ViPER4Android or V4A is one of the most prominent Audio mods for Android devices. In this guide, you will guide you on how to install ViPER4Android v2.7.1.0 on Android devices running Android Pie, Oreo, Nougat, and Marshmallow.


The Android ecosystem has been known for many things like the camera, but it is least recognized when it comes to the audio experience. Although some devices come with powerful and tuned audio, like the Galaxy S9/S9+ or Huawei P20 using Dolby Atmos. But what about the rest of the devices? Most of these devices are limited to utilizing standalone Equalizers or music player apps.

But if you have a rooted Android device, be it through Magisk or SuperSU, you have a decent chance of enhancing your phone’s audio through ViPER4Android. But before we get to the instructions to install ViPER4Android on your Android device, let us take a bit of time learning more about the new version of ViPER4Android, the features it offers, and changelog.

ViPER4Android v2.7.1.0 for Android – Changes and New Features

Surely, ViPER4Android isn’t something new. If you have been into the modding scene, chances are, you’d have heard of it at least once.

In brief – ViPER4Android is an audio enhancing software to provide a better audio experience on Android devices. It was founded by ViPER520 and first surfaced on the popular XDA-Developers forums by zhuhang in 2013 and didn’t take much time to gain a huge user base. Not just the speakers, but V4A also allows you to tweak the audio processed through headsets, Bluetooth, or USB.

For years, the development of the app has been constant, adding support for the latest Android versions as they are released. However, V4A development has been on halt since 2018 with the official v2.5.0.5 version support Android Nougat. With time, several community members including Zackptg5 and ahrion (Original XDA thread) took the liberty to carry on further developments and released a Magisk Module to help users install ViPER4Android on their device.

Around the same time, XDA members pittvandewitt and MrWhite214 (Original XDA thread) took the last open source version of the V4A audio mod (v2.4.0.1) and added all the new features from v2.5.0.5 to it. The updated version v2.7.1.0 also comes with a brand new Material UI that not only looks clean but also blends with the latest Android versions. The developers also rewrote the complete app in Kotlin, that helped in squashing a majority of bugs and fixed driver installation issues on the most recent Android versions. The latest version also adds support for Magisk 19.0 and above.


Before you install ViPER4Android v2.7.1.0 on Android Pie, Oreo, Nougat, and Marshmallow, take a look at the complete changelog below.

When your phone reboots, launch ViPER4Android FX and tap on the driver icon on the top-right side of the screen. This should display the current driver status. If it shows ‘Normal’, then the installation has succeeded. In case the driver installation fails (very unlikely), visit the F.A.Q section of the original XDA thread.

You can enable ViPER4Android audio processing and set different settings for individual modes. So go ahead, and give your phone’s audio a nice push and a chance to impress your ears.

So, this was our guide on how to install ViPER4Android v2.7.1.0 on Android devices running Pie, Oreo, Nougat, and Marshmallow. If you have any questions, please feel free to drop a comment.


  1. Could you please make detailed step-by-step guide for the S21 Ultra please? Beginning with the root and ending with successful installation of the V4A? Also It´d come in handy to see some package disabler or debload guide for this phone.

    1. Yes, that’s in the works as I write this comment.

      As for the debloat guide, I am thinking of making one that applies to all Samsung smartphones and tablets, rather than a single one that’s only specific to one device.

      The method stays the same, and it doesn’t make sense to write the same tutorial every time a new device is released. What’s your suggestion?

    2. Totally agree with you. In my honest opinion the best way to make it “all-in-one” and still keep it 100% viable is to make the guide versatile for all devices, but updating the package list separately. It´d be pretty time consuming I suppose but it will be great feature to reliably “copy paste” list and é voila, everything is done and safe.
      I´m a little worried (as a newbie) to do the debloat 100% right. But I suppose you will find a great way to explain it well enough.

      Lastly I kindly want to ask you to explain the basics in the first part (how it does work, if disabling package will make the app not work anymore [for more antitech people] ) and then proceeding to actual guide/tutorial and lists.
      Best regards

    3. Thanks for the suggestion. Honestly, it’ll be hard to provide a unified list that would work across every Samsung device, and their corresponding models or variants.

      However, I am thinking that I could provide one single list of all the known/common bloatware found on most Samsung devices, and then include a bit of instruction on finding package names of specific apps that one would want to remove. Something very similar to Step #5 of the Galaxy S20 bloatware removal guide.

      And yes, of course, I will give my best to explain all the aspects in the simplest and understandable manner possible. If you spot a mistake or have suggestions regarding improvements, I am always listening.

      Oh, and if you want, you can join the blog’s Discord server.

    1. Adam, which version of ViPER4Android did you download and use?

      The drivers install a corresponding Magisk Module, which could be the cause of the boot loop. The best way to confirm this and recover your phone from a bootloop is by using the steps in this tutorial.

      Let me know how it goes.

  2. I have a Galaxy S8 (SM-G950U) and I want to root it so that I can install Viper. However I cannot find a good way to root it. Could you give me some links on how to safely root my model phone?

    1. Hi Kishore. We do have a tutorial for the S8. However, it’s outdated. Can you wait a bit for me to update it? Or, I can give you a link to the XDA thread that can help you root.

    1. I have a Galaxy S9+ rooted and working properly.
      I followed the instructions above and I cannot
      get the “processing” to say YES, everything else
      in the driver status is good.
      open a mp3 song and I check the “processing”
      and it never says “yes” and it says “no”.
      The Viper4android has root permission in Magist
      and during installation it did say it needed drivers
      and and I clicked OK, the phone rebooted but
      the “processing” says “no”
      Please help!!!

    2. Hi. Have you turned on the ‘master limiter’ toggle for the sound mode you’re using? Like Bluetooth, Headset, etc?

    3. Just installed it via magisk and it is working nice with any audio player but it doesn’t work with videos…
      It has no effect on videos…
      Need help…

    4. Andy, that’s a known issue. In order to make ViPER4Android process audio from apps like YouTube, Netflix, Pandor, etc, you will need to install the ‘Audio Compatability Patch’ and ‘Audio Modification Library’ Magisk modules on your phone. Simply go into Magisk Manager > Downloads and install the said modules.

  3. Hi, cant this be done with out root? Like what we did with Camera2api like temporary root.. i dont want to root my phone so?

    1. Hi Sai. I am sorry, but no. Root is essential for ViPER4Android to work. Any specific reasons that are stopping you from rooting? And which device do you own?
