The Samsung Galaxy S II is the company’s first dual-core Android handset that is due to launch imminently. It comes with a 4.3-inch Super AMOLED display and is just 8.49mm thick (the arc is 8.7mm at its thinnest point).
Mobile-Review has the first part of its Galaxy S II review up and there are some pictures comparing the handset against the Xperia arc. Both look similar in size although the Galaxy S II is wider. There are also some shots comparing the displays, which shows the Galaxy S II has better contrast, but with the arc at more of an angle it’s certainly not conclusive.
