I have an old android phone and the volume is often low when I'm doing voice chat using various apps. Is there a way to amplify audio within android? I have an old phone.
Or should I buy a new phone or an amplifier? My current phone's getting quite old too.

In my smartphone this just amplifies the surrounding noise. Is this because I have an older Android version?

Just use Bluetooth speaker or use your computer or laptop speaker using Bluetooth. Or use headphones. Why you want to amplify loud speaker or your phone. It will go kaput
