Bad call quality - Xperia Z2 Q&A, Help & Troubleshooting

Hi...
I got a xperia z2 prototye. model 6503.
Everything is working fine, except the call quality. i can hear and understand very well, but the other person has echoes, and very bad sound..
When I use a heatset, there is no problem. and it is almost good, when I put the phone on the table, with speaker on. The problem is worst, when I hold the phone on my ear..
Is it a hard- or software related problem?
I´m now on 17.1.A.2.55
THX

Since others have not complained about this issue, it looks like a hardware issue. Maybe your microphone is faulty?
Take it to Sony and get it checked.

I did some voice recording, and it is brilliant.

Try turning off the noise cancellation feature during calls, and see if there's a difference.

Well it's a prototype so who knows...

As you read in my thread my voice recording is anything but brilliant......what did you use for your testing?

I first became concerned when I recorded an outgoing message for the phone's default answering machine...As a test I download a voice recording app that let me turn off noise suppression/cancellation.
It brought it from unusable to usable, still not good. But I think your suggestion is a good one, I just don't see why a software tweak improves on something that seems more like a hardware problem. I say that because I can't find a single thing on the web aside from these two posts stating any concerns about it.
This is killing me...turning off noise cancellation only improves the quality in that particular app. Turning it off in the Call settings didn't change anything. I can't record an acceptable answering machine greeting no matter what I do.
EDIT- I also have unlocked my bootloader and thusly lost my DRM Keys... OP has a prototype Z2, perhaps something there?

Same problem here, and mine is not a proto
my nephew and my gf got Z2 too, and same problem...
we hear wel, they can't hear us clearly

Considering that the quality of sound that comes out of the speakers when we hear music, it sure is software problem! In Xperia Z was the same thing in its release!

non proto:
when I'm on earpiece, the caller will always be breaking up. I'll have to disconnect and return the call before everything's crispy again. though there are times they'll complain of not hearing me properly. turning off the "background noise" option seems to help but they'll tell me it's noisy as fuuu.
lol hoping for a software fix I guess.

i have had a problem with people being able to hear me clearly ! if i let the phone even drift slightly away from my mouth people say they cant hear me or im breaking up ! ! i had a GS2 before this phone and never had a problem like this . this to me is a hell of a major flaw ... if you struggle to use a mobile phone as what it is designed to do .. then it aint worth a s**t ! i have to keep the phone pressed up against the side of my face all the time im using it ... i cant just wedge it under my chin like i used to do with the old phone. maybe if i root and install a custom ROM it would help this issue ???

First time I've seen my problem described to the letter. It's especially bad when I hold the phone with my chin and no hands. I turned off noise cancelation under phone settings and people stopped complaining however a few people complained of an echo... Lose, lose. Btw, I'm rooted with a custom ROM and nothing has changed.

oh .. i thought rooting and a custom ROM would solve this problem ! i also have noise cancellation switched off .. but still if i let this phone drift even slightly away from my mouth , immediately people say im breaking up or they just cant hear me ? what the hell good is a damm phone that people cant hear you on ! i can hear them very clearly .. it must just be a crap microphone in the phone

This worries me. I'm planning to buy the z2 but if people in the other end have issues hearing you then I might pass. It's a shame.

There should be a speaker voice enhancement option in the call settings menu, not sure whether you've tried this or not but might be worth a shot

i wouldn't of bought this phone .. trouble is you don't get to test the call quality or anything like that before you buy the phone ! yes now its easy to read this forum about the problems people are having . so wish i had waited and read this forum before i ordered mine. think i will be buying something else in the near future, and try and sell this one

Maybe people should report this to Sony as I don't get any complaints from the receiving end so far. My only complaint is the sound quality of the voice in the earpiece is not rich. The voice lacks low frequency.

On my handset I constantly have hissing noises during a call and voice breaking up intermittently, but not when I'm on speaker or headphones then it's all crystal clear.
Mine is 14W16 and I've already had it replaced but the problem is still there (replacement device also 14W16).
Does anyone else experience this?
I've already disabled/enabled microphone noise suppression and speaker voice enhancement, but to no effect.
EDIT: My third device (also 14W16) still has this problem, maybe a faulty batch or is it probably a software problem?
EDIT2: Seems to be a software related problem. I have flashed the new 17.1.1.A.0.402 rom and it's almost perfect now.

