Mobile Phone Accessories
Mobile accessories include any hardware that is not integral to the operation of a mobile smartphone as designed by the manufacturer, and adds utility to the mobile phone. Cases Cases, which are designed to attach to, support, or otherwise hold a smartphone, are popular accessories. Case measures are based on the display inches (e.g. 5 inch display). There are different types: * Pouches and sleeves * Holsters * Shells * Skins * Fitted cases * Bumpers * Flip cases and wallets * Screen protection films * Camera protection films * Drop and shock protection * Leather cases * Cases with integrated kick stands * Battery cases * Cases with protection devices Holsters are commonly used as third-party cases for devices, and/or are made of plastic and without exposed rigid corners. Heavy duty cases are designed to protect from drops and scratches. A standing (or kickstand) case keeps the device standing upright. The collapsible kickstand of some horizontal cases holds the device i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   [Amazon] |

Screen Protector
A screen protector is an additional sheet of material—commonly polyurethane or laminated glass—that can be attached to the screen of an electronic device and protect it against physical damage. History The first screen protector was designed and patented by Herbert Schlegel in 1968 for use on television screens. In 1990s, the CRT screen protectors were used on CRT computer monitor, monitors for anti-glare and anti-radiation purposes. Later, they were adapted for use on LCD monitors. Screen protectors first entered the Mobile device, mobile-device market after the rise of personal digital assistants (PDAs). Since PDAs were often operated via a Stylus (computing), stylus, the tip of the stylus could scratch the sensitive LCD screen surface. Therefore, screen protectors provided sacrificial protection from this damage. Since then, the ubiquity of mobile device, mobile-devices have seen the screen protector become more widely used. Materials Screen protectors are made o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   [Amazon] |

Bluetooth Low Energy
Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries. Compared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. It is independent of classic Bluetooth and has no compatibility, but Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and LE can coexist. The original specification was developed by Nokia in 2006 under the name Wibree, which was integrated into Bluetooth 4.0 in December 2009 as Bluetooth Low Energy. Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as macOS, Linux, Windows 8, Windows 10 and Windows 11, natively support Bluetooth Low Energy. ...

Optical Zoom
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens (''prime lens''). A true zoom lens or optical zoom lens is a type of '' parfocal lens'', one that maintains focus when its focal length changes. Most consumer zoom lenses do not maintain perfect focus, but are still nearly parfocal. Most camera phones that are advertised as having optical zoom actually use a few cameras of different but fixed focal length, combined with digital zoom to make a hybrid system. The convenience of variable focal length comes at the cost of complexity – and some compromises on image quality, weight, dimensions, aperture, autofocus performance, and cost. For example, all zoom lenses suffer from at least slight, if not considerable, loss of image resolution at their maximum aperture, especially at the extremes of their focal length range. This effect is evident in the corners of the image, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   [Amazon] |

USB-C
USB-C, or USB Type-C, is a 24-pin reversible Electrical connector, connector (not a Communication protocol, protocol) that supersedes previous USB hardware#Connectors, USB connectors (also supersedes Mini DisplayPort and Lightning (connector), Lightning connectors) that can transfer data, e.g. audio/video data, to connect to monitors, external drives, mobile phones, keyboards/mouses, and many more peripheral devices; sometimes indirectly via hubs/docking stations. It also exchanges electricity, in general to power peripheral devices. It is used not only by USB technology, but also by other data transfer protocols, including Thunderbolt (interface), Thunderbolt, PCIe, HDMI, DisplayPort, and others. It is Extensibility, extensible to support future protocols. The design for the USB-C connector was initially developed in 2012 by Intel, HP Inc., Microsoft, and the USB Implementers Forum. The Type-C Specification 1.0 was published by the USB Implementers Forum (USB-IF) on August 11 ...

