O.K. I've seen in different themes or roms that the backgrounds are different than stock. Evil eris the robot on the dialer screen was blue. I've seen em pink. Seen em with checkerboard pattern across his midsection. Never seen a completely custom without the robot tho. My question is how do you change that screen and is the robot not removable? Can I just put some random picture that I think is cool at the time? Oh and how do I change the color of the call button and battery icon, if theres a way without installing other apps to do it?
