Samsung also cited the Vlingo voice activation feature in the Galaxy S II, while noting the Siri system in iPhone 4S remains in its beta phase.
The Siri feature in the iPhone 4S still requires activation by hand and can't support hands-free as the Galaxy S II can, according to officials at Sensory, whose hands-free activation technology is in the Galaxy S II.
Samsung also noted the $199 starting price for the Galaxy S II includes 16GB internal storage and up to 32 GB external storage.
The $199 iPhone 4S is a 16GB model with no external storage.
