Buy a Samsung S Galaxy again June 20, 2011 in Puerto Rico. After three weeks without having had any accident with the phone, has not fallen, not wet, for no reason half of the screen was completely black, this problem permanecion and now I have to wait while I fix it I have to settle for a spare cell in the manufacturing (samsung) fix the defect. I'm very disappointed that since this is the first time I buy a phone so expensive and did not think it so quickly be damaged.
