S7 Edge Mic/Phone quality - Samsung Galaxy S7 Edge Questions and Answers

I'm having this weird issue where my phone is picking up sporadic wind noises (it sounds like someone blow wind into the mic) as soon as I stop talking (usually lasted a sec)
It happens almost everywhere except for a dead quiet place (on the roads, in a shopping mall)
I did a loopback using *#028# and confirmed it myself listening to myself talking while walking on the street.
Both my mics are working fine.
Is it a noise cancellation algorithm problem? My old Note 3 doesnt seem to have this problem unless I am standing right in front of a standing fan.

You sure it's not picking up you breathing? Not trying to be funny.

problems with the microphone?

I got mine yesterday, everything works fine except its microphone's quality. The other people hear me like I talk from distance away.
Is this common problem or just mine?
Thank you
This is something that I experienced initially when I got my Atrix, I resolved it by moving the phone up closer to my mouth. I tend to let the phone hang from my ear where I hold it near the top and it put's some distance between me and the mic. I'm a former iPhone user and was lazy with where the phone sat on the side of my head, once I made this change though people have said I sound clearer than when I was on my iPhone.
I can't talk closer, the speaker is exactly on my ear. It looks the microphone has very bad sensitivity. Too bad all Motorola cellphones i had in the past they had excellent quality.

I have same problem, I turned off noise cancellation and got some improvement. I'm pretty sure it is a software issue. I also put a clear bra type case on it from some 3m stuff I have, I didn't cut out for the mic on the back. I'm hoping this too helps but have not tried yet.

Phone mic oversensitivity [FIXED]

I take no credit for this, I remember seeing it in a thread here (which I can't find now). Been plagued with alot of background noise always coming thru the mic whenever I call from anything less than a silent environment. Someone here suggested a small piece of tape placed over the mic hole on the inside of the back cover with a small pin hole poked thru effectively attenuating the amount of sound coming thru to the mic. It works! Took it one step further though cuz I always seem to get alot of resonance from the cover itself so I cut a 1×1 piece of duct tape & put it on the inside of the cover in the area opposite the battery. Its just enough to dampen the resonance & improved call quality to everyone so far. All this after setting everything to evrc-b too.

I'm so glad I'm not the only one having this problem. I've been fighting with Verizon over this issue since I bought the phone. They think I'm crazy and wouldn't give me a replacement of a different brand. They've replaced the phone 3 times now even though I told them it isn't defective, and it's more of a design flaw of the phone.

I will be giving this a try. During many of my calls people say where are you at, just be cause it is crazy loud on there side. The only plus side, my wife never calls to talk to me anymore during the day.

Nexus 6p microphone

I noticed when i talk on my phone and place the phone on my desk on its back, people say they can't hear me... Is there only one mic on the nexus 6p which is on the back ?
Getting the same whenever I hunch my shoulder up to balance the phone near my cheek

