Xperiablog got some information that Sony will soon announce and launch the Xperia ZR smartphone with a 720p display, a quad-core processor and a 13MP camera.
The Sony Xperia ZR will share lots of features with the Xperia Z flagship - a quad-core 1.5GHz processor (Snapdragon S4 Pro chipset), 2GB of RAM and a 13MP Exmor RS camera. Impressively, the Xperia ZR will be and even better protected, featuring IP58 rating for resistance under 1.5 meters of water for prolonged time. It will be dust proof too.
The Sony Xperia ZR 720p screen will reportedly measure 4.6" in diagonal, its internal memory will be 8GB, while the battery will have 2300mAh capacity. The Xperia ZR is rumored to be 10mm thick and to weigh 140 grams. Also we can expect the shell to be similar to the Xperia ZL one rather than the dual-glass Xperia Z body.
