nexus 6p echo - Nexus 6P Q&A, Help & Troubleshooting

Guys, this is just annoying. I struggle with the echo, I have already tried everything that is possible: and turned off the noise reduction in build.prop, and changed the values ​​in audio_platform_info.xml, and unscrewed the screws at the bottom.
Turning off the noise during a normal call certainly helps, but you have to forget about all the loud communications and video calls, because there the speaker begins to wildly quack at the interlocutor when I say something.
This problem is already 100 years old. Has nobody really come up with a solution. Talented programmers are sitting here, tell me, is it possible to make the noise switch only on the speakerphone?

EM-ONE constant speaker noise

I recently bought an EM-ONE here in Japan and so far I am quite pleased with the device. It has a few shortcomings, but nothing too serious apart from one bug that is really annoying: When the device is turned on there is constant white and high frequency noise coming from the speaker. Even if I mute them the noise is still there and quite perceptible when the volume is tuned low. This turns out really bad when using the device's microphone as the noice gets recorded as well which puts a lot of static on the line. My question would be if there is anyone else sharing this problem (maybe on another device) and if there is anything I can do about it. Any help will be greatly appreciated!

Microphone low sensitivity when not on speaker

I have noticed an issue that did not exist with the Galaxy Nexus.
When not on speakerphone the microphone sensitivity is down-regulated significantly from the way it is when it is on speakerphone.
Frequently people connect the phone via auxiliary cable in the car (as a hands-free approach), but in order for it to route the audio to the speakers for the car, it cannot be on speakerphone. However when not on speakerphone the sensitivity of the microphone is limited, it is not the same as on speakerphone, therefore unless you have the phone right beside your mouth, the other party will be unable to hear you (due to low volume).
I assume this is an software change in 4.2, I have tested the issue on two Nexus 4's. When turning back on speakerphone, the microphone increases sensitivity again, and the other party is able to hear clearly again.
This poses a problem if you want to have the phone in your car connected to auxiliary and not right beside your mouth/face. I assume they added this because they assume that if the phone was not on speakerphone then it would be right beside your mouth/face during a call, however this is not at all always the case, especially if you connect your phone via aux in the car.
Anybody else experienced this? Any work-around?
Yes, thats really a shame.
I think, it is the noise cancellation. Nexus One has Niose Cancellation, too.
There I've found out, that I have to make a change in the build.prop to disable this
but I really don't know, where to find the line in build.prop to disable the noise cancellation.
And: You have to root your phone to do this.
It's really a shame, I can't use my Nexus 4 in my car plugged into the auxiliary input
hmm anyone can disable it via build.prop?
reminds me a of the days in Nexus one..
I've opened an issue on Google.
Hoping for many votes, that they can see it.

Thank you so much for bringing this up. This is my main beef with the phone coming from my Gnex. Hopefully a fix can be found soon.:good:
My suspicion is that this has to do with noise cancellation. The way noise cancellation works is that there are two different microphones at opposite ends of the phone; the one farther away from your mouth picks up ambient sounds and, more faintly, your voice. The one nearer your mouth picks up ambient sounds and, more loudly, your voice. What gets sent over the phone connection is, effectively, the difference between the signals from the two microphones, leaving mostly your voice.
If the two microphones are roughly equal distances from your mouth, they both pick up your voice about equally strongly, meaning that your voice is mostly filtered out with the rest of the ambient noise. Speakerphone mode disables the noise cancellation, so your voice comes through strongly.
.... as I've said in the second post. Other phones don't have trouble with it.

Exactly. This is not simply a noise cancellation problem IMO. Other phones have noise cancellation too but don't have this problem.

Sorry for inadvertently repeating what you said in that post; it's been nearly two weeks since then, and I had forgotten it had been previously mentioned.
Perhaps the other phones with noise cancellation that don't exhibit this behavior simply turn it off if a headphone is plugged in. That would make sense for a speaker-only headphone, but not necessarily for a headphone with an inline microphone, where the voice microphone would still be nearer to you than the auxiliary microphone. If that's the case, it would be nice if that setting were exposed as a controllable option.
Please look here and add as many stars, as you all can:
http://code.google.com/p/android/is... 4&colspec=ID Type Status Owner Summary Stars
I'm the only one who has told it to google and with one star I think no one will see this problem there.
So we have to gewt as many stars and comments as possible.
Any developers can help with the build.prop line to disable this?
I remember pm founder of cyanogen mod and he pointed me the line to disable in nexus one..
I heard if you get an external mic it is much better but I haven't tried myself. This is annoying because I usually just use the aux with my nexus s with no problems >.< Anyone out there got any other solutions?
Yea seriously bump on this topic. This is a massive problem..
Have you all voted on Google page for this problem?

N9005 - Mic volume too low while on speaker phone

Hi guys,
Recently bought a Note 3 N9005 and just wanted to confirm if anyone else is experiencing problems with people listening to you while on speakerphone.
I realised after a few days of use that many people are complaining on the other end of the call quality. I sound too low and far away. When I switch off speakerphone the call quality changes drastically on the other end. One person compared the difference as going from a 10 to a 2 when switching to speakerphone.
This has to be a software problem as when I turn speakerphone off and hold the phone away from me the person on the other end says I still sound loud enough. This points to maybe the volume level for the mic is set too low, but I could be wrong and it may be just my phone.
I'm coming from a Note 1 which has excellent call quality on either end with speaker phone. Because of the size of these phones I tend to use speakerphone a lot and very reliant on it. I also noticed at max volume there's a bit of a vibrating sound during volume peaks on speakerphone also, but that is not an issue as it's plenty loud at one notch lower.

