Does multitasking features, video calling, retina display, and HD video recording will be increasingly assertive treat Apple iPhone position as the king of smartphones. Apple iPhone which first appeared in the know n 2007 smartphone will change the existing order had recently. Call it innovation the multitouch screen iPhone later imitated by almost all manufacturers of smartphones. Apple's regular smartphone update every year, this time came with innovative observation in the year 2010. Besides having the village in both new and mate rials, Apple also to upgrade some hardware components are attached. Call it like a faster processor (Apple A4), 512 MB memory, HO video recording (720p, 30 FPS), camera 5 megapixel.
Still not sufficient, aspect of software is also upgraded to include the operating system (OS) new, namely IOS 4. The new OS offers the ability to multitasking, the management program in a folder, video calling (FaceTime), Voice Over screen technology for the use of blind people, Microsoft Exchange ready, the program Secure MobileMe, and keyboard support 34 language.
Retina display
Although some manufacturers smartphone still produce smartphone with a screen size of 4 inches (hexgonal), such as HTC and Motorola, Apple with iPhone 4 still able to compete only with the display 3.5 inch. According to the consideration of quality text, images and videos that appear on the screen much more determined by pixel factors. For that, Apple developing new pixel have only 78 micrometers (4x iPhone 3GS pixel number is the same areas). The result, 3.5-inch display iPhone 4 could have screen resolution to 960 x640 pixels.
By mathematical calculation, pixel density is 326 iPhone four pixels per inch. With this density, view text and graphics appear more refined and detailed. In addition, color reproduction is also seen more accurate. Retinal screen display iPhone 4 which IPS Technology(in-plane switching) like iPad that also given a scratch resistant glass coating. The Hight of brightness screen (800:1 contrast ratio) is obtained from the LED backlighting. There are also facilities intended ambient light sensor cents to iPhone four more power-efficient.
Solid framework of a weak signal
One of the four who are appointed special iPhone Stev e Jobs is material using the around of the iPhone, which is made from material that is claimed more strong if compare with stainless steel metal. In addition to strengthening the structural the iPhone, this framework enabled as well as an antenna for wireless connection (Bluetooth, WiFi, GPS, UMTS, GSM). Based on how some iPhone 4 users report, the framework has a dual function signal reception problems when the cell (in contact) with his finger on the bottom. Hypothesis for this problem, this is caused by effects metallic conduction with a finger. As solution, users can adjust the positioning of the handling or using a non konduktlf cover (casing). Until now, the problem is not serrious responsive by Apple.
Brightness :
Retina Display iPhone screen four more obvious than the iPhone 3Gs, thanks pixelnya density reaching 326 ppi.
Stretcher 100 new features :
Multitasking, folder management, e-mail services in a more perfected, iBooks facilities, spell checking, Tap-to-Focus Video, Custom background, 5x digital zoom, and tap-to-focus video represents some of the new features of iOS 4.
Dual sensor :
Collaboration acclerometer increase accuracy gyroscope and motion gestures and enjoyment user when playing games.
Problematic :
Antenna iPhone in complaining about some users because of signal interference in susceptible caused conduction effects.
