The first black and white photos of the much anticipated Samsung Galaxy S6, leaked schematics and supposed specs show a longer phone with improved innards that's more expensive than the iPhone 6.

Developed under the name, Project Zero, the S6 will finally be revealed at the Mobile World Congress 2015 that will take place from March 2 to 5 in Barcelona, Spain. But until that time, Samsung enthusiasts will have to be content with leaked specs and photos of the device.

The consensus among Samsung watchers is the S6 will be the most extensive update to Samsung's flagship line. Unproven are rumors the S6 will be the first phone with a curved screen and the first with a casing made from graphene.

Display: The consensus is the S6 will have a display size of slightly over 5 inches. Bets favor a size of 5.2 inches or 5.3 inches compared to the 5.1 inches of the S5, according to Trusted Reviews. The bezels of the S6 are expected to be more streamlined.

However, Samsung will actually trim the display size to just 5 inches, Slash Gear believes. The S6's display could be a QHD display, which will be an improvement over the S5's 1080p Full HD.

For the material of the S6, Samsung will move away from its plastic form factor into a premium, metal design similar to that of the new Samsung Galaxy Alpha. Leaked photos seem to confirm a metal build but the exact type of metal is uncertain. The use of graphene for the S6 body has been mentioned but pundits believe the use of this new material will be set aside for later phones.

The operating system of the S6 will stick with Android since Samsung's Tizen OS remains unready for prime time. The processor could be Qualcomm's new Snapdragon 808 and Snapdragon 810 CPUs unveiled in April 2014. These are confirmed reports these were to have been installed in their first handsets in early 2015. The S6 is the only phone set for release in early 2015.

It is widely believe the 32 GB S6 could sell for $850. The 64 GB version could come in at $970 while the 128 GB version could cost $1,000.
