I've had my AT&T banded N1 (with Rogers in Canada) for nearly 2 weeks now and I've been waiting to make sure everything works properly before I potentially give up my warranty by unlocking it. One thing that has been bugging me though is the call quality.
Everyone raves about how clear the call quality is on these things, but based on my phone I don't really agree. When no one is talking the line is dead silent (so silent that I almost think that the call has dropped), but when the other person begins to talk a light static or crackling background noise starts and once they finish talking it goes away and is completely silent again. If the static was there all the time I might not even notice it, but since it stops and starts during pauses in the conversation it really stands out. This happens on both the handset ear piece and with the headphones that came with the phone.
Has anyone else noticed this? If it's normal so be it, but if not then I might as well try and get it fixed before I do anything.
I don't have the at&t version but that does not sound normal.
Crackling is normally a sign of a speaker problem but I wouldn't think the headphones would also produce it.
seems i have the same issue...
i havent noticed any noise like this, but i will go test it and see if i have it too.
It's the speaker, for some reason the Nexus One comes with a slightly-too-loud speaker volume setting built in and you need to turn the incall volume down one notch from max. At least that solved my problem, hope this works for you!
have just called Google Tech Support and the guy suggested me to blow into the earphone couple of times and see if it helps
if not, do a hard reset
if not, call for warranty...
Since I get this noise in both the handset and ear phone speakers at all volumes I have to assume the problem is with my radio.
It's too much of a pain to get warranty work done outside of the US so I'm just going to learn to ignore it.
Hi guys,
i think there's a problem in my i9000;
whenever i make a call, i can hear low static interference in the background.
i searched both on xda and elsewhere, and although some other people complained of this problem, no one was able to determine the cause or provide a solution.
i tried different roms, froyo and gingerbread samsung roms, in addition to cm7, with different kernels and modems, heck i even changed my csc(just for sake of changing everything to make sure.. all for nothing. the problem persists.
Does anyone know what might cause such problem and how it may be solved?
i have exactly the same problem. Like you; i tried every combination which i can. I think main cause of the problem is hardware related. But my opinion is ,it can be fixed with device drivers. I looked at service manual. In the speaker part of the service manual,you can see there are two inductors and one capacitor before the speaker module. You can see the full circuit in Service Manual Page 42.
h**p://img191.imageshack.us/img191/2383/speakerj.jpg
I think these inductors(L209,L210) are interferencing with the GSM frequencies and making that static sounds on the background.
We need someone who is an expert on linux and device drivers. Maybe he can show us to find a way to break this circuit(temporarily turn off B1 and A2 pins) in a call so it will not make that sounds.
In the other hand we may have defect phones. May be the only way is to change some parts.
sorry for my bad english.
I think there's something wrong with the speaker itself.
I'm taking the phone to samsung's maintenance to see what they have to say about it.
I'll report back once i get to the bottom of this..
Same here, but it's not constant, just happens enough to be noticable, bloody annoying, and only started (or I only noticed it) a couple of days after JVP. Will be interesting to see what you find out...
One possibility, do you have your phone in a magnetic flip case? Worth checking

No magnetic flip case, just a hybrid (plastic back+sillicon frame) cover.
I even took it off for a while to see if it was causing the problem, but no.
I went to samsung service center and they said it will cost about 200$ because the ear piece comes with the touchscreen..
Meaning i would have to pay for a new touchscreen even though i only need the ear piece.. How about that for service.
I checked ebay and found the whole ear piece+speakerphone+headphone jack in one bundle for 15$
so guess what my next step will be??
Buy and install the ebay part, sell my i9000(never liked tw anyway+cm seems a long way from home).. Had enough samsung for one lifetime
are you sure about the sound is coming from the earpiece ? i am asking because few weeks ago i was also assuming that the interference sound is coming from the earpiece . But i realized that it is coming from the rear speaker. Can you test it ?. In a call ,turn back the phone and put speaker hole to your ear. The interference sound is so loud that you can hear it from the earpiece hole.

