Samsung is set to overhaul its TouchWiz user interface for the Galaxy S6 and S6 Edge to provide a more streamlined experience that’ll be snappier than ever before — but exactly how far will it go?

Will the South Korean company really do away with all of its own apps and make them optional? Apparently so. Sources say just three Samsung apps will come pre-installed on its next-generation Galaxy S devices.

For the Galaxy S6 and S6 Edge, Samsung is ditching all of its tacky plastic in favor of an all-new design made entirely from premium materials — and already its efforts are paying off.

According to carrier partners that have been given a sneak peek at the next-generation devices ahead of their official debuts on March 1, the Galaxy S6 beats the iPhone 6 in terms of design.

T-Mobile jumps the gun.

T-Mobile could be in trouble with Samsung today after it accidentally leaked the device that Samsung was trying so hard to keep under wraps. A pre-registration page on the carrier’s website reveals what appears to be the Galaxy S6 Edge in its first official shot so far.

Many of Samsung’s Galaxy smartphones support wireless charging, but only if you are prepared to buy an optional wireless charging back panel. But the South Korean company has vowed to accelerate the technology’s growth in 2015 with greater support in its new Galaxy smartphones.

In a new blog post, Samsung hints at the possibility of support for multiple wireless charging technologies inside the upcoming Galaxy S6.