It seems like a recurring problem...
Hi Guys,
Here's my post on Xperia Care (3 threads dealing with this specific issue):
"I've had the exact same issues since my very first call. I am pretty sure it is a hardware issue and not software or use-related (my phone has never been in contact with water, the issue started in an "out-of-the-box" context and ALL the people I've had over the phone guessed that I changed for a new one just because they could not hear me as clearly as with my former HTC HD2 which I'm starting to deeply regret for this basic use of calling for a phone!).
Searching over the web and through this forum, you can find many people complaining about this problem and saying that a standard exchange did not solve it: would it be a batch problem?? For info, mine is a simlock-free purple model bought in Germany.
Another thing, using noise cancellation is even worse according to my callees so I guess I'll never use this feature, then... All details provided by you guys are described by my friends when I have them on the phone: hissing, hearing me in the distance (muffled sound), hearing their voice in echo (bad Z2 speaker=>mic interaction), vibration (resonance/vibration due to the phone design itself??), hearing like intermittent wind gusts and very very bad sound when I hold the phone between my cheek and shoulder...
As if this would not be bad enough, now the camera application does not record sound anymore when filming (it used to be OK before updating to newer version through PC Companion). Instead of proper sound you hear constant hissing. After a lot of tests I've realised that it now uses the noise cancellation mic instead of the primary one. When running a mic test through Xperia diagnostics menu you can hear back that hissing and no sound at all. Doing the same test through the *#*#7378423#*#* menu gives a different result since I can hear the recording perfectly well (because it is using primary microphone)."
After rebooting my phone, the secondary mic is now working. This leaves me very puzzled now: would it be a software issue in he end??
I'm phoning French Xperia Car hotline tomorrow, keep you posted.
Cheers

Any update on this? I just got this phone for my fiancé and it seems that she's having the same issue. I can't hear well.
Must have something to do with positioning the mic and how far it is from the mouth. More than a design problem than a hardware one methinks.

Hi SooSpecial,
Xperia Care had no explanation about this; they advised me to file a standard exchange procedure with the seller, which I did.
I'm now waiting for my new device, hoping I won't have the same problem anymore.
If not, I would ask for a refund and go for a G3 instead. That would be a pity because I really like the Z2.
I'd advise you to have your girlfriend's handset changed asap, otherwise you would have to go for a repair procedure w/ Sony, which may take approx. 1 month, leaving you without any replacement smartphone if it was a simlock-free one...
FYI, this problem has also been reported on Xperia Care Forum in 3 threads on Frandroid (french forum) and on some customer reviews on Amazon (as far as I know).
Good luck with that

X10 In Call Volume

Anyone else's In call volume very low? even though its on maximum volume? I cant seem to hear very well unless I put the phone on loudspeaker. any ideas on this one?
cheers
Yup. I am on .14 and it is awful. I hear the .16 update fixes it though. There are so many good things about this phone that I couldnt care less about this issue though at the moment.
Nope. I have .16 and it's just as bad.

Cheers mate, I was just about to follow the debranding tutorial to update to 1.6 to improve my In- Call volume.
I have also heard that 1.6 offers an improvement in this area.

I'm actually thinking of unbranding my phone just because I can. But it's just to get rid of like one or two pre-installed programs.
i am on firmware 1.6 and it doesnt solve anything, its really really bad! the volume is ridiculous I can hardly hear anyone unless I go into a room where theres no noise at all! SE need to fix this
volume at max is not even iphone at half
Volume is terrible, i keep squeezing the phone into my ear.... what i don't understand is who ever listened to the phone and said ooooh this is good, how is he not FIRED
if this phone ever gets released in the US with the same problem i am complaining to the FCC. it seems someone to do something about it, (remember what happened to Toyota?)
I honestly dont think a firmware can increase/fix the volume issue, i honetly think the speaker is at its limits, i even hear distortion some times, telling me my volume way to loud for the speaker capacity, although i can BARLEY hear something.
Terrible
Yea, I cant say that the volume is loud, but I found out a solution that works for me.
Actually the screen seems to pick up the vibrations from the speaker, so if you instead of holding your ear against the speaker move your ear slightly down so that you actually have your ear on the top part of the screen instead... then the volume is much better!!
Just a tip.
And for SE: I noticed that only the higher pitched frequencies causes distort in the small speaker. Analyze the speaker and identify which frequencies that causes distortion and filter those frequencies out. Sacrifice those frequencies for a louder volume!
Regards // R
I read somewhere that they put the phone in test mode and forced the volume higher and worked.
Which would mean the hardware is capable of higher volume its just bad software.
This issue bugs me big time, and I'm quite dissapointed :-/
Any news on SonyEricsson solving this issue?
I've read that the X10 mini does have a much better loudspeaker. How can this be when it's an even smaller phone?
I strongly(!) hope that SE will fix it! A phone that is useless for phone calls? Than I can buy an iPod touch :-(
there is a 'volume hack' app but works only for rooted devices.
same problem..can hardly hear when on the street or in public place.
i enable speaker..and keep the loudspeaker near my ear.