This is the question which i am also looking for answers
Everyday i am searching for answers. Only a very few people experiencing this problem.
I think this problem is coming from the inductors in the speaker circuit part. You can look my first post .

i have this problem too, i live in Romania, i tough my phone was broken, but a friend's phone also does that.
i notice it when making call while 3G data was running in the background. If 3g is off = no noise.
Also i have noticed, the way you hold the phone affects it. try holding it with 3 fingers to your head the covering the mic hole with the other. you should hear some interference right there. so it's probably: speaker+ extra sensitive mic + some antenna things
Also my friend had the phone for some months now and never noticed it i searched the web and we're not alone, i found this discussion on a couple of other forums, still nothing to do, or nobody reported back after they whet to the warranty service. i would go, but i don't have any warranty on mine.
I'm also from Romania and I noticed this annoying issue today. All my other friend with Galaxy S also have this problem, so I guess it's a normal thing.
The only solution, I guess, is to use 3G networks, at the risk of draining a bit more battery.
so bottom line is that on mine, i hear noise/buzzing/interference when i use 3g networks both on the speaker on the back and the earpiece (it's louder if i use 3g data while i'm making a call) - the issues goes away completely in gms(2 g) mode
and it depend on how i'm holding it - it's louder if i grip the phone in my hand (probably the wireless signal is lower and the phone increases the power needed to communicate to the network thus experiencing buzzing sound from the speakers like radios did back with the first cell phones before receiving a call)
so i guess i'm not the only one, right?
This issue is normal I think. No big deal. If the noise however gets so loud that it interferes with your call, get it changed. But the new ones you get might have the noises too. So what is important here is to keep the noise to the minimum.
With / Without the noise is totally an unknown cause now. At least have it settled to the least noisy.
*This is happening to everyone who is getting the phone since November 2010
I confirm this issue with more models.
Hi guys!
Bought myself my GT-S5570 (Galaxy Mini) a couple of months ago. This is my first Android experience. At first I was pleased, but then I noticed this static noise whilst in call. It's like, suddenly I can have ill-isch, distorted, "noise spikes" sort of things. Left my phone in for service under warranty. When I had it back, it was still messy. Bought myself a GT-5660 (Galaxy Gio) a week ago, thinking that this one would clear the issue. It's still there, though. I'm wondering if this is something that affects the whole Galaxy series, even the tougher models like S/S2.
Related threads, by me:
android.net/forum/samsung-galaxy-mini/60951-sudden-volume-spike-during-call.html
androidforums.com/samsung-galaxy-s/307523-samsung-galaxy-s-gt-i9000-static-ear.html
yesterday my cousin bought i9000 too. First of all i looked for the noise. It is interesting that that phone is nearly noise free. If i gave 10 point noise to my i9000 than that phone will be 2 points. You can hardly hear the noise. After that i get her SIM card and test my phone with that sim card.Noise is still there.I make that phone software same with my phone. That phone still has no noise.
I think the problem is in phone parts. Maybe a defected series of speakers used in our phones. I will buy a new speaker module on internet. I hope that fix my problem.
For me it depends more of the network I use than the phone. It happens sometime with an iPhone.
as i stated in my previous post in this thread, in my case i was sure it was the loud-speaker, i say "was" because i sold the phone, and thats the reason why i didn't come back to this thread since..
it seems there was something wrong with the loudspeaker(on the back of the phone), and it was, at least to me, one of those things where a person might not really notice unless you're looking for it.. my bad luck had caused me to flash a certain modem and the reception was bad, so once i reverted to the previous modem i was checking for the sound clarity and that was when i first noticed the static during calls..
then i realized it was coming from the speaker, as one good man in this thread suggested. i couldn't handle it though, i could hear it every time i make a call..
it didn't make a difference whether i was on 3g or gsm or both, it was always there, unless i went into airplane mode..
so i ended up selling the phone, and bought another, but before i had bought it i put my sim inside and made sure there was no static, and there isn't, whatsoever.. thank god.
i'm sorry i couldn't find any other solution to the problem, samsung service here had said they would replace the speaker, as the part comes on its own, unlike the case for the phone speaker, which, according to samsung, is bundled with the screen, and if i had wanted to change it i would have had to pay something like 200$ to fix...
those who have this problem, check if its the loudspeaker on the back of the phone is the actual culprit, and if it is, try to find a way to replace it or something, that is if it bothers you this much. or you can just sell the phone, there's a 99% chance those who buy it won't notice anything, because they're not looking for it..
good luck guys..
Upon receiving my second HTC one today (I RMA'ed the first one due to quality control issues discussed here: https://www.youtube.com/watch?v=NwOu5oXpjVQ ) I find that this one have something loose inside of it, somewhere around the area of the upper speaker or the camera (camera works I've checked it). And it makes this Rattling/buzzing noise every single time a put the phone in my left palm (or by lightly tapping the upper part of the phone), quite annoying after awhile... It's not from a loose power button nor the volume keys. I also tried pulling out the simcard tray as well, and the noise persists.
I never noticed this on the first phone. Are you experiencing any of this? This can't be normal, right?
Hey, a simple no answer would be good if you're not.
Thanks.
(Added poll)
No not for me. If anything, its probably the camera for you thats "loose". It happens with a lot of phones
I'm having a buzzing vibration from the top speaker when playing sound through the speakers (music, video, etc. but not during call). Definitely something vibrating under the speaker grill with the sound waves of the speaker, particularly at the frequency of a male voice talking. I'm about to contact HTC for a return. Very frustrating because the rest of my phone works great. Now I'm worried about getting a refurbished unit with other problems...

