Oh well yes you can run it without rooting just type speedfreak .. works for me and about the background , i don't see anything white , but i do see that few icons are not clickable and 2 of them are not showing their full icon image , must be buggy .. The Speed Freaks homepage icon is half seen like broken kind of .( the one at the top left ) and the Users Button is too small to click Also another bug : After i click new run , after i finish doing the first test , the program just crashes and brings me back on to the desktop .
