After update, calculator keys make clicking noise THAT CANNOT BE TURNED OFF. So far the only response from Samsung is to turn your phone volume off. Way to go, Samsung. So now I can't hear the sounds I WANT to hear like, you know, my phone ringing or music I was listening to as a "fix" to stop a noise that never existed before. Fix the problem samsung. Next phone will be an Apple, where they listen to the customer who PAID for the phone. Why did you even change this??? Unacceptable.
