[Q] Weird voice echo problem

Hey guys, i really need your insight on this.
I bought my N7000 today with 2.3.6 installed. I quickly realised that anytime someone called me or me calling anyone, the other end hears his own voice, loud and clear.
The weird thing is that this is happening ONLY if the plastic back cover is on. If i remove the cover even when i speak, the echo goes away only to come back when the cover is placed on the device again.
I have tried using another SIM card, switching to WCDMA/GSM mode, updating to 4.0.4 with no luck. I have been reading a lot about similar issues with the Galaxy S II, but rarely on the Note.
Am i dealing with a hardware issue?

Just search around.this is due to the second Mic picking up the sound bytes. You will find in the forum how to fix this..with detailed instructions on how to open the phone and fix the echo from the Mic on top t

Took it back to a Samsung service point. Turned out it was a faulty mic assembly. They replaced it and everything is A-OK now.

I just dismantled my 4x HD!! And replaced the headphone jack!

Thought I'd share what I've just done! I (rather stupidly) was listening to music while working on my car - the only headphones I had to hand had a big size (6.35mm) headphone jack, so I had an adapter in there too. Al this meant a rather large lever poking out the side of the phone. I'd obviously bent down to do something and wrenched the socket to one side. The 6.35mm adapter had been bent over and broken... and when I tested the phone I found the socket was broken to - only working in one ear
I went on line and found this guide to dismantle the phone! http://www.youtube.com/watch?v=kGD64_g-ssE
Actually nothing to it! Except Even though I do have a very small set of screwdrivers the screws used on the phone are really small!
I bought a new headphone jack from here for £20.08 delivered : http://www.etradesupply.com/catalogsearch/result/?q=lg+p880
And it arrived in the UK in less than a week from the US!
Out of interest the headphone jack can be removed without any of the other circuit board connectors, or the board itself being loosened.
It also houses the proximity and light sensor, I did put it back together and find the proximity sensor was constantly reading 'near' (using the hidden menu 3845#*880# )So I quickly opened it back up again, removed and replaced it one more time. Now it works great, I must have had it badly placed

Well, at least the video was not published in vain
Nice work!

Thanks for decribing this.
I guess I have to replace my jack, too, since it doesnt hold my headphone strong anymore and sometimes the electric connection of the headset mic gets lost.
I have found the jack for about 5$ incl. shipment at DX:

I got the ETrade one. Also I think parts4repair.com sell parts for the p880.
The little arm you can see poking out actually bends and doubles back under the socket part. I found my screen wasn't waking up when I moved the phone away from my face, I just opened my phone back up and padded it out (between the socket and the sensor part) with a little shim (card etc, I actually cut off and used a little piece of a lens cleaning fine cloth) and now the screen wakes perfectly for me! That was my biggest gripe (apart from huuuuge lag when the browser opens!) and i no longer feel I need to ditch the phone!
Don't lose the little square rubber part that the sensor part sits in! And I recommend using a tiny flat-head screwdriver for the phone's screws, the posi-head screws are so tiny I couldn't get a good fit, and it's all too easy to ruin the tiny screw heads.

on/off button doesn't work.
Anybody know how to fix the on/off button. ?
I'm really pissed, I've had the 4x only 6 weeks and don't think I overused it.
button placement and size isn't that great to start with.
I flashed Arararagi vanir 4.3 and it was running great too.

I've never had any problems with the headphone jack, have my phone for about 4 months now

The on/off button? buy a broken 4x?
I took mine apart a few months back to clean the inside of the screen.
Had to send it back to LG as had a few issues regarding call quality and the screen not coming back on when you take it away from your face - Just got it back and they replaced a case and a lense? Not sure what lense though.
It also said Software update - They sent it back with ICS

they probably even permanently locked your bootloader, if it was unlocked your "phone not turning on when moving away from ear" problem was sensor miscalibration that you could've fixed easily.

