Acer Liquid - phone speaker problem

I tried to call for the 1st time today.
When I call to someone, or vice versa, other party can hear me, while I hear nothing at all via ordinary phone speaker (on the front side). Volume changes does nothing.
If I tap "Speaker" - I can hear other party via another speaker (on the rear side of the device).
If I plug the headset in - agian, it works normally as supposed.
Is my phone speaker broken or do I miss something? I played with every settings I could find, but nothing helps...
Did anyone have the same problem?
Acer Liquid, 1.6 orginal rom. I didn't have a chance to reinstall rom yet, so it should be just fine. I did install a few apps from Market.

I had exactly the same problem.
I was using ROM LCR 1.6.
I have just reflashed my phone and still the same problem, I think it is broken.
I've bought my Acer Liquid two months ago!

sounds like a hardware problem with the phone speakers. Normal calls should be heard through the speakers above the screen. speakerphone/ringtones/media sounds go through back speakers.

Had the same issue- returned it for another one.
@

I had a same problem. My phone speaker does not work.

Hi guys,
Just to let you know. I contacted Acer and they immediately told me that I need to send the phone to them for repair. (maybe it's a know issue).
I did that. 3 weeks after got the phone back. It works fine now.
On the paper I got with the phone they said that the part changed is "reciever"
So for those who have the problem - send your phone back.

I encountered this problem today....
I thought it was a hardware problem...
A Full Wipe cleared the issue..
You should try a full wipe before conclude that its a hardware issue...

I had this problem as well on my Acer Liquid E. Mine was a hardware issue, as when i would grip it tightly or press on the earpiece I would get intermittent sound but there was static. I did 4 wipes and nothing solved it.

Sry for that! Just don't grip it tight
We all know its a very fragile device...
Acer should have engraved "HANDLE WITH CARE" on both side of the device.

I have fixed the hear speaker
Hi all! I had this problem with my Acer Liquid, I had no warranty so I tried to solve the problem and succeeded. It's not software or configuration, it's a broker hear speaker!
Symptom: You can hear the person on the other end with Loud Speaker, Bluetooth Headset and Hear Phones but you can't hear via the Hear Speaker.
Problem: Broken Hear Speaker.
His problem is reported all over the Internet but with no solution beside sending to Acer.
I risked and fixed it myself by dissembling my Liquid and find a compatible hear speaker.
Big Problem: No spares parts anywhere for this device.
Solution: Blind search for a spare hear speaker by looking at pictures and compare with broken one.
Big Solution: This speaker is also used on a series of iPaq (HP) PDA's and i found a website that sells them quite cheap.
I found two compatible models of speaker and i leave the links here.
I bought these two:
www*repairhppda*com/front-speaker-for-hp-ipaq-voice-messenger-p-1822.html
www*repairhppda*com/internal-speaker-for-ipaq-910-912-914-910c-912c-914c-p-1235.html
!! I can't post links so remove the * and put dots on the links.
I've only used one so can't say which i used because they are very similar, but one of them works for sure the other i can't guaranty but I'm almost sure it also works.
(it seems like it could fit but don't know and can't confirm... did not buy this one)
I disassembled my Acer Liquid, replaced the hear speaker, and Bang! It' Works!
Notes: Be careful when disassembling your liquid you could easily break something, take steps slowly and carefully.
If you need any hint, speak here, i'll try to answer as soon as possible.
Cheers!

I am having another problem. The people from the other side hardly hear what I say, they say my phone is too noisy, especially at the beginning of the call. The quality is ok for me, I can hear everything very clearly.
I don't know if it is a hardware problem or just (hopefully) a problem with the baseband or something like that.

I have the same problem.
I tried to flash a different baseband and apparently it started working ok but after a while the noise was back again.
The strange thing is that the noise seems to pop up only when I call from certain places and not from others.

Yes, it's a very annoying problem. Since the other party cannot hear me clearly, now I have to go back to my HTC Touch HD until I found a solution for this.
I bought this Acer Liquid as a 2nd hand one without invoice, so there is no way to return to Acer for a repair service.

