Sony Xperia Z1SAt CES 2014, Sony announced that the Xperia Z1S will be available in US through T-Mobile starting January 22 and will be priced at $22 per month for two years or will be available at $603 outright (without contract). The Xperia Z1S has similar specifications as the Xperia Z1, though the former comes with a higher IP58 waterproof rating, which means the device, can be submerged into water for more time and depth.
The Sony Xperia Z1S comes with 5-inch full-HD Triluminos display powered by Sony Mobile BRAVIA Engine 2. It is powered by 2.2GHz quad-core Qualcomm MSM8974 processor along with 2GB of RAM. It runs Android 4.3 Jelly Bean out-of-the-box with Sony's custom skin on top, similar to the one seen on the Xperia Z1. The Z1S offers 20.7-megapixel Exmor RS sensor alongside BIONZ image processor engine and pulsed LED flash. It also includes a 2-megapixel front-facing camera. It packs in 3000mAh battery. Connectivity options on the Xperia Z1 include Wi-Fi, Bluetooth, NFC, Xperia Link and 3G.
