Does this work With Android 5.0

I'm wondering if this works with android's latest version (Excluding the previews) Does this work with Android Lollipop LRX21P?
[Android Q&A, Help & Troubleshooting] brunoperissotti:
I usually try to find my way around these things, but I have no idea what to do...

Moto X 2014 (XT1097) 6,0. Stock rom. Root method by modified kernel (available at motoxbrasil).

Busybox Free, SELinux permissive.

Viper4android works with force enable, driver status shows OK and sound is enhanced... for a few seconds, then sound goes back to normal, driver status shows processing: no.

And when I pause and tap play again in whatever media player (YouTube, Spotify, PocketCasts) I'm using, the driver is working again, only to stop processing seconds later.

2 days ago everything was working good even with musixmatch and google play music. The sound was amazing. I was completely blown away by the sound. But from yesterday i am facing problems.
[Android Q&A, Help & Troubleshooting] mer2329:
Can you try one of the following

1) try another pair of headphones with your android, if it sounds better it's your headset

2) try the headset on another phone, borrow a friend's or neighbors. If it sounds the same it's your headset.

3) if it's a headset with a normal headphone jack (3 contacts. No mic of in line buttons) try it on your computer or another device. If it sounds the same it's your headset.

4) if you have a adapter (trrs to trs) you can use it to test it with any device. If it sounds the same it's your headset.

While disabling v4a, no glitches, no distortion, and no bass at all. Without v4a its working as all oneplus 2 with oxygen os 3.0 is working. And yeah my earphones are perfect. Tried nearly 3-4 headsets, all same
[Android Q&A, Help & Troubleshooting] mer2329:
Im leaning towards an oxygen issue.

I've helped other 1plus users and none have been able to get it working on oxygen.

They all got it working on other non oxygen based roms.

This is where I stop helping you. You can do the suggestion below, ask on the 1plus forums, or hope someone else here can help you.

My final recommendation is the following.

1) do a full recovery backup. (save this backup in case it Viper dosent work

2) install cyanogenmod

3) Enable developer options

4) in developer options enable root for apps

5) depending on the build install busybox (to system/xbin) and SELinuxModeChanger. Skip busybox if your rom comes with busybox.

6) Install and setup Viper.

7).setup your media players, I can help you set up your media players once the above is done.

Does this work with hTc 10??
[Android Q&A, Help & Troubleshooting] mer2329:
The Viper apk is device independent.

While some viper zips are device/rom dependant

The only 2 limitations I know of are

1)1plus devices using oxygen won't work unless you install a different rom. As oxygen is incompatible with Viper.

2) Your device needs to be a neon device to get the full benefits of Viper, non neon devices can still use Viper.

Use the apk linked by the OP. And I consider the zips to be a last resort.

Hi folks

I've been trying to install v4a but always fail to activate it.

So.. I am using a g3 stock mm 30d rooted.

When I install it I run an update which finds another version with red icon.. The old one with the blue icon is enabled but the new one cannot be enabled. Which one do we have to use.

I am using poweramp for music.

Can you please assist? Many thanks

[Android Q&A, Help & Troubleshooting] mer2329:
Did you setup Poweramp?

With Poweramp you need to disable it's internal processing.

In settings disable direct Volume Control

Although the following is not needed I still recommend it

In the equalizer disable "equ"

also it can't hurt to disable "tone" and "limit"

If your still having problems use an app like titanium backup and freeze music fx, and any to the fx system apps on your phone.

Most zips install Viper as a system app.

You can manually uninstall other use an app like titanium backup to uninstall.

The following assumes that Viper is installed to /system/app.

To manually in install Viper navigate to /system/app and delete the Viper4android apk.

Now reboot the phone

If Viper is still showing up as a app it should be a user app and should be uninstalled using normal methods.

Edit: then I say oxygen based it means that the rom is a fork of the oxygen rom.

Please post a link to the hydrogen rom release thread.

Edit 2: in extremely simple terms a fork is using mush of the same code as the original. As such a fork can contain the same bugs as the original.

Some Examples of code forks

Palemoon is a fork of Firefox,

Google Chrome is a fork of chromium

Linux mint is a fork of Ubuntu.

Libre office is a fork of open office.

Edit3: I found a release thread, however there is no link to the source code, or a reference to oxygen. I'm guessing it's oxygen based.

I would suggest switching to cyanogenmod or cyanogen os

To install the driver you need the following.

1) Before starting you need to disable the knox binary http://xdaforums.com/nexus-6p/general/guide-installing-viper4android-t3250579

This will have the following impacts on your device, your knox bit will be flipped, you will not be able to use secure Samsung apps (like Samsung pay)

2) If your on lollipop or marshmallow you will need SELinuxModeChanger

3) a working version of busybox, use either stericson's or meefik's.

Search busybox on play.
