If you've lost track of the specs found in Samsung's latest smart devices, the company has released a couple of hands-on videos to show them in action.

The videos detail the devices Samsung unveiled back at the Mobile World Congress (MWC) 2014, showing off the new Galaxy S5 flagship smartphone, as well as the Galaxy Gear 2 smartwatch and the Galaxy Fit smart band (no Galaxy Gear Neo video).

Samsung Galaxy S5 Hands-On Video

The new-generation Galaxy flagship smartphone from Samsung has stirred some mixed reactions. While some are praising the improvements it brings over its predecessor, others are bashing Samsung for its lack of design innovation, considering the new iteration a downgrade in terms of aesthetics and build quality.

The new Samsung Galaxy S5 is definitely superior to its predecessor, boasting a powerful quad-core processor clocked at 2.5GHz, a larger 5.1-inch full HD display, a 16-megapixel camera with lots of advanced features, a slew of sensors, and much more. The latest flagship comes with a rear side heart rate sensor, as well as a fingerprint scanner embedded into its Home button. The design is only slightly changed, in that it now sports a sort of a "band aid" back cover design, but it's still made of plastic.

The original Galaxy Gear smartwatch from Samsung received more criticism than positive reviews, but the company has done its best to come up with a better iteration. The Galaxy Gear 2 is completely different compared to its predecessor, sporting a revamped design, a relocated camera, a thinner body, and interchangeable wristbands, among others.

The new Galaxy Gear 2 smartwatch also boasts notable changes inside, and has ditched Google's Android operating system in favor of Tizen OS. The gadget is built with a focus on health, featuring a heart rate sensor just like the Galaxy S5 it accompanies.

The Galaxy Gear Fit wristband, meanwhile, was designed specifically for health, as Samsung aimed to offer more than just a fitness band with a touchscreen display. Its functionality is more limited compared to that of a smartwatch, but it looks like a useful gadget nonetheless.
