Just wanted to know if anyone else noticed faint buzzing/scratching/hissing noises coming out of their headphone jack...
(and yes I have tested several headphones/earbuds and tested with my MDRv6's all with the same results. Its definitely the phone not the headphones)
When I insert my headphones there is a quick beeping sound that plays for a second or so then goes quiet.
When music is playing, especially soft music (a particular song was Instant Crush; Daft Punk) there is a hiss in the background, specifically when certain tones play.
It was terribly noticeable right at the beginning of a few songs, especially the one I listed above.
I also have button sound effects enabled. So When I press one of the soft UI buttons it makes a tick noise. However for about 5 seconds after the tick there is a long hiss then silence until I press another button.
The volume of the hissing/scratching noises is directly related to the actual volume of the device and the note playing.
Im on stock build 11c w/root, and I havent found a lot of info about this problem.
Just wondering if anyone has noticed this, or if this is a known issue?
If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use
Yeah the phone is brand new. I think I'm going to RMA....

Just got my G3 a week ago and didnt use headphones until I read your post, I tested many different songs with different players, stock player, google player, Iheart radio, pandora, etc, headphone sound is crystal clear on mine, I dont get any beeps either like you described, I did notice you need to make sure the jack is pushed in good and tight, I put it in and thought it was all the way in and sound was crappy, pushed a bit harder and it clicked in good and sound was great, do you have a case that may be preventing the jack from being pushed in all the way, I had a phone in the past that this happened to me with, had to cut away some rubber on the jack to make it fit snug, if none of those are the issue, I would look into a warranty claim. I am using the beats audio earbuds that came with my HTC M7 I had before this phone.

That could be the issue. I know on the 2012 Nexus 7, it's really bad. It's supposedly due to the microUSB port and the headphone jack sharing the same circuit, or some engineering thing like.
Wonder if it's the same or if they didn't shield the headphone jack very well and it's picking up interference from the microUSB port when charging?
I didn't want to leave this up in the air so I figured I would post an update.
I replaced my G3 through Verizon for a brand new unit. My first phone was of an earlier batch (came with the 10b update) the second one was of a later batch and had 11b pre-installed.
Both phones had the same issue. There is a hissing noise/distortion that comes from the headphone jack. Even when not playing music.
I noticed it on other phones too but not anywhere nearly as much. I understand that any audio source is going to have a little background interference but the G3 definitely has a more significant issue than others.
However it seems to be entirely dependant on what headphones you are using.
1st. I tested first with my Sony MDR-v6's which the problem is most noticeable on. Extreme hissing/background noise.
2nd. Then I used a pair of Audio Techina ATH-PRO500's and the problem was almost unnoticeable.
3rd. I also tried my Steel Series Siberia v2's and the problem was again almost completely gone.
4th. I also used my receiver at home. JVC 5.1 channel receiver with RCA speakers and a Kenwood sub, didn't notice the issue at all. However there where some occasional strange popping noises when no music was playing I didn't get on my GS3 or other MP3 player.
5th. Finally I tried the ear buds that came with my Galaxy S3 and the distortion was again totally noticeable with and without music playing.
This is most definitely an issue that totally depends on what headphones you are using not sure if it has to do with sensitivity or impedance (this is what most people think) however it is most definitely an issue. I saw a few threads saying that audio issues were a problem in Android 4.4.2 however LG/Verizon have yet to release a stock base on anything but.
I suppose I could flash AOSP 4.4.4 and see if the problem persists but I don't know if that would even be worth it.
2 phones and 4 headsets later this is starting to seem like either a software or a design issue.
However I have nothing but good to say about every other bit of this phone. Really besides the audio jack top notch all around.

