Hi,

No, making noise is definitely not a normal behaviour of lc-displays. My Neo does not (yet?) have that problem. That special part is faulty and there are chances that the sound will get louder and louder. That is how my palm tungsten behaved. It seems that history is repeating.

You are right, hearing gets weaker while people get older. But this has nothing to do with that special problem. My hearing is excellent and I could clearly hear the noise produced by the display of my tungsten, that started after three months. No noise yet with my Neo.

grettings,

Anyway, Google the problem and you'll see that lots and lots of people are asking why their screen whistles... Mine whistles, but only slightly. I think it is down to the screen and not a problem at all.

It's not just Windows phones...

And also this thread suggests it's the touch screen side of things.

You missed my point with regards to the drop off of hearing. I was pointing out that people lose their ability to hear such high pitched sounds as they get older. This could explain why one person on the forum says he can hear something and the next person cannot.

What is this 'special' thing you keep talking about.

[JAMin, XDA Neo, S200 General] exxi:
Here is the deal. I called the o2 XDA support hotline and I was told that this sound is produced by a faulty part in the display (some kind of transistor) and that if the sounds is hearable even if the device is not held close to the ear I should return it under warranty. In my case, i can hear the noise when I work at night and everything is quiet which is VERY annoying. I decided to return it and get an exchange unit.

Indeed, if I overclocked the device to 216 the noise would vanish eventually but I am not willing to have a constantly overclocked device or any kind of obligatory change. I can promise you that this noise is not standard for the neo because I testet it with more than 3 devices of friends.

I really hope that overclocking did not cause this harm else I will not overclock it anymore even though i really want it.
[JAMin, XDA Neo, S200 General] m444rcus:
I guess that all devices* cannot be faulty though....?

*all brands/phone etc that have a whine
[JAMin, XDA Neo, S200 General] Ahjetztja:
There may be many people that have this sound, but you can not draw a conclusion about the percentage. If you search for a problem, the results suggest that the problem is bigger than it is in fact. That is because people without that problem usually won't tell others in a forum.

Once again: you are right, but it's irrelevant. As I already mentionend, my hearing is excellent and I could hear the sound with my palm and some (not all) other PocketPCs. But as for my XDA Neo there is no sound.

According to my research it is likely to be a coil that is not well mounted. Have a look at this german posting concerning the palm:

[JAMin, XDA Neo, S200 General] m444rcus:
Where in that quote did I draw a percentage about how many people have that sound? I merely pointed out that there are many people who are questioning why their screen makes a noise.

You mention about people report problems far more than if there is none, I agree. But you need to take into account that people are asking the question across phone and phone platforms and about laptops. Therefore it is okay to assume that there some reason why these screen make a whine.

Granted your whine (your phone that is) may be greater than the one that I can hear when my ear is very close. The whine I hear is very high pitched and stops when I turn the screen off. It's not got louder, it's not changed due to over clocking and returning the speed to its original speed. Therefore are we infact hearing two different things? Who knows, just stop miss-quoting me and making out that you are correct. I am merely putting forward more evidence as to what the whine is and that it's not limited to these phones.

Still missing the point about the hearing bit and it

is

relevant as I was talking about everyone,

not

just you with super hearing (notice in my previous quote I said 'people' not you), marka2k said that they could not hear anything... so it may or may not be faluty or they might not be able to hear a high pitched sound anymore (sorry marka2k if you can :D )

As for the research (dont you mean you googled?), they would be in German... cannot be arsed to translate the page as I feel I must tell you again. I was only stating a fact that people are questioning why there screen on their product (phones, laptops, tv) make a whining noise!

If your phone is faulty, fix it or return it to the manufacturer or sell it, or throw it in the bin and buy another phone that does not whine.
[JAMin, XDA Neo, S200 General] victoradjei:
Happens on Atom too!

This is noise is a common problem on the Atom, and has been discussed without any solution except to return for replacement. Yet some find it on second and even third phones :twisted:

Are the phone manufacturers sourcing from the same place? What is the long-term effect on users? Nuking the brains :?: :P

[JAMin, XDA Neo, S200 General] Ahjetztja:
Here:

That sounds as if 100% of those display are producing this sound and one just has to live with it. I disagree with that conclusion. If it is not what you wanted to say then I am sorry for that misunderstanding.

No need to get offensive. Hearing is not relevant in this case, because there is at least one person that is able to hear such high-frequency-noises, that has got this device and that is not hearing any noise. This person is me. So the conclusion must be: This noise is not normal.

