As soon as torch is activated the phone makes a constant crackle (like static) sound which seems to originate near the top of the phone. If i put my ear up close under the static sound I can hear a second sound, quieter more like a motor spinning hum.
Any ideas?? I need to replace the screen so I need to open it but any suggestions as to what it is or what I am looking for?
Having just put my ear on the back of the phone it could even be coming from the middle of the phone but the top speaker area is noisy and bottom speaker area is quiet so......i'm confused as they are the same distance away.
I am flummoxed
I haven't heard of this problem specifically. But your description sounds like it might be capacitor hum/crackle. When a capacitor goes bad, it tends to make a hum or crackle. And not too many other electronic components make a "noise" when they fail. I also don't know if this is anything you can replace, without replacing the whole board. But maybe that give you a starting point, when you open up the phone. Good luck!

Heyhey,
When i am calling, and put on my over 50% my speaker starts acting wierd (the one that you hold at your ear). It sounds like it cant handle the sound comming out, like its to loud or like there is something wrong with my speaker.
Known problem with the hero and speaker?
i notice the same thing with mine. it sounds like the speaker taps out... almost as if its going to blow. i'm assuming this is a common issue.
anyone else get root on and now people complain about sounding muffled?
I am considering factory resetting and testing before i return for an exchange...anyone confirm or deny this on their unit?
Make sure you unroot before doing a factory reset just to be safe.
Rooting shouldn't really affect anything.
I'll put myself on Deny.
Check the noise suppression option in call settings.
Yea, you should check the noise suppression. Also note that the microphone port is on the face of the phone, not the bottom.
Rooted/ROM Captivate (For Sale)
Rooted Atrix
not sure if it happened after i rooted but everyone is telling me and my friend who has the atrix also that we sound muffled. I rooted the phones about 5 minutes after getting them so i am not sure if it sounded fine before hand
It actually might be due to the rooting; but I tried calling my GF today and she couldn't hear me at all. Be sure to turn noise suppression to normal or off.
So i been doing some test. And what i seem to find is that since that little slit in the front bottom is the mic it works best only when its in front of my mouth. It must be a very directional microphone
Just for reference:
ROOT HAS NOTHING TO DO WITH IT.
Claiming Root as the possible problem doesn't even make sense. It's like saying your car's running poorly because you replaced the hot water tank in your house.
The cause of the "muffled voice" problem is 2 things: The microphone is fairly directional and it's actually on the front of the phone. What this means is if it's not pointed toward your mouth it won't catch the sound very well. This only applies to people that have the phone way behind their mouth (most people since we've all grown accustomed to holding that phone that way). The other culprit is Noise Suppression. Since your voice isn't coming through much louder than the rest of the environment the noise suppression system is trying to minimize the sound of it (it thinks your voice is background noise). In doing so it makes your voice very quiet and "muffled".
Just noticed an odd very light whirring noise from my headphones when they are plugged into the Evo 3d and the screen is updating.
For example when i turn the screen on and the weather animation on my lock-screen runs, it makes the whirring noise, but when I am on a static home screen it is quiet, but then if i swipe to move to the next screen i hear the light noise again. Same if click on the launcher button to open the app drawer, or click on the phone button on the screen and it opens the dialer.
Wondering if this is a common issue/bug, or if I have a defective unit i need to exchange.
The headphones work perfectly fine in my old phone so it isn't the headphones.

I had headphones on for about 40 minutes yesterday morning and didn't notice anything like that at all. Have you tried a different set of headphones?....just to pinpoint in fact that it's a problem with your phone.
I see what you are talking about. The noise is really faint, but I'd say not to worry about it since it may be software related. When browsing apps and what not the sound is gone.

Damn......just put my headphones on again and still nothing like that. Either my phone's not afflicted or my ears are worse then I thought after to many years working in a factory.
I can hear it too, when I scroll I can clearly hear it. This isn't anything new, I've noticed this sort of thing from other devices. Certain laptops will make a tiny squeal when rapidly scrolling something on the screen with the volume jacked up. We're probably hearing added EMI from the increase in CPU activity. Not much you can do about it. :/
The original Evo used to always make this annoying warbling noise during silence. At times it honestly sounded like faint music almost, it was that pronounced.

