Hello,
I've gotten my Z3 in copper last week, and will send it back tomorrow to get a replacement. There are two reasons for that:
1. The display glass is either too small or wasn't put in centered. While I have no gap on the left side, there is a rather one on the right side. Aside from the aesthetic annoyance, it's large enough that it could compromise the IP rating, and I don't want to risk that.
2. Other people complained about call quality, which is what this thread is about.
I tried it with five different partners / phones. Four could hear me most of the time, with one I had to shout. All five said I sound muffled, like I'm talking through a pillow, or as if I wouldn't open my mouth when I speak. Two complained about compression artifacts ("Like an MP3 at 64 kBit/s"). One could make out rather well what I said, two required me to repeat what I say every twenty seconds. All five also said that my voice was very quiet.
Changing from LTE to UMTs and GSM changed nothing.
Turning off noise cancellation in the call settings changed nothing. Setting the mic gain from Auto to High made it not a single bit clearer, but distorted the sound.
Using a headset, everything was okay, though one person said that they still hear a bit of compression artifacts.
The funny thing is that when I used the Sony Recording App to check the mics, they sounded rather good (both of them, you can set it to Stereo and have the lower mic on one and the ambient mic on another channel). So I guess this has something to do with how the codec for telephony works while the microphones are physically okay.
Did anyone else have such problems? I'm waiting for the replacement handset and will check again. It's somewhat annoying, the Z3 is such a nice phone otherwise, but I couldn't use it for calling people.
I noticed that the lower speaker produces a much lower audio than the upper speakers, is normal? Someone told me that is normal because the lower speaker acts like a tweeter for the upper speaker, but I found this not true as the upper speakers has more low, mid and high sounds than the lower spekear, he also told me that this answer was provided by Sony. Can you test this?

Top should be a bit deeper, if you have big difference probably bottom speaker is not ok...
Have you made it wet recently? If one of the speakers ha been exposed to water recently, it has to dry off completely before performing as it should. Another cause might be the accumulation of dirt in the speaker grills, which prevents it from vibrating properly. In the latter case, soak it in water and rinse off.
I have the same problem with mines...seems that the right channel (lower speaker) is in fact significantly softer...causing me to miss a lot of calls since only the right channel speaker is used during incoming call ringtone

So I noticed this morning that my tones only play from the bottom speaker.
I was searching for a ringtone and found one that played nice and loud when I previewed it (from both speakers)... copied it to the ringtone folder, selected it in the sound preferences and when it played it was WAY quieter because it was only playing out of the bottom speaker!!
What gives?
i remember my old sony z3 and z5 did the same, both with front stereo speakers and inly the bottom one played ringtones

This is totally normal. All dual speaker phones do this for both ringtones and speakerphone calls. Once we gain root access, someone needs to find the right line of code in the mixer paths XML file to activate the second speaker.

My HTC One M7 played ringtones, notifications, and speakerphone calls from both speakers and my ZTE Axon 7 plays from both speakers as well. So no, it is not a thing all dual speaker phones do.

My HTC 10 doesnt. Ringtones only from the one speaker
I'm pretty sure it's to idiot proof the phone to prevent people from putting the phone to their ears before actually answering the phone thereby potentially causing damage and a lawsuit due to the significantly louder signal the speakers play when ringing. My iPhone X and Galaxy Note both kinda do the same thing except on the Note 9 some sound does come out of the top speaker unless the proximity sensor detects any nearby objects (like a face) which is the clever way to do it really.

So out of hundreds of phones, the two non standard and ancient phones you can find to back up your opinion is all you've got?
All RELEVANT phones do this. They aren't relevant.

This is the only thing I've found online as well that makes any decent sense. The whole proximity sensor thing sounds great, I wonder why more companies don't do that for all the non-media sounds.

iPhone does use both speakers for ringtones/notifications/alarm. I have iPhone XS, I also had an iPhone X, great sound from both speakers. I don't understand why Google limits the phone like this, not only it only uses the bottom speaker but the sound quality is decreased a lot when comparing the sound coming when it's ringing to playing exactly the same sound with a media player on the phone.

