Change caller display from black to white

[jorgecue8]

Hi, my sister and I are new to android and both got the Samsung Galaxy S5. The thing is I live in Mexico and bought it here and she lives in the US and bought it there and I noticed whenever she receives a call the color it displays is white while mine is black. Is there any way to change this colors in the caller display?

Welcome to Android Central! What version of Android are you on? Are you still on 4.4.2? 4.4.3 brought a new dialer app (at least on vanilla Android, like on the Nexus devices), which changed the background from black to white. Your sister may be on 4.4.3 while you're still on 4.4.2.