Yep, that's a fact of life, when it comes to electronic devices. When it puts out enough power, it'll interfere with the headphones (Which, if you think about it, headphones are just a giant magnifier for electronic pulses. Makes sense)
If you don't believe me, hook up an aux cable to your car stereo, and pinch the end. It'll make a buzzing noise. You're electrically charged enough to play music!
Same thing for the internals of your phone. Doesn't take much. Heck, you could probably set your phone next to an MP3 player that you have your headphones plugged into, and still get some interference.
Thanks for confirming that you can hear it too.
I know what you all are saying about electronics having some EMI, but i went back and compared it to my original Evo, and a friend's iPhone 3GS, and neither of the two gave any background noise because the screen was changing/scrolling etc.
Gotta decide if I want to return it. I love the phone's speed, features etc., and this is definitely a minor thing I am bringing up, but it just bugs me a little.
I also have this noise problem, noticed it right away. I also have a slight cracking sound from the speaker when a loud sound plays. It's odd because normally other devices are able to be placed at max volume without hearing distortion. I'm not ready to return it yet, my roomate got one this morning, and I want to see if his does the same.
My Evo did the same thing, especially worse when I had it plugged in.
Same effect on my phone. I just noticed
last night and thought I was hearing things.
I noticed this right away on my 3D. I never noticed any similar sound on my EVO 4G.
Thankfully, it seems to disappear when I am not interacting with the phone. Therefore, it's not a huge issue for me.
As title says. I hear a strange high pitch noise coming from the back of the phone. I have a bell c6806 with android 4.2. it's always making the noise and I hear it when I'm on a call. Very annoing. Is this normal? Can anybody check theirs by placing an ear on the back of the phone near the camera. any info on this be really helpful. Thanks. Also there's another less noticeable sound that sounds like the noise that comes from a mechanical hard drive :s
Update. I turn my phone off and on and the noise go away. But as soon as I make a call the high pitch squeal sound comes back. I thought it was first coming from the ear piece first when I heard it but it's definitely from the top back off the phone and it doesn't go away the sound stays there until I turn the phone off
Haha! What the... I have never noticed it, but you're right. It does make some sort of noise! I know what it is though; it's the radio (antenna). Not sure why it makes a noise and i'm not sure if other devices have this noise, but it's the antenna. It'll go away as soon as you kick it into Airplane Mode. I have to really listen for it when i hold the back side to my ear, so i can't say it bothers me, but it's definitely a little strange
EDIT: Some more information around these "chirps". I'm going to listen to some other phones i have laying around now and report back soon.
EDIT 2: I checked an LG phone (can't remember the model), but it also makes some noises. My old Desire HD doesn't, but it doesn't have a SIM in it, so that's probably why. I'll check my Galaxy Note later today. It's totally logic though. Our devices are constantly connected to cell towers, so the antennas are always pinging the towers. It doesn't make the same noise if i'm in airplane mode with WiFi on. It's much lower, and i guess it's because of the frequency.
EDIT 3: LOL
EDIT 4: I contacted Sony and they are not aware of this, so they can't really say if it's normal or not. But as long as the device is fully functional and there aren't any issues, we shouldn't really be worried. But if you are worried, you can send it in and they'll take a look at it (not sure if it's worth it to be honest).
This one is on a whole different level
Thanks for checking yours. Do you hear the high pitch squeal tho? I've actually tried to to change network modes 2g 3g lte and also airplane mode but it doesmake a difference for me. The mechanical noise is pretty much always there but I don't hear it unless my ears are press to the phone but the noise that bothers me is the squealig because I can hear it when in a phone call do you hear both them noises on yours or just the mechanical sounding noise? I'm going to try and record it tomorrow after work.

I made a new thread about this in the general section since i wanted more people to see it. We aren't the only ones with this "noise", and it's also on other devices too, so i guess it's pretty normal. I still don't know why the antenna makes noises though.
Unlocked my white 32GB after 300 MB download. No issues.
Installed a few apps, nothing special yet, no system related apps.
This afternoon my N9 started ticking from the bottom speaker each time I touch the glass. Just unlocking via pattern does it also.
About 12-15 very quick clicks like a speaker wire is shortening out.
Any hope before I call in a RMA?

How loud are these clicks?
It isn't unusual to get quiet clicks and buzzes when using a device, the Nexus 4 for example is a famous for it, it constantly makes a noise if you put your ear to it even when it is sleeping.
The CPU and other components are awake shy. They spend a large amount of time in sleep mode, perhaps coming on for a millilsecond then going off for several milliseconds, then back on at the next touch where it needs to display a nice graphic or do something, then off again. Everytime the CPU switches on, so does a lot of electrical circuitry to drive the power requirements. Currents switching on and off flowing through wires creates noise, either audible directly, like the hum from a kettle or a buzz from a power supply, or via electrical noise that is picked up by other circuits, for example the amplifier for the sound, which then makes it audible. Almost every electronic device if you put your ear to it makes a noise and buzzes, often changing in tone when you make it do something.
So I would say if it is very quiet, only audible in a quiet room when near to the tablet, it's is probably just normal operating noise. You might find a replacement is quieter, or you may find it is louder. You may find someone else can't hear it at all, if you are young you are more likely to hear these things than someone who is older as we lose high frequency hearing as we get older, and listening to loud music in headphones makes it happen quicker
Of course if it is pretty loud, audible all the time and annoying, certainly go for a replacement.

Just wanna make sure, but you are not talking about the button touch sound on Android 5.0 are you? The sound has been changed to a very swooshing sound that almost sounds like static on an audio line.
Thank you guys for your input.
The sounds I observed were loud, not the near silent hum kind. More like a finger nail is hitting a window.
The sound got progressively louder during my trouble shooting.
It ended up in a total distorted, muffled tone coming from the bottom speaker.
Something inside shortened out.
I had a micro-Tesla conductivity meter this morning at my bench and I could see that by touching the screen even at the top it induced a small current directly at the bottom speaker.
I called an RMA and the N9 was declared DOA.
Replacement is in the mail.

When you called what did you tell them? Where did you get it from? I got mine from best buy, and have this same problem. I think I'm going to wait until its closer to my 14 day period... Maybe I'll get a second batch device.

Not me. The ticking sound was the first thing I listened for when was testing out the speakers. I didn't hear anything out of the ordinary.
Took me awhile to be sure though cuz the song i used to test actually did have occasional ticks in it. I had to relisten to it on my headphones and on my home theather system to be sure it was just the song and it was.

I told them just my findings. Repeated click sounds by touching screen from a single speaker. This was a direct Google order and they sent a replacement within 24 h's. No questions asked.
The new White N9 is perfect. No unusual click sounds. In addition to that, there is a little less light bleed and from the few hours I used it so far I get the feeling that the battery is lasting a good bit longer. The first N9 went from 100% to about 40% within 3 h's of trouble shooting, the replacement is still at 75% after I unlocked & rooted and put back all my files, about 2.5 h#s screen-on-time. Makes sense, since the constant shortening out the speaker uses electricity.
The serial number difference of the last 4 numbers is a 44 higher count number, so I believe its the same batch/lot.
Overall, a quick and painless exchange and Google's RMA process is one of the fastest and easiest I have gone through.
