There are many features in galaxy features which you can use and enjoy fun. The bar where you have the option of WiFi, Silent, mobile data which can be open simply by dragging it down it present over there you need to just click on to it, it will get activated. If you want to check it has been activated or not open any page and then scroll it down just by waving your hand on to it.
