These news came from one of the presenting offers of Samsung and published on PHANDROID website and here is the New Specifications :

1,8 GH dual core processor

2GB rams

4, 6 SUPER AMOLED PLUS SCREEN

12 MP camera

As you can see the device has little changes in it is shape so that Samsung avoid any legal issues with APPLE so they made small changes up and down , Samsung galaxy s3 is the heir of galaxy s2 which is the most successful devices of Samsung it is also came at the top 10 smartphones in 2011

There are no further details about the date of launching but it seems very close (by the beginning of the new year) and it is worth to mention that the new device will work with ANDROID system ice cream sandwich which is very brilliant choice

If these rumors true the device will be very promising but it seems little big for a phone specially that Samsung has already created Samsung galaxy note so I hope that Samsung keep using galaxy s2 screen which seems really big
