4.3 for N4 users....
2) Anything else I can try before trying to downgrade to see if it fixes the problem? Factory wipe is something that I want to avoid like the plague.
3) Is there a way to test the hardware? Before I try and buy a microphone assembly?
Thanks in advance!
Bump
I have the same issue. After a nasty drop and some rain, I had to replace the screen. Now it works wonderfully except the earpiece during calls emits a lot of static and I can barely hear the other end, and they can't hear me.
Strangely though, with a headset or while on speakerphone, both directions are perfectly clear. I'm betting someting in the motherboard (i.e. audip processing circuit) is fried, because I've already tried replacing the earpiece.
Anyways, hope you find your issue, and let us know. Otherwise you'll have to stick to speaker or grab a new phone.
Sprint GNEX
Yes, I can rule out physical damage from falls, as I am anal about keeping my phone pristine. I haven't dropped it, and its protected by a good case in case there was some unknown shock.
I find it hard to believe nobody has ever come across this problem, even if not on a GNex. I'm just biased against any product made from LG (huge history of poor build quality outside of asia), and I'm pretty adamant about having a Nexus phone, I'm going to have to wait until Nexus 6 and hope that it doesn't go to LG yet again since motorola is eneligible for Nexus award (go HTC! the N1 was awesome).
Im using d855 , from the beginning the call clarity is very poor, calls are having distortion like broken voices
while talking with the phone ear piece. The other end ie the person receiving call is having no issues at all.
Headphone and loudspeaker clarity is better.
Is it a faulty ear piece or a some software problem.
Is there any one else facing the same problem.
Please help.
Maybe faulty, have you tried rebooting and seeing if that helps?
I have to say my G3 is much better than my previous note 3 or Htc one for call clarity

Great to hear that you getting good clarity on G3 than other devices.
Tried rebooting and resetting the device but no luck.
My intention is to make sure whether its a software bug or hard ware fault before handing over to the
service center.

Hi @mpt123
I have the same problem here:
http://forum.xda-developers.com/lg-g3/general/poor-call-quality-distortion-noise-t2808530
But, I can't consistently reproduce it - last evening it was consistently terrible, this morning it is consistently fine. I haven't rebooted in-between so I can't work out what is going on.
One thing is - I do frequently connect and disconnect from Bluetooth headset in my car - and I wonder whether this has any influence. Do you use a BT headset?
Also, do you find it is ALWAYS bad, or is it inconsistent like mine?

Hi, this problem is consistent for me all the time.
I'm using it with my headset, speaker mode and bluetooth , all of these worked well without any problem.
I have given this to LG service center and they confirmed it is due to the faulty earpiece.
They asked me to wait for 3 days to do the repairing . I took it back given to the showroom where i purchased
it, the manager promised me tomorrow they will get it replaced with a new one as my demand.
Also for your information in my case i did reset my mob, flashed it with the European firmware to make sure that the
problem is with hardware.
Hope this information will be useful for you at some time.

Yes I had the same problem with my earpiece. I went to CPW and got it exchanged, which was a bit of a hassle because I had to set the phone up again. Although I do have to say the LG Backup software is actually rather good. Backed up my homescreen layout and settings so not too bad.
However I now have a brand new phone and it has exactly the same issues with crackling and vibration. Almost like the speaker is too loud for itself but it really is not that loud or clear.
Do you think I should try to get another replacement?

I'm interested to know what network you are on? And does the crackling always happen, or is it only if you're in bad coverage area? Or some other cause/factor?
Tonight my phone behaves fine, but I'm worried there is some problem.

I am with Vodafone. I had the same thought just this afternoon and I think maybe it might be a signal problem. It seems to be worse when I am at home where I have full 4G coverage. I am going to turn off 4G tomorrow and do some testing just using 3G and see the difference.
Will keep you posted!

Hi I made a post on the other thread as I have the same problem. I'm also on Vodafone. I'm only in a 3g area not 4g but as I'm using a Three network handset I have no option to just switch to GSM.
I have however tried Skype through wifi and data and the earpiece is crystal clear so I agree this appears to be either software or network related.
Will keep you posted!

I called CPW today and they were great. Took it to my local outlet and they swapped it out for a new handset without any hassle at all. They have a 28 day exchange policy which they totally seem to honour.
Not had a lot of chance to test the replacement, but the calls I have made have been crystal clear with no noise, crackling, or distortion. Will update again after a few days.
To re-cap: I had crackling and distortion on the majority of calls but only when using the earpiece - sometime it was worse than other times. It was always fine when in speaker mode or using bluetooth. New handset doesn't seem to have this problem.

the weird thing is that when using skype its always crystal clear. its just GSM calls, so surely can't be hardware issue can it.

