Hi - just wondering if anyone else noticed some background noise / distortion when using headphones on the tab 7.7.
Happens when playing any sound and continues for 2-3 seconds after it stops. Tested with the stock buds and some replacement buds I picked up a few days ago. With my over the ear headphones I can't hear it though. Easiest way to test is just by playing a movie and pausing it.... there is a hissing noise for a few seconds afterwards.
Maybe related: even with headphones plugged in, notification sounds come out of the speakers - this is my first Android device so I'm not sure if that's normal or not.
Just wondering if anyone else is experiencing this or if it might be hardware related. Thanks!

Yeah I get that too. Doesn't really bother me though. I mean, it's not like I can still hear it while playing music or anything...
Mine's pretty noticable, even when playing music/videos. Weird that it's totally quiet with my over-the-ear headphones

Personally, I only really notice it if there's a trailing silence from music or videos, but while there's actually sound, I can't detect it.
FWhile listening to music through earphones the music sounds fine. But today I connected it to aux on my friends car stereo and you could your hear a loud hiss. An iphone 5 and htc one were fine so its not the car stereo.
The other issue is that today when I unlocked my phone I sometimes had a weird screen distortion before the homescreen was visible.
Wondering if anybody else encountered the same issues
2 different volume types
What probably happened was the volume on your S4 was set low, which resulted in you turning your car speakers up. When this happens, you get a lot more of a static sound. make sure the volume on your phone is turned up enough next time
I don't have an S4 or know about your other problem; sounds pretty weird though. Probably just a bug.

Its a known issue when using low impedance headphones or devices. Check here:
http://forum.xda-developers.com/showthread.php?t=2258831
Ilabs i just checked out the other thread and i think my problem with the sound is off different nature. The hiss sounds like a high pitch tone and it only starts to appear when I click on play and even remains when I click on stop. Only unplugging the cable helps.

Probably a one time incident, haven`t had it myself so far. If it should happen more often do a data factory reset.
Hi all,
So I recently bought a new LG G3 - after having screen problems with the Oppo Find 7 - had the Oppo fully refunded, so was on the hunt for a new phone.
Bought the LG G3 instead - great phone (apart from the stupid button placement)...but there's a fundamental flaw with it - just sharing this here, to hear if anyone else has been testing it the way I have done in the video:
(Essentially the audio has a buzzing noise to it, when using the phone - this happens when you amplify the source)
I don't find it acceptable for a 2014 flagship phone to be like this.
I'm on the fence now to root it and/or flash another ROM OR just return it for a full refund - anyone else have any experience with different ROMs (ie 5.0 ROMs)?
EDIT:
I'm returning the phone: http://forum.xda-developers.com/showpost.php?p=57514537&postcount=12
Some test results: http://forum.xda-developers.com/showpost.php?p=57514889&postcount=13

That "beep beep" sound when connecting your audio jack appears to be unique to your device as I haven't seen any other G3 do that before.
Also, I stated in another thread about this issue, It only happens while the cpu is under load AND there is no audio.
Once the cpu load drops to idle the issue is gone.
Once there is audio playing the issue is gone too.
It's annoying while no audio is playing, But it's not gonna degrade your audio experience in any way what so ever when there is sound coming out of your phone.

Thanks for the input.
Well that's odd, I've gotten others saying the beep beep is normal, but the buzzing isn't lol.
Out of interest, do you have the same issue?
And it's also a matter of principle, rather than it also being a fundamental flaw in the design. No flagship phone should have such an issue.
Whilst music is playing it's not noticeable at the levels I play it at, but at low volumes, and whilst using the phone at the same time, I can hear the problem. I'll retest tomorrow to make sure.
Not because I'm looking it for it, but because something doesn't sound 'right'in my music.
If it's CPU causing it, then is it linked somewhat to the kernel (ramp up and down of the CPU) or is it due to the placement or 'communication' it has to do within the phone (hardware problem)?
Mine does the Beep beep thing when i plug in my phone to the sound system at my work. It's done it on every ROM i have tried. The hissing, i haven't heard for a while though.
To be honest though, it is completely unacceptable it's not been sorted though yet.

