Samsung - CES 2014 - Galaxy Press Logo - 006

If you're holding out for the Galaxy S5 release you may not be waiting much longer. Samsung's next flagship smartphone announcement could come as soon as Feb. 23, though the device may not hit the market until a few months later in late April.

The latest Galaxy S5 rumors come from Eldar Murtazin, a technology journalist who's also know for leaking mobile news himself from time to time. Murtazin even goes as far as to predict the exact time and place of the launch even, claiming Samsung will hold a press event at 6 p.m. on Feb. 23 in Barcelona just ahead of Mobile World Congress, which kicks of on Feb. 24.

Under the hood, the Galaxy S5 is expected to pack all the latest components, including a Snapdragon 805 processor, a bigger display and a more powerful battery. The device is also rumored to feature some kind of biometric security, and we've heard conflicting reports pointing to either fingerprint or eye recognition technology. As for the design, we're expecting the Galaxy S5 to sport the same old plastic shell along with the faux-leather backing first seen on the Galaxy Note 3.

Murtazin also references Samsung's new user interface, which leaked yesterday showing a modified version of Android that takes its influence from both Microsoft's Metro UI and Google Now. The new software could also be a version of the company's Magazine UX adapted for smartphones, though we won't know the full story until the device is unveiled.

TechnoBuffalo will be in Barcelona covering Mobile World Congress next month, and we'll be sure to keep you updated on any news surrounding the Galaxy S5. Stay tuned.
