In just a few hours Samsung will take the stage at its March 1 Galaxy S6 event at Mobile World Congress. It will launch the Galaxy S6 and Galaxy S6 Edge, and we now have a better idea of the curved display S6 Edge's design from leaked renders.

HTC and Samsung will kick off Mobile World Congress 2015 with events on March 1. The smartphone manufacturers will both present their latest and greatest flagship devices for the year. We've been covering HTC and Samsung in particular leading up to March 1, since the Galaxy S6, S6 Edge, HTC One M9 and One M9 Plus are sure to be among the most popular Android smartphones released in 2015.

We reported back in January that images of the HTC One M9 and One M9 Plus leaked online, giving the world a view of HTC's unannounced smartphone and phablet. Benchmark scores for the One M9 and One M9 Plus also made their way to an online benchmarking site where the complete specs of both devices appeared, along with impressive scores. HTC faced its biggest leak when official HTC One M9 videos hit the web.

Samsung was unable to prevent a rash of Galaxy S6 and S6 Edge leaks over the last few weeks. A video compared a Galaxy S6 mockup based off of the smartphone's schematics and compared with Apple's iPhone 6. We got our first look at what is reportedly an AT&T Samsung Galaxy S6, which confirmed Samsung's new design approach of using premium materials like glass and metal. Samsung's other model, the curved display Galaxy S6 Edge, has appeared on benchmarking sites and we got a glimpse of its unique design thanks to T-Mobile and AT&T.

If you want to get an even better look at the dual-sided curved display Galaxy S6 Edge, Nowhereelse has posted renders of the smartphone, showing off its sleek, metal build and unique display that wraps around both sides of the Samsung Galaxy S6 Edge. The rumored, redesigned Home button is larger than previous smartphones but is believed to house a more improved and iPhone-like Touch ID scanner. Like the iPhone 6 and iPhone 6 Plus, it appears that Samsung has been forced to use a protruding camera on its rear due to the thinness of the smartphone.

We'll be covering Mobile World Congress 2015 and will bring you all the latest news from the event. Stay tuned.
