[Q] Does this device have two mics? - Galaxy S II Q&A, Help & Troubleshooting

Everything worked fine two days ago. Now, when I call with someone, I hear them fine, but they don't hear me at all. HOWEVER, if I put call to speaker mode, they suddenly hear me OK. Apps using microphone also work, I can record myself and it playbacks fine. I flashed new ROM trying to solve this issue, but it did not help. Only sense this makes is if this device have two different mics, but I can't find this information. Any ideas?

Yep. The main one on the bottom, the other on the top for noise suppression. Your theory makes sense because in speaker mode only the top one is used.

[Q] Problem with microphone

Hello guys,
My problem I am experiencing is with the microphone that picks up sound for videos and voice recording. In calls, it is fine, as the gs2 has 2 seperate microphones? One for calls and other for videos/voice recording.
Anyway, the problem started around 2 months back, it then disappeared after blowing into the microphone hole at the bottom. Now recently, it randomly began to not work again, so the same old static/screetching when recording was present, it even started to not record anything at all so I tried to vaccume it to get dust out, and it then started to record static and very distorted audio.
I left it a day, and WALLA! works, but now it has gone back to not recording any audio at all...
I'm not sure if this is hardware or software related?
Any light to be shed on my problem/suggestions would be really great, its still under warranty as well by the way.
Regards,
Carlos
It sounds like it may be damaged. I'd send it back for repair/replacement.
Incidentally, the SGS2 does have 2 microphones, but one of them is used for noise cancellation. It uses the same mic for both calls and recording. If it's 100% fine for every single call, but bad on video/audio recording then it may be that the recording level is a lot louder than the usual in-call level, and that's why you're getting different results.
Incidentally...

No sound in calls unless on speakerphone.

I've recently noticed that I don't get sound when making a phone call unless I change to speakerphone. I don't make many calls so I don't know exactly how long it's been happening, but I first noticed it a couple weeks ago. I know that the other person can hear me fine when I'm on either setting. I've also switched ROMs, from Alien to the new CM7 beta, with no change.
Has this happened to anyone else? Is it most likely a hardware problem? I've never dropped my phone or anything, and it's only 3 months old. Does anyone know of an app that can test the normal phone speaker, because all other sounds have been working fine.
Thanks for any suggestions!

My guess is it's a hardware problem. I would have it checked out by your mobile phone company.
You can also look up "hardware test" in market and you will find apps there you can use to test your hardware. Sorry not to recommend one. There are many there if you look them up.

Thanks for the response. I looked for an app already and didn't find anything useful. There were tests for just about everything else; touch screen, sensors, GPS, etc., and only two that I found that had an audio test at all. However, neither of them allowed me to specifically test the "phone" speaker.
I just think it's weird that all other sounds work fine. I'd really rather test it before I send it in to Motorola.
Thanks again!
This was a common issue on the Motorola Defy's. I had to send mine to Moto for repair. If you're within a year, AT&T will replace it.
I am having this exact same problem with homebase. but mine is intermittent it will work straight after a reboot
More sound issues
In my case I just updated from Froyo to Gingerbread, everything was working perfectly, when suddenly i stopped listening to the earpiece, the loudspeaker still works during calls,
On the other hand, if I try listening to music or any other sound, the loudspeakers dont work... any ideas of what could have caused the problem? It feels like some sort of driver issue, because while trying our the earpiece and loudspeaker during a call I was able to listen to one second of conversation through the earpiece...
i do have exactly the same issue...
putting pressure just beneath the fingerprint scanner, makes the earpiece work for an instant ...
its definitely a hardware issue...
m really fed up with dead spots on touchscreen n this earpiece issue....

[Q] Top speaker quality in viber

Hi,
I was using my old Galaxy s3 to call & txt fiance using viber in states, now that I have sold it to mazuma mobile I have used viber to call her for the first time on my z2 & I could barely hear her at all on the top speaker & had to put phone on speaker phone just to hear her , normal call quality is pretty good on mobile calls, volume was up full. She could barely hear me as well, I turned off noise cancellation in call settings & she could hear me a bit better but said it was still quiet.
Just wondered if anyone else has experienced this?
Cheers.
Have you tried moving the phone around on your ear? Sounds silly, but because of the placement of the speakers, its not as natural as other phones i've used imo (or maybe its how tall the phone is). I found the same issue at first, then i moved the phone around on my ear until the speaker and my ear lined up right and the sound was normal.
Yeah mate, moving the phone around my ear was first thing I tried, I don't have issues with normal calls but speaking to her on viber it's almost like the speaker volume is set really low & I could barely hear her at all, since I call her in the early hours I would rather not have to put the call on speaker phone.

Ah okay. I did a quick google search and it looks like its hit or miss for some devices, so it might be on their end. This thread has a Viber rep responding in it to the same problem, or at least a couple months ago he was(no real solution, other than reporting it).
http://forum.xda-developers.com/showthread.php?t=2307492
Also there's an app suggestion in there that a member says helped, and another one would be master volume (i think thats the name). I don't really use Viber, so i'm not much help other than that.
Cheers again for the reply mate, have checked that thread out & also posted in it hoping they will still be checking it, checked the apps mentioned in play store & most haven't been updated since 2011, I do think the issue is like you say more on Viber's end as the volume was fine on my now sold Galaxy S3.
Might have to check out Line or similar apps & get her to do the same as Viber is almost unusable due to this, connection quality was excellent all through the call so I think Viber just need to update or optimise it for the Z2.
Same problem man, here is a fix that worked for me, note 3 international version:

Google Hangouts Echo

My wife got her 5x before I got mine. One of the things I noticed right away is that when video calling via Google Hangouts, the audio had a lot of echo and distortion. Now that I have a 5x as well, it sounds downright awful when two 5x phones are in the same Google hangout.
The funny thing is that overall audio quality is pretty good. Even videos taken with the device sound great.
Has anybody else tried Google Hangouts and experienced something similar? I am just trying to troubleshoot what might be wrong here. Using two Galaxy SIII's over the same connection, the audio was great sounding. So it seems to point to the phone. Anybody else have similar issues or suggestions?
Yes ....sound terrible for me too..

