Try this new style volume booster. It will increase your speakers volume up to 10-20%. What sets Volume Booster Black Edition from other similar applications is that when a user activates boost this app not only amplifies the sound to the end, but also uses the built-in Android equalizer to optimize the frequency channels by means of a special algorithm. So the result is a stronger and clearer sound. * Enable or disable Volume Boost from active notification (android 4.1+) * Control Volume Boos
