Unable to hear a thing - Xperia Z2 Q&A, Help & Troubleshooting

I have been using the z2 for over a week now and the call volume is so low I can't hear a damn thing in HK.
Volume is up to max, the equaliser etc all bumped up max.
Is this phone faulty? My other phones gain is totally fine but this phone is unusable

Weird, might be defective because mine's loud and crisp when taking phone calls. Try flashing a different firmware and if that doesn't work you should seek your warranty.

Just for your information: for talking at home I use lowest volume level (it is enough) so probably yours is defective.

Phone is not rooted yet so using stock. Hence the lack of gain boost as I am waiting for the ta backup on the z2 as it is still early days.

Try factory reset and reboot 2-3 times before using.

Does this seriously work as the gain is set in firmware I thought

Weird Buzzing Sound From Speaker

I was using Gingerreal 1.1.0, based on KPN and yesterday noticed a weird 'bzz' sound when playing music (stock music player, then winamp). Thinking it was a GR bug, I flashed a fresh, stock KPN and still notice the same distortion. This happens even when listening to ringtones, in the system app. My question is, is this common at volumes of 10/15? Or has my speaker gone bad, and I need to get it checked? I use 320 kbps mp3s, so the quality of the mp3 file isn't in question (happens with ALL my songs).
Thanks!
It happens to my mp4 player, computer and phone. It should be either the jack getting old, or the disk drive getting old. just a guess! Because i've searched google which turns up no results.
I've had it ever since the day I got my Ace . I'm still thinking whether it's an antenna problem or speaker fault .

I meant my loudspeaker. The in-call sound is most likely carrier dependent. Even my bootsound is surprisingly loud. And thus distorted. Time to get it checked?
PS. I should revert to the stock Asian Froyo before visiting the service center, right?

Yes , the sounds came out of my loudspeaker too .
So you say it is normal? But shouldn't the sound be normal even at the maximum specified volume? What's the point of having levels till, say 15, when only till 9 the sound remains clean?

You may have harmed your speaker previously .
That's what is even more surprising. I've barely used it. All the side stickers are still there. And I usually keep it on vibrate. Sucks really. You take full care about scratches and stuff. Then this happens. And the service centres will probably ruin it. Happened with my PSP, iPod.. :/

You could try going into service mode and changing the pre-amp in the sound settings .
To get into Service Mode , download SamServMode .
BE CAREFUL ON WHAT SETTINGS YOU SET THERE .

Can anyone confirm if their speaker doesn't buzz at loud volumes? I want to be sure before I claim my warranty at a service centre. People here in India don't always accept claims..

I think you're referring to lags. I get sounds as if there's something that's on the speaker filament, and touching it. BTW, what do I change in the Service Mode? I tried rebuilding speaker values, set pre-amp for MP3 something and speaker to 0 db. No effects. It really is messed up..

[Q] Call Quality - Other End

Hi all,
I just got the Z2 for my fiancé as she wanted the best camera in a phone. All is going well except for call quality.
She hears everybody just fine but people complain that they can't hear her well. I've been reading online and some people are having the same issue even after replacing the phone.
Is it something to do with positioning the mic or could be a faulty hardware? She has an average (small) female face/head size. Could it be because the mic is just too far away from the mouth? Or something to do with noise-canceling mic?
EDIT: updated the phone to 402 and still she still has the same issue
I have the same issue, have to raise my voice slightly for people to be able to hear me properly

It could be caused by faulty SIM card
I one had this issue with another device and I was using a normal sized SIM cut to fit micro sim slot, one I got it replaced at my operator then all went marvelous
It's a proper so card so not sure it's that but I will test another just in case

Same issue for me too. Thought it might have been my case. Both happy and sad it's not. Shame it's not fixed in the latest firmware. Hopefully a future one can fix it.
Same here
But it do happen for most calls

Same here. Had to buy a handsfree, because i can't use the speakers when at work. NON disclosure stuff. I'm a bit disappointed at Sony actually. But with the handsfree everything is great.
My friends Z2 doesn't have these issues though, latest firmware.

Here too... Call quality on other end is not good enough till u speak.
Have had complaints about my voice quality being poor as well...
Is this an isolated case? So far I haven't heard anyone complaining about my voice. What does the voice sounds like on the other end? Choppy, muffled, too soft?