I had my phone replacement yesterday with a new one ,the earpiece is very clear though is not that that loud but iam very happy
with it bcz the earpiece on the previous one was so noisy with crackling sounds and i had to use my headphones all the time.
I have seen many reviews with excellent results on call clarity and all , so its shouldnt be a common problem with the phone.
Try to switch the network and compare the clarity , if the results are same then go for replacement.
I have exactly the same problem... All the way here in HK!
There may be a Faulty production batch. Unfortunately the retailers in HK only do 10 Days Swaps so will have to hit the LG Service Center... hopefully it is covered by the Warranty!

LG G3 Earpiece Noise Problem
Unfortunately before buying this handset I have not checked about the problems that already exists. I also got G3 with same earpiece digital noise/ buzzing noise problem which usually comes when it first try to connect after dialing the number and then it comes during the call also.
I got 1 phone replaced in Bangalore Sangeetha within 2 days of purchase and the 2nd phone also have the same problem. It seems some batch problem. This is my first LG phone and hopefully the last one.
I have given 2nd phone back to Sangeetha although they suggested me to go to LG center. I don't know where this phone will take me, preparing for a customer court :crying:
I've got this problem with my D850 in the UK on Three, I hear a crack or pop a few times during a call. Has anyone tried turning off noise suppression and voice enhancement in call settings to see if that makes any difference?
I turned off voice enhancement and call quality has improved so far.
Hello,
from time to time, persons i'm calling tell me, that they hear really bad interence sounds. They sound like when you bring your phone near to loudspeakers. I can't hear this problems, the call is absolut clear on my side.
When I'm in the car and the phone changes to GSM/Edge, i can hear it over the car-speakers. So i think the problem depends on the GSM-Network.
Is there someone with the same problems? Did someone solved it? Does HTC know this issues?
Thanks for response,
Bond
Some here...
Same with my phone, really loud inteferences on the other side, sometimes louder than my voice. Depends also, how the phone is located in the room. While walking, the noise appears / disappears. Does this have something to do with the three build-in mics to improve the voice quality?
Android: 5.1
Firmware: 2.10.206.2
Im still dealing with this problem. And i couldn't find the absolutly right solution for it.
I bought my phone at amazon.de so i contacted them. They sent it to regenersis to repair it. Regenersis changed the following parts:
36H01982-00M - zam. 36H01936-04M; Speaker, AAC ELECTRONICS, DMSP0815D-J-01-FB
72H09061-00M - EMI Gasket, LCM FPC gasket combine absorber
74H02837-00M - zam. 74H02837-01M, Cover Pre-Assy, Plastic, CIR, Generic Color, Generic Process
The Process needed about one week incl. transfer with DHL and UPS. But after all for nothing. The problem was still there. During this week a read that sometimes this problem is produced from the SIMcard. To check this out you should "cross-change" your simcard with another one maybe from your friend. I didn't done this i just called my provider and he sent me a new card.
The problem is still there in my phone.
Another problem is, i would have to pay for a new nanoSIM. So my old SIM and the new free change SIM are a microSIM i had to cut.
I've contacted Amazon again, i will get a new device on monday. If the problem is still there on the new device i bite the bullet and pay for a native nanoSIM. And after that i have no plan.
If you can read german language... They deal with the same problem on the One M9. I've also wrote down my story there http://www.android-hilfe.de/thema/stoergeraeusche-beim-telefonieren.697510/page-2
Good Luck
After reading the thread on android-hilfe I would say chances are high that cutting your microSIM is the problem. If I were you I would try to use a "real" nanoSIM. I never experienced such problems and I'm using a "real" nanoSIM since I bought the M9.
Sorry, but using the wrong SIM causing interferences is completely nonsense. Looks more like HTC has some shielding problems with the M9.
@blackswan, i would aggree with you. There are no technical connections i could imagine. But i've read about from different sides, not just from people in forums who are oracleing about.
From my part i've got the new device from amazon. It seems the problem has been solved. The "old" One M9 was from Taiwan, the new one is from Hsinchu. Unfortunately the display of the new one is with a hint of green. I hope i can get used to it during the time. Everything else works well.
After two weeks of absence, I received my HTC back from service. What should I say? They change the speaker of my phone!!! Needless to say that the interferences still remain.
Sent again with 4 picture to explain the problem. Hopefully someone there will understand. If this try fails again, I will reverse the purchase!
I have had the same problem intermittently when connected to bluetooth in the car. Really bad feedback on the other end that i cant hear at all.
My carrier is o2uk and it happens on any band.
I wish I stole my HTC M9.
