A Galaxy S4 variant with model number GT-I9507 has been known to exist for some time, first showing up on Picasa and then later on benchmark site GLBenchmark. Now, another confirmation of the device has arrived via some UAProf (User Agent Profile) strings on Samsung's mobile website, which mention GT-I9507.
Expected to be a carrier or region-specific variant, the display resolution is mentioned as 1920 x 1080. However, one discrepancy in the UAProf is the processor frequency, which is clocked at 1.4GHz. It's probably non-final though, so we can expect to see it use a Snapdragon 600 or 800 chipset when it launches, and maybe even the Exynos 5420.
What do you guys think the GT-I9507 will be?
