Volume Booster GOODEV App
Is your mobile phone sound bad? When the song is done, it is quiet. Not good when calling. Then you have to use this Volume Booster GOODEV app.
I have been using this app for a long time. I think it’s important to you too.
This is small, free app to boost your speaker or headphone sound volume. Useful for movies, audio books and music.
Use at your own risk. Playing audio at high volumes, especially for a prolonged amount of time, can destroy speakers and/or damage hearing. Some users HAVE reported destroyed speakers and earphones.
If you hear distorted audio, lower the volume
This app does not work on most 4.2.1-4.3 devices. It should work on 4.4 and higher, as well as on devices below 4.2.1.
