hi there, I have been experiencing this issue with my Galaxy note 9 (SM-N960F/DS). suddenly yesterday day I noticed that the volume the bottom speaker of my phone has dropped drastically, even bellow the volume level of the earpiece speaker, I tried wiping cache and what other stuff I could think of to try to fix the issue but nothing worked.
Finally as my last resort to make sure if maybe it is a software issue and not a hardware one, I factory reseted it, it started to work just fine after that!
But it didn't last for very long, next day, after when I woke up, I noticed the volume has been dropped again. Now I am sure as everyone would understand, resetting my phone everyday is not an option for me
I tried asking Samsung help center but they say I need to bring it in to the nearest service center, which is not an option for me, and who are kidding they don't help, they suck.
SOME INFORMATION regarding my phone
●Note 9 SM-N960F/DS
●Updated to One UI 2.1 a week ago
●I never have had any problem before
●Speaker started to work factory reset have proved that it's a software problem
●Samsung care sucks
If anyone is having the same problem please do post, and anyone who has any idea what's going on please do post too, your help can literally save my life.
Thanks everyone
Hi there
I had similar issue with the ear piece..
Tried all updates etc no avale
Got a dry toothbrush and cleaned over the grills
Worked a treat
Maybe something ie dust etc is distorting the sound
Worth a shot

I think that maybe the case too. Or you could take a handheld vacuum cleaner to it with the crevious attachment to suck out any dust or debrie that maybe stuck in the speaker grill

Hi Eddie, I would have agreed with you but the thing is that doing a factory reset resolved the problem for me once, then it eventually appeared again, so this indicates that it is a software issue! No?

But then how did the factory reset fix the problem for me once? I am sure it has something to do with software. Can you think of anything that I should try to fix it supposing it's a software issue (other than a factory reset of course) thanks.
Hmm seeing that you have corrected the issue in the past by doing the factory reset it is possibly a software issue..
Possibly try a reflash using odin?
It won't break your warranty unless you have rooted ij the past..
If that fails take a trip to samsung get it repaired under warranty
All.the best eddie
hi, go to service menu by dialing *#0#*, and test speaker there. this will confirm whether it is hardware or software.

Hey Eddie thanks for the odin suggestion, I tried it and finally realized that I was just being too stubborn to admit that my phone has a hardware issue. Turns out the audio never got better after a reset, it just felt a bit different as I wanted to be it that way.
Anyways time to admit the hard truth it is a hardware issue and I think won't get it repaired, both speakers now get as loud as an S8 which by any means is not a the best speaker out there, but it gets the job done, thanks for time, Abdul Wahab.

I had the very same problem. After the update. Same phone Other than the phone heating up and taking really long to charge, the speaker output dropped then got flakey. And finally stopped working. All this happened after the update.
Did a reset. Even took it to the service center and let them re-load the s/w.
Nothing helped. In the end both speakers, both mics, and ear jack will stop working.
I traced the problem down to one of two ICs one is the Max98512 or the 9896B.
If your out of warranty they will want to charge you 28,000 + for a new motherboard.
They looked really hard for physical damage and water damage. But my phone is immaculate.
From the showroom got a world-class case and screen protector.
Not a scratch they could find. I don't even take my phone off my desk. Kids actually nobody is allowed to even touch it.
At first I thought it was something I did. But as you research update problems you will see many issues from failing audio to failing displays.
The local small-time repair shop service guys will say we can fix it. But they pull a con. They just reball the audio IC and hit it up with heat. There is a chance that it will start working but the repair will not last.
Last option is to put the chips on Ali express and replace them yourself. Which is what I will do if Samsung Shafts me.
I have e-mailed the Service head of Samsung to resolve the problem.
My logic is that a flag ship should last 2 years at least.
If they shaft me on this Samsung have lost a loyal customer from Note 4 days.
You could get lucky doing things like cleaning the ear phones, the cache etc.

