By the mid-2000s, higher-end [[cell phones]] commonly had integrated digital cameras. In 2003 [[camera phone]]s outsold stand-alone digital cameras, and in 2006 they outsold film and digital stand-alone cameras. Five billion camera phones were sold in five years, and by 2007 more than half of the [[installed base]] of all mobile phones were camera phones. Sales of separate cameras peaked in 2008.<ref name="SmartphonesTollonGPS">{{cite web |last=O'Brien |first=Kevin J. |title=Smartphone Sales Taking Toll on G.P.S.

Many early smartphones did not have cameras at all, and earlier models that had them had low performance and insufficient image and video quality that could not compete with budget pocket cameras and fulfill user's needs.<ref name=Nokia6111>{{Cite web|url=https://www.gsmarena.com/nokia_6111-review-61.php|title=Nokia 6111 review: Venus and maybe Mars too|website=GSMArena.com}}</ref> By the beginning of the 2010s almost all smartphones had an integrated digital camera. The decline in sales of stand-alone cameras accelerated due to the increasing use of smartphones with rapidly improving camera technology for casual photography, easier [[Digital image processing|image manipulation]], and abilities to directly [[Image sharing|share photos]] through the use of [[Mobile app|apps]] and web-based services.<ref name="SmartphonesKillingPoint-and-shoots">{{cite web |last=Ogg |first=Erica |title=Smartphones killing point-and-shoots, now take almost 1/3 of photos |url=https://gigaom.com/2011/12/22/smartphones-killing-point-and-shoots-now-take-almost-13-of-photos/ |website=Gigaom |date=December 22, 2011 |access-date=October 22, 2019 |archive-date=July 14, 2019 |archive-url=https://web.archive.org/web/20190714065702/https://gigaom.com/2011/12/22/smartphones-killing-point-and-shoots-now-take-almost-13-of-photos/ |url-status=dead }}</ref><ref>{{cite web |last=Siegler |first=MG |title=iPhone 4 About To Be Flickr's Top Camera.

Contributing to the rise in popularity of smartphones being used over dedicated cameras for photography, smaller pocket cameras have difficulty producing [[bokeh]] in images, but nowadays, some smartphones have dual-lens cameras that reproduce the bokeh effect easily, and can even rearrange the level of bokeh after shooting. This works by capturing multiple images with different focus settings, then combining the background of the main image with a [[Macro photography|macro focus shot]].

In 2007, the [[Nokia N95]] was notable as a smartphone that had a 5.0 [[Megapixel]] (MP) camera, when most others had cameras with around 3 MP or less than 2 MP. Some specialized feature phones like the [[LG Viewty]], [[Samsung SGH-G800]], and [[Sony Ericsson K850i]], all released later that year, also had 5.0 MP cameras. By 2010, 5.0 MP cameras were common; a few smartphones had 8.0 MP cameras and the [[Nokia N8]], [[Sony Ericsson Satio]],<ref>{{cite web |url=http://www.newtechnology.co.in/sony-ericsson-satio-a-phone-with-ultimate-multimedia-experience/ |title=Sony Ericsson Satio – A Phone with Ultimate multimedia experience |publisher=Newtechnology.co.in |access-date=June 21, 2013 |url-status=live |archive-url=https://web.archive.org/web/20120714020642/http://www.newtechnology.co.in/sony-ericsson-satio-a-phone-with-ultimate-multimedia-experience/ |archive-date=July 14, 2012 }}</ref> and [[Samsung M8910 Pixon12]]<ref>{{cite web |url=http://www.newtechnology.co.in/samsung-pixon12-m8910-worlds-first-12-megapixel-camera-phone/ |title=Samsung Pixon12 M8910 Price in India - 12 megapixel camera-phone |publisher=Newtechnology.co.in |access-date=June 21, 2013 |url-status=live |archive-url=https://web.archive.org/web/20120424142402/http://www.newtechnology.co.in/samsung-pixon12-m8910-worlds-first-12-megapixel-camera-phone/ |archive-date=April 24, 2012 }}</ref> feature phone had 12 MP.

The Altek Leo, a 14-megapixel smartphone with 3x optical zoom lens and 720p HD video camera was released in late 2010.<ref>{{cite web |last=Chan |first=John |title=Hands-on with the 14-megapixel Altek Leo |url=http://asia.cnet.com/crave/hands-on-with-the-14-megapixel-altek-leo-62111524.htm |publisher=CBS Interactive |work=CNET |date=June 15, 2010 |url-status=dead |archive-url=https://web.archive.org/web/20120403042848/http://asia.cnet.com/crave/hands-on-with-the-14-megapixel-altek-leo-62111524.htm |archive-date=April 3, 2012}}</ref>

In 2011, the same year the [[Nintendo 3DS]] was released, HTC unveiled the [[HTC Evo 3D|Evo 3D]], a [[3D phone]] with a dual five-megapixel rear camera setup for spatial imaging, among the earliest [[:Category:Mobile phones with multiple rear cameras|mobile phones with more than one rear camera]].

