Sony's lovely Xperia Z1S (pictures)

LAS VEGAS -- With a big, bright, 5-inch full HD LCD screen (1920x1080p), 2.2Ghz quad-core Snapdragon 800 processor, and T-Mobile 4G LTE, the Xperia Z1S melds both beauty and brains.

Measuring a svelte 0.34 inches thick by 5.74 inches tall by 2.91 inches wide, the Xperia Z1S is quite pocket-friendly.

Like its global sibling the Xperia Z1, and like other Xperia mobile device counterparts, the Xperia Z1S has a back surface crafted from glass. It's a handsome and premium look but is highly reflective and attracts fingerprints easily.

One slight difference between the Sony Xperia Z1S and the global Xperia Z1 is that T-Moble has moved the 3.5mm headphone jack to the center of the phone's top edge.

Sony places all the physical controls for the Xperia Z1S on its right side. Here you'll find a big circular power key, volume bar, and dedicated shutter button.

To help the Sony Xperia Z1S meet its IP58 durability rating, the phone's ports and expansion slots are sealed behind watertight flaps.

The Xperia Z1S comes running Android 4.3 Jelly Bean with Sony's proprietary skin layered over it.

The Xperia Z1S uses a main 20.7-megapixel camera for picture and video shooting duties. The camera also relies on the company's higher quality G Lens.

The camera app installed on the Xperia Z1S features many image processing bells and whistles.
