[Q] [REQ] Clarification on noise cancellation/possible mod - Samsung Epic 4G Touch

I've heard and read a couple of reports and reviews stating that the ET4G doesn't do noise cancellation unlike the international SGS2...firstly, I was looking for some confirmation from the users here that that's true...
I ask this because, well, there's two mic's in the ET4G (the 2nd one is up near the earpiece, and the hole it uses is actually the right side of your earpiece grill)
I'm guessing what they did, assuming there is indeed NO noise canellation, is use the 2nd mic for speakerphone mode, exactly like the OG Epic (which is a little known fact; the OG Epic also has a 2nd mic up in the earpiece).
So, if that's the case, I'm hoping it's possible to hack together a noise cancellation mod, possibly borrowing from the SGS2's code?

[Q]Voice Quality without Noise Cancelling

As I was looking at the specs of the G2, I noticed that it does NOT have noise cancelling. When I first got my Nexus, people I called couldn't tell I was outdoors speaking to them.
Has anyone gotten comments regarding background noise from someone on the other end of a conversation?
I had hoped that noise cancelling would be a standard feature after being implemented in the N1.
Any thoughts and experiences would be great as I consider upgrading to the G2.
I'm pretty sure the mic is noise cancelling... from what I can tell. The quality of calls is on par with the MTS which had voice cancelling for sure.
Very good voice quality
Not sure since it doesn't specifically say, but I am getting very good voice quality with my G2. Callers also have confirmed their end is quite clear. Love it.
I thought to have noise canceling u had to have 2 mics? Idk not to knowledgeable on that hardware so correct me if I'm wrong but any N1 owners I've talked to on the phone sound crystal clear =)

It would be hard to converse with an MTS user if the mic was indeed voice cancelling. That's weird.

Yes. One microphone is placed away from your mouth and tells the phone what sound to drop.
I'm quite sure it cancels noise. I have the 3.5mm jack plugged into the aux in my Nissan Armada and have asked if the caller hears an echo or other noises and they say "No, it sounds like you are on a phone in a quiet room"

Speakerphone quality?

My wife owns an epic 4g and on speaker during a call, its like the Mic doesn't pick up well. I can set my Evo across the room on speaker and talk w the other person hearing me. Seems like 3 feet Max on the epic. Maybe w bought a Monday phone? Anyone use the et4 for speaker during a call? If so did you have an epic before and is this et4 better?
Used it in my car today on speaker and it seemed to pickup well, probably better than my last phone (HTC Hero). Neither of us were shouting or going "what?" every other sentence, but this was fairly short-range, haven't tried it from across the room or anything yet.
I just came from a Hero. I'm not sure if the speaker phone is as good. I had a call, put my friend on "speaker phone", and one of the first things he said was, "Where are you? There's an echo. I say something and a second later I hear it through your phone." I never had that issue with the Hero.
Cheers
Don't know about the mic but the speakerphone sounds a little muffled and distorts at high volume. I would say it is one notch below the Evo 4g.
Must be Samsung. They make such nice camera parts for the phones, speakerphone side could be improved. Wonder if the nexus s has this issue too

Does the nexus have active noise cancellation?

It has a secondary mic so just wondering if thats only for recording video or if it is also used for noise cancellation
It is used for noise cancellation as well, much like the secondary mic on the nexus one.

Is there a way to confirm this? The getting started guide doesn't say that it can be used for noise cancellation during calls. But it doesn't say it can't do this either.

Sure. Make a couple of test calls in a noisy environment, then stuff a wad of chewing gum into the secondary mike and make more test calls. Ask the person at the other end if they can hear a difference.
Most basic Android phones have this feature and I have no reason to think the GNEX wouldn't.
It never seems to do much good so its no big deal to me.

Think about it...so much noise will seep in between your ear and the phone that it wouldn't make any difference.
Just get a nice pair of IEMs or a noise cancelling headset like the Audio Technica ATH-ANC7b (or their less expensive ANC products).

Lots of ANC headsets have the mic in an in-line power box on the cable. Bose come to mind for a start. So I don't see as it would be impossible to make the phone perform the ANC when using a standard headset.

Having the mic in an in-line box is very different from having the mic on the playback device. An in-line box is a small device that is most likely close to the earpieces and exposed to the same environment as the earpieces. The playback device is much larger, likely to be further away from the earpieces, and rarely exposed to the same environment, as they are more likely to be in pockets, purses, etc.

Well obviously it would have to not be in a pocket. Not that it really matters since it doesn't do it anyway.

When you are playing music, how often do you not have the phone in a pocket or purse or something like that? You will need an armband or belt holster. Having a feature that only works with certain kinds of holsters that most people don't have is a waste.

Wow. Totally different from my experience with GS2 and iPhone and BB.
I was standing right next to my neighbor's pressure cleaner as he was cleaning his roof the other day and my pops could not hear the engine at all while on the phone with me. I was amazed.
Maybe you are talking about older phones?

