This is a brand new Samsung Galaxy A5 2017. It was sent to me a few days ago replacing a defective one. My issue is this: when I call someone they can't hear me due to the phone sounding like I'm rubbing it over paper or material. I never had this issue before and defective cell worked in my apartment without this issue. So I know it isn't the reception. When I call them on my landline they tell me it's like I'm putting dishes away or rattling something. And they also hear their voice echo when they talk.
