Microphone issue - Galaxy S II Q&A, Help & Troubleshooting

i speak with people on my phone and the person on the other end complains of poor call quality The minute i turn of noise reduction its better apparently.could this be down to my card causing the microphone to behave funny to perform this function? really don't want to take my phone in for repair!
any others with similar issues and if you have resolved it let of know,is this fixable by Samsung releasing an update?

Are you using an external case / cover to protect your phone?
I have found that somehow using a case alters the acoustic properties of the phone, causing noise reduction to fail / malfunction. Try removing the case / cover, when you make a call.
Someone really needs to make a noise reduction calibration app for this phone.

tested this and you are right! might look at the official Samsung case since that doesn't cover the Mic only thing that concerns me is it doesn't cover some of the edges!

I have the same problem. I don't have a cover, just a screen protector. The protector does not cover any holes. It has three openings... For the handset speaker, front camera and home key. incidently it does not have any holes for the light sensor.
What kind of cover did you have?

I had one of the 3.95 ones from play.com that was black and had the S design on the back.
I tried to modify it to expose the mic a bit but it still did not work.
I guess I would have to cut away the front area of the bottom section completely which would look rubbish!
I cant quite justfy spending more than £9 on another case though!

[Q] Mic problem solved by samsung service center

hi my friends were complaining that my voice was breaking and vv low during calls. took my mobile to samsung service centre. they opened it up and removed a white plastic part from near the mic. possibly this was blocking my voice. now voice is clear and no complaints. pls see attached images of part that was removed. pls tell me what is the use of this part and hope it does not effect any other functions of the phone, kindly refer to both images i have circled the white part removed in red. asked 2 ebay vendors selling this part for replacement they say that the stock of this replacement part also does not have this white covering and below that there is the mic. any thoughts

Not many Samsung hardware engineers on this forum I guess.
come on guys you can do better. waiting for replies. i had the guts to get my galaxy S2 opened to solve this problem
Looks like just what you said, a piece of plastic that is used to insulate it, and/or block dust from entering thru the mic hole.
Ah - that's the temporal distributor. When you speak into your phone it can take a few seconds to convert that to a digital signal, transmit it to the other person and then convert it back to an audible sound. The temporal distributor uses tachyon particles to convert the audio to digital AND send it back in time, so that there's less of a delay. It just means that people will hear you a few seconds after you speak, but no-one will know that unless they're in the same room as you.
Urm... Wow? My SGS2 can send out signals faster than light?
So it uses a Tachyon Digital to Analog convertor (DAC)?
Urm... where is the flux capacitor located, and if I travel at 60mph, does it take me into a tunnel with swirly lights then reappear somewhere else either in the future or past?

No mate - that's at 88mph
Incidentally, travelling faster than light wouldn't make you go back in time. Light is all about perception, not reality.
thanks but since this part has been removed from my phone by the authorized service centre, will it affect my phone in any way. i am really worried now and from where can i get the replacement for only this part. anyways i received the below reply from an ebay vendor selling replacement mics
Dear varn.dhir,
Dear friend,the plastic part is not have any specific use,please be assure.
Thank you for your attention.
Good day!
no.1-tech????
hi but my old phone plastic part also damaged thats why i ask is there any specific use of this part and is it there in all phones.
Dear varn.dhir,
My friend,our item has the micriphone there but don't have the white plastic part,you can change it from the old one in your phone,it is easy to replace.
Thanks.
Regards!

Code:
That plastic piece is not supposed to be there.
There is another microphone on the top of the phone, you can see it in your picture, and it hasn't got the protection.
That protection is only used during production, the microphone is picked up by a machine using vacuum, so it must have a flat surface. The protection must be peeled off before assembly of the phone.
It is a mic grommet, it should be there.
So nobody else got this piece of plastic? Didn't check by myself...but also got this damn bad mic -.-
I had it. Just took it off and the mic is less worse now.

are you sure this plastic piece is not supposed to be there. have you checked your phone. seen a disassembled phone on ifixit it had this plastic on the mic. really confusing. samsung needs to answer how can they leave things inside the phone that interfere with normal performance of the phone

why not give it a try but make sure the samsung technician opens the handset in front of you and returns the plastic piece back to you. unfortunately i was not returned the plastic piece.

Oops! Sorry, I took a look at the service manual now. I only saw your pic before.
That part is called a grommet, usually made of rubber, it is supposed to absorb vibrations from the case and not transfer them to the microphone. Also helps to route the sound from the hole in the case to the microphone. Yes, it should be there, but it's not going to affect anything else but the sound quality.
Sorry for the misinformation.

