A smartphone is a mobile device that combines the functionality of a traditional mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing, email, and social media, as well as multimedia playback and streaming. Smartphones have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps.
The Palm Treo 650 is a Palm OS-based smartphone, the successor to Palm's Treo 600. It began shipping in November 2004, and was discontinued in 2008.
A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are usually not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This "fine line" distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile, unlike the hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light laptops, and the hybridization of the two in 2-in-1 PCs.
Nokia 5800 XpressMusic is a smartphone part of the XpressMusic line, announced by Nokia on 2 October 2008 in London and started shipping in November of that year. Code-named "Tube", it was the first touchscreen-equipped S60 device by Nokia – essentially it was the first device to run Symbian^1, also known as S60 5th Edition, the touch-specific S60-based platform created by the Symbian Foundation. The touchscreen features tactile feedback.
The HTC Dream is a smartphone developed by HTC. First released in September 2008 for $179 with a 2-year contract to T-Mobile, the Dream was the first commercially released device to use the Linux-based Android operating system, which was purchased and further developed by Google and the Open Handset Alliance to create an open competitor to other major smartphone platforms of the time, such as Symbian, BlackBerry OS, and iPhone OS. The operating system offers a customizable graphical user interface, integration with Google services such as Gmail, a notification system that shows a list of recent messages pushed from apps, and Android Market for downloading additional apps. This operating system's debut would later be followed by the Samsung Galaxy i7500, the first in what would become the long-running Samsung Galaxy series.
The form factor of a mobile phone is its size, shape, and style, as well as the layout and position of its major components.
The Samsung GT-I7500 Galaxy is a smartphone manufactured by Samsung that uses the open source Android operating system. It was announced on 27 April 2009 and was released on 29 June 2009 as the first Samsung Mobile device to use the Android operating system introduced in the HTC Dream, and the first in what would become the long-running Galaxy series. It was succeeded by the Samsung Galaxy S in 2010.
The LG VS740 is a mid-range smartphone manufactured by LG Electronics.
Rooting is the process by which users of Android devices can attain privileged control over various subsystems of the device, usually smartphones and tablets. Because Android is based on a modified version of the Linux kernel, rooting an Android device gives similar access to administrative (superuser) permissions as on Linux or any other Unix-like operating system such as FreeBSD or macOS.
The LG Optimus, also known as the LG Optimus GT540, LG GT540 Swift and the LG Loop GT540, is a mid-level Android smartphone designed and manufactured by LG Electronics. Released running Android 1.6 Donut, the device can be officially upgraded to Android 2.1 Eclair via an LG software release.
The hacking of consumer electronics is a common practice that users perform to customize and modify their devices beyond what is typically possible. This activity has a long history, dating from the days of early computer, programming, and electronics hobbyists.
The LG Optimus One is an entry-level series of touch-screen smartphones manufactured by LG Electronics, Inc. It was released running the Android 2.2 Froyo, and later LG released software to upgrade it to Android 2.3 Gingerbread. Although the basic physical form factor of each variant is the same, the variants have differences in hard button shape and layout, the form of the metal side bezel and the user interfaces added by LG or various carriers. Versions of the Optimus One exist that operate on various frequency bands and either GSM or CDMA-based network protocols. They may also feature one or more variations in hardware, such as a faster processor, the addition of a physical keyboard, a modem with higher theoretical speeds, or a better digital camera.
The LG Optimus 2X is a smartphone designed and manufactured by LG Electronics. The Optimus 2X is the world's first smartphone with a dual-core processor and the third phone in the LG Optimus-Android series. LG introduced the Optimus 2X on December 16, 2010 and the device first became available to consumers in South Korea in January 2011. It was also launched in Singapore on March 3, 2011. The Optimus 2X has run the Android 2.3 software version since the upgrade in November 2011, but the latest offering is Android 4.0. The phone holds the record for the longest update holdout, taking 16 months to receive a firmware update from Android 2.2 to 2.3.
Android software development is the process by which applications are created for devices running the Android operating system. Google states that "Android apps can be written using Kotlin, Java, and C++ languages" using the Android software development kit (SDK), while using other languages is also possible. All non-Java virtual machine (JVM) languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some programming languages and tools allow cross-platform app support. Third party tools, development environments, and language support have also continued to evolve and expand since the initial SDK was released in 2008. The official Android app distribution mechanism to end users is Google Play; it also allows staged gradual app release, as well as distribution of pre-release app versions to testers.
The LG P970 Optimus Black is a smartphone designed and manufactured by LG Electronics and was released in 2011. At 9.2 mm in thickness, it was LG's thinnest smartphone at the time of its release, and is slightly thinner than the iPhone 4. The LG Optimus Black features a WVGA NOVA display which has a brightness measured at 749 nits, which surpasses the 700 nits promised by LG.

The G2 is primarily distinguished by software features that LG billed would "learn" from users, a high fidelity sound system designed to produce higher quality audio, a 5.2 in (130 mm) 1080p IPS LCD screen with technology that the company claimed would improve energy efficiency and reduce the size of the bezel around it, along with the unique placement of its power and volume keys—eschewing their typical location on the edge of a smartphone by placing them on the rear below the camera lens.

It is succeeded by the Samsung Galaxy 3.
The PinePhone is a smartphone developed by Hong Kong–based computer manufacturer Pine64, designed to provide users with full control over the device. This is achieved through the utilization of mainline Linux-based mobile operating systems, assembly of the phone using screws, and facilitating simplified disassembly for repairs and upgrades. The 2G-4GLTE modem, GPS, Wi-Fi, Bluetooth and both cameras can be physically switched off. The PinePhone ships with the Manjaro Linux operating system using the Plasma Mobile graphic interface, although other distributions can be installed by users.
