It looks to have strict requirements and frankly if it's as bad as you say, time to forget it and start looking for something else.
I need to improve my Android device's audio quality then I found an application named Viper4android. I downloaded the tool from getviper4android.com but I am unable to change equalizer settings. What is the matter with the application? Please help me to resolve my problem. I followed all the instructions that appear on the above-mentioned website. My smartphone phone is Samsung Galaxy S5. Can someone help me with direct instructions or give me a trusted website that has included correct instructions.