Build number: XXUBMI7
Your experiences are appreciated guys.
Mine is fine. Is your volume at full or thw speaker is not blocked

On my end it's fine. It's the other end that has trouble listening, which leads me to believe the mic on the Note 3 during speaker calls is not set high enough.
I think i've worked it out. This only appears to happen on calls with another person who's phone is also compatible with HD Voice. This did not happen with a normal voice call today. The other end could hear me just fine.
This could be crap if it really is only happening with HD Voice calls as more and more phones are becoming compatible with it. Hopefully it can be fixed with software if it's the case.
Thanks for weighing in though Baste07, appreciate it.
Just go to settings, sound, call, uncheck noise reduction option. Now you can talk 5m away from your phone with crystal clear voice
Solved
So I followed the instructions here regarding the sound noise reduction thing and worked as planned, after done everything possible, including factory reset and opening and cleaning the hardware, I had a hitch that wasn't hardware, so yes it was the new system. If your phone loudspeaker microphone isn't working is because the noise reduction feature inside settings. Look up there and remove it.

[Q] Earpiece distortion

HI there guys.
Brand new to this forum.
I've searched for days and I'm unable to find a solution.
I'm experiencing a crackling or a distortion on phone calls at certain volumes. I noticed it with certain pitches in peoples voices it would cause a vibration in the ear speaker and some distortion in the sound. Kind of like the speaker is being over driven or has too much power going to it. It usually goes away if I turn the volume almost all the way down, but this is obviously not a practical option since I'm not always making phone calls in a dead silent room. The speaker phone works fine. This only happens when I'm using the earpiece. Is this normal? Is it related to the camera autofocus sensor rattle? Are the sound vibrations from a person's voice enough to set off the rattle? It's really annoying as I tend to make phone calls a lot and I don't like using speaker phone or a headset. Does anyone else have this problem?
From what I can tell, it happened and was normal in the S4. (http://forum.xda-developers.com/showthread.php?t=2280930).
Please help. Im deciding if i need to return it.

It's too bad that you didn't describe it in more detail.. i.e. give us steps to replicate it. A recording of the distortion would have been helpful too. I haven't noticed what you describe but it sounds like the gain or auto gain is too high and your earpiece speaker is being overdriven.
There is a gain setting in the service mode menu but first you need to distinguish an app issue or possibly damaged speaker before messing around in the hidden settings. See if you can find an audio app that will give you a wider adjustment range for your system volume and gain.,

Thank you for the reply.
If you go into the service menu, the go into the low frequency test. At 100hz and 200 hz there is a little bit of buzz in the headset reciever unless you really push it against your face (which i assume kind of tightens the spaces in the plastic and prevents whatever vibration in the speaker is occuring).
Hmm.. the vibration is akin to as if you were speaking into some cellophane wrap; like some film (maybe for waterproofing) is covering the speaker.
Oh. It's also worth noting that I cannot replicate the issue on Skype or Viber. Those sound crystal clear.
Bump. Anyone?

Odd hissing and generally annoying noises while using headset with Mic on phone call

Ok..maybe I just got a bad unit. But here it is. Phone is one day old.
When I initiate a phone call with my wired headset, I immediately get hissing. Then if I move my head or the wire brushes my cheek.. it sounds like someone is making sexy time with a paper sack inside my head. This isn't an echo as it is real-time. All the noise is obviously being picked up by the mic and is pumped into my ears at an explosive level. I attempted to turn the volume down which only resulted in the call volume dropping rather than the demonic feedback. It kind of reminds me of the in-ear monitors that vocalists would use.
Here's what I've tried:
1) 6 different headsets, all different brands and cost including the freebies that came with the phone. The only set that didn't blow my eardrums out with noise were some cheap ass Maxwells from Wal-Mart, but the problem was still there
2) looked through all the settings I could find. The only thing that makes a difference is turning on TTY mode.. which causes too low a volume for me to carry a conversation without going into a noise cancelling chamber.
3) applied the latest OTA update. No change
What I'm willing to try:
1) rooting and flashing a new rom.. But only if this will actually fix my issue.
2) perform a sacrificial ritual involving an SII, an SIII, and an S4... None of which had this issue.
3) changing some call setting that is hidden somewhere between Narnia and Atlantis....
Thanks in advance
Quick update....
Tried the demo unit at retail store.. same thing.
Tried bluetooth headset.. no problem.
It seems like as soon as the Phone app opens a connection the mic is overamplified or SOMETHING. It is driving me nuts and I hate my BT headset.
Still wanting to know if anyone else is experiencing this.
Just a quick update.. This is still present even with BT headset. For a lack of better phrasing.. this seems like the mic is being back-fed into the ear pieces. And it only happens on the Phone app. It there a setting somewhere that I am missing that will solve this? It is super annoying to be able to hear yourself and surrounding noises than the person you are trying to talk to.
Thanks
Tried mucking around in mixer_gains.xml to no avail. Maybe some kind soul who is smarter than I am could provide some guidance? I don't know how to explain it any better.. It's as if everything going into the mic is being output simultaneously to the buds. It drives me nuts
I just tried to listen to what you were describing on my headsets/headphones but I couldn't replicate it. Crystal clear calls for me, and apart from it being the headsets I have no idea. Maybe both you and the store have faulty units.
