Samsung's next-generation Galaxy S6 smartphones promise to bring a slew of new improvements to the table, including a much-waited for streamlining of the TouchWiz interface.

A new report from Business Korea reveals that Samsung is focused on slimming down TouchWiz by eliminating unnecessary features and boosting core ones. Samsung is expected to unveil the Galaxy S6 around the time of the Mobile World Congress in Barcelona in March.

"We are aiming to get rid of unnecessary functions and simplify our UI at the level of Google's Nexus 6," an industry source told Business Korea Jan. 12.

Google's Nexus 6 is part of Google's Nexus lineup that consists of devices that run the version of Android that comes straight from Google. This means that it isn't layered with interfaces like TouchWiz and thus usually operates faster and smoother.

TouchWiz, which has been a staple in the Galaxy S and Galaxy Note series for years now, is Samsung's front-end user interface. Although the interface contains several features that are unique to Samsung's offerings, users have repeatedly complained about the interface's sluggishness. This is due to the fact that TouchWiz essentially runs on top of Android, eating up more memory in the process. One of the main complaints in recent years has been that Samsung's TouchWiz is full of unnecessary, gimmicky features -- an opinion consumers seem to echo as Samsung's sales of the Galaxy S series have slowed down.

Samsung has not released any details nor confirmed any concerning the Galaxy S6, so be sure to take in information at this point in time with a healthy dose of skepticism. Samsung is said to be designing the Galaxy S6 from the ground up so that it oozes a fresh perspective. As such, the company is said to be testing several models and several approaches, and the final product could end up resembling none of the prototypes currently floating about.

"As far as performance, benchmarks are noticeably higher but not by earth-shattering amounts. Overall device responsiveness is vastly improved, and memory consumption is way down," wrote a Samsung employee on Reddit. "Some builds have freed over a gig of memory consumption from cold boot... not just specs Samsung is focusing on this time around. I've heard lots of rumblings about crazy new designs (and I'm not just talking Galaxy Alpha 'redesigns' either.) Spec-wise though, that all lines up with what I've seen/heard, but again there's quite a good chunk of time between now and April."

Rumored specs so far include a 5.5-inch Super AMOLED QHD display, a 64-bit Qualcomm Snapdragon 810 or eight-core Exynos 7 Octa processor, and either a 16-or-20-megapixel rear-facing camera.