Yesterday I received a call and I couln't ear anything, then I tried to callback (thinking it was a network problem) and I still couldn't ear anything. I used the loudspeaker and it was working, also plugged my headphones and I could ear the other party.
I then called Acer complaining, they told me the phone needed to be repaired (the quickness on the response made me think this is somehow usual), that I should put it in a box with the RMA code written on it and that they would send me DHL to pick it up. Today DHL picked the phone, so far everything as been dealt really fast and I can't anyhow complain on Acer support, lets just see how long it will take till I get my phone back.

in-call static/interference/resonance/noise problem

Hi guys,
i think there's a problem in my i9000;
whenever i make a call, i can hear low static interference in the background.
i searched both on xda and elsewhere, and although some other people complained of this problem, no one was able to determine the cause or provide a solution.
i tried different roms, froyo and gingerbread samsung roms, in addition to cm7, with different kernels and modems, heck i even changed my csc(just for sake of changing everything to make sure.. all for nothing. the problem persists.
Does anyone know what might cause such problem and how it may be solved?

i have exactly the same problem. Like you; i tried every combination which i can. I think main cause of the problem is hardware related. But my opinion is ,it can be fixed with device drivers. I looked at service manual. In the speaker part of the service manual,you can see there are two inductors and one capacitor before the speaker module. You can see the full circuit in Service Manual Page 42.
h**p://img191.imageshack.us/img191/2383/speakerj.jpg
I think these inductors(L209,L210) are interferencing with the GSM frequencies and making that static sounds on the background.
We need someone who is an expert on linux and device drivers. Maybe he can show us to find a way to break this circuit(temporarily turn off B1 and A2 pins) in a call so it will not make that sounds.
In the other hand we may have defect phones. May be the only way is to change some parts.
sorry for my bad english.

I think there's something wrong with the speaker itself.
I'm taking the phone to samsung's maintenance to see what they have to say about it.
I'll report back once i get to the bottom of this..

Same here, but it's not constant, just happens enough to be noticable, bloody annoying, and only started (or I only noticed it) a couple of days after JVP. Will be interesting to see what you find out...

One possibility, do you have your phone in a magnetic flip case? Worth checking

No magnetic flip case, just a hybrid (plastic back+sillicon frame) cover.
I even took it off for a while to see if it was causing the problem, but no.

I went to samsung service center and they said it will cost about 200$ because the ear piece comes with the touchscreen..
Meaning i would have to pay for a new touchscreen even though i only need the ear piece.. How about that for service.
I checked ebay and found the whole ear piece+speakerphone+headphone jack in one bundle for 15$
so guess what my next step will be??
Buy and install the ebay part, sell my i9000(never liked tw anyway+cm seems a long way from home).. Had enough samsung for one lifetime

are you sure about the sound is coming from the earpiece ? i am asking because few weeks ago i was also assuming that the interference sound is coming from the earpiece . But i realized that it is coming from the rear speaker. Can you test it ?. In a call ,turn back the phone and put speaker hole to your ear. The interference sound is so loud that you can hear it from the earpiece hole.

This is the question which i am also looking for answers
Everyday i am searching for answers. Only a very few people experiencing this problem.
I think this problem is coming from the inductors in the speaker circuit part. You can look my first post .

i have this problem too, i live in Romania, i tough my phone was broken, but a friend's phone also does that.
i notice it when making call while 3G data was running in the background. If 3g is off = no noise.
Also i have noticed, the way you hold the phone affects it. try holding it with 3 fingers to your head the covering the mic hole with the other. you should hear some interference right there. so it's probably: speaker+ extra sensitive mic + some antenna things
Also my friend had the phone for some months now and never noticed it i searched the web and we're not alone, i found this discussion on a couple of other forums, still nothing to do, or nobody reported back after they whet to the warranty service. i would go, but i don't have any warranty on mine.

I'm also from Romania and I noticed this annoying issue today. All my other friend with Galaxy S also have this problem, so I guess it's a normal thing.
The only solution, I guess, is to use 3G networks, at the risk of draining a bit more battery.

so bottom line is that on mine, i hear noise/buzzing/interference when i use 3g networks both on the speaker on the back and the earpiece (it's louder if i use 3g data while i'm making a call) - the issues goes away completely in gms(2 g) mode
and it depend on how i'm holding it - it's louder if i grip the phone in my hand (probably the wireless signal is lower and the phone increases the power needed to communicate to the network thus experiencing buzzing sound from the speakers like radios did back with the first cell phones before receiving a call)
so i guess i'm not the only one, right?