I might have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Ive been having the same issue. I have a pair of Shure SE846 which are about 8ohms. I experience the poor audio, especially the noise in the left channel. I find that placing a call and then listening to music removes the left channel static but the sound is still kinda bad. Ill try your suggestion tonight and post back. Just wanted to let you know your not alone.
I despise my G3 because of this. Im looking to get a new phone unless I can fix this.
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
I haven't noticed any artifact issues on my phone when using headphones, however when I plug it into my vehicle and also plug in the charger that causes everything to go nuts. The USB interference causes a crazy amount of excess noise. I haven't ever actually tried listening to headphones while charging, so in the car is the only time I've ever noticed it. The same issue occurs when I plug in my Galaxy Tab Pro into the aux jack and charge it at the same time, so this is definitely not unique to the G3. I wish all phones had as good an amplifier as my HTC DNA does, I still use that thing for music because the sound is so good.

I'm having a different audio problem.
With headphones plugged in and listening to music using any player, the right side sound emits distortion/hissing noise at a certain frequencies. When I tested it with plugging a 3.5mm to 3.5mm to an external amp (JDS labs c5) the distortion/hissing noise is completely gone. So it's definitely not a faulty jack
The hissing is evident at the beginning of (first few seconds) Tina Area's Still Running and You set fire to my heart .
I'm testing it with sensitive iem (Westone Um3x).
So does this mean there is a problem with the internal amp of the g3 or more to do with the os bug that can be solved with a custom kernel or update.
Is this a common issue found on all g3s?

Hi! This worked perfectly for me but for me instead of tricking the phone into line level output mode, I detaching one side of my headphones before plugging it into the headphone jack then reattached it afterwards. I'm using pair of sensitive iems (Westone um3x rc)
Everything is quit with no distortion, just how it should be!
One thing, is there an option within android or an app that can permanently enable line level mode ever time headphones are plugged in without having to trick it.
If so, I won't have to sent my phone for repair!
Also are there any disadvantages for using line level with headphones?

Using line out shouldn't make any difference on audio quality. It only disables the remote (buttons and microphone).
Would also really like a way to force the line-out mode. Btw, does this affect all G3s? Cause right now I'm not sure if it's worth the hassle of replacing it.

I know but some how using line out causes the hissing from the right side to go away completely. Strange huh
Are you also having this problem?
I also don't want to return mine if it exists in all g3s and there's a easier work around.
Yea same thing. I have artifacts in the left channel except when I manage to force the phone to recognize the headphones as line-out. I did this with the adapter to test it and it's impractical if not impossible to use the same adapter all the time.
I'm gonna try doing this right this moment to see if it works: http://forum.xda-developers.com/lg-g3/help/hissing-noise-left-ear-playing-music-t2804065/page17

I don't use earphones with a volume remote or microphone so that's not a problem.
It could be more to do with the increase in output impedance but I might be wrong cos the volume level is identical to headphone out.
I'm also getting a lot of static background noise but it disappears after making and hanging up a call as mentioned in a thread.
But yeah a permanent fix by forcing it into line out or doing some changes in kernel would be much more convenient

Great news! I just tried the fix from that thread and it worked. Here's the post: http://forum.xda-developers.com/showpost.php?p=59601465&postcount=150
I'm using stock rom which had 3 mixer xml files and I edited 2 of them, mixer_paths.xml and mixer_paths_qcwcn.xml. Also, instead of changing the value to 0, I deleted the entire line as it was suggested later in the thread.
The artifacts/noise in the left channel are gone!

But mine is stock on stock Lollipop via official update and with the hiss coming from the right side.
Please excuses my ignorance but I know nothing about accessing and editing a ROM.
How do I get into the rom and into the file called system/etc"?
Hey, I'm not sure if anyone else is having this issue but when the dac isn't on, it's static during the music and when I'm in a call, there is static in calls on the left side. Does any one have a fix for this? I've had these headphones in my V20 and this is my first day with my V30+

