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 S3. It has new software features such as Smart Alerts, Smart Stay, and Smart Scroll, a 13-megapixel back camera, and a 4.99-inch (127 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.
