Poor sound quality in phonecalls on N5

@advocatux said in Poor sound quality in phonecalls on N5:
@wgarcia the reason I asked is because if the device giving you troubles is a D820, that would explain them.
D820 has known in-call sound quality problems? Maybe I shouldn't move my UT testing from OpO to N5 after all. Still haven't plugged in a live SIM, so haven't tested voice firsthand yet.

@trainailleur D820 is set up to work with North America frequency bands, D821 is set up to work in the rest of the world. That could be the reason in this specific case (user in Europe)

Oh, okay, that's a relief.
(The signal quality I get with the OpO is abysmal under Android, hence my motivation to switch.)I could easily be mistaken, but I believe 2G and 3G connectivity is identical between the two, save for an additional UMTS band in the D820. LTE bands do differ (with poor overlap), and of course the D820 has CDMA also, which the D821 does not (though I have no idea if UT can use CDMA, and it seems uncommon in Europe anyway).

Mine is a D821. People that i call complain that they don't listen well.
I tested with my other phone:
If i'm close to the speaker it works. Moving the speaker away (~20cm) gives a very poor sound quality. With the tested Samsung 50cm are no problem.
That's why the handsfree function does not really work. (i tried to use it while driving, but it never worked, so i had to stop to make the phonecall ;-))
Would be great if someone with android could test. -
@htc_tattoo Nexus 5 little holes for the speaker & mic are prone to keep dirt in them. After cleaning them by gently brushing with a soft toothbrush, the difference in quality and volume was pretty notable in my case (YMMV).
-
@advocatux I already checked, i can see inside. Did you try to talk over the speaker with the phone an armlenth away? Does it work in your phone? Mine gets totally ununderstandable...i will check with an android version.
-
@htc_tattoo yes, it works at arm's length for me
-
@advocatux I checked with an audio recorder (guitar tools), works perfectly up to some meters. So it's something connected with phonecalls.
-
@htc_tattoo no idea then, sorry
-
@htc_tattoo on second thought, maybe you can fine tune / improve the phone sound with https://open-store.io/app/uvolman.mateosalta?
-
@advocatux Thanks, but it didn't change. I tried all the settings, it changes with a audio recorder, but does not change anything while phonecalls.
Testsetup: call another phone close to you, turn off the other phones micro and listen to your speach. If you speak directly to the spaeker it's fine, if you turn the speaker a little bit away it gets disturbed.
Seems that phonecalls use the microphone differently than multimedia apps.I think i will write a bugreport as this is one of the core functions of a phone.
-
@advocatux I finally remembered to check the model of my second Nexus 5, the one where sound volume is very low in phone calls, and where cell network signal very often is hard to maintain. I confirm that is is a D820, so that explains it, since I'm located in Europe.
-
This low volume in calls seems to have been also a problem since the release of Nexus 5:

@wgarcia that was a hardware problem in the first N5 batch but that glue problem was fixed, and there were some firmware updates too since then.
-
Did you try to mute and unmute at the beginning of the call?
The symptoms that you describe sound quite familiar. There is a bug with the microphone in the phone app which starts it kind of muted. Thus it works but poorly. Then after muting and unmuting the sound is normal.Edit: And of course I have exactly this problem too.
