Press the On/Off button to turn the iPad's screen on or off. You can still receive email and notifications with it turned off, but the screen stays blank until you wake it by pressing this button or the Home button. To turn the device off, hold the On/Off button down until the screen dims and the red "slide to power off" slider appears. Slide your finger across the switch, and the iPad mini powers down. (To turn your device back on, press and hold this button again until the Apple logo appears.)
You can also decline or silence alerts and alarms with the On/Off button; press it once to silence an incoming alert.
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). Apple designed the front-facing camera primarily for using FaceTime and snapping quick self-portraits.
The iPad and iPad mini don't have a tactile keyboard or many hardware buttons; instead, you use its LED-backlit Multi-Touch glass display to read books, surf the Web, compose email messages, navigate apps, and change settings. The screen 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.
The iPad's screen is 9.7 inches with a resolution of 2048 by 1536 pixels--at 246 pixels per inch, Apple describes it as a Retina display, meaning that the pixels are too small to distinguish with the human eye. If you have an iPad mini, you're looking at a 7.9-inch screen with a resolution of 1024 by 768 pixels (163 pixels per inch).
The only physical button on the face of the iPad and iPad mini, the Home button provides a variety of shortcuts for accessing apps and operating system features.
SINGLE-PRESS A single-press of the Home button can have several results, depending on what you're using the iPad mini for at the time: If the iPad is in sleep mode, pressing the Home button wakes it; 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 iPad's Spotlight search mode.
SINGLE-PRESS AND HOLD Press and hold the Home button for at least two seconds to activate Siri.
DOUBLE-PRESS When the device is locked or in sleep mode, a double-press of the Home button wakes your device and brings up the Music controls. In active use, it brings up the multitasking bar, showcasing your active apps.
