LG: A few important bits:

  • Display: 5.5-inch Quantum IPS LCD (slightly curved)
  • Pixel Format: Quad HD (QHD) 2560×1440 RGB Stripe
  • Resolution: ~538 ppi
  • Cover Glass: Corning Gorilla Glass 4

Quantum IPS sounds mighty impressive, and it is. Compared to the G3:

  • Brightness: +25%
  • Contrast: +50%
  • Color Accuracy: +20%
  • Power Efficiency: +11%

And the slight curvature reduces the likelihood of breaking on impact by 20% compared to the G3.

The camera is vastly improved too:

  • Image Sensor: 1/2.6 inch, 16 megapixels
  • Lens: f/1.8
  • Image Stabilization: Yes, Optical
  • Autofocus: Phase Detection / Laser

The G4 sports a color spectrum sensor that improves color accuracy and white balance.

The iPhone 6 image sensor size is 1/3.0 inch; the G4’s is larger: 1/2.6 inch. The iPhone 6 lens aperture is f/2.2; the G4’s is significantly brighter at f/1.8. The LG G4 solely based on these specs looks like it will easily best the iPhone 6 & 6 Plus.

When it comes to the display there is little doubt the 5.5-inch 2560×1440 Quantum IPS LCD in the LG G4 is significantly better.
