The geniuses at Samsung decided to add annoying clicking sounds to the calculator that you can't turn off. Instead of fixing the issue, the developers are telling people to use a stupid work around where you turn off the system sound. I don't want to do this because I want my phone to make a noise when I plug it in to charge in case my charger has come unplugged, and I don't realize it. This has happened to me before. Every one should rate this one star and swap to the Google calculator.