If that's the case then they probably updated it. I sold my iPhone X for a Note 9 and much prefer the sound of the Note 9. The XS is a bit louder but the Note 9 has a much more balanced sound with a pleasant tuning, which is reflected in sound measurements on Notebookcheck from both phones. It also confirms the lower peak volume of the Note 9.
Regarding the Pixel 3 well, I haven't had enough hands on with it to comment but from what I heard the speakers were very powerful albeit with slightly less definition which I guess is the point at the end of the day when you want your phone to be heard... Then again from what you guys are saying it doesn't ring very loud...
Since you have an XS can you confirm whether covering the sensors on the front turns off the top speaker when the phone is ringing?

I have had every iPhone since they implemented dual speakers and the sound for incoming call/notification have always come from both speakers, nothing new at all. That is something that's bothering me a bit when switching to android, you have two speakers why not use em both for ringtones, alarms and so on.
It just seems to lower the volume for both speakers when covering the sensors.

In my opinion I think it is very dangerous to the ears for the top speaker to not turn off with the proximity sensor, as I have been in a situation where I was showing my friend a song I was working on, the phone volume was down low and he was holding the top of the phone near his ear and I got an incoming call. That would have hurt his ear if it was the iPhone. I think it is very clever that Samsung use the proximity sensor to protect our ears from these mistakes. Especially if you're on a call on Facebook then you receive a cellular call through the phone in which case it cancels the Facebook call and rings through the loudspeakers. Again that would be damaging to the ear. Then again I don't Apple has ever really followed hearing protection regulations as they have no volume limit or warning by default on the iPhones with earphones as opposed to Android where you get a message turning it up to high volumes. Again, my Note 9 is plenty loud when it rings in normal situations. I'm not sure about the Pixel 3.

Like I said, it's very low when you're either looking at the screen or covering the sensors. So it's a non issue, can't damage your ear. And to be honest it's not a very common scenario to hold your ear against the earpiece if you're not talking on the phone.

As I mentioned,
I can't speak for the Pixel 3 but the Note 9 rings plenty loud with alarms and calls etc unless the proximity sensor is triggered. It only dims the top speaker tho. I would agree with you about the the ear against the speaker if it wasn't for the all too common scenario of being on a Facebook messenger call with the earpiece then a cellular call comes through, interrupting the messenger call and ringing through the speakers... I do agree with you that the Pixel shouldn't just permantly turn off the top speaker for calls and alarms, that just seems silly. They should utilize the full potential of the speaker system...
2022 Did someone already found a way for dual stereo speaker ringtone for our pixel 3? Google really always loves to mess up.
Can anyone else also hear the rattling noise from camera when keeping the phone down or shaking the phone ?
When dialling someone who is on a carrier with high in call volume/high dial tone volume, I can hear the rattling of camera modules. It is much more when holding the phone to the right ear (camera side down), on the left ear (camera side up), the sound doesnt appear. The carriers which have low dial tone volume such as Jio doesnt have such issues.
Seems that the sound from receiver causes the camera modules to vibrate and make the rattling sound due to high dial tone volume. And because this is the phone with three vertically situated cameras, the sound is much more.
Yes, I confirm about this noise.Because I use a TPU case cover for my phone, this noise can not be made by the button movement. This noise comes from the upper side of the phone
Do you have that noise also when there is loud sound comimg from earpiece ? Everytime when I hold my phone to right ear (camera side is down), I hear that sound and yeah this jiggly ball bearing sound thingy comes from the top of the phone. I checked my earpiece and it plays sound in very good quality. Also the buttons are not faulty because I held them tight and tried shaking the phone, the sound was still there.
@Pr0Ankit - no, sound doesn`t trigger any rattle, only when switching between cameras and if I knock on the phone near the cameras.
I`m too tired to write everything again, so I will copy my posts from gsmarena.
-------
Yes, there is a noise, rattle or whatever word you can use to describe it. It is probably the lens gyro system.
I missed the time to edit my previous post so I`ll write it in this one.
There is a noise/rattle/chattering if you knock the phone and it can be heard from within the cameras zone and I think I know why.
As I`m subscribed to jerryrigeverything on youtube I have seen many teardowns of phones which have gyro optical stabilization on their cameras. He usually give them a poke or two with his pincers to show how they move.
Now, what would happen if the gyro components are not tight enough. It will clatter/rattle, probably.
There comes the bit from my previous post: "Bear in mind that although the cameras are using electronic auto-focus for photographs we have gyro optical stabilization when video is recorded."
The sound can be heard if you switch from one to another camera too.
So in conclusion I think that the noise is coming from the gyro mechanism.
I`m very curious for the opinions of the people who bought A9 2018, I`m almost sure that they can hear that too because Samsung probably have used the same basic mechanism inside.
May be I should write to samsung support for this. But I`m not really sure that they will give me any details.
Thanks for the reply. I found out a topic very similar to mine.