Got mine RMA'ed, second time now. I haven't received a refurbished unit as of yet.. But I'm not in the US and rma's are handled a little different (we do it through the retailer as long as there is any warranty left). Got a new device last time, and I'm expecting that is what I will be getting this time also.
Does anyone else have a slight crackle noticeable at high volume while playing songs or loud noises? Its a slight crackle and you can tell the sound is not as pure as it should be. Put a song on YouTube full blast and see if you can notice any little crackle, you might notice sound is not butter smooth....
I have a crackle on the bottom speaker with the stock ringtone. i posted about it on here, but noone responded
I have the same issue with the volume is all the way up. But if I lower the volume a little it's good. This phone is crazy loud
a software update can fix that.........

If it does it will just limit the max volume.
Yea it sounds like a software blip actually. The sound isnt like a rattle from an unseated or blown speaker its strange. I wonder why no one else hasnt brought this up...
I had issues the first day but none recently... Maybe they just need to break in
Yea if i blownin the top speaker while its playing it crackles loke crazy. Not that you shoukd do that. I did very lightly. The bottom speaker does not. Might have to rma.
Happens in top speaker for me as well. I notice it particularly well with the second half of the ringtone/notification sound, "Ganymede." Should we ask for a replacement?

This has to be an audio bug. I have also noticed it on my ATT Model. I have also noticed that the ringer volume drops dramatically when receiving calls. It is also hard to hear the person on the other unless the phone is held close to the ear.
Been having the same issue. It seems to mainly happen at the beginning of some notification sounds, almost like it has trouble initializing the sound on command.
I noticed this when I was playing a game, after muting all sounds, it sounds like the speaker is still active and produces noise. Its more of a hum than a crackle, for me at least. I I'm pretty sure its a software issue and not a hardware.

