My wife may have messed up a setting if there is one, because all of a sudden, she can barely hear the caller when holding her phone to her ear. It works fine when on speaker though!
Lol wow really be a jerk and get lots of help. Maybe you should put all the info in your post instead of us assuming you have a clue on how to use your phone. You wouldn't be the first person that didn't know about the volume buttons.