So the phone (XT860 Bell) has problems when I unlock it the screen stays black. The phone works though cause when someone calls I can still pick up as I know somewhat where the green button is. But for the rest I can't do anything.
The only way to get the phone back is to remove the battery and restart the phone. Then it works again.
Anyone else had this problem?
have you tried hard resetting it?
No will do so. But before doing that I thought maybe there is some simple solution.
After the update to 2.3.6 things went all a bit wrong I think.
If you got this after the update, I am quite confident data wipe will solve your problem. You can try wiping cache only first - this way you won't lose your configuration and might solve the problem. The update supposedly wipes cache, but maybe that didn't work properly while you were updating. Enter stock recovery and give it a try.
Hey thanks for the help. But just did a reset. Not sure what went wrong when I did the update. Did wipe. Annnnyways. Right now it's stable. Let's see if it stays like this.
Ok sadly the reset didn't fix it. It took a whole day to go black again but still happened.
Any other solutions? I am scared that it's a hardware failure...but let's hope not cause I am in Holland.
I have the droid 3 and the same exact thing is happening to me. Sorry to tell you this but it has to deal wit the connector between the keyboard and screen. I've taken mine to get checked by a "phone doctor" and they told me that. I will tell you this now ,since it is still in the early stages, it's going to get worse to the point that it will stay black. Get it fixed by a techy or get a replacement soon. Mine reached it's point today and I am going to need to get it fixed. Hope it helps.

Doesn't sound good man :-(......
Though it happened a lot the passed days since the reset ( knock on wood) only once. Do wonder why it happens less now.
Yea you can reset all you want it's going to go blank. I had to right the dial pad numbers with marker on the screen just to make calls. I say get it fixed or replaced soon
I've got the same issue here. I know the thread is old, but I'm from the Netherlands (just like eezdva) and would like to know how to repair this.

If you can't take it back and want to try to fix it yourself you need to search for a droid 3 flex cable. The one you want has the front facing camera, front sensors and earpiece speaker on it. Then head on over to ifixit for a teardown guide (sorry no repair manual yet, I plan on working on one).
I have to add that taking this phone apart to replace this part is no small feat, and it would probably be better finding a phone doctor to do it for you, or just getting a new phone.
When you buy the part, request an OEM part, I have been sent cables where the front facing camera displays sideways, or doesn't work at all. Most also don't come with the front button deflector, and that has to be transferred from the old cable.
Hope this helps
Ok . Well I don't really know what the problem is. But it went away. Actually it started I think after applying the update . I got myself another external sdcard . At a certain moment I decided to remove it and things cooled down. It now actually never happens anymore.
Well I gues you're lucky!
My screen sometimes starts all scrambled and the phone doesn't power on. Sliding the screen a couple of time sometimes helpes, but most of the time I don't really know howto get the phone working again. I think it's more stable when I leave the phone 'slided out' (don't know the right word now).
And I searched Motorolas website and found 2 reparing companies in the Netherlands. They both are authorized by Motorola, as of such I think this repair will be in warranty.
I do have to send it for repair. I don't want to take it apart because of what bitz_dv said. I'll let you know!
No Fix
When I was gone on a short holiday my college got a call from the 'authorized' motorola repair center. They can't fix my phone. I need to pay 11 euro to get it back and that's it. I tried calling them but there was no answer.
I sended my phone in on 22 may 2012 and now they decided they can't repair it. I spoke to Ted from Negri Electronics who told me to get in touch with Motorola as my warranty is still valid.
I'm a little confused, where should I go if an official repair center can't fix my phone but do tell me the repair is within warranty..
What can I do? Besides ordering the parts and take the phone apart myself..
I started my search for the flex cable... I did repair a N97 once, within the warranty period and later on sended it in and they repaired it under warranty....
Is this the cable I'm searching for:
http://www.globaldirectparts.com/Motorola-Droid-3-XT862-Motherboard-Flex-Ribbon-p/mot1040660.htm
I am from Netherlands, and have the same problem with the screen, looks like many users from Netherlands do.. coincidence?
When i jst slide out the keyboard , a little bit is enough, and the screen goes black ( black screen of death ) it doesnt power on with power button.
I looked for a flex cable at ebay, and it surprised me , that cable is also doing the front camera, and speaker... My front camera wasnt working too, and speaker made strange sounds many times, so it could be that cable, but not sure.
Check my thread, i have also uploaded a video to make it more clear

