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.

[Verizon LG G3] drondron:
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!
[Verizon LG G3] mitchell4500:
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.
[Verizon LG G3] DigitalMD:
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
[Verizon LG G3] Homestar1217:
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.
[Verizon LG G3] Fungus999:
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?
[Verizon LG G3] Fungus999:
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?
[Verizon LG G3] sulkie:
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.
[Verizon LG G3] Fungus999:
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.
[Verizon LG G3] sulkie:
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://xdaforums.com/lg-g3/help/hissing-noise-left-ear-playing-music-t2804065/page17
[Verizon LG G3] Fungus999:
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
[Verizon LG G3] sulkie:
Great news! I just tried the fix from that thread and it worked. Here's the post: http://xdaforums.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!
[Verizon LG G3] Fungus999:
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"?
[Verizon LG G3] sulkie:
Unfortunately, you have to be rooted to access those system files. After that it's just a simple task of editing them in any text editor.

I'm sorry, I'm using a translator. I have a fake touch in the upper left corner of the screen (where the icon settings). fake clicks occur on all roms from Motorola, for CM 11, everything works fine. what to do?
[Moto G Q&A, Help & Troubleshooting] prakharkmr27:
Does it happen even when you've not connected your phone to a charger/laptop/computer?

If yes, go to the Motorola service centre, claim your warranty and demand a touch panel replacement.

The problem does not occur on the CM so to not mechanical failure

[Galaxy Note 4 Q&A, Help & Troubleshooting] jusho:
Still no LTE option:(
[Galaxy Note 4 Q&A, Help & Troubleshooting] zsnh_khy:
Are you sure you have bought Samsung Note4?:confused:
[Galaxy Note 4 Q&A, Help & Troubleshooting] newre:
Does your mobile operator has LTE? Usually you don't see LTE option when your network doesn't support LTE.
[Galaxy Note 4 Q&A, Help & Troubleshooting] vndnguyen:
Try this way (ROOT is required):

- Install ES File Explorer, open the menu and enable Root Explorer option.

- Locate the file /data/property/persist.radio.lteon

- Open that file, and change its content from false to true

- Reboot the phone.
[Galaxy Note 4 Q&A, Help & Troubleshooting] bankir:
Hey Jusho,

I'm having the exact same issue with your issue, no LTE option with TELKOMSEL. Have you fixed your issue? If so, how?

Did you purchase 910G in Singapore?

I went to Singapore recently and was able to go to Samsung Service Center... we tried a couple of things :

- Use M1 USIM card in MY Note 4==> LTE option appears

- Put my TELKOMSEL USIM in THEIR Note 4 ==> LTE option disappear from THEIR phone

- Put OPTUS (Australia) USIM in MY NOTE 4 ==> LTE option appears

Today, I went to Grapari and asked them to replace the USIM and tried with the local Samsung Store :

- Put TELKOMSEL USIM in their Samsung EDGE ==> LTE appears

Any idea?
[Galaxy Note 4 Q&A, Help & Troubleshooting] xdm9mm:
Hey guys, I had that same problem on my galaxy S4 before. I used a Straightalk sim card running on Tmobile. I called straighttalk and they replaced the sim card and everything worked.

Call your providers and ask them to change your sim for LTE compatibility. That is if your providers support it, and your phone supports the LTE bands.

Good luck
[Galaxy Note 4 Q&A, Help & Troubleshooting] bankir:
I did mention that I have replaced with the new USIM (4G card) and LTE option won't appear. And yes, my provider supports LTE Band B8/900 Mhz
[Galaxy Note 4 Q&A, Help & Troubleshooting] xdm9mm:
sorry missed that part as I was reading fast. Anyway, have you tried to set the APN settings manually?
[G2 Q&A, Help & Troubleshooting] Andr3y29:
Hi. So I have the opportunity to change my S3 with a black G2 that has a problem. the seller tried to root it, it got stuck to the LG logo, and then after he fixed it it says that it has the IMEI lost, but it has signal on all carriers (is it posible) ? i've searched online, and it seems like it is possible to fix it, but in many places I see that you need to restore the already backed-up EFS. And in some other places with that LG Octoplus box. Like here: [YOUTUBE]https://www.youtube.com/watch?feature=player_embedded&v=DrfUyei5HTw[/YOUTUBE] it seems really really is, but is it like that. If i find a written tutorial like this: http://www.droidviews.com/how-to-backup-and-restore-lost-imei-on-lg-g2/ it is a lot more complex.

