The Samsung Galaxy S5 won’t arrive until next year, but anticipation for the purported gadget is just starting to heat up. Fans who want the to get their hands on the next Galaxy smartphone may not have to wait too long if one current rumor is true: the Galaxy S5 could arrive as early as January 2014.

Samsung Galaxy S4 sales

The reason behind that rumor is the waning sales of the S4, however that notion was dismissed when JK Shin (chief executive officer for Samsung) claimed there were over 40 million Galaxy S4 units sold to date. That would make it the best-selling Samsung smartphone as of yet. The total sales for the Galaxy S3 were 50 million, and now the S4 is poised to take over.

It’s predicted that Samsung will unveil their next generation flagship phone in January. It’s also predicted that the new phone will have new features and software. Fans are hoping the Galaxy S5 will feature a metal chassis rather than a plastic body. It’s been said that while the Galaxy was designed for longevity, most users feel the build quality is lacking.

Will Samsung solve this issue? VR-Zone.com explains, “It has been theorized that the Galaxy S5 chassis will be built in a Samsung facility in China, and that testing is currently underway to figure out logistics of building such a device.” Another hardware change, and a major one at that, might be the inclusion of a flexible screen.

Devices with flexible screens have been announced by both Samsung and LG, and while the first offerings are more or less designed to gauge user interest, it is a likely theory that the Galaxy S5 would come with a 5.5-inch flexible OLED screen. Another rumor suggests that the Galaxy S5 would feature a regular AMOLED 5-inch screen with a resolution of 2,560 x 1,440 pixels, which gives it a pixel density of 560 ppi.

Gotta Be Mobile’s Adam Mills predicts the Galaxy S5 will feature a 16MP camera sensor with ISOCELL technology for improved low-light photography. However, he’s not certain if Samsung will opt for metal over plastic with the next phone. Tom Smith for Christian Today speculates the Galaxy S5 could be introduced at the Mobile World Congress event in 2014, which will be held in February.
