No. Due to our laws the situation is following. I should apply to retailer that there's a problem with the device. They will send my device to authorized SE service center for check (I could go directly to service, as it was done, but they can't change the devices, only repair them). If the problem couldn't be solved the retailer should give me my money back or exchange the device to similar or more expensive one (with additional payment from me).

I like SK17. It's really nice. So, in my opinion, exchanging on 'silent' sk17 would be the best option. But for now I'm not sure that I won't get noisy mini pro again.

Updated first post. Added 11W31.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
Exploring a little bit the problem - it's more expanded than I thought. The real problem isn't with the video - this static insect noise is many times there, especially when the screen is on, video recording only captures it...

And this sound on longer term doesn't promise good lifetime of the phone... sth electrical is having a party in the up-right part of the device... you can hear it.

I can't imagine that so many SK17i owners doesn't recognize this noise, as it isn't limited to video playback... come on, make this a mass effect!

Well, I wrote about it in the first post in 'how to check' section. That's why I worry about it. It's like bad electric contacts or something similar.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
Please check update in my previous post - any other viable idea?

UPDATE: they've already erased it...

UPDATE2: started a Topic on Facebook Forum of SE instead, pls keep it alive, by posting on it:

@sur1k:

can you please maybe add the issue about "hearing similar noice" during call out of the phone speakers or when putting your ear on the speaker will display is on.

I think this is an even bigger issue for the phone :/
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
Calling I haven't tested yet, but I think its related to the condition when touchscreen is lit, and during calling it's off...

Still I just can repeat: pls BE MORE WATCHFUL, recognize the problem, I think many just didn't realize it, others think its just a simple problem limited to video... no, it's continuous eletrostatic noise, when the screen is lit, put your ear close to the jack's hole... not too loud, but very loud compared to what should be there...

One mate suggested that its the sound of the processor - but I asked why is there silence, when the phone is on charging?? then the processor rests?

@jiminee: I've read your link just after writing the aforementioned paragraph - that's what I talk about! Perfect, clear way of making your voice heard (or your letter be read :D ) I hope others get awaken, too!

@Sur1k: I'd update the title of the topic, to a more alerting one, as recording is just a part of the story, maybe more people would become aware :)

'CHECK - Continuous annoying electrostatic noise in many Mini Pros, when screen is active!!! (captured on all video recordings)'

or sth like that :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Linkinsoldier:
Well, but the sound is still there! At least @ my phone... give it a try:

make a call in a complete silence environment... you can hear it!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
I don't want to...:( People are ignorant, I had to explain for an hour to only 1 people to recognize this problem on a forum...

Considering this, SE can sweep this under the carpet...

I take this back on Monday, try to get rid of it, I hope I'll succeed...

UPDATE: we have an 11W32... I assume we have to wait, one, two, or 3 weeks into Aug, when the phone has been started to sell on the market, and people alerted SE on this topic... so, the devices made this week are maybe OK... from week 11W34 up, or maybe I'm too optimistic...

NEWS!

"Got my replacement this morning and it is '11w31.

Viedeo recording static noise still happens.

phones4u in the UK have told me that all the xperia mini pro's have been 'quarantined' meaning they have been sent back to manufacurer, which I could pretty much guess because of the above issue."

From GSMArena forum...

One fact is for sure, I checked the SE sets that can be ordered - Mini Pro is missing: http://www.phones4u.co.uk/shop/shop_contract_sub.asp?ManKey=5

first sign of hope...

I have also found there is noise interference when using my noise cancellation headphones to listen to music on it, I have never encountered this issue when using them on other phones. Wonder if it's a related issue?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sur1k:
Added. I hear it too. Even during a call.

The first post was updated.

Changed thread name, added info about new thread on SE community and 11W32, added the list of related threads on different forums.

sxxorp, check your thanks meter :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
I had the idea, but was completely surprised with the new thread :D

What the hell? - I thought, but thanks!

Though I have to admit that my title is somewhat more catchy and dramatic on http://talk.sonyericsson.com/thread/22121?tstart=0 :P

Tomorrow more news are likely to come :):

"Well, I went into thephones4u store and told them of the issue with the static sound when video calling. I asked if they had another phone in store I could try out and when the sales person checked stock, she told me that they had been quarranteened and other branches had sent them back. She gave me a number for their main dept so I will ring them tomorrow so that they can elaborate as to why.

will post back as soon as i get more info."

I can promise the same as the guy in this post ;)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Super Chimp:
Does this mean there is likely to be a manufacturer recall of it?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
If this info is correct, there could still be at least two different explanation for this:

1. either SE initiated the process, starting to

2. or the dealer, facing considerable amount of replacements.

I'd bet for the second option at the moment, which is also a good turn of events, if many like this happens there'll be sure a solution, though the first would be the best.

