With the Galaxy S4's launch on the horizon, Samsung may be prepping another phone — this one a successor to the Galaxy S III mini. Leaked images posted at SamMobile appear to show a phone with the same design language as the Galaxy S4 but a smaller form factor, just as the original mini was a copy of the Galaxy S III. Its model number is shown as GT-I9190, compared to the S III mini's GT-I8190. SamMobile says the device has a 4.3-inch screen, compared to the 5-inch screen of the Galaxy S4 or the 4-inch screen of the S III mini. 4.3 inches was once enough for Samsung's flagship Galaxy S II, and there's still obviously demand for phones with smaller screens than the S4.
