The G4 is LG's newest flagship phone, the follow-up to the G3. Intriguingly, it comes in leather.
The back panels are removable: this optional one is covered in vegetable-dyed stitched leather, and feels pretty good...but underneath, the G4 is plastic.
The back of the G4 still has the power button and volume buttons on it like last year's G3, centered near the camera lens.
A 5.5-inch IPS Quantum Display has a quad-HD resolution: 2,560x1,440 pixel at 534 pixels per inch. It boasts improved brightness, contrast and color accuracy over last year.
The rear camera's been boosted to 16 megapixels, with an improved f/1.8 aperture for lower light photography, a larger sensor, and better optical image stabilization.

New camera modes include full manual control, with full access to adjusting ISO, white balance and other settings. Photos can now be shot in raw and JPEG format, too.
The slightly curved display isn't as pronounced as the Flex, but feels good to hold.
There are three different styles of back designs: a metal G3-like finish seen here, a ceramic painted back, and the leather back.
The G4 is slightly wider than last year's G3, but feels comfortable and not too large.

The LG G4 runs on Android Lollipop without too much extra -- LG intends it to be a streamlined, clean version of Google's software. Chrome is now the pre-installed browser of choice.

The rear panel can pop off, because the 3,000 mAh battery is replaceable. There's a microSD card slot, too, to expand the onboard 32GB of storage further.
