A feature phone is a class of mobile phone; the term is typically used as a retronym to describe low-end mobile phones which are limited in capabilities in contrast to a modern smartphone. Feature phones typically provide voice calling and text messaging functionality, in addition to basic multimedia and internet capabilities, and other services offered by the user's wireless service provider. In an effort to provide parity with smartphones, modern feature phones have also incorporated support for 3G connectivity, touchscreens, and access to popular social networking services. However, their functionality and support for third-party software are still relatively limited in comparison to smartphones – as a result of this contrast, some feature phones are also referred to as dumb phones. Feature phones are marketed as a lower-cost alternative to smartphones, especially in emerging markets. However, even in these markets, manufacturers have, in recent years, begun to produce and sell low-cost smartphones in an effort to tap into markets where adoption of high-end smartphones has been low. Hence, , feature phones have been completely relegated to the ultra-low-end category.〔(【引用サイトリンク】title=Jivi Launches 'Cheapest Android-Based Smartphone in India' at Rs. 1,999 )〕 ==History== The category of feature phones is distinct from smartphones, and refers primarily to low-range phones, ranging from basic phones on the low end (few or no features beyond basic dialing and messaging) to smartphones on the high end. Prior to the popularity of smartphones, the term may be applicable to high-end phones with assorted features. These developed and peaked in popularity during the 2000s, contemporary with 3G networks, which allowed sufficient bandwidth for these features. Since the popularization of smartphones in the late 2000s, feature phones have been replaced in most of the world at the high end with smartphones, though particular features may be found on either feature phones or smartphones. In Japan, mobile phones developed a wide array of features prior to the development of smartphones. The introduction of smartphones has largely displaced these at the high end, though smartphones for the Japanese market often include features first developed on feature phones. Many of these features were and remain specific to Japan, often requiring network support, and the resulting phones, while dominant in Japan, proved unsuccessful abroad. This led to the term "Galápagos syndrome" – specialized development dominant on an island, but not found abroad – and then lead to the term , blending Galapagos with , to refer to Japanese feature phones, by contrast with smartphones. In 2014, Japan shipped 10.58 million units of ''garakei'', a 5% increase over 2013; durability and long battery life account for part of their rise in popularity.〔(In Japan, People Are Flipping Out Over The Flip-Phone (Galapagos Phone): What's Old Is New Again ) Retrieved 13 August 2015.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「feature phone」の詳細全文を読む スポンサード リンク
