If it wants to retain its massive share of the smartphone market, Samsung must ensure its flagship devices are always one step ahead of the competition. So with the Galaxy S5, the South Korean company hopes to take on Apple’s Touch ID with eye-scanning technology that’ll let you unlock your phone using only your irises.

The device will be available around March or April of this year, Samsung executive vice president Lee Young Hee confirmed in an interview with Bloomberg — and it’ll launch alongside a second-generation Galaxy Gear that’ll be thinner than its predecessor.

Samsung appears to be working on a major overhaul of its TouchWiz user interface for Android. Leaked screenshots of the new interface — which sports a new lock screen and colorful new icons — surfaced on Twitter today, and it’s though this year’s Galaxy S5 could be the first handset to get it.

Today, the Head of Design at Samsung Mobile, Dong-hoon Chang, has allegedly confirmed in an interview with a South Korean publication that the company will unveil its upcoming flagship smartphone of 2014, the Galaxy S5, at this years Mobile World Congress, which is scheduled to take place in February.

Samsung Taiwan posted a rather clever video on its official YouTube channel, two days ago, teasing a new device that’s advised as “coming soon.” The South Korean company labelled it as simple, elegant, fast and fit.

Samsung’s flagship Galaxy S4 might be just 7 months old, but rumor has it the South Korean company is already planning to launch its successor in the first quarter of 2014. During the same three-month period, it’s also expected to unveil a Galaxy Note 3 “Lite” and a number of entry-level devices, according to sources familiar with the company’s plans.
