The second leaked phone looks very similar to the Samsung Galaxy Mini, and we don't know anything about it except for its model number, which is S5670 (the Galaxy Mini is 5570), and its name - the Samsung Galaxy Suit.
If these devices are of any indication about Samsung's future plans, then the Korean manufacturer may be willing to embrace the mid and low-end Android market - after all, Sammy has already released phones like the Galaxy 3 and the Galaxy 5. It's almost certain that we will know more about these handsets when MWC takes place (between February 14-17 in Barcelona). As with CES, we will be there to inform you about everything worth mentioning.