Hi,
haha - and here I am and thought this phone was having hardware issues or something (does it ?) - perhaps it's just the headphones and they have an inherent flaw ?.
At least I'm getting the same weird behavior that at some points it plays fine but at others there's LOTs of (electric sounding) static on the left side.
It's actually never fully continuous for longer periods - it's more of a stuttery (multi-second) behavior for several seconds that this noise appears.
Also at first it was only via quad dac enabled - on AOSP Pie (internal LineageOS 16.0 build) it's existing no matter whether I play via Android Audio or Hi-Res Audio (USB Audio Player Pro).
And this exists on very low volume levels - there seems to be a connection that when the volume levels are raised (above 25/30% or so - I'm usually listening rather low but with this phone and hi-res - why not go higher ?)
it's way more salient and there also may be distortion involved:
An especially remarkable track in this regard is Thomas Bergersen's [from Two Steps From Hell] "Lost in Las Vegas" (around 08:30 or so towards the end, 10:14 long) towards the end - a rather electric part of the track and
when you raise the volume the output becomes rather distorted which might be connected to that "issue" and the left channel is also hissing/giving off static way more.
Perhaps audiophile folks and audio hardware experts have a better idea what this is hinting at ?
So:
not sure if it's an issue itself with the Xiaomi Hybrid Pro HD that they can't take that extra AMP (they are supposed to be low impedance and thus not require high output)
but somehow this behavior only occurs on the LG V30 - so perhaps there some kind of hardware issue ?
It seemed to have gotten better however from my impression with all those updates to the subsystems in the kernel - so it's perhaps just bad hardware design and the headphones are rather sensible
with their balanced armatures ?
Anyone else with balanced armature (BA) headphones observing a similar effect ?
I haven't had any trouble with my (dynamic driver) headphones. I wonder, have you messed around with forcing high impedance mode?

You mean high impedance adapters and such ?
Nope, only directly connecting the headphones.
And whereas before it only happened with the quad dac activated (which might provide more juice),
it now also seems to appear with the internal DAC used only (toggled via USB Audio Player Pro).
There might be a difference on how the internal and quad DAC interact or are active on recent Pie AOSP ROMs however ...
It still doesn't explain that weird behavior from the headphones themselves
Thx
I have tried it stock with no mods and it has static. Slide down the drop down and turn on the Dac and it goes away but only for music and system sounds. With calls it definitely makes noise all the time. I tried with a AOSP rom and it makes noise system wide because of the Dac. I did try my Phillips headphones and those work fine without the Dac on but I think it's a specific issue with these ear buds because I also have a 2nd pair and they also make the same noise.

Hi guys, I was a member here back in the windows mobile days, I figure this is a good place to ask some questions.
I have a LG v60 and while using Sony MDR-7506 headphones I clearly notice a distortion and noise creeping in at some point when I move the volume slider. It's only noticable while the HI-FI Quad DAC is on and mostly on the left ear. It's very easy to hear with MDr-7506 as they are very bright and reveil top end easy. I'm wondering if anyone else has noticed anything like this, or perhaps I'm having a hardware problem. I've tried UUAP with bit perfect and the noise/distortion is even more clear with that app. I can duplicate the issue with an audio signal generator playing a frequency. The distortion noise is not there on low volume and not aperant on high volume, it's somewhe in the middle but very obvious and audible to me with Sony MDR 7506. Also noticable with 32ohm beyerdynamics 770. Perhaps hardware problem or quad DAC plus low impedance headphones matching issue, I'm confused and hoping some of you might be able to help. Thank you in advance
I haven't noticed this with any of my headphones. I usually use a pair of Focal Clear (55 ohm). I'm no expert but I'd guess it's a hardware issue. If you have time you can try flashing older (or newer) firmwares to see if that has anything to do with it (I'm on an updated T-Mobile variant).

