Apple Inc. (NASDAQ:AAPL) has finally announce the release of the iPhone 6S, with the smartphone expected to hit the stores on September 25. The Apple handset will be going up against the Galaxy S6, the flagship offering from Samsung Electronics Co., Ltd. (LON:BC94) and Apple's most obvious rival in the marketplace.

Display Samsung has particularly specialized in producing high-quality displays in recent years, especially since it became the world's largest seller of television sets back in 2008. So we could naturally expect the Galaxy S6 to excel in this department, but the gap between the premium Samsung smartphone and the iPhone 6s should be considered something of a concern for apple. It was widely expected that Apple would improve the screen quality in the iPhone 6s. But the consumer electronics giant has confirmed that the iPhone 6s will retain the display resolution from the last generation iPhone 6.
