Mobile World Congress 2014

China's Gionee brought what's claimed to be the world's slimmest smartphone to MWC in Barcelona, Spain, this week. The 5.55 mm thin Elife S5.5 features a Full HD AMOLED display at 441 ppi, is powered by an octa-core processor and has a battery that's reported to last all day with heavy use.

Finnish company Creoir Ltd is certainly banking on style being the force to drive mass market appeal of the smartwatch. Its concept Ibis Dual Face Smart Watch on show at this week's Mobile World Congress closer resembles a piece of jewelry than other smartwatch designs floating around.

Yota Devices has announced a new version of the of the YotaPhone. The YotaPhone 2 features a larger electronic paper display with full touch control, as well as an improved AMOLED color display and the Android OS.

Apparently those two new Galaxy Gears that Samsung announced the other day weren't the entire story. Today the company announced its first fitness tracker, a wrist-based device called the Gear Fit.

None of the devices at this week's Mobile World Congress are likely to draw nearly as much attention as the one Samsung just announced. After months of rumors, the Korean company's 2014 flagship smartphone is now official. Meet the Samsung Galaxy S5.

Just months after launching the Z1, Sony has announced its latest flagship smartphone, the Xperia Z2. The handset, which largely shares its design with the older model, offers improved screen technology and a focus on optics.

Fujitsu has developed a glove-style device for workplace use that provides touch and gesture-based functionality for site operations.

China's ZTE is the world's fourth-largest smartphone maker, although it retains a low profile in North America, much of Europe and other big markets. That could change very soon as the company rolls out a few big new phones in the coming months.