I think I had a similar issue with my Nexus 5. When the noise cancellation mic was blocked, people would have a hard time hearing me. My guess is now that the mic is on the back and not the top it is easier to block.
The Nexus 6P is supposed to have three microphones. I assume the main mic is in the bottom speaker. There is clearly a mic hole on the back just below the camera hump, so that may be what people are blocking. I'm not sure where the third mic is, perhaps in the top speaker.
It is a little odd that block one of the extra noise cancellation mics on the back of a phone would disrupt call quality (at least in a quiet place). This is a common design and you'd think the obvious use case of speakerphone with the phone sitting on a flat surface would be considered.
Perhaps, once one of the noise cancellation mics is blocked, the phone can't tell what's background noise and what's your voice, so it starts attenuating your voice as if it's background noise?
I'm assuming the 6P using Qualcomm's Fluence noise cancellation, which is what most phones with Qualcomm chipsets use these days. Fluence has always been kind of mediocre as far as noice cancellation goes. The Nexus 5 with Fluence tended to cut people's voice off a lot. I was hoping the extra third microphone would improve things, but it's also the algorithm that matters.
There's definitely better noise cancellation out there. The Audience chip (now called EarSmart) is probably the best. It was in the Nexus One, which had amazing noise cancellation (and also in the iPhone 4). But both Apple and Google dropped it. Samsung put it in a lot of the Galaxy S phones, but has dropped it now too. I assume they just don't want to pay for the licensing. Motorola uses four microphone noise cancellation and their own propriety algorithm, which is pretty good--that's what's in the Moto X 2014 and the Nexus 6, don't know about the new Moto X.
Anyway, you could experiment with covering the hole on the back and see if that's what's causing the problem.
I facing the same issue. Not sure hardware issue or software issue or some setting.
Having the same issue, need to have the microphone right up to my mouth for anyone to hear me. If I move it an inch away people sound it too low. Going to get onto google tonight about returning. Hopefully it's just a faulty microphone and not the phone design. I've tested in quite and noisy spots and same in both. Also checking not to cover any pin holes in phone that may be noise cancelling microphones.
I have the same issue with people reporting they cant hear me when the bottom mic is off angle from my mouth. I've done some testing by calling a desk phone on speaker and playing with the angle of the phone. From my testing and personal opinion it seems that the issue is likely due to over aggressive noise cancellation. Hopefully this is fixed in a software update or google gives us at least the ability to disable noise cancelation.
I am having the same issue, complaints that I am not able to be heard.
Any feedback yet on this?
Same issue here, a lot of people saying they cant hear me properly, if i then swivel the phone so the mic is in line with my mouth problem goes away. It seems very sensitive!!
Same here...
Anyone resolve this issue with a replacement device? It's quite annoying to have the phone glued to your face and if you move an inch the other party cant hear you clearly.

Same here....not sure if its a hardware issue or bad design? But if every phone is not like this then I have to send it back. Just need to determine what it is first.
Also when playing music my bottom speaker is not as loud as my top....I'm assuming that is a defect as well.
Same here with 2 devices. I've read that disabling noise cancelling fixes the issue, but this obviously requires root to do. I sure hope Google adds an option to disable this without having to root....or at least tones it down because it definitely does seem over-aggressive.
I also enabled advanced calling on both devices, and I'm not sure that didn't *help* at least a tiny bit...although I don't really have much to base that one other than neither of us getting any complaints for the past 24-48 hours....and if any of you are for sure using advanced calling and still getting complaints than I guess take this fwiw.
I remember this happening with my Nexus 5... The fix was to disable to the noise cancellation until Google came out with a patch.
I was talking to a nice Tech guy from Huawei on a completely separate issue, when I tried to hold my phone with the face while resting it on my shoulder. The guy told me that he started hearing me all muffled up. When I told him what I was doing. He told me that there is a third Mic that is in the back of the phone, which when covered, causes low or muffled noise to the other user. Seems, like disabling noise cancelling is the only option to fix this, because I do want to put my phone down and use speakerphone., especially during long conference calls.. Hope someone else can find a solution that does not require root.
There is a huge post on the official nexus forums about this issue with an actual official (kinda) response here.
It's very obvious at this point that this is a software issue related to noise canceling.
Just commenting to say that I'm experiencing the same thing as everyone else here. Thought it was just because the phone was so big, but looks like its definitely a software issue related to noise canceling
I have same issue got a replacement thought it fixed it, but realized today I still have the same issue. I am losing my patience with this phone and the replacement device has a pink hue on the top of my screen.
It's not a bug, it's already been explained that it's because if you cover the noise cancellation mic on the back near the top you'll muffle yourself. Personally I don;t know how you could possible hold this phone in a manner that would block it but... I'm used to seeing a lot of nonsensical issues from smartphone forum posters these days.
I've had the phone resting face up on the table on speakerphone and the person the other end can't hear me properly

Using shoulder to hold phone on call

Anyone else use their shoulder to hold their phone while on a call? People say they can't hear me and I'm cutting out. This really sucks because I'm usually using both hands when talking on the phone.
That's crazy that you mention that. I've been having the exact same thing happen on my Nexus 6.