With regards to the popping/crackling/buzzing that I posted earlier in this thread (I think on the last page to be exact; also this may be different from what you're describing), I have confirmed via a replacement device that I just received today that it was a hardware defect, NOT a software defect. There is no popping/crackling/buzzing or anything like that with the new one, and I even held them side by side and did a comparison for another person just to make sure I'm not crazy haha (though it was pretty apparent when the new one didn't exhibit the problem I was hearing with the first one). On a side note, the screen on the new one looks like it has better whites (I didn't have a problem with the other screen, and it looked just fine to me, but side by side you can see a difference and I guess I got a two for one on this by doing the exchange!)
And finally, I didn't have to update the replacement out of the box like I did the first phone, which means they're now shipping phones that already have the latest update applied to them. Just thought I'd check back to let you all know that if you do have this issue, you SHOULD RMA/exchange it for a new one, because it is NOT a software glitch if you have the same issues that I described previously.
Hope this helps =]

Yes it does help, thanks! Im going to rma mine monday and post back with my results also.
I first noticed a problem with my speakers when I made my first call. My nexus 5 always had great call quality but my friend sounded so hollow and not at all as clear as on the 5.
Then I tried sounds, music. It definitely has a noticeable 'peak' and high and low notes flatten and rattle. Is this what you all are experiencing?
Sent from my Nexus 6
Anyone noticing issues with WhatsApp? I can't seem to hear the conversation tone while I'm chatting. The notification rings just fine, it's just the conversation tone. I've factory reset, but made no difference. Any help will be appreciated.
hey all, i definitely have crackle on the bottom speaker. i do not have any issues with the top. I hear it with notifications as well as music. Here is a good test YouTube video that i am using to see if anyone can compare. I have to hit the vol rocker down 7 times from full volume to get crackling to go away.
I've contacted Google (i purchased through Google Play Store) and they are shipping out a replacement saying this should not happen.
Here are the steps they had me take to test the device.
1) make sure Bluetooth was off
2) check the volume settings for all types of notifications (ringtone, alerts, alarm...)
3) reboot into safe mode and see if it still persists
---> to boot into safe mode, hold the power button like u are going to turn the phone off, when the "Power off" option pops up on screen, long press it and it will ask if you;d like to boot into safe mode. THIS ONLY LETS STOCK APPS TO RUN, thats why i used youtube for the example.
4) factory reset(they asked how i did it, i did it normally through the system settings)
After this, the rep explained that this was the first time she heard of the issue and the replacement device shouldn't have any speaker issues.
I also asked if it will be a new device and she said yes, no refurbishes. If the issue happens again, she mentioned to call back in and they will replace it no problem. Hopefully this first replacement won't have the same problem, but i love the phone so much that im willing to have them ship multiple out until i get a good one.
hope this helps!!
EDIT: forgot to mention, they put a hold on your credit card for up to 7 days until they receive the device back. You SHOULD choose next day shipping as that will be part of the hold and your card will NOT get charged for any extra shipping charges.
Wish me luck!!!
here is a quick youtube video i made comparing a faulty device and a working device
pay attention to the "dings" in the beginning of each part of the video, you may have to watch it a couple times to hear the difference - to me its noticeable right away. The first 3-4 seconds of the video sounds fuzzy/crackly... The same "dings" around 7 seconds are not fuzzy or crackly at all.... there you have it folks, Hardware defect!
Same issue here
Tried factory reset etc, still same volume lowering amd crackling
Here's the story: My Nexus 6 top speaker is making static/buzzing/white noise. I've gone through THREE different Nexus 6 devices already and I am extremely annoyed about this. I am pretty sure the first device didn't have this issue or else I would have noticed it, but it did have an extreme battery drain issue. The second one definitely had this same problem, which was why I got this third one.
After some rigorous testing, I noticed that the static occurs when you are locking the phone with the volume on, it gets louder when your phone is below ~20-25% battery and basically whenever the top speaker turns on (INCLUDING when you are actually talking on the phone, which bugs me the most). BUT, once you plug in the charger, the static goes away completely and will never occur until you unplug.
The fact that the first phone didn't do this bothers the crap out of me because now, I'm paying for a an extremely expensive phone with a hardware defect (At least my previous iPhones never had any hardware problems...).
Is anyone else experiencing this? I have seen a few threads on XDA but nobody really replied; also, there are Reddit posts about this and something has a Google Doc Group opened, but nobody's really addressing the problem. If this is a software issue, I'd be more than happy to sit and wait for an update, but if it's a hardware issue, then I want a new phone..
I get static when my phone starts to ring or get a notification sometimes. It sounds like its lagging, loud, and heavy crackling. Im pretty sure this isn't hardware related and will be fixed with a software update
I've got it too so I don't think it's your phone.
Seems more like a lag/software issue. I too was thinking it would be addressed in a software update so I wasn't too concerned. Music sounds OK and so do my calls so um yeah.

