phone call audio problem with ameo

I don't know if this is a fault or something I didn't expect but would be glad to here how others have found it.
I have had the ameo for a few weeks and have noticed that if I use a bluetooth or wired headphone everything seems to be fine on a phone call. However when I try to use it as a speakerphone, whoever I am speaking to complains that my voice is breaking up (I have a strong signal strength). It appears that if there is any response from the person I call or any noise in their background then the microphone at my end is interrupted making my voice unintelligible. I know the manual says to use a headset but what is the point of having a speakerphone if you can't use it? Does anyone else have the same problem or have I got a faulty unit?

I get this on full volume in a small room. Turning the volume down a bit usually seems to solve it. I think the mic is pretty sensitive and can get flooded a bit too easily.

I have used both the Ameo and the Dopod rom on the same device and can conirm that this problem is worse on the Ameo rom
Could other dopod users tell their experiences regarding hands-free calling

I experienced something similar but only when the caller has a lot of background noise on their end. It's not a consistent problem here so I assume it's not the same issue you're having.

Thanks for the replies - it looks as if the unit is working to spec but that there is a 'built-in' problem when using the phone as a speakerphone. I didn't get this on the spv2000 I replaced with the ameo so wasn't expecting it. Background noise does seem to trigger it - I just tried phoning using the speaker phone to call an answerphone and it worked fine with clear audio at the other end. I think a day or 2 of playing with the volume to minimise the problem is the next step. I'll post back when I can be more definite but would be grateful for any other opinions.
Cheers

On my U1000 the mic works fine in speakerphone mode. There are no brakeups of voice even while walking mid-traffic. Yes, I have to speak loud but that is expected with background noise over 85db.
However, the speakers do not return sound very loud at all (for a speakerphone). I have to lean way forward and almost put my face on the screen to be able to clearly hear the other side (even in a totally quiet environment).
Would have been great to have had a decent speaker phone, but as it is I'm sticking to my bluetooth headset.
The 2 drawbacks with bluetooth is the answer delay, it takes a good 1 second before the connection is established between the headset and phone. The second thing is the sensitivity of the mic, it picks up everything that goes on around you, and drowns out your voice. I have to move the mic close to my mouth if there is other noises going on around me (but this is most likely a bluetooth headset problem, and not related to the U1000).

OK several calls later and after fiddling about with the volume I've found that the best way for this problem to be overcome is to set the 'in call' volume to its lowest! I've also set the main unit volume to about 40% but that shouldn't really have any effect. It's odd that the best way for the speakerphone to work is on minimum volume - fine for single calls but not much use if I want a few other people to listen in. However this is a very small problem now and the benefits of this device hugely outweigh this small drawback.

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?

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

In call microphone issues when using headphones

Does anyone else have the problem where the other person can't hear you when you use a pair of headphones while in a call? When removed, they can hear me fine. I'm hoping that this is a software issue that can be resolved in an update. If not, then i want to return it before my remorse period is over.

I am having distorted sound - other party hearing it unclear and distorted..
looks like a hardware issue.. tried with 2 earpiece... no luck.

I'm actually starting to wonder about that. It may actually be a software/driver issue. I was on the phone yesterday and decided to do some testing. Unplugging them and plugging them back in provides perfect audio to the other person for a few seconds before going back to garbage, as does muting and then un-muting the microphone when in a call. Something I've noticed about the microphone is that the gain seems to be set too high - try to make a recording of cars going by - guaranteed clipping (don't have the volume too loud or you could blow out the speaker you're listening to it on).

I ran into the same issue. However, the headphones I was using didn't have a built in microphone. I discovered that if I plug in headphones that lacked a built-in mic, the phone switches its internal microphone's gain to the gain it would use if you were holding the headset to your ear. I held the microphone in close proximity to my mouth and that solved the issue.
I guess this would be a software issue.

That's exactly the testing I did and exactly what I was thinking. Now to wait for LG or Google to fix it.

Another experiment you might try would be to put your finger over the secondary microphone on top of the phone and see if that makes a difference. (My guess is that the reason your voice comes through softly with the headphone plugged in is that the phone is still doing background noise suppression, which works by taking the difference between the main microphone, which picks up your voice plus ambient noise, and the secondary microphone, which mostly picks up just the ambient noise. When your mouth is far away from the phone, your voice is equally loud in both microphones, so the difference doesn't yield much voice signal. If your voice comes through louder after stopping up the secondary microphone, that would confirm this explanation for the problem.)

Next time I'm in a long phone call where I am using headphones, I'm going to try that. It could be possible.

This appears to be what is happening. The top mic is doing noise cancelation for the bottom mic.
I called a friend and plugged in headphones. When I didn't cover either mic, she said I was quiet (because the phone thought I was background noise). When I covered the top mic, she could hear me fine.
At this point, I'm inclined to say this is a software issue because the phone app can switch between microphones and which one is used for background noise cancelation. (Putting the device in speaker mode appears to use the top mic only.)

That's good confirmation -- thanks for running the experiment. Maybe I'll put a little wad of putty in the car to stick over the top microphone while I'm driving!

[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?

Poor call quality (both over cellular network and WiFi)

Hey fellas,
So the call quality on my g4+ absolutely sucks. It doesn't matter if I am using the cellular network (for voice calls) or WiFi (Skype, Duo etc.). People always complain that either there is a lot of static or as if I am talking from an extremely windy location (No I'm not actually in a windy location). And the funny thing is that the problems are the same on both networks, which leads me to believe that it could be a local problem. Maybe something with the microphone or the voice cancellation or perhapps the radio on the device ? Listeners also complain that my microphone is too silent. For video calls, I literally have to put my mouth next to the mic for the other side to listen to me properly.
I have tested my WiFi connection by placing same calls on Skype using G4 plus and my G1 one after another. Not a speck of noise in the G1.
Now I bought this device in India and am currently in Germany which makes approaching customer service a bit tricky.
Has anyone had problems like this? Any suggestions or fixes? BTW, running a stock device with no custom changes whatsoever.

I wouldn't say for sure but maybe it's cause the in-call audio and loudspeaker both use the same speaker.
Or something to do with your network provider? Perhaps?
But like I said, I am not sure if this might be a reason for poor call quality.
from Moto™ G⁴ Plus (XT1643) running BeanStalk 6 ROM

I am leaning on striking off network issues as the same SIM and WiFi result in clear voice on my 1st gen G. I just went through resetting network settings first and the whole device finally, but to no use.
Can anyone share how their mic works during a video call. Is it loud enough from around 15cm distance for the other side to hear them properly? Just want to make sure that it's not a general device problem.

OK, so I have isolated the problem to be (mostly) in phone's mic or its noise cancellation. I say this because when I use a headset mic, the world is noise-free again.
Does anyone have an idea if noise cancellation works when using the headset mic? If yes, then I guess the only solution to my problem would be to get the mic replaced.

Do you use a body cover?because some covers can also cover the noise reduction hole.

I do yes. But I have checked that already. Removing the back cover doesn't help
I tried recording video and audio today as well. Its a lot more noise/static than my voice. And given that no one else is experiencing this, I am beginning to believe that it is a mic issue with my device.