So does the phone have dedicated mic for Noise cancellation or not? in the top back of the phone there a tiny hole is this the second mic for noise cancellation?
, currently i have the phone but there is no option mentioning noise cancellation anywhere

Yes, it does. I've tested mine sitting next to my teams flight simulator which derives it's computing power from about 24 6foot double sided racks of servers...so it sounds like a hurricane of fans in that room and I've made calls there and people can't hear anything in the background just silence. When I had my 3gs iphone everyone said they couldn't hear anything but fans when i called them.
I don't know. I was just testing the Galaxy Nexus in a Verizon store and I was disappointed by the noise cancellation (compared to my Nexus One). I tested the two phones in the store with a lot of people talking and making noise in the background, by leaving myself voicemail messages.
With the Galaxy Nexus it was silent when I wasn't talking, but when I was talking you could hear the chatter of people in the background. This to me is typical of older phones that did not have a secondary mic to filter out background noise. Instead they just turned the mic off to cancel background noise when you weren't talking.
With the Nexus One, you couldn't hear any background noise at all, whether I was talking or not. The secondary mic lets the noise cancellation chip tell what's your voice and what's background noise and filter out the background, even when you are talking. This has been my consistent experience with the Nexus One and people always comment on how good it is.
I tested two different Galaxy Nexus phones in the Verizon store with the same results (the floor model and a handset belonging to one of the representatives in the store). It did not compare to the quality of the Nexus One. Also the Motorola Razr was much better too (Motorola has always put an emphasis on in-call audio quality that other manufacturer's ignore).
Really, given the results I got, the Galaxy Nexus to me seemed like it did not have proper noise cancellation at all.
It looks like the Galaxy Nexus does not have the Audience chip that's found in the Nexus One, which does the noise cancellation processing:
www.audience.com/products/overview.php
It's strange, because the Audience chip is in many of Samsung's Galaxy S and SII devices. Perhaps the Galaxy Nexus is using some inferior noise cancellation technology. I don't know. But, sadly, in my tests it didn't compare to the Nexus One.
[Edit: This review at PhoneArena claims they experienced the noise cancellation working on an HSPA+ version: www.phonearena.com/reviews/Samsung-Galaxy-Nexus-Review_id2915/page/4. I suppose it's possible that Verizon left the feature out? Or perhaps the store I was in was not loud enough to trigger the noise cancellation, since they describe the noise cancellation as "kicking in" in noisy environments. My impression on the Nexus One is that it is always operating and does not "kick in" at certain points. In any case, the experience on the Verizon Galaxy Nexus is still that I heard the background chatter of other people cutting in and out, as the microphone seemed to switch on and off depending on whether I was talking, which created an annoying effect, not experienced on the Nexus One.]
i got same problem too,try to call to GS2 and defy in the same area, G nexus noise cancellation very poor. hope they will release some kind of patch to fix it
On my Droid X the noise cancellation mic works great, *especially* for concerts, but you have to change the setting on the camera to "Concert." I see no setting in the GN's video camera options so if it does have noise cancellation it's probably not that great.
I wonder if there is an aftermarket camera that will utilize it a bit better.
Whoa, that's soo cool. How did I just discover this?

Moto Hint

Who is planning to get a Moto Hint? I am curious how the experience of having bot ha Moto 360 and the Moto Hint will be. I wonder if the two devices will compete for your words or if they will have a synergy making having both worthwhile. I do a lot of talking on the phone so a nice bluetooth headset really interests me.
the only thing i'm worried about with the hint is that it will really look like you're talking to yourself
Oh dang I actually haven't heard about these but I think they look like they'll be a pretty good product for those who use such devices. I would splurge but I don't think I would actually use it very often...
I was curious and found the Moto Hint last night at Best Buy. It fit great in the ear and was really comfortable. I could hear callers clearly. Issue is that callers could not hear me well. I was told that every few words were clear then there would be a gap of silence while I continued to speak. I tried with the Note 3 and iPhone 5 and both had the same results. I then covered the sensor making the Hint believe it was in my ear and spoke directly into the mic about an inch from my mouth. Callers heard everything I said clearly. It appears that the BT mic is too far from the mouth to pick up speech properly. I had high hopes for the Hint and am disapointed that it didn't operate as advertised. Will give it the benifit of the doubt and swap it out for another one before giving up.
Make sure the two microphones are aligned and pointed toward your mouth and not your eyes. You may have to consciously rotate the back of the unit upwards slightly when you put it in the ear so microphones line up such that they point to your mouth. Found this in user guide and it works great with this slight adjustment in ear.
where do you live? i cant seem to find the moto hint on bestbuys website. Looking at motorola website doesn't seem like they are on sale yet T^T i wanna try this headset out pretty bad lol