This issue is normal I think. No big deal. If the noise however gets so loud that it interferes with your call, get it changed. But the new ones you get might have the noises too. So what is important here is to keep the noise to the minimum.
With / Without the noise is totally an unknown cause now. At least have it settled to the least noisy.
*This is happening to everyone who is getting the phone since November 2010

I confirm this issue with more models.
Hi guys!
Bought myself my GT-S5570 (Galaxy Mini) a couple of months ago. This is my first Android experience. At first I was pleased, but then I noticed this static noise whilst in call. It's like, suddenly I can have ill-isch, distorted, "noise spikes" sort of things. Left my phone in for service under warranty. When I had it back, it was still messy. Bought myself a GT-5660 (Galaxy Gio) a week ago, thinking that this one would clear the issue. It's still there, though. I'm wondering if this is something that affects the whole Galaxy series, even the tougher models like S/S2.
Related threads, by me:
android.net/forum/samsung-galaxy-mini/60951-sudden-volume-spike-during-call.html
androidforums.com/samsung-galaxy-s/307523-samsung-galaxy-s-gt-i9000-static-ear.html

yesterday my cousin bought i9000 too. First of all i looked for the noise. It is interesting that that phone is nearly noise free. If i gave 10 point noise to my i9000 than that phone will be 2 points. You can hardly hear the noise. After that i get her SIM card and test my phone with that sim card.Noise is still there.I make that phone software same with my phone. That phone still has no noise.
I think the problem is in phone parts. Maybe a defected series of speakers used in our phones. I will buy a new speaker module on internet. I hope that fix my problem.

For me it depends more of the network I use than the phone. It happens sometime with an iPhone.

as i stated in my previous post in this thread, in my case i was sure it was the loud-speaker, i say "was" because i sold the phone, and thats the reason why i didn't come back to this thread since..
it seems there was something wrong with the loudspeaker(on the back of the phone), and it was, at least to me, one of those things where a person might not really notice unless you're looking for it.. my bad luck had caused me to flash a certain modem and the reception was bad, so once i reverted to the previous modem i was checking for the sound clarity and that was when i first noticed the static during calls..
then i realized it was coming from the speaker, as one good man in this thread suggested. i couldn't handle it though, i could hear it every time i make a call..
it didn't make a difference whether i was on 3g or gsm or both, it was always there, unless i went into airplane mode..
so i ended up selling the phone, and bought another, but before i had bought it i put my sim inside and made sure there was no static, and there isn't, whatsoever.. thank god.
i'm sorry i couldn't find any other solution to the problem, samsung service here had said they would replace the speaker, as the part comes on its own, unlike the case for the phone speaker, which, according to samsung, is bundled with the screen, and if i had wanted to change it i would have had to pay something like 200$ to fix...
those who have this problem, check if its the loudspeaker on the back of the phone is the actual culprit, and if it is, try to find a way to replace it or something, that is if it bothers you this much. or you can just sell the phone, there's a 99% chance those who buy it won't notice anything, because they're not looking for it..
good luck guys..

Galaxy note voice call echo

I just recently bought my Gnote from Newegg and found there is an echo when I make phone calls. I think the phone is a French version since there were french written on the phone box. Now it's just the people on the other line that can hear the echo. I narrowed it down to the mic on top of the phone. When I cover that mic hole, there is no more echo for the other person.
I'm wondering if my phone is defective or is there a setting that I can change to stop this. I tried turning off the noise reduction and that help reduce the echo a bit. The phone case I have on it doesn't seem to be affecting the echo. Has anyone else have this problem? Phone was already unlocked from the box so I assume it's been rooted. Please help.

I haven't noticed any issues with my Note so far but if your phone has already been rooted maybe its a software issue. Have you tried using a different software for it, perhaps one of the roms on the forum here. I am currently using rocket v8 with abyss note kernel 2.1 and things are great. I'm no expert but it's worth a try.