I hear it when I'm on calls as well, which is the most annoying part. I think I'm going to swap it in one more time to be sure... It doesn't cost me any money, I'll post an update when I get the new one. In the meantime, is anyone else getting this?!
Yeah I don't get it on calls that I've noticed. Mostly system sounds when I get notifications and various apps become active like I'm getting some lag maybe? I've noticed though that this phone is so fast its nothing for me to have 20 or 30 things open in the background and not realize it so I'm not sure if that was part of it I'll have to pay attention for a few days I guess

Same issue on my side. I don't think a lot of people have the phone yet so maybe that's why you aren't getting a lot of replies. I am getting a ton of white noise especially while on a call. Its so loud that its really distracting and hurts my ears. I returned my first one because it was defective and wouldn't make or receive calls and nobody could figure it out. Now I have this one with tons of white noise and static. Very disappointed with nexus. I was expecting quite a jump from the nexus 5 and with having a defective phone from the get go with the 6... Im about to divorce the nexus brand altogether

I'm officially on my 4th Nexus 6 and to my dismay, it is still there. Going to pray that it's a software bug and hope it goes away since my 14 day grace is up. Any other insights would be great..!
I get it a little on some incomming notifications , i'm pretty sure its not the actual hardware though , playing music or youtube videos doesn't have any distortion or noise.

Thanks for the update! I don't believe our issue is the same as the one you documented on your video. My speakers work fine and don't crackle that way during normal use and it is only the top one when you put your ear close to it or if you are in a quiet room (which I am, majority of the time when I'm at home).

I would say that's under warranty for a replacement. Have you tried it in safe mode and experienced the same issue?

Yep, I tested it out of the box stock everything right when I got to a quiet location (my car). Put it into safe mode, still heard it.
I seem to be getting the similar issue as @wilson289 which is static in calls but nothing on Audio, youtube, music, etc. Only some of the stock Notification tones as well as lock screen.
Sometimes when I lock the phone the static sound lingers for 3-5 seconds.
Called in for a replacement, lets hope its ok. My device is perfect otherwise so I dont want to end up with a more crappier phone.

Any update? I think I have the same issue. Noise specially in low battery
Same issue for me. At first, I only noticed it on incoming texts/notifications. It would sound like the notification was "jammed" and was slow to come out (if that makes any sense) and it would be crackly . Then I would test it on a ringtone or video and the speakers would sound ok. The other night, I noticed a periodic white static noise coming from the phone, lasting for about 1 second and occurring every 2-3 seconds. Phone was at <10% battery at the time.

I'm on my 4th Nexus 6 and still have the same issue. My 14 day grace is over now and so if I wanted a replacement, I will probably have to do it through my device's standard 1 year warranty. I figure to wait a few months before I go in for a new one so that they will have it in stock for sure.
I had static on my first Nexus 6 but not my replacement.
Sent from my Nexus 6
Called into AT&T for a warranty replacement, they are sending me a new phone, will keep you all posted. If this 5th phone is still ****ed up, then I will just admit defeat and accept that it's a software issue... Might even get to the point of selling the phone and going the direction of the OnePlus or back to Apple (don't shoot). Will keep you all updated.
same issue for me.
sound cracks sometime (especially ringtones and notifications)
and when the battery is low (less than 15%) I have curious noise coming from the device