Here's the service manual.

Don't worry too much about not having the grommet in place. If your voice can be heard fine by the other party, there's nothing else to worry about.
Except water and dust.

Holding my S3 makes a "crack" noise

First, my phone works fine.... this is not a big deal but it bothers me a lot.
A couple of weeks ago I noticed when I was holding my S3, lightly squeezing the edges or the back cover, the phone was making a sound like it's not well assembled.. like it is loosen... (like a low "crick" or "crack" noise inside or something)... I don't know how to explain it better..
Anyway I found out that if the battery is removed, squeezing the phone sounds just perfect, very well assembled with nothin loosen inside (no "crack" noises)... So its obviously the battery that seems to be causing this...
Is this just happening with me or its a ordinary problem?? Is there something that I can do to stop this?
thanks!
Check none of the back cover clips are broken or any hairline cracks in it.
Buy a Nice and cheap backcover from ebay. Maybe yours broke.
Skickat från min GT-I9300 via Tapatalk 2
My SGS3 is international unbranded from phones 4u UK. Never Dropped. My SGS3 also has this problem.... If I press the back cover at the top in between the camera and groove for removing cover I hear a crack or creaking noise. it may be the part of the problem with the back covers when the phone was originally released, Although they said that was a problem with the finish. Doesn't bother me but it is why people are always slagging Samsung's design/build quality.

[Q] Xperia Go front microphone seal

Hello,
I bought a second hand XGo in not so good condition (screen had already been replaced). It's missing the USB and Earphone flaps and the back cover is kinda broken. I'm thinking about buying some replacement parts (http://goo.gl/SiaT3w) but I've also noticed the front microphone doesn't seem to have any kind of seal to make it waterproof.
Does anybody know if the front microphone needs some kind of seal or if any other parts need seals? Or do you think the flaps is all that is needed to make XGo waterproof?
Thanks.
every opening of the phone is either sealed or covered with flaps to make it IP67 certified water resistant.
you can buy back cover and flaps to re-assure the water/dust resistance of USB port and audio jack.(if replaced properly).
the front and back speakers/microphones, camera, led all are protected. but there is no safe way to know that for a good old second hand set.
if there is some hardware damage, there are chances that the protective coating of these openings might get loose and eventually fail in pressure.
i recommend you to replaces flaps for dust resistance, and some splash resistance, so you can wash your phone. But NEVER EVER go in pool with the set. it is not safe at all to swim with the phone.
feel free to use the covered phone in rainy storms, i use it too ! :highfive: (sometimes i even put some water on it to cool it down after hours of gaming ! )

Hi,
I bought the replacement parts and they finally arrived. I noticed on another website something that seems to go between the microphone and the front cover (http://goo.gl/78x4WN). Could anyone confirm this is the seal for the main microphone? Sadly I couldn't find anything like that on eBay.
Thanks.

No information on official website about g3 tricell. Is that official account on ebay?
Are those pictures supposed to be true representations of the actual case? I noticed there aren't holes for the IR blaster and top Mic.

Really ugly, buying a smartphone with a wonderful design like the G3 and wrapping it into a concrete block

I ordered mine earlier today, and its supposed to be here middle of next week
Just ordered, when it arrives im turning every option back on and brightness 100% all day. haha
When you guys get it in let ever one know how it is. One of the few things I want to know is how are the rear buttons? That's the main thing really. Other than that only other small worry is the rear speaker volume after the case is on.

I believe it is. Note that the back speaker holes are actually on the bottom. The battery would be on top of the speaker so the closest way out would be to the bottom. I am not terribly enthusiastic with ZL's new design. I wish they stopped trying to out-ugly the Otterbox and made the smallest possible cover as before.

I didn't even think about the battery covering the speaker. Has that been confirmed? That's kind of a deal breaker for me. Glad I haven't already made the purchase.