Hi there.
I have the s5mini now three days.
The problem is that my friends understand me very very quietly. In the German thread are many Users who have the same problem.
How is that with you?
Is it not possible to adjust something in the service menu ??
Sorry for my bad English...

you need to clean mic hole by needle or toothpick and problem will be solved
I also had the same problem as in the original post so I came here for complaining.
But after trying the needle suggestion above (cheers to the usasha!!) the problem got fixed!!!!
I was about to return it to be serviced, but now I'm so happy with my S5 mini
I used a thin needle and inserted it carefully for 3-4 millimeters, some lint came out.
We have exactly the same problem!
Bought phone and it went to service 3 times in a row. They've replaced everything from microphone to motherboard, even "cleared the mic hole". So, as you can see, we've replaced everything and it didn't get better.
Service even replied that the phone is working as it should. We bought it at the end of august, used it 4 days,.. other days, it was on service.
@greglord: is your last post some kind of a game with finding differences?
Usually this is with two pictures, so I find it very unique using posts instead.
Back to thread topic - I also used needle and now people hear me more clearly than before so thank you @usasha !!
I've installed sound meter from PLAY on 2 android phones my old Desire S and my new g800f. ive noticed that there is a 30dB difference the old one receiving better sound then the 1 day old g800f. sad!

Those who took this advice can say good bye to the water resistant certificate.
All water resistant phones have bad microphone performance!
That's not entirely true, my friends immediately reported that I sounded loud and clear without asking, when I switched back from my G800F to my Xperia ZR, even without them knowing I switched phones. Maybe the sound isn't as good as a non-water resistant phone but it sure can be a lot better than my G800F.
I just got my phone back from the Samsung repair shop, after almost 2 weeks (!). But I doubt they have done anything to fix it because the screen was as smudged as when I brought it there. IIRC well the screen has to be taken out to replace anything inside the phone, or am I wrong?
How to solve this problem without loosing warranty?
I have SM-G800F with stock Android 4.4.2 updated from Samsung to the latest update I can get. Not rooted.
I have mic problem since I've bought this phone two weeks ago. People talking to me say that my voice is muffled as if I hold the phone too far from my mouth. This happens only using phone mic - if I switch to speakerphone or earphone during the call, everyone can hear me great. So, the problem is with the phone mic as if the mic level is too low .
I've searched all over the web and have realized that this is very common problem with S5 or S5 mini. As a solution, people suggest "cleaning" the mic hole which puncture the waterproof membrane of the phone and you loose warranty.
Another approach that could make progress is by editing default_gain.conf file at root /system/etc/ (more at http://forum.xda-developers.com/showthread.php?t=2777535) but for that to work you need to have root which also void warranty - correct?
Suggestions like taking out the battery or wiping the cache partition didn't make any improvement for me.
The only hope for me is hint the I've found the post (http://forum.xda-developers.com/showpost.php?p=55192014&postcount=2) on this forums suggesting raising mic level gain setting in phone service menu could solve the problem but there is no explanation how to do it. I've tried to enter the service menu using *#*#0011#*#* and then Menu -> Back -> Menu -> Input Key -> Q -> Menu -> Input Key -> 0000 but service menu doesn't appear like it should.
Any suggestions either on how to enter the service menu or some other way of solving the issue?
I had this phone like 2 days. I unsealed it. It's a nice phone but I recommend don't waste your time with it. Get rid of it you still can
Samsung S5 mini G800 microphone problem solved
Today I had a problem with the G800, the microphone doesn't work when talking about a call, but it works when recording a dictaphone.
I replaced the charging flex, but I didn't solve the problem, the microphone in the call didn't work.
Then I replaced the top microphone on the motherboard, which is used for speakerphone conversations,
and I heated audio IC WM1811GE it with hot air at 320 degrees Celsius for 20 seconds and that's it. Problem solved.
Now my S mini works perfectly, now the microphone works in a call or conversation. :good::good:
Audio IC Samsung G800