Nope, this noise only can be heard when I shake my phone or when I put it on a hard surface.

It might be carrier dependent. For example when I call a person who is on a carrier with low in-call volume, the rattling noise is like negiligible, but when I call some people who are on a carrier with high in-call volume, the rattling sound can be heard. Also, the sound doesnt come up when I dial using whatsapp, skype or messenger because of low in-call volume in those apps.
Maybe the housing of this phone is not perfect enough to hold all components tight, maybe. If there is a suddenly move of the phone or a high vibration of the speaker, some components will shaking inside and make this noise.

Just noticed that the strange rattling soumd during phone calls was due to the volume up button. It is slightly loose. I dont know if it was like this since beginning or it happened due to usage of phone and idk if its worth to take it to service provider because they might tighten up the buttons but it might become loose again with constant pressing.
Can you remove the cover from your phone and check if your buttons are normal or if they make a noise too when there are vibrations (sound) coming from earpiece ? Please try to dial anyone, with highest in-call volume , do not test the receiver using samsung tool or any other tool because they play soft sound and hence doesnt cause enough vibrations for the volume up button to rattle.
It might be possible that due to cold temperature the frame would have contracted because the enclosure is actually Polycarbonate and not metal (Polycarbonate expand and contract much more than metal frames), (thermal expansion and contraction), which have left very tiny gap in the enclosure of button hence making a gap to allow the buttons to vibrate or make rattling noise? Ordered a slim armour case from amazon.. hopefully that should suppress the issue atleast until temperature rises back to normal in my region.
Just visited a Samsung Service Center. Their words were "Sorry Sir but that is not an issue. I know that the button which is directly infront of the movable camera causes this noise. You might be wondering how I know this, there were 5 or 6 more people who came up to us with same issue on same model. We had opened their phones and noticed that the button which is directly infront of the movable camera (volume up button) causes this noise when phone is shaken or if it vibrates due to sound from receiver. (Without a cover). There is nothing to worry about. Please use a case if it bothers you too much but we cant do much about the design of this model and we cannot open the device because its not faulty."
The rattling noise that you were hearing is the ois of the main camera.
When listening to any stereo sound which is produced from both the earpiece and the bottom main speaker I notice the volume on the earpiece is always lower than the bottom one (about 8/10). Sound quality is a little bit different on them too. Although they still can produce stereo effect, but when compare them side by side it is pretty annoying, they do not produce a good sound balance. I tried cleaning the earpiece slit but it didn't help at all.
Does any one notice the same issue? Is it normal with this kind of speaker design or my earpiece might be clogged by some reason?

Yes earpiece is low in sound level.

The earpiece is a smaller speaker, deeper in the body of the phone. The volume of it will be always slightly lower (although not that noticeable unless you try to use your phone as a boombox).
