Introduction of iPhone

iPhone is a line of smartphones designed and marketed by Apple Inc. It runs Apple's iOS mobile operating system. The first generation iPhone was released on June 29, 2007; the most recent iPhones, the seventh-generation iPhone 5C and iPhone 5S, were introduced on September 10, 2013.

The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to many cellular networks, including 1xRTT (represented by a 1x on the status bar) and GPRS (shown as GPRS on the status bar), EDGE (shown as a capital E on the status bar), UMTS and EV-DO (shown as 3G), a faster version of UMTS and 4G (shown as a 4G symbol on the status bar), and LTE (shown as LTE on the status bar). An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send texts, GPS navigation, record notes, do mathematical calculations, and receive visual voicemail. Other functions — video games, reference works, social networking, etc. — can be enabled by downloading application programs ('apps'); as of October 2013, the App Store offered more than one million apps by Apple and third parties.

There are seven generations of iPhone models, each accompanied by one of the six major releases of iOS. The original 1st-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a faster processor and a higher-resolution camera that could record video at 480p. The iPhone 4 featured a higher-resolution 960×640 "Retina Display", a VGA front-facing camera for video calling and other apps, and a 5-megapixel rear-facing camera with 720p video capture. The iPhone 4S upgrades to an 8-megapixel camera with 1080p video recording, a dual-core A5 processor, and a natural language voice control system called Siri. iPhone 5 features the dual-core A6 processor, increases the size of the Retina display to 4 inches, introduces LTE support and replaces the 30-pin connector with an all-digital Lightning connector. The iPhone 5S features the dual-core 64-bit A7 processor, an updated camera with a larger aperture and dual-LED flash, and the Touch ID fingerprint scanner, integrated into the home button. iPhone 5C features the same A6 chip as the iPhone 5, along with a new backside-illuminated FaceTime camera and a new casing made of polycarbonate. As of 2013, the iPhone 3GS had the longest production run, 1181 days; followed by the iPhone 4, produced for 1174 days.

The resounding sales of the iPhone have been credited with reshaping the smartphone industry and helping make Apple one of the world's most valuable publicly traded companies in 2011–12. The iPhone is the top-selling phone of any kind in some countries, including the United and Japan. In the last quarter of 2013, there were 51 million iPhones sold, a new record, compared to 47.8 million in the last quarter of 2012. In March 2014, sales of the iPhone brand had reached 500 million devices.

iPhone-Related Video Issues

Video Format Not Accepted: Obviously, not all video formats are supported by iPhone, iPhone 5s included. Generally speaking, iPhone only natively supports MP4 (H.264/AAC), MOV (QuickTime) and M4V (H.264/AAC) video formats, so if you want to play unaccepted formats on iPhone, you'll need to convert them to the MP4/MOV, etc in advance.

Video Filmed Sideways: iPhone can be a great camera for capturing videos, however, with the rise of iPhone-captured videos, you probably have come across a few videos that were filmed sideways, right? This can make viewing difficult, to say the least. In this case, you have to rotate the video via 3rd-party apps.

Storage Used Up: If you love recording videos with your iPhone, you may have the problem that your device's storage is used up easily since iPhone HD videos are usually very large in size. Therefore, if you want to reduce the file size and release storage for your iPhone, you need to compress the videos in a proper way.