position WM1811GE Samsung G800 mainboard
Mic in mainboard (mic for speaker call)
So, fist time post.
Anyway, a friend of mine gave me his Flex the other day. He was upset because he couldn't get the sound/audio to work and no one could hear him on his end, showing his mic wasn't working (first time this has happened). After tinkering around for a bit (cleaning over and over), trying everything I could, even downgrading it from 4.4.2 to 4.2.2 to see if it was a software problem. Still nothing. Yet, when a headset or just normal headphones are plugged in everything works fine.
So, after all of that we took it in and they said it wasn't a hardware problem, but they couldn't find a solution and they couldn't replace the handset with his warranty already expired. So, I was hoping there was someone here who could help me. I was thinking maybe if there was a software problem I didn't catch if installing a custom rom on it would help. I was hoping to hopefully get some insight before going to that.
Also, sorry if this is in the wrong section, still new here.
There are no "custom" per say ROMs besides the cm11 one Playfulgod and I have posted in the dev section. If you're on 4.2.2 download Playfulgod's cm11. But it doesn't stay booted and there is no data. Download mine ,which is only Playfulgod's cm that I've modified to boot with 4.4, and the is no sound but it has data and stable boot. I don't suggest either one as your fix though. If you flash the stock 4.2.2 or the stock 4.4.2 software to it and there still is no sound except through the headphone jack then I can't imagine it not being a hardware issue. I mean it pretty much has to be a hardware issue.
And besides the kats at these stores selling you the phones or answering your questions, stereotypically no smarter about the devices than any other 20 year old that has googled and memorized the specs of the phones. They know specs and sales pitches. Other wise they have to revert to the computer and go through a series of elimination questions to diagnose your issue. Ive even had to show one rep how to use lg PC suite to flash his g2 back to stock. And that's the standard issue software that we all have.
My best guess on your issue is the device could have been dropped or damaged in some way that has loosened or broken a connection or part inside rendering the speaker useless. But that's my opinion.
Well I don't think it's been dropped. At least he said he didn't drop it. After pulling it apart I made sure everything was in the right place and nothing was shorted out or disconnected. So I'll probably send it into a repair shop to see if they can do anything with it. Though a headset would probably just be the better way to go, it's just an inconvenience.

Absolutely. I would hate to have to through in my ear buds every time I had to answer a call
Well after installing Master Volume Control, I have been able to test that the speaker does in fact work. But no sounds of any kind aside from voice call, work, the normal beep you get when using the volume rockers. This is starting to drive me crazy.
might have solution
Just received my refurbished flex phone, realized no sound from speaker. Popped the back off a couple times, suddenly I hear sound! The cable over the battery when lifted and remove the crease caused by shape of battery removed, speaker now works! I hope this helps you. Best of luck.

My phone decided to not switch on any longer. The only sign of life is the notification led blinking red when is in charge, no way to access it with any program if I attach it to the PC with a USB cable.
I should send it to the Sony repairing center (still under warranty) but the phone is rooted; given its situation do they discover it ?
I had that exact problem. Turned out that the battery suddenly died after about a year.
In my experience they never care what stuff is currently on the phone. Instead they'll just flash it with the latest stock rom after fixing the hardware.
Thanks a lot for sharing your experience. I really hope will be the same in my case as well. I'll post here what will happen.
PS I'm wondering about the batteries' quality: my daughter with a z1c had your same problem (a little more than one year life), you, may be myself... I know the sample is not significant but...
Same thing happened with mine & i was on a custom rom with unlocked bootloader...they probably had no way to get into the phone just like i couldn't so they probably couldn't tell it was modified...it was just a brick at that point...i noticed certain batches were affected by this sudden death and after pulling my tag out i noticed my phone was part of that batch that was poorly assembled in china...so brand new phone for me!