Hi !
I think the audio system is the only problem with this phone.
When hearphones are plugged and there's no sound, you can hear a weird sound (especially when you touch the screen).
I also have a problem when I listen to music, sometimes the music has a little lag, a little buzzing for less than a second, as if the phone didn't have the time to load the music. It sounds like an old used CD. It happens once every ten minutes approximately. I don't know if it comes from the fact that I listen to music from my SD card, which isn't a very good card (64Gb, 20$ on amazon). I should test it from internal storage to check that...
Anyway, I'm using ChupaChups ROM and the problem you're talking about is also present. But Chupa Chups is a stock-like ROM, so this isn't a surprise.
I'm planning on installing CyanogenMod to see the difference.
I'll report back here after that

Thank you!!
As for your issue - you tried disabling throttling from the secret menu?
I've done so - in order to avoid temp capping

What hidden menu ? Dev options ?
ChupaChups ROM includes a mod which allows the processor to have an higher temperature (I think the original limit is 65°, the mod is set to 75°). The mod is supposed to erase this kind of issue.

Well it's not much of a "mod" - just a setting that you enable/disable:

That's a link to what I did.
Essentially the reason I'm saying it for you - is the laggy nature of what you said - with my brief use of the G3, I noticed a little alg, until I disabled the temp and throttling

Okay, thanks for the info.
I just installed CyanogenMod 12 (The ROM looks very stable, but I only got it 20 minutes ago so...). The first thing I tested was the issue we're talking about here... It's also present on Cyanogen ! The problem does not come from the Stock ROM !

Legend - seems hardware related (as initially thought)
Unless CM use the same stock kernel - highly doubt that though!
OK guys - went into O2 store in the UK - they had a G3 on display.
(It was plugged in) - I could hear a LOT of static noise on my earphones with the amp connected.
Then I unplugged it from the mains - the static went away.
I then did the same tests as before and boom - same issue.
It's 100% not my device only and is present in the international G3 version.
My LG G3 is being returned tomorrow. It's unacceptable.

OK so I did tests -
Without the micro USB cord connected:
Audio playing - 0% volume (thus you can't hear anything) - static noise, no HDD-esk noise
Audio playing - 1st notch (you can hear music faintly) - static noise, no HDD-esk noise
Audio not playing - HDD-esk noise
WITH the micro USB cord connected - charging:
Audio not playing - Louder static noise, minimal HDD-esk noise
Audio playing - 0% volume (thus you can't hear anything) - louder static noise, no HDD-esk noise
Audio playing - 1st notch (you can hear music faintly) - louder static noise, no HDD-esk noise
Hope this helps everyone looking at this thread
So, I have a set of Sennheiser HD 598, a pair of Monster DNA headphones and Sennheiser CX275S in-ear earphones (for Android smartphones).
When I connect the HD 598 and the Monster DNA to the phone directly. I get no noise.
But when I connect the CX275S, I get the noise.
Could it be something to do with the impedance/resistance of the headphones and/or cable that is being used?
However I am not using an amp. Do you get the noise without the amp? Have you tried a variety of headsets??

Yes it can be the impedance - however this doesn't apply when I connect the amp -as it is picking up more than the source usually shows.
In other words - you CX earphones could be more sensitive (which I find surprising vs the HD 598) - but if you were to put an amp - I think all of them would show.
I've tested with a bunch of earphones and my headphones - all of which showed the same problem with the amp.
I know for sure now it's to do with the phone - now if some people would notice it or not with their given setup is another thing.
ie. their setup might not reveal the flaw (ie if I had never put the amp - I wouldn't have heard the problem).
Also - I've noticed a audible "click" / "lag" when music was changing. making me say: "Yup 100% this phone is being sent back"
Can't believe I'm back to my SGS3. over 3yrs old - no problems and trumps these flagship phones in terms of audio quality.
Just to add my part, the "beep beep" is normal when connecting headphones. I usually get a very quiet buzzing noise when I have the phone connected to a power source and have headphones in. I'll report back in a week, getting a warranty replacement so may be different
EDIT: Using a pair of Audio Technica CKS-77X in ear headphones

