Hi

When you press the power button and put the phone into stand-by the phone is still very much alive and powered. The CPU may be off, but memory and the cell/Wi-Fi radios are still on and they require power. What you are hearing is a DC to DC converter which works by rapidly switching current on and off, and this can cause a slight buzz. When the phone is 'on' the DC to DC converter is required to supply more power and the frequency of the switching increases so the buzz stops or is inaudible to us, when in standby less power is needed and the switching slows down and becomes audible.

This is a common complaint with laptops that need power supplies to cope with a wide range of currents, LCD TVs are another device that buzzes for the same reasons and get these sorts of complaints.

Because the buzzing is a harmless side effect of the power regulation, not all phones may have it, or some peoples hearing can't pick up on the frequency, it may come and go with different temperatures. A phone with no buzz now may develop one in a few weeks or months, a phone buzzing now may stop by itself in a few months. Like something vibrating behind your cars dashboard, it may come and go.

If you can only hear it with the phone right to your ear, just don't worry about it. Any thing that adjusts voltages from one value to another can make a noise, from a 50Hz/60Hz mains hum we are all familiar with from mains transformers, to squeals from switch mode power supplies that work at much higher frequencies.

Regards

Phil

You people are crazy. You are complaining about the most insignificant things.
[Nexus 4 General] ewuzh:
Just received my 8GB from Google yesterday. Great phone except I immediately noticed two annoyances.

- Buzzing from earphone speaker during calls and also when the phone is just idling

- Rattling when shaking or even just setting the phone down on a surface

There are those having similar problems and also those with perfect handsets which likely alludes to poor build quality or QC. My Galaxy S3 GT-I9300 does not have any such issues and in fact seems perfect in comparison to N4. Anyone with an N4 that has the same issues would be crazy not to notice them.
[Nexus 4 General] Richieboy67:
Return it if you think it is malfunctioning. From what I have read from most users the builds quality is amazing. Perhaps this is just your phone with issues.

As for this buzz could it be the headphones you are using?

[Nexus 4 General] ewuzh:
I've no intent to return it. At most I would be looking to exchange it for another. Not using headphones, the buzz comes from the phone earpiece itself.
[Nexus 4 General] dwang:
I'm having issues with touch screen sensitivity when plugged into an USB port (think pad x220). Swipes become very unresponsive.

No issues with sensitivity otherwise, if unplugged or plugged into an outlet.
[Nexus 4 General] NardVa:
Most of the issues they are complaining about probably want be noticeable to the average phone user. XDA users are some of the hardest critics when it comes to a smartphone.
[Nexus 4 General] mcgils:
I'm thinking that your screen looks better, but maybe that's personal preference?
[Nexus 4 General] Jaso333:
I had the same issue this morning! When I tried to pull down the notification panel with 2 fingers to get the quick settings, it was losing control and opening apps and dragging icons around on my home screen. Only when plugged into USB charger.
[Nexus 4 General] richteralan:
Why all of this suddenly sounds like Xperia S all over again.

For the touch screen issue when plugged into a USB port, my Xperia S had the same problem. Went away with a firmware update.
[Nexus 4 General] rican408:
Not enough to get me bothered... But charge your phone and go to Google earth for a few minutes.... Now you can fry am egg on the back of your device. ;)
[Nexus 4 General] Danny80y:
I don't think there are a lot of people with the "issues" stated in this thread... except from the guy that pointed out not many have received them yet.
[Nexus 4 General] Swazi Samurai:
I noticed a faint buzz from the earpiece during calls. The back (top half) would get very warm after short use like downloading a few apps consecutively. I was extremely impressed with the screen and never experienced any washed out colors or yellow tint. I just wish I still had it. The phone crashed during a benchmark and is completely dead now. I'm waiting on a replacement from T-Mobile.
[Nexus 4 General] Seemonsters:
Agreed I prefer his screen from the provided photos. It's sharper and more mellowed out.
[Nexus 4 General] danielsf:
Please bare in mind I am using a galaxy s3's camera which way over saturates photo's at times, I mean look at the red on the chrome icon on the O2's nexus 4 and on the photo it looks like it could give the s3 a run for it's money in saturation, but in life it was bright but very natural and unsaturated. Samsung seems to believe the more saturation the better, even in their camera software, which is where I most dislike saturation, I wan't my images to look natural :) As I'm trying to capture life, not a cartoon :) And in life the nexus 4 looks more under-saturated than the photo's shown. Photo's are terrible for trying to show of the actual image color, it was only to show google play that there was a difference that was substantial enough to warrant a replacement. In person my device looks so much less sharp than the other nexus 4, that really was my biggest problem. I asked the store laddy if she noticed a difference and the funny thing was she said mine was a lot less clear and sharp looking and the grey's which are just plain yellow. :) When I was focusing the camera I always did it on my nexus 4, so looking at sharpness from the image really doesn't do it justice. :) But the main problem was brightness, my nexus 4 doesn't appear much brighter than my s3, but the shops was considerably more bright. I mean so bright that if I focused my s3 on it, it would distort my nexus 4 screen too much which is why I always set the focal point on my nexus 4, which makes the other appear in the photo to be less sharp when it wasn't :)
[Nexus 4 General] shadymouse:
Agree, I thought the O2's Nexus looked too bright and unnatural compared to his Nexus. However, the last picture is a night and day difference between the Nexus 7 and Nexus 4. Let's hope that is just a bad screen!
[Nexus 4 General] flucks:
The buzzing while on a call is really bad as well as the washed out colors and rattling.
[Nexus 4 General] B97:
I compared mine to your pictures taking into account you took them on a S3 camera. Mines in the middle really and personally I prefer the colours on your screen to the 02 one. I then compared the colours of the chrome icons to my laptop which I used as a 'normal' reference considering it has a normal LED display. My Nexus 4 display has crisper colours which I think look nicer to be honest. But, it's all down to opinion I guess.
[Nexus 4 General] Harsh:
Those with faint sound in speaker try keeping your ear next to camera on back of the phone. That sound is louder to me there. I really think it's a problem.

