iphone 5

              The iPhone 5 is a touchscreen-based smartphone developed by Apple Inc.. It is the sixth generation of the iPhone and succeeds the iPhone 4S. The phone is a slimmer, lighter model that introduces a higher-resolution, 4-inch screen to the series with 16:9 widescreen aspect ratio. The phone also includes a custom-designed ARMv7 processor called the Apple A6, an update to Apple's mobile operating system known as iOS 6, and support for LTE.

            Apple held an event to formally introduce the phone on September 12, 2012. Apple began taking pre-orders on September 14, 2012 and over two million were received within 24 hours. Initial demand for the iPhone 5 exceeded the supply available at launch on September 21, 2012, and has been described by Apple as "extraordinary", with pre-orders having sold twenty times faster than its predecessors. After the launch of the device, Samsung filed a lawsuit against Apple, claiming that the iPhone 5 infringes eight of its patents.

While reception to the iPhone 5 has been generally positive, the new Maps application featured on iOS 6 was negatively received and was reported to contain many serious errors. Consumers and reviewers have noted hardware issues, such as an unintended purple hue in photos taken by the iPhone 5, consumer reports of the coating chipping off, and the presence of light leaks on white variants of the device. Incompatibilities with LTE networks in some regions have been noted.

Operating system and software:

           The iPhone 5 features iOS, Apple's mobile operating system. The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons. 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. 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).

 

             The iPhone 5 is shipped with iOS 6, which was released on September 19, 2012. Many of the iPhone 5's features that work specifically with the included iOS 6.0 operating system only worked in certain territories on release. Apple has said this is a rolling program, which will take longer to implement across more regions.

             The phone can act as a hotspot, sharing its internet connection over WiFi, Bluetooth, or USB, and also accesses the App Store, an online application distribution platform for iOS developed and maintained by Apple. The service allows users to browse and download applications from the iTunes Store that were developed with Xcode and the iOS SDK and were published through Apple.

             The iPhone 5 can play music, movies, television shows, ebooks, audiobooks, and podcasts and can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Options are always presented alphabetically, except in playlists, which retain their order from iTunes. Users can rotate their device horizontally to landscape mode to access Cover Flow. Like on iTunes, this feature shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen. Alternatively, headset controls can be used to pause, play, skip, and repeat tracks. On the 5, the volume can be changed with the included Apple Earphones, and the Voice Control feature can be used to identify a track, play songs in a playlist or by a specific artist, or create a Genius playlist.

Like the iPhone 4S, the iPhone 5 has Siri that allows the user to operate the iPhone by spoken commands. The software was improved in iOS 6 to include the ability to make restaurant reservations, launch apps, dictate Facebook or Twitter updates, retrieve movie reviews and detailed sports statistics.

                   On the iPhone 5, texting can be aided by the voice assistant, which converts speech to text. In addition to regular texting, messaging on the iPhone 5 supports iMessage, a specialized instant messaging program and service that allows unlimited texting to other Apple devices running iOS 5 or later. This supports the inclusion of content such as images and sound in text messages, integration with the device's voice-controlled software assistant, and read acknowledgements for sent messages. Input to the device comes from a keyboard displayed on the multi-touch screen or by voice-to text by speaking into the microphone. Entered text is supported by predictive and suggestion software; there is a multi-language spell-checker which recognises many regional accents of different languages.

iOS 6 features several new and/or updated apps, which includes Apple Maps and Passbook. Apple's built-in Maps app, which replaced the former Maps app powered by Google Maps, has been universally derided and lacks many features present in competing maps apps. It is also known to give inaccurate directions. It uses Apple's new vector-based engine that eliminates lag, making for smoother zooming. New to Maps is turn-by-turn navigation spoken directions, 3D views in some major cities and real-time traffic. iOS 6 is able to retrieve documents such as boarding passes, admission tickets, coupons and loyalty cards through its new Passbook app. An iOS device with Passbook can be scanned under a reader to process a mobile payment at locations that have compatible hardware. The app has context-aware features such as notifications for relevant coupons when in the immediate vicinity of a given store.

                 Facebook comes integrated through Apple's native apps with iOS 6. Facebook features can be directly accessed from within native apps such as Calendar which can sync Facebook events, or use Facebook's like button from within the Apple App Store.

New privacy settings are available to the user. In addition to location services, the following have been added in iOS 6: photos (already partially restricted in iOS 5), contacts (address book), calendars, reminders, bluetooth sharing, Twitter, Facebook, and Sina Weibo. iOS 6 also comes with a "Limit ad tracking" user control in the general settings menu to allow users the option to prevent targeted advertising. Apple's Advertising Identifier replaces the company's existing Unique Device Identification (UDID) standard. Advertising networks not yet using Apple's Advertising Identifier device identifier standard would not be affected, although Apple will require the standard in the future.