Personaly I don't think that this is the way you have to make calls with a top of the line smartphone ;-)
Does anybody know if Sonyericsson is aware of this low volume issue?
Do they want to adress this issue with a soft- or hardwarefix?
Hopefully the update will come soon

Yes there are many problems with X10, i think X10 problems will be solved soon after the update 2.1 let us hope for the best
i use the speaker all the time

Actually, the number of problems is far, far, far, far, faaaaaaar less than you think it is. Being on a board for people needing technical support for their phones will make you think there's a lot more anger and problems than there really are. It's the nature of the internet.
Think about it, if there were really that many shopstopping problems, the phone would have gone through a recall by now. You can't let this forum (or any other tech support forum) give you any sort of indication of percentage of users with problems.
Same problem here... German o2 X10i (R2BA026). Speaker volume set to max. but still can't hear the other side It's a shame...

[Q] Camcorder recording very muffled sound

I have noticed that when I record video with the Thunderbolt that the picture quality is out of this world but the sound quality is terrible at best. I can barely hear my TV playing just 6 or 7 feet away from me. Anyone else have this problem?
I am running Infected ROM but have had this problem since it came out of the box.
Also, I was wondering, if I called VErizon support on this, could they tell that I had my phone rooted just by being on the phone with them?
This issue has been discussed on xda as well as a few other forums (htcs own community as well). I havent found an explanation or anything that fixes it unfortunately. I'm kinda upset about this since I'm constantly taking videos on my phone.

They don't know you're rooted. I exchanged my Moto droid 4 times, it was rooted each time. I often called them and they would just send me another. The buttons kept going bad on my phones. Bad luck I guess.
It uses the mic at the bottom of the phone (same one for phone calls) so make sure you're not covering that up. And it seems that unless whatever you're recording is close, you'll have issues. There was a post somewhere from someone who contacted HTC and was told it was due to the noise cancelling software
Well at least if its software related maybe it can be fixed in the first update. It's a shame to have such great video quality with such horrendous sound.

How are you finding the sound quality on Viber on the Z2?
I find it to be very quiet & I can barely hear the person I'm talking to & they can barely hear me, emailed Viber support but they weren't much use even though I pointed out that Viber on old Galaxy S3 was nice & loud in both voice & notifications sounds but on the Z2 it is way too quiet, tried Line & the sound is good on that but the app is bloated & the smileys are crap lol.

Same here. the sound quality is crap. very low sound.. when I am outside i open speaker and put it on my ear and barely can hear the sound.. And the sound of beeps always happen even with speaker on. I had before samsung phone galaxy mega 6.3 and the sound was awesome. Am thinking to buy bluetooth headset to use it instead of the phone
Yeah same here mate, even using it in speaker phone mode the sound is way too quiet & muffled. I'm gonna email their support again, would suggest you do the same. The more reports & complaints they get about it will make them do something about it.

Any update? I am having same issue. Voice recordings in Viber are very poor. I have contacted online Sony support. And actually it happens not only in Viber. And they told me it's hardware issue. And advised to do firmware restore and hardreset. But my wife has Z2 too with same issues and both phones from different countries, different stores. May be Sony uses new way to record sounds or poor support of microphones in API.