I have not seen the actual G3 battery, but I've seen their batteries for other phones. They way they achieve their monster capacity is that the battery does not just occupy the battery slot, but pancakes over the whole back surface of the phone. It does not reach as high as the camera, but everything else on the back gets covered up. In addition, I can't think what other purpose would have the four holes on the bottom edge if not for the speaker. You can see both the holes and how the battery covers up the speaker in the third picture of that ebay link. OFC it would still be muffled that way.
TBH, even though I was a loyal customer previously, I think I'll pass on this battery for now too. My reasons are:
1. I need an everyday use device, not a ruggerized brick that I could use as a weapon in a tight spot.
2. Covered ports - in addition to finding a dock compatible with this monstrosity, I now need to fiddle with port covers
3. Muffled speaker. I spend plenty of hours on teleconferences and a loud speaker is important to me.
4. I finally jumped on on the wireless charging bandwagon and there is no going back. I just love the convenience of just putting the phone down and picking it up whenever without messing with connectors. I bought a couple of chinese TYLT ripoffs for home and office and a one touch car phone holder with wireless charging. With G3s excellent stock battery life, I am covered for day to day. I also applied for their spare battery promotions, so I think I'll be OK for flying/traveling as well. I will test that theory soon.
Didn't realise the speaker covered up until after I purchased. If its bad when I get it, I may just cut a whole out haha. Smh. or end up hestitantly using it.. hope its not the deal breaker. imam miss wireless charging too. But that extra battery life will be extremely handy
I tried to search another alternative and found this
http://www.ebay.com/itm/3800mAh-Bac...Cell_Phone_PDA_Cases&var=&hash=item19f2d72b40
and
this from mugen.
http://www.mugenbattery.com/mugen-power-extended-6200mah-battery-for-lg-g3/
how did you think for this extended battery ?
On their other products with rear speakers, they leave a channel under the battery where the speaker is and have a hole in the bottom of the case to direct it out. It's not ideal, but having a rear mounted speaker isn't really ideal either. If they are doing this on their G3 product, it should be OK.

Q: Looks like over sized case covers the back speaker is this true or is this just the picture. If case does cover the back speaker how does this work.
A: Thank you for your interest. ZeroLemon has manufactured the case and battery to reroute the audio to the bottom of the case. Rest assured this does not render the audio of your device. Please let us know if you have further questions or concerns. Regards, Holly
Mine came today and I love it. Adds much needed thickness and heft to the phone. Speaker doesn't sound attenuated. Buttons on the back can now be used without fear of fingering the camera.

Do the buttons work every time ? Also dose the case interfere with the camera, my g2 zerolemon case was not too good. The camera (especially with flash) would make pictures look bad. On the pictures one corner was blocked pretty bad. The buttons work 7 Times out of 10. Hopefully the fixed All that for the G3, if they did I'd love to have it.

Roxfit cover

It's been a while since I've posted on XDA... Found this ROXFIT PRO TOUCH case.... Premium Quality... I just checked the link and it's currently out of stock... Keep checking and get this case! You'll love it!
https://www.amazon.com/gp/aw/d/B06XD52Z7G/ref=yo_ii_img?ie=UTF8&psc=1
ROXFIT Cover is back on Amazon with limited stock, hurry and order yours. I have to be honest tho, you'll love the look but it'll take ya a couple of weeks to get use to the case but I promise once you get use to the case, you'll love it! Hit the Thanks button if this helps.
Bought this case 2 weeks ago. Very good build quality. The semi-transparent, touch sensitive cover doubles up as a brilliant privacy filter/anti glare filter. When viewing messages or other text through the cover, you can only see what it says if your face is within 2-3 feet of the screen and *directly* in front of it. Any other angle or distance and it's super blurry. It's also very good if you need to view a notification or the time late at night during sleep hours, as it doesn't emit a glare.
Downside is that the proximity sensor doesn't always detect the cover because of the semi transparency, and as a result sometimes the screen is still on during a phonecall and buttons can be pushed accidentally. I have already gotten comfortable with this though and with unnoticed adjustment I now no longer have any issues with this particular problem.
One last thing, the plastic on the back is a fingerprint magnet. If you pride in your phones current shimmer/shineyness, this case quickly turns it into an intrinsic artwork of pinky marks.
Seems fragile
I just recived mine and I am very disapointed about the quality, I want to be optimistic, but I fear the front "semi-transparent" part will be very fragile (as in the HTC dot view of the One M9).
So does anyone who had it for a longer time could reassure me on the quality of the product, or tell me right away if it's of poor quality ?
Thank you for your answers :good:
PS : is it dangerous to turn the front part all the way to the back ? will it tear the plastic junction down or is it possible ?

Can we set the phone to do different things when opening the flap ? Like on the official case for the xz? and what about the automatic brightness? does the sensor turn the brightness down when you close the flap?

yes kinda
So, is there any kind of feature that keeps the transparent flap closed (as opposed to letting it flap around freely)? The huge problem with the official XZ style cover was that the flap was flapping freely. If one kept the phone magnetically attached to car's dashboard, the flap would constantly flap open and closed as the car accelerated and decelerated. That effectively made that cover unusable. Is this problem fixed in Roxfit cover?