[Nexus 4 General] tehrules:
Got the Nexus 4 to replace my Atrix and so far I have come across the following disappointing issues:

- Low sound output from headphone jack (Volume in the car has to be set so high now!)

- When the car charger is plugged in and using headphone output - MASSIVE interference from the charger making it impossible to listen. Never had this issue with the Atrix and that was plugged in the car all the time.

- Buzzing when on call, seems to go half way through the call.
[Nexus 4 General] djmomar:
I haven't noticed the rattling or the buzzing from the ear piece.

I do have the clicking noise from the USB port, and I'm wondering if its a defect since it happens with all of my chargers.

As of right now I can't get Google wallet to get past the initial loading screen, and NFC is eating my battery.

I never had an issue with my gnex leaving NFC on all the time, but I'm guessing a software update will fix it.
[Nexus 4 General] Richieboy67:
No offense but you had 3 faulty nexus 7s and now this is faulty as well? Do you think you just may be possibly a little to much of a perfectionist or that you may be seeing problems that are not really there? I am not saying that all your exchanges were that way but out of 4 devices, you got 4 bad ones? Either some really bad luck there or maybe you will just never get one that will be perfect in your eyes. lol

I saw the images and though they look a little different, I did not think any of them looked bad out washed out really. I am using a nex 7 and I could be wrong. They don't look bad to me but I am sure they look different in person.

Sometimes my N4 stops playing any sounds. That's annoying ... I missed some important calls because of that. After a reboot everything seems to back normal. Even happend the first time before I had installed an app.
[Nexus 4 General] barmanham:
Lol at some people perfering your yellow piss screen. This problem existed on nexus s then supercurio made an amoled tuner and you can manually fix it
[Nexus 4 General] Hexxer:
Testing around. Bootet in the morning and i see that Wlan ist going offline if not needed. Make a little trip to town und use navigation to go back. Since this Wlan isnt going into standby. My point of view ist that there is a bug und that Wlan eat my power.
[Nexus 4 General] danielsf:
Hi, with the three nexus 7 my first one had a huge screen lift that topped what a lot of people had according to their photo's, my second had an out the box blown speaker and that three was a typo from my writing that when I couldn't keep my eye's open :P I only had 2 bad nexus 7, sorry and thanks I'll correct that now. But with the two nexus 7's they were pretty major things and many people on the forum often said they go over 2 replacements. Yeah I am a perfectionist, the o2's nexus 4 looked like the htc one x and iphone 5 and was one of the sharpest display I have seen, mine looked dull with some kind of white washed film over it. When the screen is the hardware part that is most likely to affect me, I would like it to look as good as other of the same device do. :) After looking at Engadget, my display looks like theirs. The O2's n4 looks like every other review phone I have seen on you tube etc in person.
[Nexus 4 General] nalinbhatt:
I think that colors on ur N4 looks much better. If you compare the first pic with ur N4, the colors looks natural on ur phone versus the 'bluish' colors on the O2. Not sure y u r unsatisfied with the screen quality.
[Nexus 4 General] tehrules:
O2's Nexus 4 is the LG Nexus 4 that you get from Google Play. There is no branding on it what so ever, even the box. O2 also claim that it is sim locked, but I doubt it.

I am an owner of an O2 LG Nexus 4.
[Nexus 4 General] WIIWONWON:
You are right. But the buzzing sound from the back disappears if the screen is off while it still remains on the earpiece.
[Nexus 4 General] pantweb:
is it normal the it tries to refocus on each small change of target / hand movement?
[Nexus 4 General] DonJuan89:
I can also confirm the hissing sound in the earpiece. It is loudest when you put your ear to the back camera. But it's not that loud that I would notice it if someone else didn't point it out. Only got my N4 today, so I have yet to see if it'll bother me at night. I don't think so though, the hiss is really low.