I also have this echo issue. This is especially the other end who notice this. I use a Swiss Sunrise SIM card. I tried another SIM from Swisscom and no echo. So i call Sunrise who is working on this.
So at the moment i cannot tell if this is a Gnote or Provider problem.
I will try the Mic suggestion but i thought Gnote has only one Mic??
Where are these Mic located?
I found where are these Mic located. In the quick guide comming with Gnote it is said that top Mic is used only when Speaker or video recording are activated.
Maybe this Top Mic is actvated all the time! How can it be deactivated?

Look here, same issue...

During the call, you need to go to menu and turn off noise reduction. This will solve the echo problem but is only set for that call, ie you need to do this every time.
There is a MOD for this:

However.. since I upgraded to Gingerbread 2.3.6 this problem seems to have disappeared for me.

I am GB 2.3.6, and i still have this echo issue.

Same problem here but only a few times. Thought the echo was caused by coverage reception?

Its mostly caused due to RAM shortage,e.g.if a large or too many applications are running in the background at the time when the call came in.

I've had this echo issue for the callers in the other end from when I got my Note in December. Two version of GB and now finally ICS and the problem is still there. Today I went to the service center and the changed a lot of parts in the phone (mainboard, mic, receiver ...) and when I got home the problem was still there. I've been troubleshooting this for a few hours and found that using the phone without any case has the problem, with a case it's worse. And, when I remote the back cover of the phone, the problem goes away completely. Anyone else still have the problem and experiencing the same thing? Just call someone, confirm the echo and then remove the back cover of the phone, for me that resolves the problem completely every time. So, what did Samsung do wrong here? Are the sound travelling in the back cover from the speaker to the bottom microphone? Are there any pressure made by the back cover which cause this? Why is the problem worse when I add a case on the phone?

My solution to echo
I had the same problem. My solution is/was simple -- hold the earpiece tight into your ear. The echo for the receiver goes away.
The echo was caused by the phone picking up the sound from the Note's earpiece. I always have the phone on max volume so this made it the worst.

Latest CM9 nightly turns dual mic off by def.. Fixes echo.

I got my phone completely fixed today. After realizing that removing the back cover fixed the issue, we also found that removing the pen fixed the issue. So, replaced all back plastic, new back cover and new pen, still problem wasn't fixed. So only thing not replaced was the screen, replaced the screen and problem was fixed. The service-tech told me after that the antenna part from my phone and the new parts was different. I had one of the first batches Note's that came to my country. Now the phone is perfect, even when I have it in a case which did amplify the problems before.

My note developed this problem after my charging post was replaced by the authorized service center. Probably something happened when they opened it and re fixed. When I complained of the echo problem they reluctantly took the phone but only to return it after hard reformatting which did not solve the problem.
I noticed the the following:
1. Echo disappears if the phone is pressed hard to ear thus preventing sound from reaching secondary mike.
2. No echo if back is removed and used exposing battery, etc. I am still puzzled by this as sound should still be traveling from speaker to mike.
3. After several weeks of experimentation, hundreds of test calls, reading several posts (many gave placing pieces of visiting card over speaker and mike after opening up the phone and closing the phone-it did not work for me even after several attempts), I found a solution which worked well.
4. Close/seal the secondary mike hole at the top with a sellotape and test. and it worked well. Then I opened up the phone (9 screws, removing back with priser, etc) and placed a small piece of vising card strip inside the mike hole and closed the phone. Thus no unsightly taspe is visible. You can even sell it in second hand market if you haste your phone!
No problem ever since. You can testy it yourself as it is easy to place the tape.

My experience
Sorry for my englisn. I wanna share my experience of fighting with the same echo problem in my note3. I tryed to solve problem about mounth. I have stock rom no rooted. When android changed to kitkat I anderstood that problem was in hardware. I opend my phone and tryed to isolate upper microphone. No effect. Yesterday I brought my phone to service. Master assessed upper and lower microphones by *#0*#. I heard myself that lower microphone was much more queit. He cleared canal of lower microphones and problem was solved!

