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
Click to expand...
Click to collapse
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.
Now, I know this is not the ideal place to post this kind of issue. I have already posted a thread on the Yarvik Support Forum, but I have also read (on their and on this forum) that their support can be a bit... unsupportive. So I would like to repost the thread I have created there, here.
Dear Yarvik Support Team,
My sister and I have quite recently each bought a Yarvik Xenta TAB10-201 tablet. My sister purchased it first, and I, being the forever criticist I am, followed a week later.
In general I am impressed with the tablet. It provides good quality for its price, and while it obviously cannot be compared to 'main brand tablets', it still is a very good tablet.
However, there have been a few things that bother me about the tablet and prevent me from really enjoying it, and I wonder if you could be able to help me.
The tablet sometimes has the issue that it does not register the touch inputs correctly. I mainly notice this while browsing the web (using Chrome & Stock webbrowser);
it can be very hard to open / close tabs, and when I am scrolling the tablet often opens links that I wanted to scroll past. It then can also be hard to open the links I did want to open.
Now, the problem described above is not that big of an issue. It can be an annoyance and I would like to see it fixed, though. The bigger problem is that when I hook up my tablet to the provided charger, and I want to browse a few webpages and / or want to play a game on the tablet, it does all kind of 'phantom touches'. What I mean by that it is that while I do not press on that particular area (or do not even press at all), the tablet still seems to think I have touched that particular area and thus unwantedly launches an app, or unwantedly closes a webpage I was still browsing. It even gets so bad that when I try to unlock the tablet while charging it jumps to the camera app unlock and takes a bunch of pictures. Now, the weird thing about this is that it only happens on my tablet; my sister's tablet (as I mentioned earlier, exactly the same) does not have this problem with either her or my charger. My tablet does have it no matter which charger is used.
I have already looked for a solution on your forums, but have not found a sufficient solution. Some people did provide a solution in the form of 1. Reflashing my firmware, or 2. Installing a custom ROM. I would like to know which solution you can provide for me. It could also be that the touchscreen is simply damaged; I would then like to send in my tablet for repairs.
If any of you would be able to help me, or have had a similar issue (and preferably fixed it), that would be great. Thanks in advance!
Hi people, sorry if my english is not good.
Hi, thanks for reply me (and sorry if my english is not good)
The problem is LIKE this:
youtube.com/watch?v=iMnaUsH_Wfg
I went where i bought the mobile to repair it and they said "now all is OK, We change the display". But when I was come back to my home, the problem start again.
I come back to the shop again and they change me for other mobile but the same model.
3 hours all was perfect, but then, has started the problem again with the new mobile!!.
I read a lot of posts in Internet but i don't have any solution.
Someone can help me??
Thanks for all!!
Hello, I've tried in vain to get rid of this horrible flicker by flashing various ROMs. Sometimes it helped for a while, but the flicker always came back. Zopo seems to completely ignore this issue. So better don't expect to get a solution for this device ever. As PWM-dimmed monitors and TVs have become standard, unfortunately, it also seems to me that many people have become unresponsive (or rather dull) to this dramatically technical aberration, so the complaints are rather limited. At least some PC monitor vendors like BenQ have become aware of this impairment and offer flicker-free monitors (DC-dimmed instead of PWM). But, actually, PWM doesn't seem to be the issue here...?! I've tested with my DSLR and there are no PWM-typical hard light on-off cuts. Regardless of that, the flicker is visible and is more than disturbing. I've now switched to a flawless Moto G4 Play and will never ever buy any of Zopo's junk.
Hello one big problem I have is while I speak proximity sensor does not work as it has and while i speak maybe notifications open or anything else...
can you please tell me if there is any solution?
thank you
Hi, this is know issue from Xperia 1 II. And sony support know that but there is now fix for this. Sony explained that this fault is because of its shape and size. Correct if i am wrong.
Following, as this is one of the most annoying things on this device.
I think in one of the forums was guy that contacted sony support and they have stated that this is design problem and they cant fix this. You need to get used to it and dont move your phone in the ear when talking.
sensor is on the right side of the speaker, some 5-6mm so try to catch your phone a bit more on the right side and once you get used to that it won't be happening so frequently
