The G3 is set to debut globally soon in the UK, US, and Australia. In the UK, the phone will be available on July 1 with a likely price of £490. In Australia, the 16GB version of the phone will go for AU$799, and in Singapore, the 16GB model will retail for S$868 (around AU$690, £410) without contract, while the 32GB will go for a slight markup of S$928 (AU$740, £440). We'll update this review when we have information about availability and prices in the US.

Design
Sporting the same rounded corners and slim bezel as the G2, the LG G3 keeps the same buttons on the rear as well. Instead of the glossy plastic found on the G2, though, LG has given the G3 a metallic-looking back.

LG says the rear cover is mostly plastic (to allow wireless charging to work), but it added a metal film to give it that shiny, polished look. The result is a very premium finish, and Samsung should pay attention here. While the dimpled rear cover of the S5 was a marked improvement over the glossy finish of the S4, the G3's back cover conveys a more luxurious feel that you normally get from metal phones such as theHTC One M8 or the Apple iPhone 5S.

Unlike the LG G Flex, though, its surface has no healing capabilities, so if you accidentally scratch the rear, you'll have to live with the battle scars.

As mentioned earlier, the power button and volume rocker are all found on the back. LG has done this for a few phones now, and while it takes some getting used to, it's actually a pretty good tweak. The keys have a textured pattern that differentiates them from the rear cover. It's also easy to reach the buttons when holding the phone with one hand. There's no need to stretch your fingers to power off the device (especially if it's on the top).

The 13-megapixel camera is located right above the rear buttons, and on the left is the Laser Auto Focus feature, which uses an infrared laser beam to measure the distance between the camera and the intended subject of your picture. On the right is the dual-LED flash.

The best part of the G3, however, has to be that there simply aren't any buttons. Unlike the S5, which has a physical home button, the G3 uses onscreen keys instead. This means that the 5.5-inch, 2,560x1,440-pixel-resolution screen grabs all of your attention, and the superthin bezel enhances that experience, making the phone appear to be "all screen."

The G3's display has an eye-popping 538 pixels per inch (ppi), while the iPhone 5S stops at 326ppi. That's 65 percent more pixels than Apple's handset, by the way. But does this really matter? In short, no. You'd be hard-pressed to tell the difference between a normal full-HD display and the QHD of the G3. The only time you could really see the difference would be if you were to put a drop of water on the screen and take a close-up shot. I did that with the Oppo Find 7, which has a 5.5-inch 2,560x1,440-pixel resolution display, and compared it with an Oppo Find 7a, which is a Find 7 with a 1080p screen. Thus, the difference in this shot is similar to what you'd see between an LG G3 and a regular full-HD phone -- barely perceptible to the naked eye.

But as CNET editor Andrew Hoyle found in his in-depth look at the G3's display, the G3's QHD screen has more natural color tones than the S5's screen (which has a warmer color cast). In the end, though, having a 1440p display is more about bragging rights for marketing than any actual visual improvement.

Located above the display is a 2.1-megapixel camera for taking selfies. (LG has also included a few features to make that process easier, but more on that later in the review.) LG has borrowed a page from Apple's book of tricks: the 3.5mm audio jack is located at the bottom of the phone, next to the Micro-USB jack.

Overall, I found the build quality to be pretty solid; the phone is easy to grip. The 8.9-millimeter-thin phone sits comfortably in the palm, but because of the width of its 5.5-inch display, it's often easier to to type with both hands.

The G3 comes with a redesigned Android 4.4 user interface (UI) that's very clean and flat. This new look is very familiar -- I've seen similar UIs from Asus and HTC, but that's not to say that LG's efforts are copies. According to LG, the G3's UI has been tweaked to keep things simple; instead of adding more features with each iteration, LG has decided to pare it down somewhat.

For example, instead of having 16 camera modes, LG checked its data and got rid of the modes that were used less than 1 percent of the time, leaving just four of the more frequently selected ones.
