Pixel 2 XL vs LG V30: Cameras
A hugely important factor for any buyer is the camera experience. This one is really a toss-up, and something you'll need to decide for yourself. We'll only help you understand what's different.
LG is using two cameras on the V30. A main 16MP sensor that's extremely fast, and a second 13MP lens for wide-angle photos. The front is average, at 5MP. We know LG phones take pretty good photos, but they can't quite compete with Samsung or Apple, and now Google. If you need a super fast camera or a wide-angle lens, consider the V30.
However, Google's new Pixel 2 XL scored off the charts in camera tests. It received the highest DxOMark score in history. While it's only 12.2 Megapixels, Google is using computational photography and machine learning to improve the outcome from each and every photo.
Then, the second lens on most phones is for portrait mode and bokeh features. LG doesn't offer that, while Google does with just a single camera. Both cameras have optical image stabilization and lots of features, but we're pretty confident in saying the best camera experience is the Pixel 2 XL.
From what we're hearing, the Pixel 2 XL will have an unbeatable camera, at least until sometime in 2018. The only real benefit for the V30 is wide-angle photos, which is a niche feature.