No. it was new when I bought it.
Had it for 6 weeks before the power button stoped working.
just used it everyday, rooted it, a few roms, then daily use.
i expect something like this from a cheap chinese knockoff, not an LG 4x. i had a star b92m where the screen became unresponsive.
next time I'll get a SONY XPERIA Z.
The 4x has been in the shop for two weeks already. .

OverVoltage on the headphone jack =(
I believe is overvoltage, I connected a plug from my radio for louder music(as I usually do) but wasn't working, and tried moving the connector on the radio and instead of plug in input from radio, I plugged in the output from the radio, a sound came from the radio and that was it, no more sound signal from my P880, I love this phone, I'm so angry about this.
So I checked with earphones and nothing, just noise, no volume up or down, and the headphone mode is turned on all the time, do you now a site where the earphone jack flex can be delivered to South America, Bolivia? and if you have some other suggestions or solutions specially for taking out of headphone mode, I even can't make calls! thank you in advance

The two parts places I have used are I have used are etradesupply and parts4repair. There's probably lots of others out there. Not sure where they ship to though

Echo (Echooo....Echooo....Echooo...)

Hi XDA'ers
My wife got an unlocked i8190 from carphonewarehouse on UK Vodafone in November last year. As it still has relatively low volume sales I have not been to find an answer online so would be grateful for any input.
Not every time but almost, and seemingly more often with mobile to mobile calls the caller at the other end gets horrific echo of their own voice. (i.e. if I called you, you hear your own voice echoing) the caller finds it very hard to hear the Siii mini caller. Bizarrely this is rectified by putting the Siii mini on speaker or using the wired headset.
This makes me thing the mini's front speaker/earpiece is feeding back to the mic somehow. (As far as I know previous samsung echo issues were at the galaxy end and related to noise reduction processing. As the mini has no secondary mic nor noise reduction this is not the issue here). Oh the sim is fine in other phones and my 02 sim (fine in my Sii) causes echo if used in the mini.
Anyone have any ideas of a fix? Anyone had similar issues?
Cheers Tom
(read on for a thursday night rant.............)
Attempts so far; I initially updated to the latest firmware OTA (nonewipe) and no change. Then I went to the Samsung Smartservice at Westfield's Samsung store where they used KIES to update non-wipe and still no change - strangely there was no echo with their landline but then I called the guys SIII and he said it was awful.
So they sent it to their service guys (intercity telecom, birmingham) who took 7 working days to full wipe the device and reflash i8190XXALL2 (BuildJRO03H....) which I think is what it was already running.
Surprise surprise it is still echoing. The receipt said 'could not replicate fault' (If so why not contact S Smartservice or me?) Smartservice said they could not replace the phone until the third failure to repair. I tried to call intercity today and was told I could not speak to an engineer as it was a closed workshop. Therefore I should apparently send the phone back to them again with no guarantee of a different result. Brilliant, why can't Smartservice contact them to sort this out?
I also spoke to carphone warehouse who said that they need to send the phone to their engineers, if they can' t fix it it will be passed to samsungs engineers (brilliant as it has already been to them!) and then will be back within 28 days. In store I was told if the fault persists, it will be sent back twice more (28 days each) before an exchange will be considered (after phoning customer services we were told two weeks then to samsung if not fixed an exchange immediately). The latter sounds more reasonable, but the phone has done this since day one and borders on unusable. We have had it for 11 months and it has been away for almost 2 weeks, either way (intercity or carphone warehouse) we would be without the phone for 1/2 it's life by the time a replacement is offered, presuming it cannot be fixed.
Any advice if no solution is forthcoming?
Cheers
Tom

Take it back and don't give up, this clearly is a hardware fault. I don't have this issue on my S3 Mini and I don't believe anyone else has it for that matter.
Be persistent and they'll have no choice but to replace it.