I just hope that it's not draining the battery or something.
[Nexus 4 General] tehrules:
Yes, it is a software feature I assume. My digital camera with 18x zoom will do it too.
[Nexus 4 General] thegripmaster:
I get the same hissing noise from the earpiece, whether the screen is on or off. I got a 8GB model.

With the screen turned on, hissing on both sides of the earpiece. When the screen is turned off, the hissing is on the earpiece side only.
[Nexus 4 General] antonusklesk:
I've experienced a looping force close of "Bluetooth Share". Someone with an original Galaxy S tried bluetoothing me an image - As soon as they tried to send the message appears that "Bluetooth Share has stopped working", this is a continual loop unable to turn bluetooth off and unable to do anything with the phone as every few seconds this appeared. Rebooting did not fix it, Airplane mode stopped it happening but as soon as Airplane mode was disabled it started again.

The only way to fix it was to clear cache and data for the Bluetooth Share app. Quite an annoying bug and I've not tried to replicate it.
[Nexus 4 General] huntedsoul12:
I too can hear electrical interference like hissing noise when on the call, its annoying. i dont know if its a hardware or a software/kernel related problem :(?
[Nexus 4 General] Stryder5:
An option should be added to say there is nothing wrong with the phone.
[Nexus 4 General] Richieboy67:
Can someone make an audio recording of this? Otherwise I have to think you guys are blowing this out of proportion..

sent via xda premium with nexus 7
[Nexus 4 General] MattSkeet:
I'd believe hissing sound so due to grounding of the speaker. And it's a hardware fault
[Nexus 4 General] 666fff:
That would be hard. It's such a low crackle/hiss sound. You really need to press the phone against your head and be in a quiet room to hear it. Ambient sound is much louder. My only worry is if it is using battery constantly....

Edit:

Just found out it stops after being locked. Gdgd.
[Nexus 4 General] :
Locked? As in screen off?
[Nexus 4 General] Joshr:
Still haven't gotten my phone yet but I can not hear any type of hissing/noise from my OG evo or my girlfriend's Vibrant (screens on or off).

I really hope the N4's hissing isn't that noticeable... that would bug me.
[Nexus 4 General] OneStepAhead:
My Note got several days, Note 2 probably does as well. I get about two days on my GS3 if I stay on wifi, and I usually do.

I posted some pictures in another thread about the problem with my Nexus 4. The entire screen has a yellowish grey tint, has a bad panel. Google is expediting an advanced replacement. Very easy process too, and I wasn't even the original purchaser.
[Nexus 4 General] noobdeagle:
that whine noise sounds alot like what ive heard before from inverters in LCD TV's and other electronics. considering it makes the noise when the display panel is on id be willing to bet its cause by the power components inside the phone this is not uncommon in high power electronics however in a phone this is a new one to me.
[Nexus 4 General] 666fff:
Correct. Not sure how long after screen lock the hissing stops, but it definitely does. Certainly within 5 minutes.
[Nexus 4 General] soulja786:
The vibration is terrible! Currently using the phone without a case, and on a glass table you can barely hear it vibrating! Hope this will get better when/if I put a case on it. :(
[Nexus 4 General] Richieboy67:
Uh dude, vibration is supposed to be felt by your body. It is not meant to be heard.. if you are worried about hearing it on your table then use the ringer..

You guys are just wanting things to be wrong with this device..

[Nexus 4 General] Higgsy:
Listened for the hiss from the earpiece when not in use - thought it was there, then I realised it as my stubble rubbing up against the phone!. However there is interference/static/hiss, I dunno exactly how to explain it, that comes and the goes while on a call - I had exactly the same on my LG Optimus 2x on certain radios. Doesn't bother me really though.

Haven't got any other "issues" to list - my screen is excellent imo, no yellow, no blotches, vibrant - Its far more consistant than my Note 1's screen.
[Nexus 4 General] Richieboy67:
Stubble!! Haha

Yeah, I was hearing something strange and then realized it was me breathing.. Haha

Anyone else tried plugging the phone into their car with a car charger, and then tried to play music through the car speakers?

I mentioned this earlier on in the thread, I get awful background noise, its so bad I can't listen to the music. I am using the same charger I used when I used my Atrix and this did not have the interference issue. Will try and do a sound recording and upload it.
[Nexus 4 General] petergoogle:
Can we take a moment and reflect ? Why are you guys so crazy ? Many maybe most people here don't even have the phone yet, but are discussing "issues"?

Do not read or pay attention to this because it will make you hear hissing in your head because someone told you. Everyone should judge the device unbiased to reach any conclusion.

