Samsung on Sunday announced two new additions to its Galaxy family of mobile devices, the Samsung Galaxy S7 and Galaxy S7 edge.

The Samsung Galaxy S7 features a 5.1-inch Quad HD Super AMOLED display (2,560 x 1,440 / 577 PPI) with an always-on feature that's powered by a quad-core SoC (two cores operating at 2.15GHz and two operating at 1.6GHz) alongside 4GB of RAM. FYI, international markets will get an octa-core chip (four cores operating at 2.3GHz and four cores clocked at 1.6GHz).

Both chips are built on a 14-nanometer manufacturing process, Samsung said, and utilize an internal heatpipe cooling system to ensure overheating won't be an issue.

The Galaxy S7 edge, meanwhile, packs a larger 5.5-inch Quad HD Super AMOLED Edge display (2,560 x 1,440 / 534 PPI) that's powered by the same SoC and 4GB of RAM. Both handsets come with a 12-megapixel Dual Pixel rear-facing camera with f/1.7 aperture lens and optical image stabilization as well as a 5-megapixel selfie camera, also with an f/1.7 aperture lens for improved performance in low light situations.

Samsung says the CPU in its new smartphones is 30 percent faster than what's found in the Galaxy S6 and the GPU is about 60 percent faster.

The two smartphones will be offered in your choice of 32GB or 64GB of local storage that's expandable via microSD card slot unlike its predecessors. Both phones feature LTE Category 9, wireless charging that's compatible with WPC and PMA, NFC, MST, 802.11 a/b/g/n/ac dual-band Wi-Fi, MIMO, Bluetooth 4.2 LE, ANT+, USB 2.0 and a variety of embedded sensors.

They also come IP68 rated for liquid and dust resistance meaning the devices can be submerged in a meter and a half of water for up to 30 minutes without incurring damage.

The smaller Galaxy S7 packs a 3,000mAh battery while the larger edge is powered by a 3,600mAh. Neither is removable but it's still an improvement over the devices they replace without a change in their footprint.

Both handsets will ship with Android 6.0 Marshmallow as we saw them in action on the demo floor already running the OS smoothly with the usual Samsung skin.

The Galaxy S7 and S7 edge will be available starting mid-March. Pricing hasn't yet been announced although the company did say that anyone who orders a new Galaxy phone will receive a Gear VR as a free gift. AT&T will begin accepting pre-orders for both phones on February 23 with devices landing in stores March 11.
