After the latest update, my front speakers barely have any sound anymore. I have my volume set at max and the little bit of sound that comes out during a call or on speakerphone comes out of the back of the phone now. I never use to have to have the call volume set past midway on the settings before and now, even at maximum volume, I can barely hear the person on the other end! I have taken the battery out, and tried changing the volume in the settings menu and also during a call. The volume will go down but I can't hear the person on max. What happened? And how to I fix the volume issue? Thank you!
