It is most commonly used in [camera phones](/source/Camera_phone). ## Advantages The main advantage of using a dual fronted device is the enhanced ease of use by having distinctive functions for each side. For example, having a mobile phone with a dual front for the camera encourages the user to hold the phone horizontally which reduces the learning curve because the buttons and functions are located in similar places to a common [digital camera](/source/Digital_camera). [1] ## Use in market Front side of Sony Ericsson K700i. The rear is designed similarly to Sony's [Cyber-shot](/source/Cyber-shot) cameras. The dual front concept began in 2003 when [Sony Ericsson](/source/Sony_Ericsson) started its camera phone range with the [T610](/source/T610) and T630 which could be held comfortably in the style of a real digital camera due to its side-mounted shutter button; they also had rear designs which loosely resembled the design of digital cameras. Sony Ericsson described the design of the T630 as 'Putting an end to phones having a front and a back, **the T630 has two sides**. One for the camera... the other for telephony...'[2] With the announcement of the [K700i](/source/K700i) and [S700i](/source/S700i), Sony Ericsson introduced a new marketing term, "Dual front" to refer to camera phone where the "back" of the handset is styled as the "front" of a digital camera, hence the term of "dual front".[3] The market responded well to this design and [Sharp](/source/Sharp_Corporation) was the next company to begin designing dual front products, by producing a [clamshell phone](/source/Clamshell_phone) with a dual front design ([Sharp 902](https://en.wikipedia.org/w/index.php?title=Sharp_902&action=edit&redlink=1)).[4] This had not been done before on clamshell phones as it was difficult to find a convenient location to put the camera due to the physical limitations. [Nokia](/source/Nokia), after observing the continued response towards mobile phones with dual front designs announced the [6111](/source/Nokia_6111)[5] and the [6270](/source/Nokia_6270)/[6280](/source/Nokia_6280) in 2005,[6] all of which had a dual front element to them. They had also previously created a new design which involved the twisting of the top flip in order to create a [camcorder](/source/Camcorder) like display (as on the [6260](https://en.wikipedia.org/w/index.php?title=6260&action=edit&redlink=1)).[7] Whilst not strictly dual front, it was later elaborated more to form the [N90](/source/Nokia_N90), [N92](/source/Nokia_N92) and [N93](/source/Nokia_N93). [Samsung](/source/Samsung)'s [UpStage](https://en.wikipedia.org/w/index.php?title=Samsung_UpStage&action=edit&redlink=1), released in 2007, features a new form of dual front design, where one side is the phone side and the other side resembles an [MP3 player](/source/MP3_player).[8] ## Other uses Sony Ericsson also used the dual front design in the Japan release, the Sony Ericsson Radiden. On the back it had a separate screen for accessing radio functions.[9] ## References 1. **[^](#cite_ref-1)** ["Sony Ericsson unveils the S700 – an innovatively designed megapixel camera phone with a new communication style"](http://www.sonyericsson.com/cws/corporate/press/pressreleases/pressreleasedetails/1491sonyericssonunveilsthes700aninnov-20040309) *[Sony Ericsson](/source/Sony_Ericsson)*.
