The functions of feature phones are limited compared to smartphones: they tend to use an embedded operating system with a small and simple graphical user interface (unlike large and complex mobile operating systems on a smartphone) and cover general communication basics, such as calling and texting by SMS, although some may include limited smartphone-like features as well.<ref name=":0">{{Cite news |last=Wiseman |first=Ed |date=2018-10-23 |title=The best dumbphones for a digital detox, tried and tested |url=https://www.telegraph.co.uk/recommended/tech/best-basic-phones-dumbphones/ |access-date=2025-05-01 |work=The Telegraph |language=en-GB |issn=0307-1235}}</ref> Additionally, they may also evoke the form factor of earlier generations of mobile phones, typically from the 1990s and 2000s, with press-button based inputs and a small non-touch display.

Depending on extent of functionality, feature phones may have many of the capabilities of a smartphone, within certain cases. The hardware of feature phones often includes a backlit liquid-crystal display (LCD) screen, a hardware notification LED, a micro USB port, a physical keyboard, a microphone, a microSD card slot, a rear-facing camera to record video and capture pictures, and GPS services. Some feature phones include a rudimentary app store that includes basic mobile apps such as a calendar, calculator, mobile web, and mobile games.<ref>{{Cite web|last=Hardy|first=Ed|date=25 March 2003|url=http://www.Brighthand.com/article/Study_Says_Smartphones_Will_Outsell_Handhelds/|title=Study says: smartphones will outsell handhelds this year|website=Brighthand.com|publisher=Brighthand – TechTarget|access-date=13 February 2021|quote=The European analyst firm Canalys has released a study that predicts shipments of smartphones will exceed those of handhelds in the Europe, Middle East, and Africa (EMEA) region for the first time in 2003.

Following the rise of smartphones, the feature phone has sometimes been referred to as a dumbphone.<ref name="tny-dumbphone-boom" />
The first GSM phones and many feature phones had NOR flash memory, from which processor instructions could be executed directly in an execute in place architecture and allowed for short boot times. With smartphones, NAND flash memory was adopted as it has larger storage capacities and lower costs, but causes longer boot times because instructions cannot be executed from it directly, and must be copied to RAM first before execution.<ref>{{cite book | url=https://books.google.com/books?id=vaq11vKwo_kC&dq=nand+flash+copy+sram&pg=PA12 | title=Inside NAND Flash Memories | isbn=978-90-481-9431-5 | last1=Micheloni | first1=Rino | last2=Crippa | first2=Luca | last3=Marelli | first3=Alessia | date=27 July 2010 | publisher=Springer }}</ref>

A well-specified feature phone can be used in industrial environments, and the outdoors, at workplaces that proscribe dedicated cameras, and as an emergency telephone. Several models are equipped with hardware functions; such as FM radio and flashlight, that prevent the device from becoming useless in the event of a major disaster, or entirely obsolete, if and when 2G network infrastructure is shut down. Other feature phones are specifically designed for the elderly, and yet others for religious purposes.<ref>{{Cite web|last=Hirshfeld|first=Rachel|date=26 March 2012|url=https://www.IsraelNationalNews.com/News/News.aspx/154153|title=Introducing: a 'kosher phone' permitted on shabbat – the Zomet Institute has released a kosher telephone that can be used on Shabbat without breaking the Jewish laws of the day of rest.|website=www.IsraelNationalNews.com|publisher=Israel National News – Arutz Sheva|access-date=13 February 2021}}</ref> In Pakistan and other South Asian countries, many mobile phone outlets use feature phones for balance transfer, referred to as Easyload.<ref>{{Cite web | url=https://www.telenor.com.pk/easyload/#:~:text=With%20Telenor's%20easyload%20you%20can,as%20per%20your%20price%20plan. | title=Easyload | access-date=23 February 2022 | archive-date=5 April 2023 | archive-url=https://web.archive.org/web/20230405054727/https://www.telenor.com.pk/easyload/#:~:text=With%20Telenor's%20easyload%20you%20can,as%20per%20your%20price%20plan. | url-status=dead }}</ref> [[File:HMDBarbie.png|thumb|Recent feature phones in the 2020s such as this officially licensed HMD Barbie have been marketed specially against smartphone addiction.]] In the late 2010s and early 2020s, multiple new companies were formed specifically to manufacture and sell such phones in North America.

