LG's wallet-friendly lineup of 'K' phones

If you're in the market for an affordable phone, LG has added four handsets to its series of midtier, K-series phones. And they're all here at CES 2017.

The K10 is the largest and most advanced of the series. It has a 5.3-inch display with a 1,280x720-pixel resolution.

On the back is a 13-megapixel camera and a fingerprint sensor. It runs Android Nougat and has expandable storage up to 2TB.

As the most "high-end" of the midrange series, the K10 has a few nodules of aesthetic flair, like copper accents here and there.

The 5-inch K8 (left) and K4 are the next down the line.

These device are pretty similar. They both have a 5-megapixel front-facing camera and a removable 2,500mAh battery.

However, the K8 (right) is slightly more advanced with the recent Android Nougat OS, a better 13-megapixel rear camera, a sharper screen and twice the amount of built-in storage at 16GB.

Another look at the K8 and its silver coloring.

The smallest of the family is the 4.5-inch K3. As such, it doesn't have the most powerful hardware and its build feels somewhat cheap and plastic.

The K3 has a four-core processor like the K8 and K4, but it has a smaller battery, a 5-megapixel camera and Android 6.0 Marshmallow.

Availability and pricing for any of the K-series phones haven't been announced yet, but expect the K10 (pictured here) to be the most expensive of the lineup, while the K3 is likely the cheapest.