Thank you for replying, your Focal Clear is just above the 50ohm trigger for the Quad Dac. I bet they sound great with the V60 dac. I'm having issues with some of my 32ohm headphones not being amped properly and having to trick the DAC using an extension cable.
I wasn't aware of being able to flash older firmware on the v60, I'm on a Bell Canada model LM-V600TM and currently running V600TM10q firmware. I used the LG Bridge software to update it once since I got it. There's an update available so I'll try that next.
I suspect that's it's something related to the Quad DAC as it's only there when it's enabled, with certain headphones it's painfully obvious. Its right at or just above the volume I prefer to listen at. The MDR-7506 and dt770 250ohm both make it possible to really hear the noise floor on most recordings, exaggerated high frequencies could be the reason for that.
I would appreciate any links or info on downgrading the North American V60. I love this device, it's my first Android and I didn't know that the bootloader was locked or crippled when I got the V60. I spent many years in the jailbreaking iOS community. Apple removing the headphone jack was the main reason I gave up iPhones. It's good to hear that it's not all v60s that act this way
I found a thread on here that seems to be about the same issue, I posted here before I found it, hopefully it helps shed light on this. There's ppl from Germany that report the same noise problems so it's not just me.
Hi, I bought the nord 2 a few days ago, it's a wonderful phone but I have a problem.
The bluetooth audio quality is horrible. I don't know if it's only on my device , i have tried everything, the stock Dirac hd sound does not support bluetooth devices so the sound is flat. Also it seems like it's playing music on low bit rate. I have switched from aac to sbc there's a slight difference but still it sucks. Also changing some settings in developer settings did nothing.
I have Huawei Freebuds 4I and on every other device the sound is amazing but on the nord it's awful.
Currently I'm using wavelet eq but still the music is playing at a low bit rate. I don't wanna root my phone for viper4android so is there any other solution to this?

One plus Nord 2 is a budget phone yet not cheaper than other budget phones, yet they give a low-quality device like this. Try listening in a different Bluetooth headset.
No issue here, I have samsung galaxy buds+ TWS (aac mode) and a Marshall Mid (aptx mode) and bluetooth quality is perfect in both cases.
And for the lack of Dirac support in bluetooth mode I use the app "Poweramp Equalizer" to get some more bass in my headset
For music you can try jethdaudio player. It is extremely good.
I don't know what you are talking about I am using Realme Buds Wireless 2 on my Nord 2 and it sounds amazing and I mean it since I am picky about the audio quality with negligible delay like mine cost about 1/3rd of yours so it's probably a compability issue LDAC and AAC both work great on nord 2 ofc LDAC sounds better at the cost of more battery usage....

Maybe a faulty piece really should just visit a service centre with all those headsets and see if it can be fixed if possible test out some more headsets by asking from your friends. Also check the settings of the music app you are using it's unlikely but still possible that it's set on low
Can't get it replaced.. Cracked the screen 5 minutes after I took the phone out of the box
Most folks dont know this, but bluetooth is a modern NAME for 'A' software version of hardware based tech capable of transmitting 240v AC through the air.
Tunguska anyone? That was the test, and the origional copywright is owned by TESLA.
Bluetooth, was designed to do the same, it's designed for AC current, explaining why bluetooth digital audio is the WORST sound ever invented.
Blutooth sounds so crap due to the following:
1: The inventors of digital audio decided to remove EVERY frequency the human ear cant hear. (according to who?)
2: They are now removing the lower base frequencies that we COULD hear, if we had say speaker's like my set of BW speaker's used by the BBC in the 60's and 70's, which can produce EVERY frequency. To make these speakers today is £14.000 PER speaker.
3: By removing all lower frequencies, they removed what is known in music, as the BODY of sound. They started this with digital techno, aka goa trance. I stopped buying musical digital instruments just because of this. If you take a 90's version of say 'Rising High's Church of Extacy' ( The tune that officially killed rock and roll due to it's pure analogue sound quality, hardness, and the deepest bass ) then play it through bluetooth, all you hear is tsstsstsstss, because the tweaters you think are great sounding speakers literally cant play anything under the highhat, without ECHO to fake the BASS.
If it's audio QUALITY you want, DROP bluetooth. Simple.
Another note:
As a dj of over 40 years in the undergound dance music scene, the one thing I cant understand is why I now have no CHOICE but to buy headphones for djing with a bluetooth mic built in! This allows whoever is spying on what we SAY to record my tune or live mix before I leave the gig, and claim it as their own. Try buying decent ANALOGUE headfones for djing.
Final note.
Nfc: the modern day verion of blutooth. Interfere's with bluetooth audio in that the AC current also has it's own magnetic field, which can, like binaural beats, interfere with bluetooth. Most fones use bluetooth AND Nfc. nae luck.
I personnaly know the best hacker in Scotland. 12 letters after his name in computer sciences...! He wrote the bluetooth app the gov called tap n trace, and he sold it to them for £30.000, they added Nfc (Near field Communication) and got most people in the world to install it in their fone. NIce one Gi88's!
Bluetooth... did you bite?