If someone is from the UK, pls contact phones4u, and ask them ( I had chat with one very kind girl, though I didn't want to go on with calling a UK-line from here:) ):

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
A somewhat fresh take on (at least for me) on our favorite little issue:

"I think it is the battery what is making that noise, because phone is draining more power on that state. Same thing still occurs if I do neocore benchmark and while making that benchmark I can hear the buzz noise when I put ear next to the BACK COVER. While chargin phone there is absolutely no noise when making that same benchmark so I am pretty sure that's battery what's making that buzz."

Your opinion?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sipe1:
Battery could not be because it is eletrostatic noise. When you connect on charger, eletrostatic is grounded and there is no noise. There is problem in internal hardware, maybe it is short circuit, which is draining the battery. That buzz also can be cause of short battery life.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sur1k:
+1 to sipe1. If that was battery we would hear it with the screen off.

But there's one interesting thing: this sound persists during a call

when the screen is off

.

One more test:

I made two audio recordings using Virtual Recorder ('High quality recorder' as mentioned on Market; on X10 mini pro the records were amazingly good): with and without USB cable connected to charger.

What did I do? Here are the steps for each recording: Launch Virtual Recorder, start the recording, wait for several seconds, turn the screen off (you'll hear a click of a button), wait for several seconds, turn the screen on (another click), wait for several seconds, stop.

Here are the audio files:

Without USB: http://ubuntuone.com/p/1EkN/

With USB (connected to charger): http://ubuntuone.com/p/1EkO/

Summary:

there's no big difference in noise with the screen on or off. Maybe, with sleeping screen the sound becomes a little bit more quite (though the first record is absolutely silent at the moment of turning the screen off). Looks like that noise could be heard even when the screen is off. It's just not continuous, only several short sounds with silent intervals. You need to wait a little (no need to start audio recording). Or is it the problem progressing? By the way, the 'periodic soft clicks' that could be heard on the second (with USB) record are not caused by software. Turn off the screen, find a quite place and put the backside of your mini pro to your ear. It is very quite but it exists.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] jiminee:
Ok, lying on my bed with the reverse of the phone on my ear, I can hear a peristant ticking sound, slightly fast than 1 bpm. Its very quiet, but it is there. The electronic static noise is present with the ticking sound but intermittant.

With the phone still on my ear I press the power button and static sound becomes fairly continuous while the screen is lit, until my screen timeout turns the screen off again after 10 seconds. The ticking sound continues with intermittant static again.

I mainly aim to point out that on my phone, the static sound is intermittantly audible at all times, and is exagerated/continuous by illuminating the screen.

My guess is most people haven't noticed it because it's a quiet sound. The implications of that sound can be quite worrying though, poor circuitary... health risk :-/

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
The common problem must have linked us together! You'll see why:

Without reading your last posts the battery an idea came strongly to my mind, and I tested it. I took of the back, and examined the sound with camera app on. It really sounds like the battery (when back is on, the hole of the jack allows the sound to be heard easier), so when there's something more active is going on, it can be heard. It can't be the processor, because charging wouldn't cut the noise off.

Later, I thought how could I test that the performance is important, not the active screen (you see? ;) )? It's rare, when you use the phone heavily, but the screen is off...

But it came to my mind that I made my X10 MiniPro sweat, when I used a sport tracker with GPS, so I uploaded Endomondo, and switched GPS on for sat search, and turned off the screen with the power on/off button, and voila, a similarly strong noise can be heard.

Maybe my conclusion is inaccurate, but the noise is also there, when the screen is off and more the battery is used, the more intense the noise is and it's off, because the battery isn't used, when charging... (other option would be the processor, but I exclude it because of the silent charging).

so sorry Sipe, and Sur1k: -1 at the moment :D But it can also be a strange interference, it's not excluded.

Next question came, why in the standard Minis they don't have this problem, it's the same battery... but maybe they have, just it didn't turned out, as with better placed microphones the video didn't capture this... (we all noticed this phenomenon in the sample videos, and not by listening to the phone, even now I have to explain a lot to those, who have the noise).

And it would be the better for us that it's the battery, bec. then the problem again is a bit less serious, compared to an electrostatic short-circuit-like interference...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sur1k:
Well, maybe charging just make the device grounded, as mentioned above, so all the electrostatic (produced by processor / battery / anything else) goes out. Anyway, I don't feel myself experienced enough in this field to seriuosly discuss about it :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] BlackArty:
Maybe this noise depends on the CPU load/Cpu auto set frequency?

When I launch benchmark, CPU load set at 99%, but noise is disappearing.

Problem with CPU worse than problem with battery(

And I think that there isn't problem with battery work, because when system is starting phone works quiet.

U think that it will have this bug???

