Sony Xperia Z1 Compact is a beautifully-crafted flagship smartphone of the popular Xperia Z series. It features a compact easy-to-hold body as compared to Sony's hot-selling phablet Xperia Z1 and comes with improved specs as well. The handset is expected to become available in the second half of February 2014.
The phone has a 4.3-inch TRILUMINOS HD 720p display and is designed for those who prefer to carry phones that allow quick one-handed operation. Its touchscreen boasts a resolution of 1280 x 720p and integrates Sony's X-Reality and BRAVIA Engine 2 technologies for sharp and brilliantly vivid color reproduction. The glass-aluminium constructed handset comes with a dustproof as well as waterproof body (IP55/IP58 rating). This essentially means that the Z1 Compact can withstand 30 minutes immersion in water at a depth of up to 1.5m.
Sony Xperia Z1 Compact runs on a speedy Quad-core 2.2GHz processor on Qualcomm's high-powered MSM8974 chipset. A powerful Adreno 330 GPU is also available on the chip for top notch graphics acceleration especially for Android gaming. The device provides 2GB built-in RAM and a 16GB internal ROM which comes with pre-installed Android OS v4.3 (Jelly Bean). In addition to its internal storage, the phone offers memory extension via a separately added microSD memory card.
The premium smartphone is equipped with an extraordinary 20.7MP rear camera. It features Sony's renowned G Lens and Exmor RS image sensor that captures crisp and clear photos by adjusting scene settings automatically. Since the smartphone itself is waterproof, you can take it underwater for some fun photography in the pool. The camera employs BIONZ image processing engine for blur-free results. Additional camera features include HDR, burst mode, 8x digital zoom, Full HD 1080p movie capture, image stabilization, subject tracking, 36 pre-programmed selectable scene types, built-in flash, touch focus/capture, face detection and 2MP HD front cam.