Existing feature phone operating systems at the time were not designed to handle additional tasks beyond communication and basic functions, and due to the complex bureaucracy and other factors, they never developed a thriving software ecosystem.<ref name=PixelsTech/>
By contrast, iPhone OS (renamed iOS in 2010) and Android were designed as a robust operating system, embracing third-party software, and having capabilities such as multitasking and graphics capabilities in order to meet future consumer demands.<ref>{{Cite news |url= https://www.TheGlobeAndMail.com/globe-investor/rims-long-road-to-reinvent-the-blackberry/article7901031/ |first=Iain |last=Marlow |title=RIM's long road to reinvent the BlackBerry |work=The Globe and Mail |location= Toronto |date=27 January 2013 |access-date=16 August 2013}}</ref> These platforms also eclipsed the popularity of smartphone platforms historically aimed towards enterprise markets, such as BlackBerry.<ref>{{Cite news|author=Jason Perlow|date=8 November 2009|url=https://www.zdnet.com/article/in-smartphone-wars-darwinism-triumphs-over-intelligent-design/|title=In smartphone wars, Darwinism triumphs over intelligent design|website=www.ZDNet.com|publisher=ZDNet|access-date=}}</ref>
There has been an industry shift from feature phones (including low-end smartphones), which rely mainly on volume sales, to high-end flagship smartphones, which also enjoy higher margins, thus manufacturers find high-end smartphones much more lucrative than feature phones.<ref>{{Cite web|author=Ashraf Eassa|date=12 February 2013|url=http://SeekingAlpha.com/article/1173911-nokia-s-lumia-strategy-will-pay-off-nicely|title=Nokia's Lumia strategy will pay off nicely|website=SeekingAlpha.com|publisher=Seeking Alpha|access-date= }}</ref><ref>{{Cite web|author=Chris Smith|date=24 December 2012|url=http://www.androidauthority.com/galaxy-s4-spearhead-impressive-samsung-year-company-sell-390-million-smartphones-2013-142489/|title=Galaxy S4 to spearhead impressive Samsung year, company to sell 390 million smartphones in 2013|website=www.AndroidAuthority.com|publisher=Android Authority|access-date=|archive-date=28 June 2021|archive-url=https://web.archive.org/web/20210628200329/https://www.androidauthority.com/galaxy-s4-spearhead-impressive-samsung-year-company-sell-390-million-smartphones-2013-142489/|url-status=dead}}</ref>
The shift away from feature phones has forced mobile network operators to increase subsidies of handsets, and the high selling-prices of flagship smartphones have had a negative effect on the mobile network operators, who have seen their earnings before interest, taxes, depreciation, and amortisation (EBITDA) margins drop as they sold more smartphones and fewer feature phones. To help make up for this, carriers typically use high-end devices to upsell customers onto higher-priced service plans with increased data allotments.<ref>{{Cite web|last=Goldman|first=David|date=8 February 2012|url=https://Money.CNN.com/2012/02/08/technology/iphone_carrier_subsidy/index.htm|title=Apple's subsidy makes iPhone a nightmare for carriers|website=Money.CNN.com|publisher=CNN Money|access-date=16 August 2013}}</ref><ref>{{Cite news |url= https://www.TheGlobeAndMail.com/report-on-business/international-business/sprint-nextel-apple-drinks-the-juice/article544696/ |title=Sprint Nextel: Apple drinks the juice |work=The Globe and Mail |location= Toronto |date=9 February 2012 |access-date=16 August 2013}}</ref><ref>{{Cite web|last=Gustin|first=Sam|url=https://Business.Time.com/2012/02/08/how-apples-iphone-actually-hurts-att-verizon-and-sprint/|title=How Apple's iPhone actually hurts AT&T, Verizon and Sprint|magazine=Time|date=8 February 2012|access-date=16 August 2013}}</ref> Trends have shown that consumers are willing to pay more for smartphones that include newer features and technology, and that smartphones were considered to be more relevant in present-day popular culture than feature phones.<ref name=eWeek>{{Cite magazine|last=Reisinger|first=Don|date=15 August 2013|url=https://www.eWeek.com/mobile/slideshows/smartphones-sales-finally-overtake-feature-phones-10-reasons-why/|title=Smartphones sales finally overtake feature phones: 10 reasons why|website=www.eWeek.com|publisher=eWeek|access-date= }}</ref>

A survey of 4,001 Canadians by Media Technology Monitor (MTM) in late 2012 suggested about 83 percent of the anglophone population owned a cellphone, up from 80 percent in 2011 and 74 percent in 2010. About two thirds of the mobile phone owners polled said they had a smartphone, and the other third had feature phones or non-smartphones. According to MTM, non-smartphone users are more likely to be female, older, have a lower income, live in a small community, and have less education. The survey found that smartphone owners tend to be male, younger, live in a high-income household with children in the home, and residents of a community of one million or more people.

===Japan=== Mobile phones in Japan diverged from those used elsewhere, with carriers and devices often implementing advanced features – such as NTT DoCoMo's i-mode platform for mobile internet in 1999, mobile payments, mobile television, and near field communications – that were not yet widely used, or even adopted, outside of Japan.
