After posting a couple of introduction videos for the Galaxy S5 and the new Gear wearables a few days ago, Samsung has released on YouTube two new videos in which it offers its own hands-on preview of the new smartphone, smartwatches and fitness band. The new gadgets will be available in stores staring with April 11, although official prices are still not available. The two videos are significantly longer, revealing the specs of Samsung’s new devices as well as some of their features that were not thoroughly demoed on stage during the announcement event. Unlike with the Galaxy S4 launch, Samsung chose not to offer extensive demos of the new Galaxy S5’s software features during the MWC 2014 announcement event,
