The 5.2-inch, 1,920x1,080-pixel IPS display is sufficient, and twin stereo speakers make for some decent Netflix viewing. I can't say it's got the best call quality, though.

It's a little slow to focus, and crummy at low-light shooting, even if daylight images are perfectly okay. Here's a closer look at that camera module -- an f/2 aperture for a 13-megapixel sensor.
