Rumors of a successor to Samsung’s highly popular Galaxy S have been going around for a while and now Samsung has used its Samsung Unpacked events to drop a teaser of the upcoming successor to the Galaxy S. The teaser itself doesn’t reveal anything, but the company promises “something big” on February 13th at 6PM, which is just a day before Mobile World Congress 2011 and Valentines day. What features do you think that the Galaxy S 2 (or whatever it may be called) will feature? We’re dreaming of the usual improvements such as a newer version of Android, higher resolution display, better camera and increased storage space and battery life.