excellent thanks for letting me know - why are you getting a replacement? (this issue?)
I've already packaged mine ready for an amazon return.
I decided to pull out all the earphones and speakers that I have. And here are the results.
1. LG earphones that came with the phone - no noise
2. Old Samsung Galaxy S2 earphones - no noise
3. Old iRiver earphones - no noise
4. Sennheiser HD 239 headphones - no noise
5. Bose Soundlink speakers in aux mode using a cable - at the highest 2 levels of volume I can hear the noise.
So it may be an amplification issue.
I am not sure that LG would accept the product back here in Australia if I tried to return it as there is no noise with the supplied earphones and any problems with amps would probably be out of their warranty terms.

Cracks on the top IR Blaster (the one used for Quick Remote not for the camera) and your bottom microphone. Its a know defect with the G3 and they'll replace the phone for free

Not an amp issue - I think I showed that by comparing multiple devices.
It's the fact the source doesn't like to be amplified - and when done so, shows these problems quite easily.
The source (LG G3 jack) doesn't seem to be isolated/shielded well - that's the issue. Therefore normally nothing happens, crank the source up a little and it fails miserably.
It's 100% down to LG here - I won't say it again, but I've returned the LG G3 now. I'm done with their crap implementation. How on earth they would have missed it is beyond me.
Reviewers also need to wake up when they do audio tests. Useless.

dam ok
I noticed a constant hiss or static sound coming from my car speakers whenever there was silence during music playback from my phone when connect through the aux cable. I thought it was a hardware problem. Lucky for me it wasn't and I didn't have to exchange my phone or cough up any money. Easy fix was, I went into settings under sounds and vibrations and went to sound quality and effects and turned on the uhq upscaler and the static was gone. I worked and sound is much better! If the option is grayed out, insert the plug into the headphone jack. Hope it works for you!

Solution Partially works
I've owned 2 Samsung Galaxy s7s and the UHQ toggle works but I still get a hiss when I'm in an application and there is no sound playing. For example, when I have the GPS on, I hear the hiss until the navigation starts talking. This is the same situation with podcasts and spotify. It's annoying but is it just me? I'm ready to downgrade to the S6
If you are using it for AUX in, you can eliminate the hum from ground loops by adding a Y adapter, and a set of headphones to the mix of your aux in, it will cancel the ground loop in the headphones and will be crystal clear for you.

You'd probably be better off with a ground loop isolator. Less clunky.

So first day with the phone and I get in the car to listen to music and there's a hiss and just weird noises. I'm like awe crap, I've got a bad one. I pull out some headphones and there's no hiss.
I restart the phone and plug it back into the car and still a hiss, retest headphones, they are fine.
Is it bad or is everyone getting this. My note 5 is fine on both with the same test.
It's worse when charging, but my other phone [Note 5] is dead silent. When charging it's extremely bad, like an fm station losing signal.
Also posted this on redit and others are having the same result.
Try different auxiliary cable to further you hypothesis. But haven't noticed this. Will test in the am.

Toggled off and back on. The hiss or Humm is gone but the audio quality is the same as the speaker on the phone itself. I played with each equalizer setting to get it to sound normal to no avail. Guess I'm going to walk into a store tomorrow with audio cable in my hand and try display device and my device and see if there is a difference
THANK YOU!!!
Wife took my aux cable out of the motor home. I got it back to use my new S7 for the first time and HORRIBLE static. Proceed to blame wife for breaking the cable. Buy a new cable ... still hisses (uh oh, perhaps I should not have been so quick to blame the wife). Try on my home stereo, no hiss. Try in my trucks aux jack with same cable, no hiss. Try the same cable in RV, terrible hiss.
Interestingly, I found that if i had the volume on the phone down around 1/3 there was no hiss, but with the stereo all the way up the music was too quiet. But, 1 click on the phone volume up button, terrible hiss. One click back down, hiss goes away. When I first had the problem a few days ago, the hissing would actually vary with the beat of the music ... so weird.
Anyway, just went out to the RV, plugged in my phone, playing the music with terrible hiss. Flip the UHQ toggle and miraculously the hiss is gone!!!
So happy to find this easy solution. No idea what Samsung did to screw this up in the first place.
