This is what we mean by the G4 almost passing for a standard smartphone, as it's 6 percent shorter and 3 percent narrower than the iPhone 6 Plus – despite both having 5.5-in screens.
The G4 is 38 percent thicker, though that number is a little exaggerated, since the G4 has a rounded back (measuring only its thickest point) while the iPhone's thickness is uniform.
Thanks (mostly) to that smaller size, the G4 is also 10 percent lighter than the iPhone 6 Plus.
There are two versions of the G4: one with a leather back, another made of plastic.
Within each of those build categories, LG gives you two color options to choose from.
Both handsets have 5.5-in screens.
The G4 gives you a much sharper picture, with its Quad HD resolution.
Both phones have IPS display panels.
The iPhone uses Apple's excellent Touch ID fingerprint sensor, for securing your phone, logging into supported third-party apps and using Apple Pay.
Camera megapixels (rear)
The G4's rear camera has the higher resolution, but that won't necessarily make it a better camera. Stay tuned on this front.
Camera megapixels (front)
The difference in pixels here is huge, though, so it's probably a safe bet that you'll take better-looking selfies on the G4.
The G4's rear camera also has a wider aperture, which is often a good hint that it will fare well in low-lit conditions.
Both handsets also have Optical Image Stabilization for their rear cameras.
The G4 brings back one of our favorite features from the LG G3, its laser-based autofocus. It quickly and automatically measures the distance between camera and subject, and (almost immediately) takes a shot with that part in focus. On the user end, it's as simple as tapping the point on the screen where the subject is.
The G4 has the higher-capacity battery but, similar to camera resolution, we won't know if that means anything until we put it through the paces. Stay tuned.
The G4 does have the perk of letting you swap its battery on the go, a quality that's becoming increasingly rare in Android phones.
There's no internal storage decision for G4 buyers, as 32 GB is your only option.
The G4 does, however, have a microSD card slot.
The G4 triples the iPhone's RAM.
On paper, the iPhone's core count and clock speed looks dated by at least two or three generations. But that's a little deceiving, as Apple's mobile chips typically far outperform what you'd expect from their processor specs.
The G4 has yet to launch in the US (and we don't yet have a firm release date on that), but it's already available in South Korea.
The latest iPhones launched last September, so we could be about four months away from Apple's next batch.
Starting price (full retail)
We still don't know what the G4 will cost outside of Korea.
Starting price (on-contract)
That includes on-contract pricing as well.View gallery - 24 images