I am using my Sony WH-1000XM3 and it supports LDAC. The audio quality is great with support for equaliser. The only way to get LDAC was change the mode from connection stability to sound quality mode in sony headphone app. By default, it supports SBC. Pls check your headphone's app and also check if your headphone supports relevant codec.hope this helps.
I had a similar issue with my Nord 2 and my Libratone Too BT speaker, sound was horrible, like an old cassette player. The speaker only supports the SBC codec, I think.
I was able to fix the sound quality by enabling developer options and switching to AVRCP 1.6 and MAP 1.4 there.
Update A.16 fixes Bluetooth audio.
the problem is just with the freebuds 4i, but I don't understand why..

At the beginning i noticed distortion sound coming with Alram sound and i thought it is the ringtone and changed it , used my mobile phone normally and sound is perfect playing music.
I searched the issue because i had doubts and unfortunately all the series has the same issue :
- When there is cold weather ( you can put the mobile at freezer for 5 minutes if you live in summer season now) the sound get distortion
- If you take your mobile to a flight , the same problem appears and sometimes the sound is not coming at all from the speakers
To solve the problem immediately , eject your sim tray out and surprise ! the mobile sound back to normal ! you can make the test over and over and the same result i tried may things , wiping cach ,restarting nothing solve the problem except ejecting the sim tray !
You can google it for S22 distortion and crackling and you will find many people on Samsung community had the same issue and even replaced it with new ones and got the same issue ! Also you will find a youtube video showing the problem .
I don`t know is it a software problem ! but i don't think so .
Please share with me your experience and your thoughts and if anyone can get an official statement from Samsung let us know .

Hello ,
I have tried Bluetooth earbuds , no distortion/crackling but at the same time when i play it on device speakers it makes distortion/crackling .
i did not try wires headphones ,but i guess no use since the Bluetooth are ok ,which means the problem in the debice itself .
you can try the freezer , put the phone in plastic bag and put in freezer for 5 minutes and try .
Also because i travel alot , the presssure from the airplane make the same problem and sim tray ejecting fix it !
I am so disappointed dude

Galaxy S22 Speaker Distortion and Crackling
If you are having speaker crackling coming from both speakers and you're within your return window, RETURN YOUR PHONE and buy a new one. Hopefully you get one from a new batch that was built right. Info only: I pre-ordered early and got my s22 around Feb 23rd. In colder weather, playing any...

[German]Some of the proud owners of a Samsung Galaxy S22 smartphone are facing a problem. The speakers of Samsung's flagship keep emitting unintelligible sounds, and people have to switch to a headset or earphones to understand audio output. The problem sometimes occurs after flights.