Sorry for that, I assumed you speak german or are at least willing to use babelfish. exxi wrote in the german forum that the official support told him: coil defective, please return device.

But you could have read that also in his/her post above:

No, if I want to say google, I simply do. Once again: No need to get offensive. Researching in this case meant looking through technical documents, opening a defective pocket-pc and examine the touchscreen (finding that coil) and at last using different programs to over- and underclock different devices that produces that sound.

What are you doing to get some light into this problem?

And the answer is: device is defective or has a cheap display/touchscreen built in. As for the palm there were two different touchscreen-manufactures. One type produced the noise (frequently) the other didn't.

My prophet DOES NOT produce that sound and I am very happy with this fact, as it obviously could produce it (like exxi's device does). But I have other devices that showed the same symptoms: palm tungsten (very loud), hp-pocketpc (medium). Devices of mine that don't produce any noise: palm 505, Dell pocket-pc, SDA II, IBM-Laptop and about half a dozen of flatscreens. This leads me to the conclusion: There are better displays in the world, there are cheaper ones and there are defective ones. And it has most probably nothing to do with overclocking.

[JAMin, XDA Neo, S200 General] moghisi101:
The screen can make this noise. A lot of electrical equipment with small LCD screens do. Even my Logitech Harmony 885 does!? It's not a big deal

That sound can caused by the overclocking. The processor or memory is most likely cause. It can happen in standard PCs as well.
[JAMin, XDA Neo, S200 General] m444rcus:
My God, how much of an arse are you Ahjetztja? You need to lighten up and not dissect everything that I write, it's really creepy. You know you could just accept that other people have different views and theories on things. Quote this, quote that, how anal is that? As moghisi101 says, a lot of electrical items with small screens make this noise. I can point you in the direction of a forum I read where there are pages of people discussing their large LCD TV screens that emit a high pitched whining noise... Sony ones, not cheap you know? (and all the people in that forum cannot have fault Sony screens)

The original post asked about a high pitched whine when put close to the ear when making a call. Other people here think it exists in every unit (exxi's post) I do too, the noise I hear cannot be heard unless the phone is up to the ear, which is what the original poster was talking about... If you know of some phones that emit a more annoying high pitched whine that is more audible from further away then fair enough.

Btw you miss quoted me again on your last post... stop doing that.

You asked what I was doing to shed some light onto the subject. Can you not read? (yes that's personal, when you get all creepy dissecting my posts like that) I've put forward many great :D ideas and links, where as you go straight in and state it must be due to a faulty part. Mine makes a noise, but after researching what it could be using Google I think it is operating just fine.

So in summary:

You're (Ahjetztja) getting creepy, please stop it

My phone makes a high pitched noise when held close to my ear but I don't think it's faulty

Other peoples phones make this noise when held close to their ear

England to win the world cup (well we can dream :D)

You (Ahjetztja) like misquoting me

If it's faulty, do something about it or find out which phones are prone to making this noise and don't buy those ones

Take Ahjetztja's conclusion by not buying a phone that has a cheap screen that emits a high pitched noise, in fact buy the same phone as him

Don't use Babe fish, use Google page translator, it's great

So exxi, enough of that cr@p, is the sound only audible when the phone is held close to your ear like mine?
[JAMin, XDA Neo, S200 General] fluffcat1:
Caused by the backlight?

Hello,

I and others have this problems on ( some) magicians. I don't have a prophet yet to tell, but my noise goes away if I turn the backlight off with the screen still on with the magician screen that does this. Changing the screen causes the sound to dissappear. I do not think it is a voltage invertor issue with the backlight as most recent HTC devices use low voltage illumination, but it would seem for me with 1 magician the screen is the root cause.

There would appear to be two different LCM possible in the Prophet. Perhaps people can take part in this poll and comment whether they have the noise or not?

http://www.modaco.com/index.php?showtopic=241120&hl=

It might be interesting to see if there is any correlation.

[JAMin, XDA Neo, S200 General] dimushor:
so you guys are saying that overclocking would solve this? for instance, when i overclocked my wizard, i remember exactly that it was making that noise. so, probably this is not the solution :shock:
[JAMin, XDA Neo, S200 General] exxi:
The overclocking indeed works, If you clock it to 216 for example the noise vanishes completely. To answer the other question about if the noise is only audible if held close to the hear.

The noise is clearly audible at close range to the ear and also from a distance of up to 10 centimeters. I decided to return the phone for an exchange which was confirmed by o2 as a legit reason to claim substitution.

If the noise is really weak you should keep the device in my opinion but if it starts annoying you, return, wait no longer.

