Hi all!
I've got some strange electrostatic noise from the back side of my mini pro (when the screen is on and even off - just listen to it longer). And it turned out that the problem is common for new mini pro (some people just doesn't mention it). Looks like it is hardware one, so it could harm overall device work in the future (no one know when). So this thread was started to collect all related info: reasons, workarounds, solutions, official comments etc. If you're sk17 owner, please, take part in this thread (check instructions below).
Sony tells that the problem was solved. So if you have this issue:
1. Update the software of your device via SEUS or PC Companion
2. Visit repair centre if the problem remains
3. Having troubles with the repairment? Contact Johan-SEAnswers on official SE forum

News
27.oct.2.3.4 update launched. They removed the noise from videos. But it's just a workaround. You can still hear it by putting the backside of your sk17 to your ear with the screen turned on.
05.oct.Cricket Team rebranded to Cicada Team. More info...; firmware update time shifted to late October - early November.
12.sep.: SE promises to solve the problem via software update (check this post for details). The same day me and BlackArty got similar emails from Russian SE Customer Support, which promised to launch that update in mid-October.
SE really approved the problem? Check Linkinsoldier post for details.
Thanks to sxxorp we have massive update. Check the official thread.
All sk17 owners! Please contribute to the related thread on SE official community! Don't let them to forget about the problem.

You can use the following template (bold text should be replaced by the data of your sk17):
My mini pro has electrostatic noise when the device is active.
Device model: sk17i (your country)
SI 1249-4753
Prod. week: 11W28

All the info could be found on the sticker under the battery.
What devices have this problem?
At the moment both SK17i and SK17a are reported to have this issue. Production weeks mentioned: 11W28, 11W29, 11W30, 11W31, 11W32, 11W33, 11W34, 11W35, 11W36, 11W37, 11W38.
How to check the device?
Listen to samples to know what kind of noise we're speaking about.
Turn the screen on, place the backside of your mini pro near your ear and here it is (the best part of the backside to 'enjoy' that sound is upper left corner, right under the headphones jack). Though sometimes you can hear it even when you're calling someone if the environment is quite enough. And it's still here when the screen is off (not continuous if there's no active apps; several short clicks with silent intervals). Actually, the noise is here when the device is active (even with the screen off). For example, connect headphones, start the music player, lock the screen and check the noise.
Please, share the results of your tests in comments below and take part in SE community discussion mentioned above. This could help us to know more about this problem and get it faster to solve the issue. If you do not have the noise, please, make a short video in silent environment, upload it to youtube or somewhere else and share the link with us!
Contact SE support in your country with the problem description via email, twitter, facebook etc. If you'll get some interesting info from them, please, share it with us.
The device is checked. What to post?
Please, first of all contribute to the related thread in official SE community (look at the BIG red text above).
Do your device has that noise or not? If not, proove it by video sample.
Info about your device: SK17i or SK17a, country, SI and production week (a string like "11W28", which means 28th week of 2011; you may use the template under the BIG red text). All could be found at the sticker under the battery.
(optional)Some extra info that could be useful for other sk17 owners: probable reasons, workarounds / solutions, official SE answers, comments etc.
Official information
Here's the related discussion on official SE Community:
http://talk.sonyericsson.com/thread/22121?tstart=0
We've got more info. SE promises to solve the problem via software update (check this post for details). The same day me and BlackArty got similar emails from Russian SE Customer Support, which promised to launch that update in mid-October.
I sent an email to Russian SE Customer Support. They told me to go to service. Without any comments. It was done on August, 20.
UPD The phone got back on August, 25 with software reinstalled and noise persisted. Though they told me that 'there's no described problem'.
sxxorp has got a little bit more info from them. Check his posts: #31 and #32.
Somewhat like the first official approval of the problem: SE left the comment under one of the 'noisy videos':
Hi Everyone, we are investigating this noise that some people are hearing. Please be sure to check out our forum at our website for any more news. - Jeff

There's the similar comment in the official thread.
Probable reasons
No ideas for now.
Workarounds / solutions
Removing the back cover reduces the noise.
Looks like plugging USB-cable in (doesn't matter if it's plugged into laptop or charger) removes the noise. But still some quite clicks (not so annoying though).
(thanks to BlackArty)The noise disappears when the processor is loaded heavily. For example, run the StabilityTest (could be downloaded from Market for free) and check your device. You'll hear only 'metronome clicks'.
Check post #3 and #10 by sxxorp to find out what else we've tried to do.

