Samsung Galaxy S II it is by far the strongest competitor for the iPhone 4 which has been available on the market for 1 year. Those from Samsung have built a smartphone with a 4.3-inch screen and a dual-core processor that should be at least 2 times faster than iPhone 4 but from the tests above it seems that the difference is not really that big. When browsing the web, iOS loses without a right of appeal in front of Android OS, which loads pages faster and now displays the content without lag when scrolling or pinch to zoom. Regarding the games, it seemed quite strange to me that everything loaded faster on the iPhone 4, even though we are talking about inferior hardware to that of the Samsun Galaxy S II.
Apple has to produce a dual-core iPhone 5 with a bit more RAM if possible because the smartphone market has moved to the next level and the iPhone 4 is currently one step behind.
