I dont believe it does
There was a rumor that the Focus S has the same camera as the Galaxy S II but I believe this is a falsehood. It has the same camera as the Samsung Infuse 4g, which is also a US only release. Both the front and rear cameras of the Focus S and Infuse are identically spec'd, even down to the 720p recording, and the Infuse had no Backlit sensor (galaxy s has 2.0 front cam, 1080p and BSI)Makes sense to me.You can compare both phones on samsung's site.
