Hello,
It looks like device detection does not reconize safari version 4.8.1 for linux. User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.34 (KHTML, like Gecko) Qt/4.8.1 Safari/534.34. Also, why are there not any images for Mobile Safari and Chrome Mobile iOS
Finally, because device detection does not reconize the safari version, it messes up the browsers graph. I have two listing of Safari in my table view. It should group all safari browers together when it is in brower mode.
