Brand new iPhone, brand new Design
The first thing anyone will notice about the Apple iPhone 4 is how its design is vastly different from the previous iPhones. The front of the iPhone 4 still retains the ever compulsory single piece of glass (not just any normal glass, but aluminosilicate-toughened glass!) with the single Home button that is centred on the lower chin of the iPhone 4.
The very rounded rear of the previous iPhones is now totally gone, replaced by another sheet of the toughened glass to make for an incredible slim and sleek smartphone. The sides of the iPhone 4 are also now made of strong stainless steel, giving the phone a very industrial and classy finish, as well as more surface area for users to properly hold the smartphone. All in all, the iPhone 4 was an iPhone with a great combination of the form and function.
Superior viewing experience with Retina Display
The Apple iPhone 4’s physical design is not just the only big change. The iPhone 4 also has a Retina Display, one of Apple’s largest features in all of its devices. Apple’s term, Retina Display, refers to the pixel count in a display at a number that is high enough that our naked eye cannot discern individual pixels from one another, forming images that are exceptionally sharp to the eye.
The iPhone 4’s 3.5-inch display sports a resolution of 960 x 640 pixels, resulting in a 326 ppi (pixels per inch) on the display. In the real world usage, this means that every single thing shown on the smartphone’s display, be it text or images, appear crystal clear – most people would be hard pressed to be able to even see any pixilation on the iPhone 4’s Retina Display. It may be a small display, but it surely packs a lot of pixels in its punch.
The iPhone 4’s camera is also a rather capable camera. Sitting on the rear of the iPhone 4 is a 5-megapixel camera with LED flash. Where many competitors of the iPhone are opting for larger megapixels in their camera sensors, Apple stays adamant with its 5-megapixel camera sensor, offering superior images to most other smartphones.
The camera sensor in the iPhone 4 has enhancements in the form of backside illumination, which helps the camera perform better in lowlight environments, which works. Images taken in lowlight situations are sharper and have lesser noise compared to other smartphone cameras.