No. I didn't do any of those yet.
OK, guys, just did software repair. Nothing changed. Don't go for it and don't waste your time.
Well I emailed Viber support about the 4th-5th Sept & only got a reply from them yesterday about a month & a half later asking me to install a debug version that will wipe my message history, they suggest to email message history but AFAIK there is no way to restore it.
Pretty pathetic support if you ask me.
at least it's good they replied you.. They didn't reply me till now and it has been more than a month.. now am thinking to buy bluetooth headset just to get rid of this annoying problem but then even with bluetooth headset you can't answer viber calls directly like normal calls.. i read on other threads someone from viber support team said they don't yet support bluetooth headset.. as if viber not everyone use it and majority use normal calls. it's really ridiculous

[Q] Poor call quality on the Xperia Z2

Maybe some one can help me out here....recently purchased a Z2 and everything is running wonderfully on it, BUT I have struggled to get get good quality out of the earpiece. I can not pinpoint what the problem is, and my service provider and local Sony Centre refuse to help me out because the phone is imported. Almost every single call I have made has a terrible static, tinny sound. At times its better, other times I cannot even hear the other person on the other line. I have changed sim cards which didn't really help, tried other service provider sim cards which helped only a little. The strange thing is that when I run the diagnostics app on the phone, my ringtone playing through the earpiece is crystal clear and sounds really good. Also if I plug headphones in, the call quality improves immensely. I have read that the .314 firmware upgrade is supposed to enhance the call quality of the Z2 but I'm not sure if its addressing the specific issue I am having, also the firmware update is not available yet in my country. I don't want to send the phone back to Europe even though I have a warranty through the retailer that sold me the phone because who knows how long it will take for them to sort this out?! Has anyone experienced what I am experiencing? Do all Z2's have crappy, static, tinny call quality?

Hey there, sadly i experienced the same. I came from SGSIII, and the difference of call quaility is not compareable. I've heard and read that this is a Sony illness and there's been long time ago. Recently i flashed .314 ROM however that hasn't been released in my country either. I don't want to depress you but the quality hasn't changed at all. Tried every f....ing Sound Settings, but not a step forward.
I'm desperately waiting for the next release of firmware, maybe there'll be some improvement.

Thanks for the feedback. Today I started using a different service provider and I must say that the calls have improved a lot. Will be testing more networks through out the week, but i think the call quality issues may be network related! The calls still have a fuzzy quality to them but not as bad.

Interesting. My provider(T-mobile) says they provides HD call quality. Honestly: i believe them. Ridiculous, the first Ericsson phone i had gave me better sound. I think it's all software related, c'mon Sony, don't ruin this great phone with this annoying incident.

I must say its a really confusing issue. I am getting mixed results on the other sim so far, when the calls are good then they are GREAT! I have reverted back to my old sim and am now getting OK call quality, still fuzzy but bearable. It just confuses me that the diagnostics tests gives me a lovely rich sound out of the earpiece, but then an actual call is absolute rubbish! Maybe its an antennae issue???

[Q] Noise/hissing in speaker during calls (quiet)

Hi, everyone!
I'm G850F owner, and I have quiet noise/hissing in top speaker during calls. It's there all the time GSM is working, including tones before pickup.
It sounds like old radio receiver between stations. Doesn't disturb phone calls, however it's still very annoying. Not everyone hears it.
It's constant volume level, independent of call volume, so it's best heard when volume is at minimum and between dial tones. Same sim-card sounds ok in other phones.
I've heard about "Comfort noise" thing, but not sure that is it: I've tried 10+ different phones and smartphones, and only 1 old Nokia sounded like that. And it's not comforting at all
I've even went to shop and they gave me another device to test - same result. Device was from same batch as mine, however.
So... the question is: do you hear it, how is it comparing to other devices, and do you have some more information?
P.S. When recording call and then listen to recording using same speaker - no noise. So it's either interference from GSM module to speaker, or I don't know what ) Maybe it's software? Then there should be a way to remove/lower it.

Hmmm i do not know what it is. But just FYI I have come across a few threads about this issue for the Alpha on a Swedish Android forum (Swedroid) . A couple of people there are having this issue. So far I have not seen any solution.
Interesting! Just got mine and I have the same problem. So it's just us or everyone has that problem? When I use the earphones it gets a whole better! Is it common or I should return mine asap?
Common unfortunately. I've got used to it ) Not all people hear it at all.

That's a pity coz I was almost sure that I got the perfect phone except from that apparently! that sound of a frying pan drives me nuts! Anyway since everyone has the same issue and I don't have a faulty one I can get used to it! Thanks a lot for replying!
