The Samsung Galaxy S5 rumor tide is slowly but steadily turning, as fresh sources seem to debunk all the speculation about aluminum build while giving increased credence to built-in fingerprint scanner.

Samsung Galaxy S5 Analyst predicts two Samsung Galaxy S5 plastic versions with fingerprint recognition

Remember when Galaxy S5’s specs and features were “confirmed” by otherwise credible insiders? It looked like the end of the road for the gossip bonanza, especially as an ETA was soon after tipped by a fairly believable rumormonger.

But it couldn’t have been so simple. Thus, the March deadline became February… again, with a recent Tizen-centric story throwing it up in the air and pushing us back to square one. There’s no way Samsung intends to update the world on Tizen development and debut the GS5 at the same press event, so March it is after all. Or maybe April.

Meanwhile, an investment analyst by the name of Ming-Chi Kuo insists on muddying the waters in the hardware and design departments, suggesting the GS5 is to be built of familiar plastic in the end and pack 32-bit power.

First things first, plastic? No problem, as long as a metal option is coming too. But apparently, it’s not. Kuo claims both the “Standard” and “Prime” versions rock “polycarbonate” exteriors, which is bound to enrage a fair share of Samsung aficionados in love with the “premium” builds of competitors HTC One or iPhone 5s. Drive them to jump ship? Guess only time will tell.

Moving on to what’s allegedly beneath the hood, forget about 64-bit Exynos 6 CPUs. Or Snapdragon 805. The Prime S5 is tipped to run on a 32-bit octa-core Exynos 5430 platform (“true” octa-core, hopefully), whereas the Standard next big thing should go official in Korea with a Qualcomm MSM 8974AC (aka S800) and worldwide with either the 8974, or another Samsung homebrewed 32-bit octa-core chip, the Exynos 5422.

Technical mumbo-jumbo aside, it means the S5 will likely only be a tad zippier than the S4. And possibly, behind the iPhone 5s in raw speed.

To make matters worse, the Standard S5 might come with 2 GB RAM in tow. And “modest” Full HD resolution. Good thing the Prime packs 3 GB RAM and a 2,560 x 1,440 pix res (aka Quad HD, QHD, 2K or WQHD) 5.2-inch display. Also, both “siblings” have upgraded 16 MP snappers slapped on their backs and beefy 2,850 mAh batteries inside.

As for fingerprint support, they’re both tipped to carry it, but the question is whether people actually want the gimmick feature. Better yet, would you give it up for an aluminum unibody? How about a 64-bit SoC?
