Th three colored-dots at the bottom of the screen?
What do they mean, represent? Or just for show?
I think they're just there for the show, or potentially a harmless bug. The mystery dots appeared in Windows Phone 8.1 when the touch settings were upgraded to gestures and touch. In phone coming pre-installed with Windows 10 Mobile, they appear after upgrading the gestures and touch settings app to version number 2.3.0.7