On a more happy note, it's now day 4 and my impression so far is that this is the fastest, smoothest most stable mobile device I've ever owned.

The only issue I have is that battery life isn't out of the ordinary. I get 2-4 hr of screen on time in a 24hr period with moderate to heavy usage. Do I give a ****? No, this phone is good enough that I'd wear a solar panel on my head if I have to.
[Nexus 4 General] Higgsy:
I agree with this 100%, not seen any lag once
[Nexus 4 General] Spitfire:
Is it the cable that came with the phone? My G2X screen would get weird on me when it was on a particular charger, worked fine on others. Maybe there's some sort of weird incompatibility.
[Nexus 4 General] Lockeskidney:
i feel like there is an XDA syndrome. I follow all the new phones that are released on here and there is always a laundry list of issues
[Nexus 4 General] soulja786:
Uh no dude, even with the phone being next to me or in my pocket, the vibration is crappy! I've heard/felt much much better on other phones and it was very good on my Gnex. ...

It is a very light vibration.

And no, its an excellent phone! Best I've had. I don't 'want' anything to be wrong with it.
[Nexus 4 General] Hexxer:
I found my "battery eater" (dont now if anyone has read that).

If you activate Google-Now you "Location History" is also activated. That takes Wlan (Wifi) alsway on (also if your Wifi should be idle).

Here you can see it. Wlan is that blue long line - always on.

I play around last days and find "Location History". If you turn it off (you can do this with google now) Wlan will stop if not needed.

You can see it here. The yellow line is a test and marks the activation of "google now".

GoogleNow and/or Location History eat my battery.
[Nexus 4 General] dwang:
Its with the usb cable that came with the nexus 4.

Call quality on BT

Does anyone noticed poor voice quality while using bluetooth headset?

I have Samsung galaxy and 2 BT headsets, both work great with galaxy (using the same sim card). But N4 sounds horrible. Sometimes I can not understand person on the other side. I have a feeling that music over BT does not sound as great as on my old galaxy.
[Nexus 4 General] tehrules:
Or perhaps, there are issues, and its better people find them now so that they can be fixed in future batches. Good for you, your device appears to be perfect, but a lot of peoples are not.

There are a lot of problems with hiss in the ear piece when on calls, even I noticed this.

I also find there is an awful noise when the car charger is plugged in and I am using the AUX in on my radio to listen to tunes, and this was not present on my previous phone.

So please take your comments elsewhere.

However I also agree it is the fastest, smoothest most stable mobile device I've ever owned. And my battery life is progressively getting better as I use it less, and tweak how I use it, along with the whole fact the battery is conditioning its self.
[Nexus 4 General] magn2o:
+1 for the audio hiss in the earpiece. Everything else is perfect. :)
[Nexus 4 General] AdamHart612:
Just got mine a few hours ago, only complaints are that out of the two I bought (fiance and I) one has a mushy power button while the other is perfect. Naturally, she gets the perfect one. Otherwise all good.

[Nexus 4 General] levi-17:
Dose anyone else's nexus 4 have random fast reboots I've had the nexus 4 for two days now and its randomly rebooted twice.:o
[Nexus 4 General] thegripmaster:
Maybe your device is flawless. However the hissing issue is genuine. I noticed the hissing issue the first time I put the phone to my ears, without ever reading a single thread in xda. Searching for the issue on google got me to xda.
[Nexus 4 General] macca118:
I have the noises coming from the earpiece as well, but voices also get a but distorted at higher volumes, or when someone talks more loudly on low volumes. I saw someone else describe it as it sounding like the person on the other end was talking through a kazoo.

I can still hear the noises when the screen is off as well
[Nexus 4 General] petergoogle:
I don't think I explained myself properly. It is a great idea to have such a thread and discuss issues, share solutions etc.

My complaint was about non-owners pulling perhaps premature issues and running into the wild and spreading rumors or incomplete information about the Nexus 4. We aren't testing in a controlled environment and there isn't enough data to make conclusions yet in my opinion.

Another day with the phone and the only complaint is still the battery life. After the last charge i was able to do 2hr total screen on at 50%, 1hr voice, 15min Maps, for a total of 16hr on.
[Nexus 4 General] amdhunter:
Black dots under screen. At first I thought it was a dead pixel, but the blurriness around it makes me think some glue didn't cure properly. Google was prompt and I have a replacement being sent to me already.

At least their post-sales support is good.
[Nexus 4 General] Richieboy67:
16 hours isn't bad at all. Do you expect 8 hours of screen time along with everything else? I don't think it sounds to bad at all.

Hey guys, today I have found out that my wall charger makes noise when its connected to power and the noise still goes about 30 seconds after plugging out.

The noise is low pitch and it sounds like something vibrating.

Is this dangerous?