I am having the same problem and sent my phone back to Orange who said they had solved the problem, with software and shielding. But my problem continued, as with Tom, until I took the cover off. This was a Supergets Black Wave Hydro Gel Case I had bought on Amazon. I have yet to discover whether other cases will have the same effect.
The hole for the microphone was not completely aligned and I have enlarged this but I am told by those ringing me that this doesn't seem to have helped much.
Maybe this helps,

S3 Caller Voice Echo Solved
I'm disappointed with my S3 Mini had it two weeks and same thing. From scouring the net it seems it doesn't matter what cover you use it has the echo problem. try this ............... while you have the other person on the line, twist the phone with it's protective case ever so slightly and hear the caller tell you how it goes away and comes back!
I think the tolerance of clearances between the phone components and the case is a problem.............. Samsung couldn't care!!! how they actually managed to take the cellular market worldwide is beyond me especially since it seems several models of their phones are having this problem!
seems like the phone suffers from mechanical feedback through the casing ( adding a protective cover applies some force to the phone casing and causes feedback!! tolerances are way too fine!!! )
I eventually fixed it myself, I took the back cover off, took some of that plastic ( pink polystyrene like ) foam that you find computer hardware packaged in and cut this to size to fit the back side of the speaker. I cut a tiny square out to fit over the mic too.......... the purpose of this is to leave some air between the case and the speaker and mic!
seems to work, if you try it and it works for you let's hear about it
good luck

Many thanks to Kramski. Initially the polystyrene round the speaker didn't change anything but worked well when I added in a piece over the mic

My friend has S1 and he has the same problem.It looks like some samsung models have this problem.

Almost all models and faulty productions, just depends how huge the issue is. Second or no second mice, still you would have to open split your phone to isolate the mic from the rest of it, align rubber mic cover part as IT SHOULD HAVE BEEN and add more insulation around the speaker as the case is resonating, being made of and is rather lightweight and not adhering perfectly to the battery and the phone body at 100%.
I cured my S2 in 10 minutes, never had such prob with it again. My kid's S2 nor my wife S3 mini presented the same issue.

This is crazy. In my Galaxy S III mini the "echoing" problem was ... in a 2$ plastic cover. Not the phone battery cover - but a case cover. Checked this several times with and without so quite sure. Also with cover case on, when on speaker phone there was no issue - so it looks like the sound was passed from the speaker/earpiece -> ear (attached to the speaker) -> cover case (possibly resonating) -> microphone.
"Drill" a wider hole for the microphone and this is gone, just 2c

Microphone problems

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:

[Q] Moto X Microphone(s) low (very)

Had to get my screen replaced, it was cracked and went black, on my 1st generation Moto X.
Got it back, everything seems to be working except people can barely hear me when i try to call them. I tried leaving some test voicemails, on regular handset call, inaudible, on a speakerphone call, can barely hear the message, sounds very far away. Was something done wrong, did something break?? On a voice recording app, same effect.
I tried factory reset, a cache cleaning app, and tried looking at settings but dont see those mentioned as solutions (ie. voice privacy)
I came here, to the pros! please help

The little hole to the off centered left may have got some adhesive in it. Personally I would probably take a needle and try to scrape around the inside of the hole, making sure not to stab the mic.

Is it advisable to try and correct this by taking the unit/ Microphone module apart? I am pretty confident with mechanical/electronic things.

I mean if you can't get anything out with a needle or Sim tray remover you could take it apart, but remember that'll void the warranty. Also I am just guessing that there may be gunk over the mic and I could be totally wrong

well the screen has just been replaced so I am guessing the warranty could be void already. I that a simple procedure ? to get to that area? I tried already with a pin.

my dad is having the same issue.. he can't use voice typing or voice search anymore but if you hit or blow on the mic it does show that its hearing something, but only if your lips are basically touching it. anything further and it doesn't pick it up. Any ideas?

i noticed that On Smart Voice Recorder, if you go into settings and turn off auto gain control, you can recalibrate it, then it seems to notice your voice better(SVR does) and you can make a recording and can listen to it more clearly , although slightly grainy, but doesnt apply to the call app, so Im wondering if a global calibration can be done in settings or if another call app can be installed to allow for such settings.

I have been having the same issue recently. I have owned the phone for about a year and it has been fine up until a few months ago. The hole looks clogged and I've tried cleaning it with something thin enough to fit but there hasn't been a huge improvement. The sound isn't VERY low but it is much lower than it should be.