P.P.S. My mini pro is SK17i, 11W28, SI 1249-4753.
Thanks for confirming this issue. I was vaguely looking at getting the Mini Pro but if this is such an issue I don't think I will bother for now.
Hi, thanks for dealing with the issue, you wrote many new info on the topic - and it doesn't sound good... seems like a hardware-plan related construction problem... Many sample videos contain the same problem - in fact I haven't seen one without it...
I'd like to have one Mini Pro, but this holds me back.
Is it the same with the Mini (ST15i)?
You said on the official forum that you contacted SE - how, and did they answer?
Ideas:
- any possibility to separate the mic from the 3.5 jack, with some small material?
- plug-in only the USB-cable (or a chunk of it...) without anything on the other side (no laptop/charger) , does it work?
(- maybe recording with headset connected , so the jack is plugged-in? (or does this prevent the phone to record video with sounds?))
sorry if these can't be made, I'm before purchasing the mobile I can't test the ideas... but it'd be good to have a solution!
I got an answer from SE customer support. They told me to go to service.
I did it. So no tests for a while. Sorry. I'll give more info when the device comes back. Maybe, someone else will test it? I'm sure that there's another sk17 owners on forum
As I told you there are several sample videos on youtube, as I can recall all sharing this problem... I suppose Minis without keyboard don't have this noise, jack was placed totally different.
What could a service do with this problem?? It seems badly planned, rather than faulty hardware...
Keep us updated: your phone becoming OK or not (and how they did it...)
noise confirm
i know i have this little chirp or scratch noise. exactly like the video in the 1st post of the russian youtube. i'v tried to record in vga and same thing happens. i love the phone but a lithe disappointed in the recording chirp background. not horribly bad but still bad.

So it is just the Pro and not the Mini that has this issue?
I'm not sure, but I've seen videos made with the Mini that was a lot clearer. Their inner structure is different, it ca easily tur out that the Mini has a lot more space to avoid this problem (despite bigger size the Pro is more compressed because of the keyboard) and the jack is on the other side...
I have the mini pro sk17a if that makes any difference
Sent from my SK17a using XDA App
When your's was made? (see Sur1k's 1st post how to check)
In the meantime one forum member from the Hungarian SE-forum called SEria (http://www.seria.hu/forum/viewtopic.php?p=120572#120572 in Hungarian language) tried to check some options, I'll provide a rough translation:
he made 4 videos: normal, USB plugged (in charger also), headset plugged, headset+USB plugged:
http://www.mediafire.com/?y4k4cvwdjxns4v8
The video background noise becomes normal only when USB was plugged. He also suspects hardware failure...
Production week: 11W28... the same.
Plugging in only the USB cable, while the other end is free doesn't work on his device (if it worked, good video could be made with plugging in only the cable as a primitive workaround...)
UPD: we have a 11W30 with the noise
Can anyone confirm or deny that this issue happens with the SK17i model? I'm looking to order it next week and if that's the case I'll opt for the standard mini.
damien-tt,
well, let's read the thread name carefully. I think there's an answer to your question.

It seems likely that it's one piece of hardware inside interfering with the camera audio, which unless SE revise the internal workings in some way seems unlikely to be fixed anytime soon.
i can confirm this! Same problem here :/
edit: if the problem is the microphone, why does calling work without problems?
edit2: even WORSE: Try putting your phone on your ear "WHILE THE DISPLAY IS ON!!!!"... you can hear the voice too!!!

