On most modern flip phones, there is usually a small display on the back of the screen to indicate the time and any incoming calls/text messages whilst the phone is closed.
NOKIA CANDYBAR PHONE PORTABLE
When flipped shut, the phone becomes much smaller and more portable than when it is opened for use. When flipped open, the phone's screen and keyboard are available. Other models include Nokia 3300 and Nokia 5510.Ī flip or clamshell phone consists of two or more sections that are connected by hinges, allowing the phone to flip open then fold closed in order to become more compact. It was widely known as the plastic taco for its taco-shape and the placement of microphones on the side of the device, which, when one talks into the microphone, gives the appearance of eating a taco. The taco form factor was popularized by the Nokia N-Gage, released in 2003. Back part of display can be used as viewfinder for selfies and videocalls. Xiaomi revealed Mi MIX Alpha, a smartphone with a display that surrounds almost entirely its body, only interrupted in the back part by a column that contains the cameras. The Nubia X, Nubia Z20 and Vivo NEX Dual Display have solved this combining the use of the main camera and a smaller second rear screen, eliminating the front camera. The presence of the front camera for taking selfies has been an essential feature in smartphones, however, it is a difficulty to achieve a bezelless screen as is the trend in the later 2010s. In the case of Yotaphone and Siam 7X, they have normal touchscreens on the front, but on the backside is an e-ink screen, which enables using the cases in a fashion similar to reading a book. Other multi-screen form factors has screens on both sides of the phone. Some have a small separate screen above the main screens, the LG V10 and LG V20.
The multi-screen is of basically the slate form factor, but with two touchscreens.
NOKIA CANDYBAR PHONE WINDOWS
Nokia Lumia 1520, a Windows Phone phablet Some unusual "slate" designs include that of LG New Chocolate (BL40), or the Samsung Galaxy Round, which is curved. The iPhone, which was released by Apple in 2007, is largely responsible for the influence and achievement of this design as it is currently conceived. The first commercially available touchscreen phone was a brick phone, the IBM Simon Personal Communicator, released in 1994.
Slate Ī slate is a smartphone form with few to no physical buttons, instead relying upon a touchscreen and an onscreen virtual keyboard for input. For example, "I bricked my MP3 player when I tried to modify its firmware." It can also be used as a noun, for example, "If it's corrupted and you apply using fastboot, your device is a brick." In the common usage of the term, "bricking" suggests that the damage is so serious as to have rendered the device permanently unusable. The term derives from the vaguely cuboid shape of many electronic devices (and their detachable power supplies) and the suggestion that the device can function only as a lifeless, square object, paperweight or doorstop.
The term "brick" has also expanded beyond smartphones to include most non-working consumer electronics, including a game console, router, or other device, that, due to a serious misconfiguration, corrupted firmware, or a hardware problem, can no longer function, hence, is as technologically useful as a brick. However, "brick" has more recently been applied to older phone models in general, including non-bar form factors (flip, slider, swivel, etc.), and even early touchscreen phones as well, due to their size and relative lack of functionality compared to current models on the market.
