How do I get the volume to go up when I am talking on the phone? besides side volume/settings

[AC Question]

I can't hear on phone calls and even my radio/ media isn't that loud...But really need it louder for phone calls. I have used the volume on the side and gone into the settings on sound. Is there another way or to increase what the factory setting is?

Welcome to Android Central! Which phone? In general, you can't boost a phone's native maximum volume. Check to see if the earpiece speaker is obscured by any debris.
