Volume amplifier booster is really able to make your sound louder - it's not a volume controller, not a music player, it's a free booster app that enhances sound volume and enables you to experience as much loudness as possible.
If Volume Booster doesn't work on your device, make sure you don't have any other volume boosters or audio boosters, enhancers active. If that doesn't help, try using a different media
player.
Remember that Volume Booster works best with headphones!
DISCLAIMER: This app in no way can damage your phone!