If you underclock the device the noise changes into a darker one.
[JAMin, XDA Neo, S200 General] khendar:
I dont know if this is relevant, but this ocurrence is often associated with failed or failing electronic components, commonly is capacitors. When they start to fail, as was the case in many PC motherboards a couple of years ago, they start to whine and bulge at the top. Eventually they split and spit out electrolytic fluid.

Not sure whether this is what is happening in these devices, but might be worth looking into.
[JAMin, XDA Neo, S200 General] exxi:
any more ideas?? i have a new device now and the sound is NOT there, i am sure of that.

I really want to overclock again but I am scared, any advice ??
[JAMin, XDA Neo, S200 General] bloney:
I believe the backlight needs a high voltage supply and the invertor circuit used to generate the high voltage uses inductors which will vibrate to an extent. Perhaps a derivative of the clock is used for the switch mode supply and ths is why a change in clock frequency could cause/cure the problem.

Hope this helps

[JAMin, XDA Neo, S200 General] Ahjetztja:
So it seems that noise is not normal for those displays. Please have a look at:

http://www.modaco.com/index.php?showtopic=241036

and tell us, what your display looks like. There are at least two types of display built in the prophet as the link above shows clearly. Maybe there is a connection between the type of display and the tendency to make noise.

What is your problem? You did succeed in returning your first device as faulty, why would the shop refuse to take it back a second time? So my advice is: overclock and be happy.

If you do want to find out what is going on, then instead you better do not overclock. Just please wait and see if the noise comes up. In this case you will know that overclocking has nothing to do with the noise. The downside is that if the display will stay calm for ever, then you are not wiser than now.

[JAMin, XDA Neo, S200 General] dimushor:

[JAMin, XDA Neo, S200 General] Ahjetztja:
I totally agree with you, that is my state of knowledge too. But as fluffcat1 says:

Maybe there is an electronic technician who could tell us more. So that all the people with noisy devices will get a solid reason to bring them back to the shop as being faulty.

greetings,

Ahjetztja
[JAMin, XDA Neo, S200 General] Ahjetztja:
Hi,

@dimushor

exxi stated that in his/her case overclocking calmed the device. Your experiences fit perfectly in my theory that the noise is a problem of a faulty part that gets in resonance with the case. There is no fixed frequency that "causes" those resonances. It may be the standard 185 MHz, it may be a higher or lower frequency. So some people will experience that overclocking is a problem, while for others it is the cure.

What happens if you underclock your device?

greetings,

Ahjetztja
[JAMin, XDA Neo, S200 General] dimushor:
i don't want ro underclock my device. :-) probably i have to live with this noise
[JAMin, XDA Neo, S200 General] exxi:
in my case underclocking made the noise even louder of the time being.
[JAMin, XDA Neo, S200 General] zaitsman:
Hey, my I-mate JAMin doesn't have any sound. However, i used to have it on Roverpc S2(Lenovo Et560 or 960 - the big PHONE looking one) when i had that one a couple of years ago. It's probably faulty screen.

[Sony Xperia M2] andyxoxo:
Thanks for the news, highly appreciated.

Quite a jump in screen size, for me it shouldn't even be called the M2 anymore as that new screen size moves it easily into Xperia C territory (C Mini? haha). I think my next phone will be the Z1 Compact with the 4.3" screen. That's about as big as I want to go
[Sony Xperia M2] Dr Goodvibes:
My thoughts too.
[Sony Xperia M2] Antrikos48:
Exactly. Why can't they make phones with screens less than 4.5 inches

[Sony Xperia M2] mbc07:
Well, it's becoming hard to find Xperia devices at the 4" screen size range :rolleyes:

I really liked the Xperia M2, but the bigger screen is a no go for me, will stick with my Xperia M dual until I find something better... The Z1 compact would be perfect for me if it had dual SIM variant, but flagship phones never get dual SIM versions, I'm out of luck
[Sony Xperia M2] mindyabiznis:
:good: well done Sony ... what a waste of time!? and yeah I'm also getting sick of these screen sizes slowly teetering their way to the 5" mark :mad:

Would be good if they sorted out support for customisation of the current M instead of making a new one less than 9 months of the release of the original... buuut I suppose that doesn't make money does it? ;)

As everyone else has said, looks like the z1 compact for me at the end of May although a bit disgruntled about the 4.3" screen and the reports of the music output being nothing short of rubbish when played on anything other than the Walkman app :eek:
[Sony Xperia M2] Dr Goodvibes:
I guess the smart money is now to do nothing and enjoy our XPERIA M as we progress through the forth coming Android upgrades distributed by Sony.