Micro-USB
The initial versions of the USB standard specified connectors that were easy to use and that would have high life spans; revisions of the standard added smaller connectors useful for compact portable devices. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data links. All versions of USB specify cable properties. Version 3.''x'' cables, marketed as ''SuperSpeed'', added a data link; namely, in 2008, USB 3.0 added a full-duplex lane (two twisted pairs of wires for one differential signalling, differential signal of serial data per direction), and in 2014, the USB-C specification added a second full-duplex lane. USB has always included some capability of providing power supply, power to peripheral devices, but the amount of power that can be provided has increased over time. The modern specifications are called ''USB Power Delivery'' (''USB PD'') and allow up to 240 watts, with or without data communications capabili ...

Mobile Phone Charger
A battery charger, recharger, or simply charger, is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging after the battery has been fully charged and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle. Other battery types use a timer to cut off when charging should be complete. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the stat ...

MicroB USB Plug
MicroB was a mobile web browser developed by Nokia for use in smartphones and mobile devices that run the Maemo operating system. The browser is Mozilla-based and uses the Gecko layout engine. It is shipped with Nokia's N800, N810 and N900 Internet Tablets, and is also available for the 770 via the ' Hacker Editions' of the operating system. In place of Mozilla's XUL-based user interface, MicroB uses the Maemo-native (GTK-based) Hildon API and widgets. History MicroB was initially released as a public beta for Internet Tablet OS 2007 on July 17, 2007 to allow third-party developers and community members to develop and port plugins, and help shape the development of the browser. It was updated several times before it replaced Opera as Internet Tablet OS's default browser with the release of Internet Tablet OS 2008 on November 18, 2007 with the N810. Architecture MicroB is Mozilla-based and uses the Gecko engine, but a number of features are omitted due to platform-spec ...

USB On-The-Go
USB On-The-Go (USB OTG or just OTG) is a specification first used in late 2001 that allows USB devices, such as tablets or smartphones, to also act as a host, allowing other USB devices, such as USB flash drives, digital cameras, mice or keyboards, to be attached to them. Use of USB OTG allows devices to switch back and forth between the roles of host and device. For example, a smartphone may read from removable media as the host device, but present itself as a USB Mass Storage Device when connected to a host computer. USB OTG introduces the concept of a device performing both Host and Peripheral roles whenever two USB devices are connected and one of them is a USB OTG device, they establish a communication link. The device controlling the link is called the Host, while the other is called the Peripheral. USB OTG defines two roles for devices: OTG A-device and OTG B-device, specifying which side supplies power to the link, and which initially is the host. The OTG A-device is ...

Photo Sharing
A photograph (also known as a photo, or more generically referred to as an ''image'' or ''picture'') is an image created by light falling on a photosensitivity, photosensitive surface, usually photographic film or an electronic image sensor. The process and practice of creating such images is called photography. Most photographs are now created using a smartphone or camera, which uses a photographic lens, lens to focus the scene's visible spectrum, visible wavelengths of light into a reproduction of what the human eye would perceive. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek language, Greek φῶς ('':el:phos, phos''), meaning "light", and γραφή (''graphê''), meaning "drawing, writing", together meaning "drawing with light". History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the Bitumen of Judea, bitumen-based "heliography" process developed by Nicéphore Niép ...

SD Card
Secure Digital (SD) is a proprietary, non-volatile, flash memory card format developed by the SD Association (SDA). Owing to their compact size, SD cards have been widely adopted in a variety of portable consumer electronics, including digital cameras, camcorders, video game consoles, mobile phones, action cameras, and camera drones. The SD format was introduced in August 1999 by SanDisk, Panasonic (then known as Matsushita), and Kioxia (then part of Toshiba). It was designed as a successor to the MultiMediaCard (MMC) format, introducing several improvements aimed at enhancing usability, durability, and performance, which contributed to its rapid emergence as an industry standard. To manage the licensing and intellectual property rights related to the format, the three companies established SD-3C, LLC. In January 2000, they also founded the SDA, a non-profit organization dedicated to developing and promoting SD card standards. As of 2023, the SDA includes approxima ...