So now want your verdict. Should I buy it, or not ? I ask you here because you owned the phone for a longer time, and you know what it should be done. thanks for your help !:good:
[G2 Q&A, Help & Troubleshooting] vPro97:
Well from my experience helping people in this forum, a G2 that has lost its IMEI and doesn't have a backup of its OWN EFS partition can pretty much only be used as a tablet. So no, that would be a bad idea. Also, how can it still get signal when its IMEI is erased? That's not possible :)
[G2 Q&A, Help & Troubleshooting] Andr3y29:
Ok. Thanks. I saw that tutorials with Octoplus that didn't seem to involve restoring something.
[G2 Q&A, Help & Troubleshooting] Izy:
actually imei is recoverable

got my phone sent back from LG with new mother bored did a twrp restore including EMF like a nab

managed to restore it by manually writing it to device using the imei wrote on label

[Nexus 6  General] Hand76:
Made a post about wishing Google had some form of backwards compatabilty a few weeks ago and it was kinda poo-pooed

Skip ahead to yesterday. Got my nexus 6 and within 1 hour i was unlocked and rooted with a custom recovery and unencrypted thanks to Wugs great tool kit.

Spent the next day getting used to 5.0 and setting up my phone... Tonight i breath a sigh of relief and I'm ready to actually enjoy my device.

Now whatever your thoughts are on gaming on a Mobil device you have to face it these devices are built for this very thing. These phones don't have all this horsepower and big beautiful screens for the internet and Facebook.

So i fire up Gta Vice city...it won't load a game, try the new one Gta Sa, and menus don't work can't save and load when in game. Tried the new Xcom Enemy Within game and graphic artifacts everywhere games completely unpayable. Over half of all the games i own don't work.

I have a brand new $700 device sitting on my counter while i have to use my nexus 5 under 4.4.4 to actually do the things i want to do! Something is wrong with this picture. Sure some of these problems will be fixed by devs over time... But who the hell knows when. Some companies have 30-40 games across multiple platforms...it could take forever (and usually does) for them to make updates...Now knowing that why does google not have a backup plan to make sure older software works on newer devices?
[Nexus 6  General] oneplus:
Why should google care about what developers make? Google rules, developers have to adapt and change the code based on Google decides to bring in each new version.

Sent from my Nexus 6
[Nexus 6  General] Hand76:
Because the developer has already made their money... The consumer is the one who is stuck with a product that doesn't work.

Let's see Google crack down then and pull every grand theft auto game from the market till rockstar updates them...But we all know that's not going to happen.
[Nexus 6  General] Jepod:
I have no issues playing GTA SA on my Nexus 6. Mine is rooted and unencrypted but otherwise stock 5.0.0. I actually am really enjoying this phone for gaming, something I've never really liked on phones before.

I'm not sure what has been done on your device so I can't give any instructions on how to fix your issue other than to not blame Google for issues with a few apps, especially when you're not using the device as completely stock/as intended by the manufacturer...
[Nexus 6  General] Hand76:
Menus become laggy after a little while of playing, cant load/save game. I checked reviews on google play many others on a nexus 6 are complaining of the same
[Nexus 6  General] Jepod:
That's weird... I've played probably 3 hours over the weekend of GTA SA and never once noticed a problem. I'll watch for issues as I continue playing it though.
[Nexus 6  General] Hand76:
Any other games you have tried? Anther one of my favs is Segas Jet Set Radio... That game would look awesome on this big screen... Doesn't even start :(
[Nexus 6  General] LeoRex:
Any time you hit a major OS update, you run into compatibility issues at first. I knew going in that I'd run into a few quirks.

But I ran into similar issues when I first got my G3... lots of apps weren't able to cope with the increase in resolution and needed to be updated. Waze had some serious map rendering issues, for example. But it got sorted.

It's the price you pay, sometimes, to be an early adopter.
[Nexus 6  General] Jepod:
I'm downloading a couple other games and will report back (though it may not be until tomorrow when I can report back). I'm downloading the following:

Welcome to the bleeding edge, OP. Someone told me iOS is better at this if you want to go there.
[Nexus 6  General] plasticarmyman:
welcome to a new OS, this is what happens across the board for all devices when a new OS is launched.

on windows, when you get a new OS update, not all software is prepared for it, same as everywhere else.

