Mono version for both speakers?

Is there a version of this mod that outputs mono on both speakers? I like the utilization of the top speaker, but don't like the stereo between the top and bottom.

I second that. Such a mod would make my device complete. This state can be reached by switching the device to mono in the ui options but that is as unhandy as having to turn off the cutout in the developer options on LOS just to watch YT normaly.

Just wanted to give a belated thank you for this MOD. Didn't know I've been using it for years. I just flashed it over my ROM of VS99520d for the LG V20. I know I'm crazy but I swear the music is more balanced and dynamic coming out of the headphone jack compared to stock. A big improvement in the highs especially. I doubt I'd notice any difference in regular Cans, but I'm convinced it's better in my Sennheiser HD800.

    Any donations will get you my social app for free.
    It will be on the Play Store soon. However if you donate PM me with your donation info and I will send you a copy for free.

    Credits first off to my friend Freeza for which this mod was based off of. He gave me the go ahead to use and moddify any way I like.
    This is the result.

    I understand there are many files here but I like options.
    Trying to support as many V20 variants as we have.

    This is tested and works flawlessly on my Sprint LS997. This should work for all variants but this is made from latest firmware updates ZV7.

    This is something I have been working on for a few days and have now got it Perfected.
    I bring you Stereo sound via Front and Bottom firing speakers. Lowered volume to help protect your expensive device.
    I bring you Quad Dac high impedance mode when HiFi is enabled.
    Enjoy the full audiophile experience.

    Hit like if this helped you out.

    Unzip the file. Place it in root of internal storage in folder System/etc. Set permissions, turn device off then power back on.
    That is all.

    After setting my device up again I am pretty sure I found the problems some had as I had them that time.
    Found and fixed the problems. Hifi really FORCED with Stereo.

    If you are on older firmware, try this file.
    It doesn't work on my updated firmware as it is based on my friend Freeza's older firmware update and modded further by me.

    Sorry, I haven't been in much.
    My wife had brain surgery and following Grand Mal seizures so it has been rough.
    I posted to my YouTube channel just now about it. I will start my mods, social app and video reviews back up shortly if things keep improving.
    That's where I have been.
    Any app donations could really be used right now as she is out of work.
    If you donate remind me and I will send the app. Once it goes live with updates on the Play Store I will send keys to all donations.
    Thank you for your help.
    If you pray send them our way.

    My wife is having bad seizures today.
    All files should be labelled correctly.
    The thread describes each file.
    I will get back as soon as my wife is feeling better.
    Until then others here will probably jump in to help.