I have the impression they dont even check the software, they just flash a new fw and thats it. Or they dont care.

Thanks for the suggestion but I tried any possible way to resurrect my phone, including what you're saying, without any result. I hope to confirm soon what all the contributors to this thread are saying...
Just received the device from assistance; everything went well: the motherboard was replaced.
The only drawback is that the lost the tiny grill that cover the mic at the bottom of the phone !!!!!
Hello,
Both the earpiece and the other speaker suddenly stopped working on my nexus 6. I am suspecting it is a hardware issue since I performed a hard reset but the issue still persists. The odd thing is that both the earpiece and the speaker are affected at the same time. Are they connected to each other?
Is there any way I can make sure that this is indeed a hardware issue before cracking open the phone?
Thanks

Another question, some times i turn on my display an for 3 sec i had more than max brightness, like a sun, no auto adjust always 20%, may the old nexus now die hard, hope not
Before I opened the phone, I'd boot to safe mode and see if things work. If they do, reboot and see if the problem comes back. Booting into safe mode disables all unnecessary apps, clears caches and resets settings to default. Sometimes that resolves your problem and on reboot things are working again.

So I guess it sounds like hardware. You might take s close look and see if there is damage/dirt in the jack making the device think the headphones are connected. The pin is easily bent and wears so it's probably just that. ifixit has a repair guide.
Alternatively, you might consider Bluetooth headphones [emoji4]

Thanks. I don't think it's the jack issue because I installed an app that shows a headphone icon in the status bar when a headphone is plugged in and it doesn't show it when nothing is connected.
Do you know why both speakers ceased functioning at the same time AND if there is a way for me to direct audio to only one of them, either the earpiece or the speaker, to see if one or both
are dead?
wow. I reverted back to an earlier build from Feb and now it's working. Very interesting.

First, sorry to hear about your problem. But, I am actually happy to see this up at xda. Tell you why. I purchased a uesd nexus 6 from a seller on ebay. Description was everythings works. Pics showed it was in excellent condition.
Problem was when it arrived. I discovered the top speaker was trash. Total robot like voice. Of course seller denied any knowledge of it. My option was to return it to him. But judging from the way he spoke to me. I could tell it was going to be a fight. There is no way he did not know about this. I wound up eating the phone and am currently awaiting a new top speaker. So, please dont forget to ask about speakers if buying used. My concern was body and screen. I never thought to ask about speakers and I never thought there would be crooks like him. Wrong...

It is interesting. Is it possible you had a mismatch between kernel and security updates? "Newer" kernel on "older" ROM? Or vice versa. The difference doesn't have to be more than one has a security update that the other didn't.

Know this is an older thread, but just figured I'd post what I found regarding a similar issue I had. My phone basically took a 3 second dunk in the sink. Everything seemed fine the first hour or two, then the speakers stopped working. However, it seems like the speakers failing is some kind of water damage failsafe or something. The solution is just to turn your phone off and on around 5 times (I can't remember the exact number, but once or twice won't cut it), and you will have the speakers return to normal. Not sure if the OP had the same issue, but just an idea in case something similar happens to others.
Bumping an old thread but I had this same issue and had to flash back to previous builds. I stopped updating my phone around Jan/Feb. Tried to update to the Aug 7.1.1 build and the same thing happened again. I didn't try the turn on and off 5+ times, I'm just once again restoring my Jan/Feb build.
Can anyone else confirm this "fix" or has this same problem?
I'd boot to safe mode first. If it works then, it has something to do with an app, your app restore process or something like that.
