Mere days before Samsung unveils its newest phone, a Chinese forum post has offered some purported shots of the Galaxy S IV. Now it's worth mentioning from the outset that Samsung plays a good game of subterfuge- -- it masked the Galaxy S III ahead of its reveal last year in a blockier plastic frame and it could be that this phone, with a very Note-esque face and outline, is also a filler ahead of the final reveal. It could also be yet another phone that will slot in elsewhere in Samsung's ever-expanding Galaxy family, or even a Shenzhen knock-off that's jumped the gun. However, with that said, there's still plenty here to muse on. The shots appear to be taken in a phone unlocking shop somewhere in China, with this GT-i9502 model apparently bound for carrier China Unicom. Interestingly (at least for a flagship), it appears to be a dual-SIM version, with the mono-SIM version apparently picking up model number GT-i9500 -- a number that would fit in with the series so far.According to the leak, it's running a fresh version of Android (4.2.1) with a 1080p display (no word on dimensions just yet), 2GB of RAM and a 13-megapixel camera on the back.The mention of a "5410" CPU suggests it's Samsung's Exynos Octa chip powering it and while AnTuTu might only recognize that as a quad-core chip, we noted during ourhands-on with the new chipset that only four cores were being used at a time. We're still hoping Samsung's final design pushes the envelope a little further than a repositioned camera sensor and a new glossy texture -- we've added a shot of this after the break. Rest assured, Jeremy will be letting us in on the big secret later this week.
