True to its Project Zero codename, the Samsung Galaxy S6 is reportedly making quite a U-turn on release date this 2015 by amply delivering on killer functionalities unseen before and a device build worthy of being a premium flagship.

Eyeing to recover lost grounds, no thanks to the relatively dismal reception generated by the Galaxy S5, Samsung appears to be ditching its stock smartphone templates and opting for a reboot with the GS6.

The handset, once out of the box, is a totally different Galaxy breed, if reports are to be believed.

Metallic finish

A report by The Verge pointed to images that were provided by French tech blog site, which suggest that at least on the outer shell the S6 is far from a refresh - it is in fact a complete overhaul of Samsung's design language.

It seemed that finally, the South Korean tech giant is taking cue from Apple and HTC and will bring out the Galaxy S5 sequel wrapped in metal chassis. Such possibility is not very remote as The Verge noted that Samsung has started early on to the metal device pathway via the Galaxy Alpha, the design and built of which puts it in a direct collision course with Apple's iPhone.

It goes without saying that the Galaxy S6 blueprint is all mapped out for a showdown with the tech world's current toast - the iPhone 6.

Killer features

And in order to slug it out with Apple's hero phone, the Galaxy S6 will have to impress big time so the upgrades packed with the upcoming device are implemented inside and out.

According to a Forbes report, the next Samsung flagship will represent the company's "radical U-turn," in the smartphone market and among the changes that Sammy and Android fans will surely appreciate is the elimination of bloatwares.

While the GS6 will remain TouchWiz-skinned and quite far-off from becoming a vanilla Android device, users can expect "a dramatically streamlined TouchWiz will debut on the Galaxy S6," added the Forbes report.

The publication pointed to Reddit user SamsungRep2015 as source of its information.

The same adjustments will lead to a Galaxy S6 that is snappy and RAM-optimised.

"Overall device responsiveness is vastly improved, and memory consumption is way down ... Some builds have freed over a gig of memory consumption from cold boot," the Redditor was reported by Forbes as saying.

Also, SamsungRep2015 echoed earlier claims that the Galaxy S6 will boast of a 64-bit Snapdragon 810 chip that is paired with 3GB of RAM. The 5-inch plus screen profile will join the 2K resolution club while the main snapper will sport a 21MP camera.

It is wildly rumoured that Samsung will uncloak the Galaxy S6 this week, using the 2015 CES in Las Vegas as platform with the likelihood that release date of the device will follow in the immediate weeks ahead.
