I have been experiencing call quality issues with my X7501. The problem seems to occur when the other person is in a noisy environment like in a noisy car or club. The result sounds like a broken or intermittent connection, where each of us can only hear bits and pieces of our conversation.
This does not seem to occur under any other circumstances so I am wondering if it is related to the Athena's in-built speakerphone. Maybe the microphone and speaker are interacting to cause this?
I am going to experiment with the microphone AGC, try covering the microphone, adjust the volume level, etc. next time this happens to try and track down the cause.
If anyone has experienced similar issues please post here.
Thanks!
Is anyone else having this problem? 65 views and no replies makes me wonder if I have a defective unit. I have determined the following:
1. The microphone AGC has no noticeable effect
2. The voice call is broken and intermittent if either party is in a noisy environment, not just the party being called
3. Covering the microphone with a fingertip restores the conversation to normal
It's almost like the phone is not full duplex...
Update...
I have found out that covering the microphone (like with a fingertip) solves this issue. This works at either end of the conversation, wherever the noise is. Of cource this does not help if calling a conventional handset (ulesss the other party uses the "mute" button...
I am still wondering if onyone else is having this problem? Please let me know.

I have te same effect if not using headset. That is way I mostly use my Jabra stereo headset. Works well in any conditions.
The reason is that the mic is close to left speaker. Solution would be to switch it off, but I haven't heard of anybody done it.
I also use voip, but not the WM6 inbuilt one. I use Aget phone. Normaly it uses only speakerhone, but with stereo headset, incoming audio goes through headset, and my voice is picked up by mic builtin the Athena. It works well.
i do get the same problem if the person i am speaking to is in a noisy environment.
I have just got into the habit of holding the phone with my finger over the left speaker since i noticed it and it seems to be fine now.
A niggly little thing really, but not a deal beaker in my opinion. Such is the life of the gadget freak.......!
I was wondering if anyone had found a way to lower the volume on the speaker phone so that you could use it as the ear piece instead of the one on the front? I am wondering because I hate getting the screen all dirty when I use the regular ear piece and I thought since the mic is on the bottom you could just use the speaker on the back and not mess up the screen. However, when I have tried this the sound is way too loud to have next to my ear. I have searched for a way to lower this volume to a decent level, but found nothing. The other hard part is that I also want to be able to turn the speaker back up when I want to use it as a real speaker phone so I don't want to just lower the overall volume through the speaker. Does anyone know of a way to get more range out of the speaker volume so I can do this? Are there any hacks, tips, or programs that will do this? Any help would be much appreciated!

Using NueAudio, you can configure each part, speaker included. I am sure you can lower the speaker to almost nothing and it should work as a regular earpiece.
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?

It's the other party not being able to hear when on aux.
Misread.. But Yea if using speakerphone to avoid this problem ull barely be able to hear them, simply not loud enough
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?
Anyone else have the problem of very low microphone volume when using a headset on this phone?
I've tried multiple headsets, including the one it comes with and everyone describes me as "far away from the phone", I basically have to put the mic on my lips or inside my mouth to sound "normal".
When I use the same headsets with any other device (tablet, computer, whatever) it sounds just fine and the mic volume is no trouble.
I'm basically asking here since I can't find anything on it online, anyone have the same issue? It's kind of annoying having to take my headset out every time I want to use the phone which means my hands aren't available to do other things whilst talking.
If anyone can shed some light on this I would love it. I'm on the latest update btw but I have had this problem for as long as I can remember.
