FAQ:

Question: Why not use the Playstore version?

Answer: It's not officially maintained by the Viper4Android devs, this is easy and secure and up to date.

Question: Why do i need the SELinux Changer application?

Answer: Our firmware comes with SELinux mode ENFORCING, which does not allow Viper4Android the permissions it needs to install properly and installation without this will result in only the Viper4Android app working and making no changes to the sound quality as the sound driver fails to work. What this app does is change the mode to PERMISSIVE, which gives it the permissions to install properly so the sound driver installs successfully.

Question: Can i uninstall SELinux Changer application after installation?

Answer: No, the sound driver will fail as soon as you remove it, as it goes back to ENFORCING mode.

Question: I followed the instructions but i still did not notice any sound improvements?

Answer: Try rebooting and wait a couple minutes then open SELinux Changer and make sure it has root access and select PERMISSIVE and make sure It's on by closing and opening it and reboot and try again

*Reinstall the sound driver

*Make sure you tick Enable Viper4Android in all the tabs if you don't know which one your audio is played through and just to be sure

*Post in the Viper4android thread