Ear on display you can hear the voice? What kind of voice? I'm thinking about buying this phone because it's perfect, but this problem made me curious. Is everyone with mini pro having that clicking noise?
when the display is on and your holding the phone like you're trying to call someone... you can hear the sound WHEN ITS TOTALLY SILENT around you!
Same problem, when you're making a call.
But this is only noticable if it's really totally silent around you and i think this might be related to the problem, cell phones tend to make "noices" to other speakers too... maybe this is related...
But the cam noice is more loud! Although, since I dont make any videos with the cell, it not that big of a deal for me! I'm keeping the phone,...
sxxorp,
my fault.
himuraken,
thanks for the report. And sorry for my poor reading skills
About the noise when the screen is on. Yep, I had the same problem. Turn the screen on, place the device near your ear and here it is (for better experience listen to that "hi-tech music" from the backside of the mini pro).
Still no news from the service...
Sur1k: No prob
Just inform us, when sth happens.
Hey i'm new to here....but i will get straight to the problem..
i been having problems with my mic, the one in the top. I thought it was a software issue but it was not because i tried flashing lots of stock roms but still didn't work...my other mike is working fine...but when i turn the speaker on the phone uses the mic in the top, and when video catting also the phone uses the top mic, so i cant do anything so my question is that is there any way to set my second mic to be used for everything...like for video chatting on skype and tango, instead of using the mic on top, can the mic in the bottom be used?? is it possible to set the lower mic to be used for everything?? hope someone will help me thank you!
please somebody help me please
I don't know the answer to your question, but dude, you gotta wait longer than a couple hours before whining.
This is a development forum, not a tech support forum. No one is paid to sit around watching for support request posts. People answer posts of their own free will, on their own time.
EDIT: actually, I'm curious now. You say you're having issue with your top mic. Do you have a case on the phone? If so, does the case have an opening for the top mic? If so, are you sure the mic opening is clear of debris?
i'm sorry.... no its doesn't have any case or anything...and its clear...i even tried to put a small pin into it to see if there is anything stuck inside it, but their was nothing

Exactly what is the problem you are having with the upper mic anyways? You never say.
I don't know of any mods that will re-route all mic functions of the upper mic to the lower one... So if the upper mic is simply not functioning, it sounds like it could be hardware fault.
Your only option may be to send it for repair. Since you say you tried flashing a bunch of ROMs, you'll have to flash back to stock and reset your flash counter if you want any hope of warranty coverage. Otherwise you'll be paying for the repair job.

May or may not work, and will only work until a reboot, at which point he'd have to do it again.
If he has warranty, he should send it in. Otherwise, he could crack the case open and inspect the top mic to see if the rubber housing is seated properly. It might be partially blocking the mic.
thanks for trying to help guyss....i did try that before but it didnt help at all

So send it in for repair (hopefully warranty covered), or try to do phone surgery yourself. Those are really your only options.
I have exactly the same issue. Top mic is not working and even replacement of the board with mic, vibro-motor and mini-jack did't helped. I've realised that the problem is with a condensator or a chip on the main board. I also would like to find the modification wich can change top mic to the lower one. Please, if anyone knows how to do it, let me know.
Hello, I have searched all over the forums but I can't seem to find an answer.
I have a Xperia X10 mini and I'm having problems with very low volume in my front speaker (earpiece, the one use to make calls). I'm 99% certain it's a hardware problem, not a software bug in a custom rom (however I'm using the latest miniCM7).
I want to know which replacement part I need to fix this. I mean, is it possible to buy the front earpiece or does this come with the LCD or something. Also, does anyone know a trustworthy place to buy this?
Hmmm.. Try to go any near shop that they can repair phones. Maybe that should help you.
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...

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.

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

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
First of all let me say I tried to use the search option. After redesigning the forum, honestly I don`t know how to use it. I hope I am not the only one who is confused with the new search.
Anyway about my real problem. Bottom speaker stopped working, actually it did work but the sound was so distorted with the low volume. I decided to buy a new speaker and replace the old one, which I did. But the strange thing, even with the new speaker, the problem still persist, basically it`s the same issue as with the old one.
Does anyone can explain to me what is actually the problem here, is there anything I could do here? Also to mention I received the update with the android 11 in the meantime, issue is still here.
I would really appreciate much your help here.
