Front-facing FaceTime HD camera
This 1.2-megapixel camera can shoot 1280 by 960 pixel stills and 720p HD video (1280 by 720 pixels), and has a backside illumination sensor for clearer low-light photography. The lens features a f/2.2 aperture, and the camera offers Auto HDR for both front-facing photos and videos, along with quick-shot burst mode. This camera is designed primarily for using FaceTime and snapping quick self-portraits.
With no headphones plugged in, this is where you place your ear to listen to incoming calls. Depending on your region, the iPhone may use wideband audio during telephone calls, which increases the vocal frequencies and provides better-sounding conversations.
Retina HD display
Both the iPhone 6 and 6 Plus sport a Multi-Touch Retina HD display; the device's touch sensors are integrated directly into the display, reducing sunlight glare and keeping the iPhone's figure slim. The iPhone 6's 1134-by-750-pixel Retina HD display packs 326 pixels per inch into the space allotted, while the iPhone 6 Plus offers a 1920-by-1080-pixel resolution at 401 pixels per inch. The display is made from optical-quality glass, which makes it highly scratch resistant. It also has an oil-resistant oleophobic coating that makes it easy to wipe off smudges.
Both the iPhone 6 and 6 Plus support Display Zoom, which enlarges apps and touch targets for easier visibility; in addition, double-tapping the Home button will enable Reachability, which slides down the top of the status bar to let you easily access screen elements in the top corners.
Home button/Touch ID sensor
The only physical button on the face of the iPhone, the Home button provides a variety of shortcuts for accessing apps and iOS features. Your Home button is also the location of the Touch ID sensor, which lets you use your fingerprint to unlock your device and bypass your iCloud password for purchasing apps and media; it also works as the primary authentication method for Apple Pay.
SINGLE-PRESS A single-press of the Home button can have several results, depending on what you're using the iPhone for at the time: If the phone is in sleep mode, pressing the Home button wakes the iPhone; if you're in an app, it returns you to the home screen; if you're on a subsequent home screen page, it returns you to the first page; and if you're on the first home screen page, it brings you into the iPhone's Spotlight search mode.
SINGLE-PRESS AND HOLD If you press and hold the Home button for at least two seconds, that activates Siri.
DOUBLE-PRESS When the phone is locked or in sleep mode, a double-press of the Home button wakes your device and brings up both the iPod controls and a shortcut for the Camera app. In active use, it brings up the multitasking bar, showcasing your active apps.
