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 also have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps.
A mobile operating system is an operating system 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 generally not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This 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 hardware of the past. Key notabilities blurring this line are the introduction of tablet computers and light-weight laptops and the hybridization of the two in 2-in-1 PCs.
The Samsung Behold SGH-T919 is a touch-screen, 3G candybar-style smartphone introduced by Samsung late in 2008. The Behold is one of the first Samsung mobile phones released to have a touch-screen along with the Samsung Omnia, the Samsung Instinct, the Samsung Eternity, and the Samsung Tocco. The Behold is the "American" release of Samsung Tocco, which is only sold in Europe, Asia and Australia so the features and design of both of these phones are similar. Some of the Behold's biggest competitors were Apple's iPhone, T-Mobile G1, LG Dare, Samsung Instinct, and Samsung Eternity. It was only available only to customers of T-Mobile.
A dual-touchscreen is a computer or phone display setup which uses two screens, either or both of which could be touch-capable, to display both elements of the computer's graphical user interface and virtualized implementations of common input devices, including virtual keyboards. Usually, in a dual-touchscreen computer or computing device, the most persistent GUI elements and functions are displayed on one, hand-accessible touchscreen alongside the virtual keyboard, while the other, more optically-centric display is used for those user interface elements which are either less or never accessed by user-generated behaviors.

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.

First unveiled by the company on October 27, 2013 for a release in South Korea, and carrying similarities to its G2 model, the smartphone is the company's first to incorporate a flexible display, along with a "self-healing" rear cover which can repair minor abrasions on its own.

LG also touted the device's plastic "metallic skin"—designed to give the device a higher quality appearance, and a "simpler" user interface with an integrated intelligent personal assistant system. The battery can be quickly changed by the user, allowing charged spare batteries to be carried.
The Samsung Galaxy S6 is a line of Android-based smartphones manufactured, released and marketed by Samsung Electronics. Succeeding the Samsung Galaxy S5, the S6 was not released as a singular model, but instead in two variations unveiled and marketed together—the Galaxy S6 and Galaxy S6 Edge—with the latter differentiated primarily by having a display that is wrapped along the sides of the device. It is distinguished from its predecessor through a battery with an increased charging speed but a decreased capacity, an optically stabilized camera, sound in slow motion video recordings, a glass back, and it lacks a user-replaceable battery, a memory card slot, water resistance, and MHL-to-HDMI connection for viewing on an external monitor or television set.

Two modules are available: a camera grip, and a high-fidelity audio module with DAC. A lower-spec variation, dubbed the LG G5 SE, is available in some markets.