I also don't see it on the Best Buy website or Amazon. I found it at the Best Buy in Alexandria, VA. I decided to try another unit since the first was so bad. The Best Buy at the Pentagon City location had five in stock. This one is much better. Tried it last night and the person on the other end of the call could hear and understand everyword I said. Not so good this morning so I will follow gadgetg's instructions. I really like the look and feel of the Hint. Will try it for a few more days before I make the decision to keep it or not. My Plantronics Voyager Edge works great, but definitely not as attractive and discreet as the Hint.
Lucky! Keep us updated!
I Def like the way it looks! I would use it at work most considering i mostly use only one eat with my current setup

Got the Hint yesterday at my local best buy in Miami and I really want to like it but I'm still on the fence. Calls are nice and loud with no issues with being heard. My issue is with streaming audio and how quiet it is compared to the call volume. I have the call volume at the lowest setting it's so loud but the streaming has to be over 3/4's just to be able to hear it. It also sounds a but tinny but I imagine the tiny speaker is doing its best. I turned off the Moto voice always listening feature since I'm using it with a iphone 6+ and I imagine that will also help a bit with battery life. If anyone has any suggested settings to improve streaming volume or battery life please chime in. I got the best buy 2 year insurance for $20 so I can always trade this one in if they ever come out with a different hardware version later on.
My wife really wants the Gear S when it launches and thought the hint would be the perfect accessory for it. Just worried she will lose it!

Yes you can. I'm using it with an iPhone 6 plus and it works great. The only limitation is you can't use moto voice. I have to press the mdf to call Siri.

Thanks for info. I read some review say the stream sound like music is low and difficult to hear, how about yours? And any problem when talk, need to adjust you head or just feel free to talk in air?

I see. Maybe need report back to moto.
I posted this on the Motorola Forums, but those of you with a Hint or thinking of getting one may find it useful
A US friend recently bought me a 2nd gen Moto Hint on his visit to the UK and I've got to say that the microphone
performance is really erratic. I did loads of testing and searching on the internet in case the problems were:
a) Related to the Nexus 5 I was using
b) Related to a faulty unit
c) Related to me not using the correct "gel" or positioning it in my ear correctly.
After a LOT of digging and reading the few reviews out there, I found that in quite a high proportion of the reviews I did eventually find, people mentioned about how others heard them; that people speaking into the Hint came across as quite faint and distant - exactly the problems I was getting.
A bit more digging and testing later, and I managed to eliminate both a) & b) from the equation... using a really crude test
involving a Bluetooth recorder app, I uncovered the following (Hope this helps!):
Option1.
Believe it or not, I can get consistent clear audio recorded - and subsequently call quality where others can hear me
very clearly if I... Take the Hint out of my ear and BLOW HARD into the front mic before quickly putting it back on!! I know it sounds crazy, but every time I do this, the Hint's mic works flawlessly for me (I should add, there is no debris or or anything else blocking the hole to actually be cleared and my ears are clean )
And this trick works whatever the orientation of the Hint in your ear is.. it can be positioned so the mic is level with your eyes, pointing a bit further down towards your mouth, whatever... this to me, completely dispells any previous info about rotational position in your ear being critical to mic's pick up (no consumer device suitable for everyday use should be that sensitive to position IMHO)
FYI, an audio engineer friend of mine thinks the sudden burst of white noise caused by blowing into the mic, might re-set the noise cancelling audio sampling start up processes but without pulling the thing apart and reverse engineering its code, they're at a complete loss to comprehensively explain why this should work..
FYI 2, The same audio engineer friend thinks the noise cancelling algorithms are broken in some way which is the root cause of the mic pick up being so poor out of the box, and could be fixed with a software update. They've got an older Moto Elite Sliver with Mics positioned no closer to the mouth than the Hint and the mic audio quality in comparison is damned good without having to resort to tricks..
Option 2. A bit more fiddly but also do-able, is to hold your hand up around your ear "Secret Service Agent/FBI Agent" style. Don't actually touch the hint, just have a couple of fingers brushing against the top of your ear with your palm and wrist towards your mouth to help channel the audio from your mouth into the Hint's mic. YMMV and in someways, having to do this to get enough audio to the mic kinda defeats the purpose of having such a small Bluetooth earpiece - may as well hold your phone up to your ear instead!
Anyway, I hope my findings help someone who's had problems, might've left it in a drawer etc.

Tinny front speaker?

Good evening all,
I am noticing that my Note 4's front-facing speaker has become tinny during normal conversations while holding to ear.
I read all subject lines in troubleshooting forum without any mention of front speaker problems.
I hold my phone to my head and volume is never maximized.
I can't imagine it's blown, and it hasn't been dropped .
Coming up on my 90-day Costco window for replacement.
Any input welcomed?
Mines using that. It seems to boost the sounds during calls so I'm not complaining
Mine seems top blow my ears out when I use it so it seems adequate.
The best answer world be to try another note 4 and see if it sounds the same.
