TIP #1:
If your G2 stock earbuds fit your ear canals really well, see if they fit on your other earphones!
I tried these G2 ear buds on my ie-80 in-ears and i can honestly say they give the best seal i have had in 7 months since getting these earphones!
The G2 buds have an abnormally large hole diameter which allows alot more high/mid range through than my previous sets. Stoked!

TIP #2:
Clean your in-ear headphones regularly, scotch tape works great!
Pull off the earbuds and carefully dab (do not rub) each the earphone housing speaker grills repeatedly with sticky part of the scotch tape to remove any wax/dirt buildup.
Repeat this once every 1 - 2 weeks to ensure longer life/good sound of your earphones.
If possible store your in-ears in a clean container/sealed carry pouch so they do not collect dust/lint/dirt from your pockets.

Thanks for the mod. Tested a FLAC song with stock music player on speakers. Max volume and no distortion.

Great to hear!

On a note of personal note, i had viper4android installed on my LG G2 but with these modifications,
i ended up uninstalling it as i was primarily using it for volume boost purposes as opposed to signal shaping/eq-ing.
I also found that viper4android would work randomly with some files but not others.
IMO Volume boosting should work consistently at all times, across the board.

From the purist/consistency train of thought this volume mod will give you consistent volume boosting and more power to your headphones (fuller sound) without altering/degrading the already superb audio signal, or adding digital noise.

That being said, viper4android is a great app for shaping the sound signature, which is what it is primarily designed for.
For me, "the closer to the original source, the better"

Much improved sound. Thanks.

Soliciting for "thanks" is kind of lame especially considering I saw this mod first in the link you provided in the OP

This is an external Speaker and Headphone Volume level modification.
It is what I feel "should have been" the stock "happy medium" audio levels for the LG G2.

The DAC audio quality coming from the LG G2 is excellent.
This modification brings the listening sweet spot down to 50% volume level instead of the 80-90% volume range at stock.
Stock levels did not push test headphones as well.

Benefits:
- Removes the need for 3rd party audio VOLUME BOOST apps
- Does not alter DAC raw audio signal quality
- Provides optimized signal drive for higher ohm headphones
- Improved audio fullness
- Improved low end at optimal listening levels

That is what I did, just wanted to make sure it was right. Someone might want to add that to the first post.

Permissions should not make a difference in this case, however you can set them to rw~r~~r~~ for the file as shook mentioned using root explorer.
Mine are currently set to rw~rw~r~~ and there is no difference in performance.

I have updated OP with step 6 as optional. Cheers!

Really.
Well not giving thanks where its due, is even more lame, not to mention it is Thanksgiving today after all..

1. For what its worth i stumbled on this file in my G2 looking through sys etc files as a result of modding my note 2 last year in similar fashion, when i was looking for volume boosting without 3rd party apps at the time.

2. I have spent time testing to ensure i get the levels right on a fair range of equipment, and i feel others should be entitled the chance to benefit from this as well.

3. That thread that i ended up finding (and linking out of courtesy regardless) is pretty convoluted and a bit of a mess, labelled ATT (i am on Bell and this is a universal fix, not just ATT), and realistically only addresses speaker volume.

4. I have provided a working tested version of the file that G2 owners can use if they choose; not everyone is comfortable/has time/patience to edit/test settings in order to enjoy the untapped potential their phones have to offer.

5. I was in actuality not soliciting (seeing as we are NOT selling anything here), but making a factual observation through my thanks post, and the same applies to all positive dev/mod work.

You're welcome.

 

[nic85]

thanks, audio seems improved and much higher.

maybe a bit too high.. I can't set volume up to middle.

The version i posted on this thread works fine with no issues.
I have tested the scenarios detailed in your post using 2 different cell phone lines, calling my g2 from another cell, and vice versa.
Both with speaker mode enabled/disabled, and with/without headphones.
Mic works fine in both cases for me, no issues here on my Bell version G2.

I do not currently have a pair of headphones with microphone built in to test that format though, if anyone else can test that would be great.

Please clarify carrier, whether phone is stock or not,whether has he done any file edits after the fact, etc.

Please confirm headphone model you are using if possible.
