Cortex A15 articles
To compete with Samsung's flagship smartphone, Huawei apparently already have a handset to compete with it. According to rumours, Huawei is working on a direct Galaxy S IV competitor, which should have a 4.9-inch 1080p display and a quad-core ARM Cortex-A15 processor.
A Linux patch change-log (Android is a Linux-derivative) may have revealed that Samsung's next flagship smartphone, the Galaxy S IV, will be driven by its Exynos 5440 quad-core processor, based on the ARM Cortex-A15 micro-architecture. Samsung could flash it at CES '13.
