Navigation voice not loud enough I have a Galaxy S and I love using my navigation app. The problem is she isn't loud enough. I think I have the speaker turned all the way up. Is there way to make it louder? It's a straight talk if that matters.
There are sevelar volume booster available on the Google Playstore, as e.g. Speaker Boost or Volume Booster (for more alternatives, try this search). You might want to give one of them a try.