Same here.. adjust the volume. Mic and speaker feeding back.
This is pretty annoying. The mic is right next to the speaker on the bottom correct? Basically not usable without messing with it. I need to mess with it some more. Is the call volume the mic sensitivity or volume? It has a mic icon.
Just tried from 5x to ipod and it was better. Before I have only tried 5x to 5x. Strange it seems better when video is off and just audio call.

Hangouts uses audio codec Opus which is known as a modern low latency and high quality codec, which demands some CPU power, sometimes more than modest phones can sustain. Besides Hangouts video is one of the most bandwidth consuming - it takes 15M/min.
Google is probably the only one using exclusively its own servers for voice transmission, all others use peer-to-peer network. Fortunately Hangouts is right now into the process of switching to peer-to-peer network and it is a promising maneuver toward improvement of voice transmission.
Try to cancel video transmission and adjust microphone gain. When peer-to-peer transmission is in function, the voice improvement should be significant.
My Nexus from 2011 has no issues, so I doubt it is CPU related. I did get a message about it switching to peer-to-peer too. I have adjusted every volume and it just really doesn't work well. The issue is feedback and I don't think the transmission protocol or CPU has anything to do with that. Thanks for the info though.
Well I found a workaround. If you change the speaker used during the video call it will work. One person has to use the headset speaker. If both are using speaker it is horrible. It works fine, but the volume is way lower so not the best solution.

This is NOT acoustic feedback. It happens even when both parties are using earbuds. If the other party is using a 5X, you hear the echo. If you are using a 5X, the other party hears the echo. For some reason the 5X sends received audio back to the sender. I have no idea why. It's very frustrating to not be able to use the exact app I switched back to android for.
same here. tried several phones (iphone 5s, nexus 4, htc one) and tables (nexus 7, etc). got no problems with all other devices, just when the 5x is in the loop others will hear an echo
Same here, this is so annoying, I can't make a call or video call with the speaker ON (skype, line, whatsapp) or the others hear themselves too loud.
I can use a headset but that's not convenient!
This wasn't mentioned in any of the review, Call or video call is one of the main reason why we buy a phone!
Is there anyone who doesn't have this problem.
Tested it on EMUI, same problem.
I didn't test it with a custom ROM yet
I have the Echo even if the video is turned off.
I checked id on three deffferent devices.

What about normal call using earspeaker or handsfree?
Maybe it's a Hangouts problem?

Try to used an old version of hangouts as also. Get it at apkmirror.

Have you contacted Huawei support line?
That's a terrible bug or hw malfunction and it needs to addressed right away.

I think it isn't Huawei issue, the same hapens on other devices (OnePlus One, Elephone P9000, Samsung tab, Samsung S3)
So I do not know where to look for issue
I told you it's a generic Hangouts problem.

Microphone not working when speaker activated

Holla fellows, on my LG G5 I am facing a very bizarre issue. When I activate my speakers my microphone stops working. when on earpiece they work like a charm. Also microphone didn't work when used my other applications like skype or hangout, but while using earpiece they are perfectly fine. Anyone else got this issue on G5 or anyother device ? Any suggestion or advice is greatly appreciated.
I'm having the same issue. Literally just got the phone 4 days ago. Pretty happy about it. Have you reset?

Yes, I tried resetting via backup and restore under settings menu
Reset mine and thought about the mic being housed in the battery holder bottom part. Why not take it out and clean connections....mic works great now. Dunno if from reset or alcohol cleaning connections. Give it a shot.
Same here i purchased the phone on 5-5-16 it will reboot on its own almost everyday till 5-19-16 when it completly just gave up and wouldn't turn on. So i went to tmobile and they replaced it for a new one. But now the replacement gave up yesterday 5-28-16. It has managed to turned on once but the device was too hot that i turned it off to cool it down and it wont turn on anymore. Sucks that is long weekend and i wont be getting s replacement soon.
I too am having this issue, however mine has one other weird glitch. If i put the phone on speakerphone and talk into th phone like normal (phone up to my ear) i can hear myself in the phones speaker faintly and the mute button does no work at all. Works fine on normal mode but not on speakerphone. To me this is a software issue vs hardware issue, I bought the phone second hand so I dont really have any warranty. Anyone have anything to offer up to try? Ive tried a different battery module base and no luck, same issues. Its almost like the phone needs a entire reflash done to it. Other then this issue the phone rocks.
The phone is a Canadian H831 model.
I had similar issue with older device. Read on some thread and they suggest disable Google now. It worked for that device. I am not sure if it will for you guys?

Thanks for the link @marac1993 will check
I had the same problem. It turned out to be a "hardware" thing. There are two microphones, one at the bottom of the phone which works when on earpiece, and the second one on the top of the phone (above earpiece) which works when on speaker mode. I cleaned the first one several times without noticing there is a second one on the top. It turned out that the second microphone was blocked by some dirt. I cleaned it and now it works like a harm when on speaker mode.