[Q] Others can't hear me

Bought Xperia Z3C and from the first day some calls didn't work well... Others couldn't hear me about 60-70% of the calls, sometimes they heard like strong wind is blowing into the mic and when I put the call on loudspeaker then it worked, they heard me loud and clear.
So I took the phone back and ordered a new one, cause I really like Z3C, even more, if it would work with no problems
So my new, second Z3C, same green beauty - but same problem! I tried repairing with the first phone and tried doing the tests, neither helped. Only this time about half of the calls act like that. Sometimes if I put the call on speaker and then back, it works again, but not always.
So my question would be - Has anyone else had this kind of problem? And if so, what did You do? Is there even anything to do? Is it hardware or software?
There is no other phone I would like but it would be silly for me to try the same thing third time.

sorry to hear that,i guess that when you take the calls ,you cover the loudspeaker at the bottom of the phone

Similar thing happened to me, I had to yell first few days untill I discovered I had a bad habit from old mobile phone.
When i talk and holding the phone, my thumb is on the one side, three fingers on the other side, but that little finger is on the bottom, like i hold the phone not to slip down.
And the mic is positioned exactly so my little finger would cover it. That was my reason people couldn't hear me.
I doubt it's your case, but try to see if you do the same thing

Agree with others -- the mic is in a slightly odd place and I had to adjust the way I hold the phone to avoid blocking it in some way. Aren't the mics usually on the bottom left instead of the bottom right like the Z3c?

exact same problem

I have the same problem in All voice communication apps and normal calls.
If i test the microphone at The built in test i get no problem but in skype, Facebook and All other things that uses my Mic it cuts off and makes a windy sound. I was allmost ripping my own head off in anger and confusion because everybody i call is making me say things 5 - 10 times. And now i see im not the only one... What to do? Great phone beside that and headphone and aux volume is adjusting it self..

I had this kind of a problem on the latest firmware (.77) sometimes. How about you try downgrading to an older firmware? Like the .93 firmware which can also be rooted
Sent from my D5833 using XDA Free mobile app

Got the same problem. After disabling "noise cancellation" (not sure how it's named in English FW) in settings > Call problems is resolved.
But now everyone hears everything within range of the main mic and thats not cool.
Can anyone confirm its related to 23.0.1.A.5.77 Firmware?
On previous version didn't had any issues except phone went underwater and died, and new one is already on the newest fw ;/
Don't want to do root due to guarantee issues after this.

+1 the same issue,
serviceman flushed the original firmware twice
nothing helped, they even refused to refund saying that they can not identify the problem .
Farewell guaranty, I'll try CM mb that will help.
The problem is floating, suspect bad mic contact or bad capacitor installed.
both require disassembling for proof.
Service tests shows that mic is ok.
Does anyone know how to get voltage\capacity curves from mic without disassembling ? mb some test pins on the back ?

Sent the phone in repair and now it's perfect, I can whisper and people understand me

You had issues with the main mic - I do not have (luckilly) such an issue. Only 2nd has some problems, but if I launch service tests it records sounds fine. With different quality than 1st mic but records properly.

Mine was recording fine in service tests also (replay sounded ok), but it was apparently not sufficient in calls. I think the service test is very sensitive, with my repaired unit I can whisper at 10 cm and still perfectly understand on the recording.

Please post reply to those questions:
1. Do you have enabled noise-cancelling function.
2. Which mic you test in service menu?

1) Tried both, no difference
2) Tested microphone

Microphone in Z3C is the worst part of the phone
Im also have problems, or people Im talking to via phone, cause previous phone which I still have - SGS 5 mini - has very sensitive mic.
Both my phones are watter proof, also has special membrane, but when Im callling one to another difference are HUGE.
I checked 2 phones of my friends, and thier Z3C's have the same sensitivity, but the dont complain, as suppose they are usualy yelling
In SGS5mini I can rotate phone around the ear and still very louldy and clearly someone can hear me, thera are little diffrences ofcourse, but in Z3C where even when Im trying to have microphone close to mouth sound is much quieter - moving the phone little bit and conversation can be irritating.
It already pissed me off 3 times so much that I ended conversation, because of complaining of the other people.
P.S. Before someone will ask - yes, I disabled noise cancelling function from the begining, also trying different sound settings in call and sound menu.

