Galaxy S5 Calls

[AC Question]

Out of the blue, my galaxy s5 screen looks different went I get or try to call someone. Instead of sliding a green or red icon, I have to press the rectangular icons. Itr also tells me who I'm recieving a call from before my ringtone. The in call screen also looks differnet and I cant find the keypad either. Help please
