Google Search

Da come si può vedere la maggior parte dei cambiamenti riguarda più che altro la versione base di android, che ha poco a che fare con i firmware originali della Samsung.

Ricordiamo che Android 4.2 è atteso anche per i Galaxy S3 e Galaxy Note 2, mentre rimane in dubbio per i Galaxy S2 e Galaxy Note.
In ogni caso considerate le novità apportate non sarà una grossa perdita.
