When you call granny, does she keep saying "Huh?! Wut?!" or does the conversation flow pretty well? Rate this thread to express how you feel about the Sony Xperia XZ Premium's call quality. A higher rating indicates that calls are clear and crisp, and that regardless of background noise, you can hear the other party clearly (and with ample volume) and they can hear you.