I dont think u understood what i meant. I said u need too try if distortion continues also over WIRED earbuds over USB-C, (bluetooth uses didferent transistors" inside the phone to send audio out over radio frequency) beacose its possible that this can be fixed via software, in case the distortion continues over earbuds. Its not only pressure that its the cause, it can also be temperature control over S22 amplifier or the other transitors that are responsible of sending audio output out of the phone (speakers, bluetooth or wired ) - u need too test it all at the time when distortion started to happening. And also try turn on or OFF the UHQ upscaller in sound settings, too see if distortion over speakers stops then. Its all about diagnostics. Myself when i switch UHQ upscaller , it stops over earbuds for example. (i got S22+). I saw all videos of that issues and i have read all Samsung forums and others, and the issue varies - and mostly its considering Ultra version, not other two devices of S22 series. Other two can have other codec problems or something. Maybe its even all connected too the firmware issue when it comes too audio outputs and stuff, since the S22 series at the same time has also audio/video syncin issues and whatnot.

Let's hope that is a software issue
I will find a usb c /aux connector and try the wired headphones and let you know the results for sure .
Just let me know how to turn off/on UHQ upscaler ?
One more thing i forgot to say , i tested during the flight also to leave the sim tray slightly opened for around 1 hour ( the same time left closed to test the problem ) and the problem did not happen !
so it suowed when tray is closed and didn't show when tray is not closed .
Under Settings go to menu sound quality and effects, and in that menu you will find that option. Im adding picture. HQU option is available only when u have connected WIRED USB -C earbuds. HQ audio works only over wired audio transmition.
Remember, when distortion starts, try listening over all 3 ways (speak, bluetooth earphones and more importantly WIRED earphones over USB-C). Then let us know, if distortion goes over earbuds as well. After that try that UHQ upscaller, but usilly helpes, issues still returns after a min or two in my case. Im thinking its software firmware issue....and If issues persists over wired USB-C , then try boot in safe mode, and test all 3 ways again - and if then it will be gone, then its almost certain, that its software issue. (U can also try at once when u take phone out of the freezer, and started crackling, boot into safe mode and check if the issue persists in safe mode.

UPDATE **** 12 Apr 2022
Hello S22 series owners ,
Cutting to the point , we all suffered speaker distortion problem due to getting the device in cold weather or on a flight ! and we all know about fixing it by ejecting the sim tray to equalize that pressure !
Well I have Galaxy watch 4 and it has an option after getting into water , to select from drop menu called ejecting water , and it make short tones !
And i thought it should be the same with the smartphone , there has to be a way to eject that pressure/mositure , i searched and found an application explained by someone on youtube channel ( Tech 786 ) called Sonic wave - sonic pitch tone sound generator ; you can find it as Apk just google it .
Anywya he was showing this app as a solution for ejecting water from a sumberged phone to clear the speakers from the water by playing 165HZ tone for a minute or so .
I installed the app , took my s22+ to the freezer for 5 minutes till showed the malfunction of the speaker then started the application and played the 165HZ tone and less than one minute the sound back to normal !(as if you have ejected the sim tray out ).
This is a hope that the problem could be solved by a software tweak , that when the phone senses a temperatures drop or too much pressure ,activates something like that or at least Samsung make an option like in Galaxy watch 4 !
Finally , i will have the device on a flight in 2 days ,i will test onboard during the flight , and check this app , will it help also without the sim tray trick or no and i will come back to you all.
Samsung please fix this !

Dont forget when u gonna test your theory, test also using wired usb earphones, if problem presist there too
I'd just like to say I don't have any distortion with my S22+. That's with USB wired headphones, being on a flight, playing music and notifications through the speaker... So, it's definitely not with everyone. Like someone else posted, if you're in your return window, return it!

this issue happends very rarely, usilly its all fine with earphones, but randomly rarely distortion starts...
I just noticed the same thing on my flight, when I landed the sound was distorted, took it two hours to stabilize.
I currently have a physical SIM but want to swap to ESIM in order to use dual sim overseas.
Anyone has a solution if using ESIM instead of SIM?
I tried the trick with the 165Hz sound wave, it didn't work after the latest sw update, I had to pull the sim card out.
