The form factor of a mobile phone is its size, shape, and style, as well as the layout and position of its major components.

Brick

"Brick" is a slang term used to refer to large, outdated rectangular phones, typically early devices with large batteries and electronics. These early phones, such as the Motorola DynaTAC, have been displaced by newer smaller models which offer greater portability thanks to smaller antennas and slimmer battery packs. 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. The term "brick" has also expanded beyond smartphones to include most non-working

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.

and LG V20. Other multi-screen form factors has screens on both sides of the phone. 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. 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. 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.

Wrapped-around display

With movable sections

Flip

A 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. When flipped open, the phone's screen and keyboard are available. When flipped shut, the phone becomes much smaller and more portable than when it is opened for use.

and Bang & Olufsen. Clamshell came to be used as generic for this form factor. Flip phone referred to phones that opened on the vertical axis. As clamshells disappeared from the market, the terms again became disambiguated.

Slider

A slider is composed of usually two, but sometimes more, sections that slide past each other on rails. Most slider phones have a display segment which houses the device's screen, while another segment contains the keypad or keyboard and slides out for use. The goal of a sliding form factor is to allow the operator to take advantage of full physical keyboards or keypads, without sacrificing portability, by ''retracting'' them into the phone when they are not in use. Many different companies have developed smartphones that slide: Samsung has the Corby and BlackBerry has the Torch. The