I'd assume if you're not holding the phone a certain way, noise cancellation thinks your voice is a background voice and blocks you out. If you're at home or in quieter environments, turning off noise cancellation to fix this shouldn't be much of a problem.

Hell if I know. I've been pending for like 18 days. I just know on my current phone, noise cancellation is very aggressive and gets in the way sometimes. Does the 6P have a setting for noise cancellation?

I vaguely remember having this issue with my N6. It might be related to how stock Android does noise cancellation. I made the switch to a wired headset. So much easier/consistent.
Antenna is up in that glass near the camera. If you grab that part with your hand signal will drop. I imagine if it's pressed your shoulder same thing will happen. Not sure if that is the cause of the issue just something I noticed

Noise cancellation is not a feature of Android, it's part of the electronics of the phone itself.
The 6P probalby uses Qualcomm's Fluence noise cancellation, which is built into Qualcomm's Snapdragon chipsets. Other phones have a separate chip for noise cancellation, like in the Nexus One, which used the Audience chip (now called Earsmart)--Audience is much superior to Fluence, but people are using it less and less (probably to avoid licensing feeds). The Nexus 6 uses Motorola's Crystal Talk (also better than Fluence). In any case, active noise cancellation is a hardware feature and has nothing to do with Android per se. Even Apple once used the Audience chip (in the iPhone 4)--now Apple uses it's own in-house and very much inferior solution (being cheap is universal).
In any case, the 6P has three microphones, two of which are used for noise cancellation. One of them is clearly right below the camera hump, on the back. You can easily see the hole. If you block that hole, you probably can cause problems with how the microphones are supposed to work in conjunction with each other. Given that holding the phone between your shoulder and your ear is going to press your shoulder against and cover up the top of the back of the phone, it seems probable that the microphone below the camera hump is being blocked.
The main mic that you speak into on the 6P is probably in the bottom speaker grill. I can't really figure out where the third mic is. In theory, three microphones, instead of two, should improve noise cancellation, but I haven't see anyone do a good review of this yet on the 6P (reviews pretty much ignore this feature these days, even AnandTech that used to do a nice test on it with new phones and post recordings for people to hear the differences).
The Nexus 6 has four microphones, so it would be even easier, I suppose to block a microphone on that phone and mess things up.
interesting thought. i wonder if there's a difference between "disabling" a mic and "blocking" a mic. if you think about it, your shoulder on the rear mic is probably louder than the one you're talking in to as you are rubbing against it.
Could someone test covering that mic with your finger and reporting the results?

Thanks for the info! I also had a feeling that, at least on the 6P, the mic hole on the back could cause issues if covered.

Yes I'm having the same issue. I'm sure it's the noise cancelling feature because if I adjust the phone upwards then the problem is gone. However, it's not easy to shoulder the phone like that.

You should stop doing that. You will mess up your neck/spine. Get a bluetooth.
Never use bent neck/shoulder. Prefer Speaker phone.

Rattling Speakers!

Been using my phone for a bit over a day now and I noticed that the bottom speaker has a slight rattling noise to it, especially at full blast. It's almost as if the speaker is too loud for its own good. It is really noticeable with higher-pitched tunes, such as the one from the following link:
https://youtu.be/GYtck_85rJQ
Can anyone test this out and confirm?
Volume-wise, they seem to be pretty even. However, as someone who listens to music a lot, I know this is going to drive me crazy.
By the way, this issue is obviously not present when connected to a headphone or via Bluetooth. So its definitely the speaker itself.

My phone has a rattle on the top speaker. I received a new device from Google which had a jaundice yellow screen but no rattle. I sent back the device with the bad screen and will request another RMA for the original device.
I read this & gave mine a good shake. I'm good but I'm glad you posted to look out for it.
Just tested on 2 phones, both seem fine.

I'm pretty sure he means the noise the speaker makes while playing music, not a physical rattle from shaking the device.
Yes. It's more like a buzzing sound when something high pitched is playing. As if the speaker can't handle the loud volume.
Oh I see. Ok I tested the video and mine is fine. The speakers don't sound over driven.

