So I go To The Verizon Store Because My Call Quality Sucks Big Time (Cutting In And Out). So The Guy Helping Me With My Phone Does Some Test Calls And Surprise, Surprise, It Wors Fine. He Then Says To Me That The Reason Why I May Be Experiencing Problems Is Because I Don't Have ATK Installed In My Device And Installs It For Me. I Told Him I Already Used ATK And Uninstalled It Because I Felt There Was No Need. But That Left Me Confused. Is All The Apps Running In The Background Making The Call Quality Lower? That Doesn't Seem Right.
