Last week, Samsung finally unveiled the two latest phablets in its premium lineup at the Samsung Unpacked 2015 event. As per usual, Samsung showed off a new iteration of the Galaxy Note line, the 2015 Galaxy Note 5. But the company also announced a highly anticipated phablet version of the Samsung Galaxy S6 Edge: Simply known as the Galaxy S6 Edge+ (Plus).

Here's what you need to know.

Meet the Samsung Galaxy S6 Edge+

On first acquaintance, this phone will seem familiar. That's because the Galaxy S6 Edge+ is essentially an overgrown, over-powered Samsung Galaxy S6 Edge.

It shares all the same essential design elements that the Galaxy S6 Edge debuted, including metal and glass premium build materials.

Most importantly, it sports the same dual curved-edge display design, just bigger and with a few extra features -- and of course, Android 5.1 Lollipop.

Hardware Specs: Similarities and Differences

The Galaxy S6 Edge+ carries the "Plus" notation mostly for the 0.4 inches more screen real estate that you'll get with this oversized phone.

The original Galaxy S6 Edge had a 5.1-inch Super AMOLED display, with Samsung's signature cascading curved glass display rounding out both sides of the phone.

The Galaxy S6 Edge+ ups the screen space to 5.7-inches and keeps the curved Edges. However, Samsung managed to increase the size of the screen without blowing up the size of the phone itself too much. In fact, the Galaxy S6 Edge+ is only 5mm wider, 12mm taller, and actually just barely thinner than the Galaxy S6 Edge.

The phablet's display resolution is still quad HD, but it will yield a lower pixel density compared to its diminutive cousin (which sported a ridiculous 577 pixels per inch using quad HD on a 5.1-inch screen).

The power sipping octa-core Samsung Exynos 7420 system on a chip remains unchanged from one phone to the next, even in its two quad-core processors' respective clock speeds of 1.5 GHz and 2.1 GHz.

But this phablet comes with 4GB of RAM instead of three on the original, and Samsung upped the battery (albeit only slightly) to 3000 mAh, with the same fast-charging and wireless charging features of the Galaxy S6 Edge. However, with the same premium build, there's unfortunately still no removable battery, and no storage expansion available through microSD.

Welcome Tweaks

Both devices pack a 16-megapixel main camera, with a 5-megapixel front-facing sensor for self-shots.

But the Galaxy S6 Edge+ introduces new camera feature in Samsung's default photography software: The ability to stream live 1080p video at 60 frames per second, straight to YouTube at the push of a button.

Another tweak present in the Edge+ that evolved out of the Galaxy S6 Edge will give you more use from those curved edges.

As the Galaxy S6 Edge had a software widget for the curved screen called "People Edge" -- which gave you a handful of shortcuts to contacts and notifications -- a new widget in the phablet version called "Apps Edge" gives you shortcuts to apps in the same space. This will likely make one-handed operation much more convenient on the larger screen.

Release Date & Price 

The Samsung Galaxy S6 Edge+ is definitely a phablet, and it's definitely a premium smartphone, meaning it will cost more than your average device.

In fact, expect the Galaxy S6 Edge+ to generally cost about $100 more than a comparable storage model of the Galaxy S6 Edge -- like $300 with a two-year contract on a 32GB device, rather than $200. The 64GB version gets even more expensive, averaging $400 with a two-year contract, or over $900 unlocked.

You may have trouble rounding up the cash for the Samsung Galaxy S6 Edge Plus, but come August 21, you won't have a problem finding one for sale.

August 21 is the U.S. release date for the Samsung Galaxy S6 Edge+, and it'll be available on Verizon, Sprint, AT&T, T-Mobile, U.S. Cellular, online from Samsung or at Best Buy, all on Friday.
