Volume Booster GOODEV for Android

Overview of the app

Volume Booster — GOODEV is a small utility for Android that raises the loudness of your speakers or headphones by roughly 20–30%. It’s commonly used to make movies, music, and spoken-word content easier to hear, and it includes a built-in equalizer so you can fine-tune the output. The application is free and available on the Google Play Store.

Core capabilities

• Lets you increase speaker or earphone output by about 20–30%.
• Includes an adjustable sound equalizer for custom tone shaping.
• Distributed at no cost through the official Google Play marketplace.

Critical safety notices

• Prolonged playback at the app’s highest boost setting can permanently harm speakers and damage hearing; several users have reported such problems.
• If you hear clipping or noticeable distortion, reduce the volume immediately — continuing could make the damage irreversible.
• Before installation you must accept that the developer is not liable for hardware failures or hearing-related injuries.

Usage tips and behavior

• Avoid using this tool to amplify the earpiece during phone calls; system-level call audio already has its own amplification and this app is not intended for that purpose.
• Setting the boost control to zero effectively disables the app’s amplification, but it may still push notifications unless you change the notification settings.
• You can restrict alerts so they only appear while the app is active by adjusting the notifications option inside the app.

Conclusion

Volume Booster — GOODEV can noticeably increase perceived loudness and offers equalizer controls for a better listening experience, but it carries real risks to both hardware and hearing if misused. Proceed only if you understand and accept those risks.
