Samsung’s next-generation Galaxy S5 will feature a 2K QHD display and iris scanning technology, and it will get its grand unveiling at Mobile World Congress next month, an unnamed “tipster” has claimed. Samsung is expected to maintain the plastic form factor we’ve seen from the rest of its smartphones, concentrating on improvements internally instead.

Last week a series of screenshots were posted on Twitter indicating that Samsung’s in the process of working on a major design overhaul for its famous TouchWiz user interface which gets plastered over the top of the traditional Android OS on all of its current smartphones. Today, two new screenshots have emerged showing what appears to be an informative card based UI, similar to what Google created with Now.

Samsung’s already told us that it’s hoping to bring iris-scanning security features to its upcoming Galaxy S5, but that may not be the only innovation the flagship handset introduces. According to some sources, we can also expect a new high-capacity 2,900mAh battery with rapid charging technology.

Earlier today, we revealed that Samsung is expected to unveil its flagship smartphone of 2014, the Galaxy S5, in London sometime around mid-March, and not at the Mobile World Congress in Barcelona next month as previously rumored. Now a Samsung-orientated publication has posted a list of ‘confirmed’ leaked specifications on the internet stating some of the impressive internals the device is purported to pack.

The Samsung Galaxy S5 will get its grand unveiling at a press event in London in mid-March — not at Mobile World Congress in Barcelona next month — according to a “reliable source.” The device is expected to debut Samsung’s new iris scanning security feature, as well as an improved design made from more premium materials.
