The iPhone 3GS is powered by the Samsung APL0298C05 chip, which was designed and manufactured by Samsung. The iPhone 3GS's camera app features a slider which allows users to switch between capturing photos and recording videos, a tap-to-focus feature which allows users to tap on an area of the camera image to auto-focus on, 5x digital zoom (iOS 4 or later), autofocus and auto exposure lock when holding an area down (iOS 5 or later), and gridlines for composition (iOS 5 or later). In addition to the higher pixel count, it also features auto-focus, auto white balance and auto macro and is capable of capturing VGA video.
The iPhone 3GS features an improved 3- megapixel camera manufactured by OmniVision. The capacitive touchscreen is designed for a bare finger, or multiple fingers for multi-touch sensing.
Improvements over its predecessor's screen include 24-bit color emulation (18-bit color display plus dithering) for a more color rich display and oleophobic coating to help reduce fingerprints on the display.
It features a capacitive touchscreen with a pixel density of 163 pixels per inch (ppi) on a 3.5 in (8.9 cm) 480-by-320 display. The LCD display on the device was designed by Apple and made by LG. Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it vertically (one common result is switching from portrait to landscape mode). Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch, all of which have specific definitions within the context of the iOS operating system and its multi-touch interface. Interface control elements consist of sliders, switches, and buttons. The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. The iPhone 3GS features iOS, Apple's mobile operating system. Main articles: iOS, iPhone OS 3, iOS 4, iOS 5, and iOS 6
Though in addition to the upgrades mainly regarding performance, various software features were also introduced exclusively to the iPhone 3GS such as video recording, voice control, and digital compass.

After the release of the iPhone 4S, the 3GS was still offered for free on a contract until November 2011, when AT&T raised the price to 59 cents with no explanation. It reached its first million units sold as quickly as its predecessor, the iPhone 3G. Within the first weekend of its release, over 1 million iPhone 3GS units were sold.