@akarol, what's the manufacturing date of your 6P? To see your manufacturing date, boot into the bootloader and select "Barcode". One of the barcodes should have a date, mine was October 31st. I'm curious to see if the speaker rattle issue is particular to some 6Ps manufactured on certain dates. I'm pretty sure I experienced some slight rattling on my bottom speaker while playing the music rhythm game Deemo. It doesn't really bother me that much though, and it would be too much of a hassle for my parents if I were to RMA the device, especially so soon after I just got it.
Got mine 2 weeks ago from Best Buy Canada, but didn't notice that issue at first. I suspect that this may be amplified by time, or maybe I just didn't pay attention at firt. I did what you said to see the manufacturing date and mine is October 24th. Maybe this is specific to early production devices. I am gonna exchange it in store today and see if the new one is fine.
Can anyone with this issue confirm if the new one is fine or the same?
Thanks.
I think it's present on all devices and those who say aren't there just don't have the ears for it. I'm on my 3rd RMA and it's still there. All 3! I'll probably just keep the original device.

The video you posted doesn't cause it for me. However, the launch screen of clash of clans does. Ah well.
About 3 days ago I started noticing this issue on mine. Mainly, when I was receiving a text, the tone sounded really over-driven for the speaker.
Then I was watching a YouTube video today, and I noticed it a lot. I honestly think it's the speaker itself slightly rattling with high pitched noises.
Kind of disappointed in this. I don't feel like sending it back, but it's sad. Maybe a kernel with a good amount of audio control can solve this. Maybe if I could tune down the highs a bit.
I don't have Nexus Protect or anything, but I know the device is still covered under warranty. Is this something that could easily be claimed under warranty, or probably not?
I honestly think it's a design that flaw. I have it in all 3 of my speakers. All 3 of them it's with the bottom speaker. I don't think RMAing or sending it in would solve anything. Maybe some time after when it's been addressed. I'll learn to live with this knowing that I don't usually keep these things past a year anyways.

My current issue is with the top speaker, instead of the bottom. And my top speaker is getting progressively worse. It's a very annoying buzzing/high pitched static noise that comes with almost any sound. Notifications, alarms, phone ringer, YouTube videos, etc. Its getting worse, and so I submitted an RMA and have a replacement coming out.
Since you say yours is with the bottom, and mine is strictly with the top, it sounds interesting.
Mine is almost bad enough though that you wouldn't want to live with it. I'll try and get a recording of it.
anyone have any updates on this? I just got mine nexus 6p about 2 weeks ago and it's been driving me nuts. The top speaker has a buzzing sound when playing certain videos, songs or notification tones. One specifically is the "Tethys" notification tone that causes the buzzing pretty badly. I have tried viper4android and tried every configuration possible and it still has the buzzing. Has anyone managed to get a device that does not have this issue?
I've got this similar problem too, with my top speaker. Testing my speakers with this video: https://youtu.be/qNf9nzvnd1k?t=54s top one starts buzzing at approximately 250 Hz, even on half of the volume. Bottom speaker is crystal clear (maybe with exception of 100% volume, but I'm ok with this). After reading this thread's posts I'm not sure if I should send it back on warranty, especially that my N6P is free of any other flaws.
Interesting: bootloader barcode screen shows 12-10-2015 - that's quite old unit, considering the fact that I bought it in the middle of January...
Honestly, I went through 3 and they all had some rattling. Over the months, I haven't noticed it anymore. Either I forgot about it, or it actually improved. As long as the volume is even on both, I wouldn't risk getting a worse device.

I have the exact same problem with top speaker buzz, really noticeable with the tethys notification sound and in youtube videos with deeper sounds. I have tried RMA'ing twice, the first one the speakers were perfect but had a screen problem so I sent it back and kept my original, and the second had the exact same speaker problem so I kept the original again. I am very frustrated with this. A question I have though is when I just leave my finger on the left corner of the speaker that buzzes, it stops buzzing. Has anyone tried any home repairs? What if we were to put a drop of super glue in the left corner of the speaker? is that likely to fix the problem? I appreciate the help guys.
