Well, it's the sleepy start of a new week, and a new Samsung phone has managed to make an appearance in the wild to further distort the company's already confusing lineup of upcoming devices. A Samsung SM-G906A has been listed in the AnTuTu benchmark database – SM-G906 has been associated with the Galaxy S5 Prime, but the presence of a 1080p display in the benchmark listing suggests this could be another device as the S5 Prime is more than likely to feature a QHD (2560×1440) display. There's also the possibility that the display resolution is wrongly mentioned, as other specs in the benchmark – Android 4.4.3, 16MP camera, and a Snapdragon 801 processor – match up with the rumored specs of the Galaxy S5 Prime (though the S5 Prime might be powered by a Snapdragon 805 CPU upon launch.)
It's also possible that the SM-G906A is some other variant of the Galaxy S5 – for now, we'll have to be on the lookout for more info on the matter, before we can paint a clear picture of just what is going on in the development wings of Samsung.
