Simple and small app to boost your speaker or headphone sound volume. Useful for movies, audio books and music.
Volume Booster GOODEV App for Android
Volume Booster GOODEV
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 (but it may be too late).
By installing this app, you agree not to hold its developer responsible for any hardware or hearing damage, and you use it at your own risk. Consider this experimental software.
Not all devices support this software. Try it at your own risk and see if yours works.
This app does not work on most Android 4.2.1-4.3 devices. It should work on Android 4.4 and above, as well as devices below 4.2.1.
It’s not for adjusting the speaker volume in phone calls (which has its own boost I think), but for adjusting the volume of music, movies and apps.
When you set boost to zero, the volume booster is disabled. The notification icon serves only to facilitate the launch. If you don’t like seeing the notification icon when Volume Booster is off, just go to Volume Booster Settings and set it to show only when Volume Booster is running.
