Samsung Galaxy S5 on February 24

The 'super curvy' smartphone is said to come in two versions and Samsung is speculated to swap the Amoled screen for an LCD.
According to Cnet, the device would include a 16 megapixel rear camera and a 2 megapixel front camera with Snapdragon
Earlier speculations pointed that the Galaxy S5 would not include either an ' iris scanner' or a ' quad-HD display ' and would rather include modest changes like a better camera, a better processor, and some alterations to its design, along with a new version of Samsung's Knox security software.
We have been hearing reports that claim Samsung's unPacked 5 event, which is expected to see the next Galaxy flagship smartphone launched, will be a low-key event. However, there's no shortage of speculation about what will be included in the Samsung Galaxy S5.
Now a new teaser image of the Samsung's much-anticipated Unpacked 5 event has been shared by the South Korean giant, which tips-off the new UI of the Galaxy S5. The teaser image shows the new colour theme and fonts of the new TouchWiz UI, which is not very similar to previous leaks that tipped the Samsung's new TouchWiz UI overhaul.
The teaser image also lists some features, namely: Speed, that might hint about the long-rumoured Snapdragon or Exynos chipset in the smartphone; Outdoor, which we assume is for the upgraded battery capacity in the Galaxy S5; Fun, Style and Social, which point to some new apps in the device; Privacy, points to the upgraded Knox security software expected to be preloaded on the Galaxy S5, and Fitness, which can be expected to point to new health related apps. Samsung Mobile's official Twitter handle said, "#UNPACKED in Barcelona. 24 February, 20:00 CET."
