Possessing an iphone, a Nexus S, a sony xperia play, the Galaxy S2 beats a flat seam, either at the rapidity of the brightness of the screen (iphone fact frown next) ,. ... one small criticism: it does not recognize the SD Card 32 GB I installed the applications to put it simply places it in its original 16GB of SD, by going against photos on map 32 GO ..... difficult to understand ... otherwise this is a very good device either on the phone level camera, GPS, VIDEOS, EVERYTHING IS PERFECT ... Well done Samsung!