If you bought the XPERIA M for the right reasons, it's still a really good phone and from what I read above, even better than the XPERIA M2 regarding size/weight.

Weak points are 5MP camera and 2GB storage, which can be worked around with a bit of effort.

Speaking of smart money, Qualcomm is releasing a raft of 64bit chipsets such as the Snapdragon 410, Snapdragon 610 and etc..

There are RUMORS Android will become 64bit with strong indicators pointing to the end of this year and beginning 2015.

So buying a new 2014 32bit Android phone may have even less upgradablility than usual when the revolution comes and "everything" goes 64bit.

Of course the above is moot if you buy a new phone every 6 months to a year.

I'm still using a Sony XPERIA S (circa 2012), so you can see where I'm coming from.

An XPERIA Z1 Compact may only be a 6 month to 1 year stocking filler technology wise, if 64bit phones become available...

That said, the XPERIA Z1 Compact would provide good service for some years for most people even if it's support didn't go much beyond Android 4.4.2. You'd still have a very optimised Android OS, ART and all the current core deliverables.

Then with your XPERIA Z1 Compact, you can sit back and wait to see what 64bit Android provides when the technology becomes more mature and widely available.

The other thing is that the older phones at competitive prices like the XPERIA ZR, XPERIA V and XPERIA SP all become attractive if Sony is going to pander to larger screen/sized phones over the next few months.

Would have bought the XPERIA SP over the XPERIA M, however, the 115g in weight was just to attractive compared to 155g. :D

It is my mothers purple XPERIA M after all.

I was previously on the original HBOOT (first one) and S-Off.

I did NOT have the "TAMPERED" flag on my phone.

After upgrading to latest release I am on the latest HBOOT but now it's also flagged as "TAMPERED".

My understanding is being S-off a way to remove this should exists.

I've never done the HTC unlock as have always been S-Off.

Is it possible to get this removed on latest release without being 100% stock?

I know on some phones like the One you can modify a flag in one of the partitions.

I am on a stock rom just rooted so beyond seeing that flag it's not obvious I am rooted.

A: Just ignore it. It's no big deal.

Someone did a mod to remove the developer text but that's it. My understanding is the flag doesn't reside in the HBOOT directly but in some other area of the phone?
[Sprint HTC EVO 4G LTE] AarSyl:
Run a RUU. It will remove the *TAMPERED* status. Your phone will remain unlocked, and it be displayed as such.

If you don't have easy access to a PC, one of the easiest solutions is to download the VipeRUU zip to your phone, extract the rom.zip to your ext SD, rename it to PJ75IMG.zip, and flash it through the bootloader. The next time that you reboot into the bootloader after the process is completed, then TAMPERED should be gone.

I'm just speculating, but maybe you removed the tampered status before by using the Regaw Bootloader Customizer, which only edits the bootloader info, and doesn't actually change anything for the phone itself. It's only a cosmetic change.
[Sprint HTC EVO 4G LTE] SilverZero:
That's what I did - noticed after the 4.3 RUU that it went from "Unlocked/Tampered" to just "Unlocked." I kinda want to also modify the "Unlocked" text as I did before with Regaw's tool, I'll have to look into whether it will work.
[Sprint HTC EVO 4G LTE] AarSyl:
There's a reason why I didn't suggest using that tool. You kinda need to MAKE SURE that you know your bootloader status. If you activate S-On twice in a row, that baby's definitely gonna brick. I rather know what my bootloader is supposed to say, because I'm really the only person looking at it. What difference will it really make?
[Sprint HTC EVO 4G LTE] SilverZero:
Well that's why I said I'd have to look into it. I assumed it wouldn't work with the new HBOOT, and I guess I don't care one way or the other. But for anybody else reading this, don't try it.

On the other hand, I climb mountains because they're there. If I want it to say "Hacked" instead of "Unlocked" and I can do it without screwing things up, I might do it just to screw with the guy who buys it from me down the road.

EDIT: This post is what I mean. You have to understand what the Bootloader Customizer actually does (which is explained in the thread) and know that flashing this would bork all the things. This is literally a 2.09 HBOOT. The 2.10 HBOOT is what accommodates the new partition layout, so flashing this will break that and prevent the device from booting up. The issue is the signed boot.img. That's why you see the tampered flag. I assume you're not using my stock rooted? You updated directly from RUU, and then rooted it manually? The signed boot.img sees unsigned recovery img and throws up that tampered flag. It's not going to affect the working of the device, so why worry about it? You can flash the boot image from my stock rooted if you want it to go away.
