Samsung Galaxy S IV +
The Samsung Galaxy S4 is a smartphone manufactured by Samsung Electronics. It was announced in New York on March 14, 2013. It is the successor to the Samsung Galaxy S III. It has new software features such as Smart Alerts, Smart Stay, and Smart scroll, a 13-megapixel back camera, and a 5-inch (130 millimetres) 1080p display. The international version features an Exynos 5 Octa ( octa-core ) chip containing the first big.LITTLE architecture central processing unit (CPU). The CPU, with four active cores and four inactive cores, emulates a quad-core CPU. It comprises one faster quad-core cluster, and one slower quad-core cluster. Only one cluster is active at any time, with the faster cluster selected on-demand to save power. It will be available in late April 2013 on 327 networks worldwide and in 155 countries and on or before May 1 on the US networks T-Mobile and AT&T.