I personally have not had any issues with any games i have running on 5.0 and i game with a lot of big RPG's

Bards Tale is gorgeous on here BTW
[Nexus 6  General] mjs2011:
Lop. You should have seen the compatibility issues on iOS 8 and developers not being ready for bigger screens. They're still having problems!
[Nexus 6  General] hlxanthus:
Its actually kind of funny. Google actually tried to offer solutions to this problem this time around. They released the L preview builds and early api for app developers to have everything they needed to test and build their apps to support the newest OS version. Of course very few devs used those tools to get a jump on it . . .
[Nexus 6  General] MrDSL:
Yeah gaming is hit or miss...clash of clans runs wonderful but my castle clash runs barely good enough to play.

however i do have the latest software and what already appears to be awesome dev support so I hope this gets ironed out. The phone has the power the run the games even on the high res screen.
[Nexus 6  General] rufflez2010:
As an application developer, it would be nice to actually have the device to test on. Right now, I have to rely on the emulator for the Nexus 6. I don't make mobile games, but if their engine relied on Dalvik, you may be waiting a while for the game engine to be updated to ART (I don't think this is an issue as I've never had issues with gaming on my Nexus 7 tablet). More likely, you are dealing with an issue with resources not matching the Nexus 6 DPI... therefore, you're stuff looks out of whack, or can't click on menu items. You'll have to wait for more devs to get a hold of physical devices. The emulator is good for a lot of things... but there are somethings that are just broken for development...

Some examples I noticed

1) You have to turn off "Use host GPU" to take screenshots/record video off the emulator.... Disabling "Use host GPU" makes the emulator run like crap... takes like 5 minutes to boot on my machine.

2) Cannot rotate device anymore. With Gingerbread, you could rotate the device and test out your layout-land resources... nope, not anymore... at least not on anything >= Ice Cream Sandwich

3) HAXM... not an issue for me, but I get a lot of questions on my YouTube channel about why my emulator is smooth. I use intel processors on my computers. Many use AMD and development with the stock android emulator is a nightmare. I don't know if Genymotion fixes this for those as I haven't had an AMD processor since before Android existed as a mobile OS.

4) Freezes up randomly. Its just not as stable as a real device. Obviously this could vary on machine to machine. For some reason, my Nexus 4 emulator freezes way more frequently than my Nexus 5 emulator.

5) I store some files I need to test my app's database in Dropbox. I used to be able to download the file and run it in my program to create my database. I can't do this anymore. It works fine on my physical device, but I don't think my Note II will be getting Lollipop anytime soon. I need to test SD Card storage options and the emulator just doesn't work for this.

My Nexus 6 was promised to leave the warehouse by December 3rd... even paid overnight shipping.... still hasn't even been charged from my account. My point: Improvements will happen... we just need devices before we can fix a lot of issues with lollipop. Motorola/Google have really screwed this release up.
[Nexus 6  General] Hand76:
Thanks for the post Rufflez.

And for the person who brougt ms Windows up... That's a terrible comparison.

I have 10-15 year old games on cds that still work on win 8/7. Windows even has a comparability mode built in. Would be nice if android had the same.

This happened last year with kitkat (except wasn't as bad) and now again this year with art/5.0.

Google thinks devs are going to update all their software every year??? Isn't that expecting too much.
[Nexus 6  General] simms22:
modern combat 5 plays absolutely incredibly on the n6! graphic would rival any console game.
[Nexus 6  General] polke45:
This may be wrong, but I think Google likes to make software not backward compatible due to security features. In Windows, having the ability to run a software made for Windows 95 is great, but with a built-in emulator, old existing security loop hole will exist in newer version unless they patch up. What Google is doing forces all apps to change to meet the security standard so this allow Google to have more control of the apps development vs having a large QA team to release security patches similar to what Microsoft is doing on windows. Not to mention having backward compatibility (not just KitKat) will increases the size of android l os, which is not ideal on mobile device
[Nexus 6  General] akhan47:
If gaming was that important to you, why did you purchase the phone before reading the reviews? It will take a while for these games to be optimised for Lollipop/Nexus 6, this has always been the case.
[Nexus 6  General] Saschwatch:
The knights have arrived
[Nexus 6  General] Jepod:
I tried a handful of games and only one of them didn't work. All of those that worked did so very well too.

Worked: GTA3, GTA:SA, Modern Combat 4, Dungeon Hunter 4, Baulder's Gate, & Asphalt 8

Didn't work: GTA:VC

I tried nearly every combination of settings in Vice City and nothing worked. It would begin to load into gameplay but would exit the program at around 85% loaded (no # is shown, just guessing off the bar on the bottom of the screen). Overall I am extremely pleased, I remember when ICS came out and half my games didn't work. It took months and months for some games to finally be fixed. Sure, there will always be those developers who are either lazy or have moved on to other programs and haven't had time to come back to a an older program. I for one love my N6 and Lollipop.

P.S. Vice City doesn't work on my Nexus 9, Nexus 5 or Nexus 7, each running Lollipop (stock + root). I'm thinking its an ART problem.