Thanks!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sur1k:
It could. We still don't have 100% approval that all of the devices are buggy (it could only be done by SE). Nor we have approval about which devices are bug-free.

If this noise is critical for you contact the seller before buying. Maybe it'll be possible to do some tests before sending the device (e.g. capture a video and share it with you).
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sipe1:
At least response in official talk forum. My theroy is this. Everything in cellphone has its eletronics. And eletronics is managing screen brightness and other things. My theroy that display eletronics is faulty, there is probably short circuit that is affecting other eletronics and causing drain of the battery. Just my opinion
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] jiminee:
Maybe we should have a sweepstake on the final outcome :-)

My bet's on grounding of the top mic/headphone jack circuitry.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sur1k:
:) I think, first of all, we shouldn't relax and think that the problem is solved. That answer actually doesn't mean anything. I'm not sure that it's so difficult to find the reason for company developers. Maybe they are trying to find the best solution. Maybe just waiting for people to calm down (which will mean no need in solutions at all). Etc.

On Russian forums most of the people say: 'this sound doesn't bother me'. That's the best solution for the manufacturer (it's the cheapest one). So if we want to get the problem solved we should continue collecting related info and sometimes asking questions in different sources: email, social networks, forums, comments etc.

The first post is updated with a step forward info from sxxorp.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
I've checked we have a very cool 1st post now :)

OK, guys, I didn't told you about the phones4u e-mail, and my contact to the local SE support, because I wait for definitive reply.

Sur1k, I'm totally with you, I feel the same, look at this, and I think all of you will enjoy and agree with this clip I posted to the SE-forum:

http://www.youtube.com/watch?v=SMVkUgQR9NQ

:cool:

Ignorant attitude... their choice, I respect it, but can't follow...

However, this idea comes into my mind more frequently:

"-Ok, so the bottom line is this, phones4u Exeter still had stock. I had another replacement which was week 29, and that one was just as bad. In the end carphonewarehouse changed it for the regular mini. A shame, because I miss the front camera for Skype. As a bonus though, the smaller size of the mini makes up a little.

-So you gave up...

-Given up in the way that I just cannot risk waiting for a solution that may/may not happen."

Confirmed good Manufacture Date numbers?

I also placed a comment on the SE official topic.

Since I bought the phone yesterday at a Phone House franchise I went back today (better to go now than wait for a SE solution). They said they were getting new Mini Pro's by Thursday so I can come by and try one of those out.

Are there any confirmed manufacture date pro's or doesn't it seem to be related 1:1 with the date?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] sxxorp:
Hi, thanks for contributing!

We have very limited info on faultless devices, maybe people don't notice this, or those who got a working phone doesn't care to share. I got only one video without the noise: 11W30...

And this one I don't accept as credible (I'm GGG) - you'll understand why :D:

In "how to check" section i would emphasize where exactly you should listen to on your phone and that it's a quite low noise in my opinion, although audible if you put your ear over the right place.

I've been looking for (but haven't found so far) an article I remember reading a long time ago on an audiophile (I think) forum where a guy removed the static noise made by his mp3 player (one of the early iRiver harddisk audio players if I recall correctly) by finding which chip was making the noise, and then applying a layer of something (I think nail varnish but it may have been something else entirely) on it.

If I find it back I'll let you know, but keep in mind that this type of mod may be a way to get rid of this sort of problem. Now we just need someone knowledgeable with electronics to tell us which chip is making the noise and what could be done about it ;)

To answer the first question you need to get a mini pro and check it (follow the instructions in the 1st post). Some people say that it doesn't bother them. For me it's annoying. But you need to make your own conclusion.:)

Hi all,

@Super-chimp: you take it to the service center, replace it, switch to sth else, or what?

I hope we don't get into the phase what dryhte mentioned with the nail varnish (though I wait for his findings on that topic, too).

I collected at our forum where I'm active on this topic:

1. in the official SE-forums started a thread with the most Views considering this topic

2. XDA: I'am the 2nd most active in the forum addressing the problem;)

3. I contacted SE support of US, exchanged several e-mails

4. I indicated this week by phone and e-mail the issue to the Hungarian SE-Support.

5. I try to find out the reason why the SK17i are quarantined by one vendor (confirmed by many British consumers), you still can not get it.

6. I typed here (I mean there), and to the Hungarian SE-blog

7. I'm one of the authors to a blog-post detailing all the problem we face with SK17i

(and I even don't mention the t-seria.hu, GSMArena forums, and Facebook) :)

huh, a little UPDATE- I just wanted to let you know I'm with you, but nothing is happening except from my thread receiving high view-numbers (I know you're part of it;) - keep on), WHEN I realized that got a less ordinary message! (I don't have time - Google translate from Hungarian, sorry):