SOLVED - at least in my case
What I did till today was:
disable any sound "improvements" in menu
cleaning microphone hole with compressed air
After test I saw little improvement, but still I was merely heard by other caller.
Looking mixer_paths.xml tried few times changing parameters and found the right one to rise sensitivity of internal mic.
Below are unchanged section that I'm talking about - in bold specific value that we can rise.
Code:
<path name="handset-mic">
<path name="adc4" />
<!-- 67 % of 124 (range 0 - 124) Register: 0x231 -->
<ctl name="DEC3 Volume" value="[B]83[/B]" />
<!-- 63 % of 19 (range 0 - 19) Register: 0x15F -->
<ctl name="ADC4 Volume" value="12" />
</path>
I choose value=92 as this found to be still safe (don't use to high values as it can damage your device) and I'm pretty happy now of my Z3C
Prepared MOD for this change to apply from recovery.

I've sent mine for repair. They said everything is ok, since repair service does not test calling in real life - just service tests, where this issue is impossible to catch. Had to ask them for "special" test - calling from my phone to somebody, and checking the difference between Noice cancelling feature turned on and off.

Hi any mod for stock ?
My wife have z3c everything was fine just one day start cut off world etc.
Will try with disabled reduce noise option
Any other solution ?

Guys I had the same problem, solved it today
Mine was running latest android 5.0.2(23.1.A.1.28) Z3 compact.
In my Music application(Walkman app updated to Music)-settings-Audio Settings- Mic sensitivity set to High.
Other person can hear me crystal clear

I suspect this is a Bluetooth related issue. I have my Bluetooth always on and when driving and calling there is no issue on car kit. I found an workaround, when calling before connected I press loudspeaker and mute unmute

Low in-call volume: can't get existing fixes to work, any ideas?

Hi! Running OP3T, OOS 9.0.6, simple TWRP/Magisk install with no major fiddling (did it mostly for the adblockers tbh).
A while ago I started noticing the handset speaker would sound really low in a call compared to, say, the phone speaker or wired/bt headphones. I'm not 100% sure when it started happening but I've been trying to solve this for about 3 months now.
It seems to be a common enough issue that it shows up in multiple sites, for instance https://innov8tiv.com/fix-low-call-volume-oneplus-3t-calls/ has several different fixes. I even tracked down the TWRP file they mention here to xda -- https://forum.xda-developers.com/showpost.php?p=72825218&postcount=9 -- but for some reason, none of those fixes work for me. I can't find any of the files they mention I should be editing anywhere or with any of those names, and the link to the TWRP file shows no mirrors. I can't find that file (by that name at least) anywhere else either. I've tried messaging Creeper36 here on xda (he's the guy who posted the original TWRP fix, and he's listed as the file owner on AFH), but no response. I've even tried installing Viper4Android and whilst my headphone/bt experience has improved, that's not really where my problem is, and I can't seem to figure out if/how V4A can even affect in-call volume. I think it's not supposed to.
So I'm running out of ideas and it's really annoying me. It's low enough that every time I get a call I scramble to find some form of headset before I pick up, and that's just annoying as hell. Does anyone please, for the sake of my mental sanity, have a fix for this?
Thanks!

I had this problem on mine and my mother's OnePlus 3T after 3 years use. Turns out the speaker grill is really good at collecting all kinds of scrap. I noticed this as I had ordered two new speakers for the phones, and when I was swapping them up I realized the problem wasn't with the speakers but with all the dirt clogging up the speaker grills tiny holes. After cleaning up, volume level was restored.
But I guess you could do a "dirty fix" by just increasing the volume hoping it will get through, and also hurting the speakers in the process.

How would you suggest I went about that cleaning? Toothbrush maybe? Slightly wary of poking through something and making it worse...

I'd say will need to dismantle the phone and remove the speaker to be able to remove the dirt between the grill and the filter as it's not accessible through the front simply by the means of a brush.

Hi,
I had this problem when I bought mine, since I bought it used. And it really was just the dirt on the speaker so probably nothing serious. You can get just a simple needle or toothpick and clean it but gently. If it still sounds low then you can disassemble it. Please, let me know if that works for you.

Rather than using something to poke INTO the speaker, is recommend using a vacuum attachment to suck debris out.
If that doesn't work, then disassemble the phone to clean it out. The difference is staggering.
