IN DEPTH: Samsung Galaxy S6 Edge vs LG G Flex 2

Smartphones have reached the point where designs are more iterative than innovative. While the look and feel changes only slightly on new models each year, manufacturers haven't done much to wow consumers beyond the traditional rectangular slab of glass, metal and plastic.

LG attempted to shake things up last year with first G Flex, a 6-inch smartphone with a curved display and slightly flexible frame, and Samsung soon followed with their own take on this concept, courtesy of the Galaxy Note Edge, a phablet-sized model featuring a display that wraps around the right side.

These Korean tech titans wasted no time announcing all-new versions of these devices for 2015, and we sat down with both in an effort to determine whether curved and flexible displays actually enhance the experience or are little more than a marketing gimmick.

Screen

Although it won't hit stores until April 10 (with preorders now available in 20 countries), the Samsung Galaxy S6 Edge is little more than a variant of this year's Samsung Galaxy S6, featuring nearly identical specs with one notable exception: The Edge's display gently wraps around both sides of the front.

Otherwise, the Galaxy S6 Edge offers the same 5.1-inch Quad HD Super AMOLED display as its less curvaceous sibling, with a resolution of 2560 x 1440 that packs in a whopping 577ppi.

The new LG G Flex 2 one-ups Samsung's latest with a 5.5-inch Full HD P-OLED display which curves slightly from top to bottom, and like its predecessor, can handle a bit of bending without breaking.

Despite the larger screen, the G Flex 2 tops out at a resolution of 1920 x 1080 with a pixel density of only 403ppi, but LG attempts to make up for this shortcoming by comparing the curved display to its high-end televisions, offering a more cinematic viewing experience in landscape mode with three modes (Standard, Vivid or Natural) to make any content look great.

Design

Weighing only 4.66 ounces (132 grams), Samsung's curved Galaxy S6 Edge offers a premium feel that's slightly less ergonomic along the edges, but the aluminum frame and 7mm thickness make the device feel lighter than the Galaxy S6.

Roughly the size of an iPhone 6, Samsung borrowed a somewhat annoying trait from Apple's latest flagship handset: The rear camera protrudes from the back ever so slightly, presumably a design compromise to keep the device slim and trim.

Instead of curving around the edges, LG's G Flex 2 bends the entire case inward vertically, and because of the larger display size, its contoured body weighs slightly more at 5.36 ounces (152 grams) with a 5.87 x 2.96 x 0.37-inch (149.1 x 75.3 x 9.4mm) frame.

Processor and Storage

Just because it looks so nice on the outside, that's no reason to be a slouch when it comes to what's on the inside.

The Samsung Galaxy S6 Edge obliges with an octa-core, 64-bit Exynos 7 Octa 7420 processor clocked at 2.1GHz capped off by a Mali-T760 MP8 GPU and a whopping 3GB RAM and up to 128GB of storage for good measure.

LG mostly made up for the lack of oomph on the first G Flex by slapping an octa-core, 64-bit Qualcomm Snapdragon 810 processor into the sequel, clocked at 2.0GHz with Adreno 430 GPU and the same 3GB RAM.

Unfortunately, the built-in storage on the G Flex 2 maxes out at 32GB, but up to a totally insane 2TB of additional storage is available from an optional microSD card – a feature sadly lacking on the otherwise hardware-rich Galaxy S6 Edge.

Battery

If you love the flexibility of swapping in a new battery when the current one runs out, neither of these curvy smartphones are likely to make you smile.

It's too early to know what the battery life will be like on the Samsung Galaxy S6 Edge, but the 2600mAh power pack doesn't offer a whole lot of encouragement on this front.

By comparison, the G Flex 2 packs a 3000mAh battery (reduced from 3500mAh in the previous model), but before LG can boast about having more power, there's the matter of that larger 5.5-inch display to consider.

Thankfully, the fast charging capabilities of both models should have you back in action quickly – our own review of the LG G Flex 2 topped up from a complete discharge in just over an hour and a half.

Cameras

Samsung hasn't held back when it comes to the Galaxy S6 Edge camera: Rocking a 16MP, f1.9 aperture sensor with dual LED flash and optical image stabilization capable of shooting 4K video up to 3840 x 2160, the rear camera is no slouch.

By comparison, the LG G Flex 2 borrows liberally from the LG G3 to provide a 13MP sensor that otherwise checks off the same feature list above on the Galaxy S6 Edge, although the laser auto focus is one noteworthy addition.

Neither model breaks much new ground with the front camera, however: Samsung touts a "best-in-class" 5MP sensor with 120º wide angle lens, while LG's tops out a 2.1MP, which the manufacturer claims is enough to use it as a "full HD camcorder."

Features

The remaining feature checklist is relatively the same for both handsets: Each ships with Android 5.0 Lollipop out of the gate, with the usual Bluetooth 4.1, NFC and 802.11 a/b/g/n/ac wireless on board.

Aside from curved edges, the Samsung Galaxy S6 Edge also offers built-in Qi and Powermat-compatible wireless charging.

LG instead opted to include a selfie-friendly "Gesture Shot" mode on the G Flex 2, which provides a three-second timer on the front-facing camera that can be activated with a gesture; tilting the camera down allows the user to review images instead.

Like the original G Flex, the sequel also features that bizarre self-healing back, which didn't do all that much to impress in our own review of the G Flex 2. More impressive is the Glance view, which offers a peek at what's happening without the need to actually turn on the device.

Galaxy Edge 6 vs G Flex 2 Verdict

This two-horse race ultimately comes down to just how curvy you want: Along the edges of the handset with the Samsung Galaxy S6 Edge, or on the entire smartphone with the LG G Flex 2.

LG has a slight advantage since the handset is already available from two carriers for early adopters to take home, but to be honest, the whole concept of curved displays on a smartphone still causes us to scratch our collective heads more than be impressed.

Samsung isn't likely to woo many potential Galaxy S6 buyers away from the flagship device in favor of the Galaxy S6 Edge either, but those in search of a more premium edition worthy of making friends envious will want to wait it out a bit longer – assuming you can afford it, that is.
