Sony on Monday announced its new smartphone flagship in the form of Xperia Z4. The phone sports an aluminum frame and is thinner than its predecessor at 6.9mm. According to Sony, it will go on sale later this summer, beginning with Japan.

There isn’t much change in the Z4 from the company’s last flagship Xperia Z3. Sony Xperia Z4 sports a 5.2-inch full HD display and is powered by 2.0GHz octa-core Qualcomm Snapdragon 810 processor. It runs on Android 5.0 and packs 3GB of RAM, 32GB of internal storage and microSD card slot.

The phone is also water and dust proof like its predecessor and comes with NFC support, 4G LTE, and 2930 mAh battery. On the imaging front, the company has included a 20.7MP rear camera and 5.1MP front shooter with a wide-angle lens in the Z4. In addition, the handset supports Sony’s LDAC audio technology, which allows high quality wireless audio streaming via Bluetooth. LDAC was not available in any smartphone until now.

There is no word on the pricing or exact availability details, but Sony has revealed that the new Xperia Z4 will be offered in four colour options – White, Black, Copper, and Aqua Green.