Sound like Morgan Freeman from the wormholl , very ****y and on seconds,other party is loosing your whole words , i also discovered it isnt on each call , and will try to low or high the in call volume to see if it effects somehow to this bug/fault but obviously its not a single problem

Same problem
I have complaints with almost every phone call about my sound quality. Have to speak louder or take phone off my ear and put microphone closer to my mouth.
Got this problem as well. Thought my was an isolate case but seemly it isn't so. Hope Sony do something abt it in the next firmware update

Wow, seems that everybody is having the same issue! How do you guys manage to live with it? I'd go nuts.
Anybody NOT facing the same bad quality issue? I got the phone replaced, let's what what my fiancé thinks about it.
I am waiting for replacement at Monday , arriving a new bach , will report after it , but mine alwso has gaps and uncentered camera , i cant believe sony make so much deffekt devices and thats the flagship for 2014 ..imagine in 2015 sony will sell a phones that ruin themselfs in your hand

if you let the mouth piece drift even slightly away from your mouth , people say your breaking up or they cant hear you ! seems that Sony have a crap microphone built in the phone . and what good is a phone when people struggle to hear you ????

Z2 problems

My partner has had her z2 for a couple weeks. And she has always had iPhones and me mainly androids. But she has found it hard to use at times. For some reason 3 or 4 times a day over past week it has crashed and not responded. And also turns it's self off. And while in walkman app could not select songs only way I managed to get it to work was uninstall all updates then the songs were clickable. Then upgraded again and it still worked. Any one else had similar problems? Thanks
Sent from my HTC One max using Tapatalk
You shouldn't be having these issues. In my experience the phone is very stable.
The only time it resets on me is when I pull the SIM card. I'm not sure why it does that because it's not necessary.... But anyway
Try doing a factory reset and all that. If there are still issues call Sony support and get the device replaced, or just do a 30 return/exchange.
Sent from my One using XDA Premium 4 mobile app
Yes i had these exact issues with a defective unit, it seems that replacing the device fixed it alltogether
Take note reflashing my firmware didnt fix my problem, if it doesnt fix yours then get a replacement

It's no bigger than the cutouts for the headphones on most cases so this should be fine to use on a phone with a case. It is in fact the same size as most headphone connectors so if a headphone fits so will this. Just an excuse to spend 24p really lol that's why I bought one, no reason to.. No reason not to. Although I do think being able to activate the flash with one click even with the phone in standby is pretty useful for me personally.

Any effect on battery life?
My G3 (D855) seems to be having issue detecting anything that I plug in the headphone jack other than the stock headphones that came with it. I tried plugging in the pressy button and a portable speaker on separate occasions but they were only detected momentarily. The button works fine on my old phone which is a galaxy note n7000 so I'm pretty sure it isn't spoilt.
Anyone has any clue about this issue? Otherwise I'll probably send my G3 for repair since it's still obviously still under warranty.
I am having issue with Pressy on g3 and my other phone so it's not the phone it's Pressy.

Sounds like a software problem with compatibility? I don't see why some work and some don't.. Hopefully gets fixed with an update.

Noise canceling headphones show up as mic?

When I plug in the notice canceling headphones that came with my z2 it shows up as a mic and I cannot hear any audio through the headphones.
Is this just me?
Sent from my D6503 using XDA Free mobile app
it seems to only do this when using skype for me
other than that it seems to work 99% fine
Did you put your phone into water? Maybe there is still water inside preventing a 100% clear connection
Mine are working fine too
No water damage. I started getting this issue after upgrading to extenz 4.5 but I've tried downgrading but issue still persistents.
Funny this is if I insert the headphones then restart the phone then they work fine.

I had this same behavior. One of your 5 minijack pins in the phone might got damaged.
Try wiping data for SmartConnect just to be sure it's not a software issue.
hmm that sounds awkward

Hi,
I have the same problem here. The earphone used to work as a charm but one day just stopped working and the mic signal is on when I plug the earphone in. I have already tried wiping Smart Connect and Restoring the phone to Factory Conditions through Sony Companion.
Really didn't want to contact Sony over this... Any ideas??
Cheers!