The 2012 [[Samsung Galaxy S III#Camera|Samsung Galaxy S3]] introduced the ability to capture photos using [[Voice user interface|voice commands]].<ref>{{Cite web|last=Cozma|first=Nicole|title=Use your voice to take pictures with the Samsung Galaxy S III|url=https://www.cnet.com/how-to/use-your-voice-to-take-pictures-with-the-samsung-galaxy-s-iii/|access-date=2021-05-29|website=CNET }}</ref>

In 2012, Nokia announced and released the [[Nokia 808 PureView]], featuring a 41-megapixel 1/1.2-inch sensor and a high-resolution f/2.4 [[Carl Zeiss AG|Zeiss]] all-aspherical one-group lens. The high resolution enables four times of lossless [[digital zoom]] at 1080p and six times at 720p resolution, using [[Digital zoom#Not-deteriorated zoom limit|image sensor cropping]].<ref>{{cite web |title=Nokia 808 PureView review: Photo Finnish |url=https://www.gsmarena.com/nokia_808_pureview-review-776p7.php |website=GSMArena.com |page=7 |date=2012-06-22}}</ref> The 2013 [[Nokia Lumia 1020]] has a similar high-resolution camera setup, with the addition of [[optical image stabilization]] and manual camera settings years before common among high-end mobile phones, although lacking [[#Memory_cards|expandable storage]] that could be of use for accordingly high [[file size]]s.

Mobile [[optical image stabilization]] was first introduced by Nokia in 2012 with the [[Lumia 920]], and the earliest known smartphone with an optically stabilized front camera is the [[HTC 10]] from 2016.<ref>{{cite web |last1=Dobie |first1=Alex |title=HTC 10 review: Iconic, impressive, imperfect |url=https://www.androidcentral.com/htc-10 |website=Android Central |access-date=16 May 2023 |language=en |date=19 April 2016}}</ref> Optical image stabilization enables prolonged [[exposure time]]s for low-light photography and smoothing out handheld video shaking, since the appearance of shakes magnifies over a larger display such as a [[computer monitor|monitor]] or [[television set]], which would be detrimental to the watching experience.

Since 2012, smartphones have become increasingly able to capture photos while filming. The resolution of those photos resolution may vary between devices. Samsung has used<!-- source does not mention whether they still do --> the highest image sensor resolution at the video's aspect ratio, which at 16:9 is 6 Megapixels (3264 × 1836) on the [[Galaxy S3]] and 9.6 Megapixels (4128 × 2322) on the [[Galaxy S4]].<ref name="761p9">{{Cite web|url=https://www.gsmarena.com/samsung_i9300_galaxy_s_iii-review-761p9.php|title=Samsung I9300 Galaxy S III review: S to the third |page=9 |website=GSMArena.com |date=2012-05-20}}</ref><ref>{{Cite web|url=https://www.gsmarena.com/samsung_galaxy_s4-review-914p9.php|title=Samsung Galaxy S4 review: Supernova|page=9 |website=GSMArena.com |date=2013-03-28}}</ref> The earliest iPhones with such functionality, [[iPhone 5]] and [[iPhone 5s|5s]], captured simultaneous photos at 0.9 Megapixels (1280 × 720) while filming.<ref>{{cite web |title=Snap Photos and Record Video on an iPhone at the Same Time |url=https://www.lifewire.com/take-photo-while-recording-video-iphone-1999621 |website=Lifewire |first1=sam|last1=Costello |date=2020-01-22}}</ref>

Starting in 2013 on the [[Xperia Z1]], Sony experimented with real-time [[augmented reality]] camera effects such as floating text, virtual plants, volcano, and a dinosaur walking in the scenery.<ref>{{cite web |title=Sony Xperia Z1 review: A smartphone with a camera-sized sensor |url=https://www.dpreview.com/reviews/sony-xperia-z1-camera-review/5 |website=DPReview |date=2013-11-01}}</ref> Apple later did similarly in 2017 with the [[iPhone X]].<ref>{{cite web |last1=Carson |first1=Biz |title=Tim Cook Isn't Wrong: Why The iPhone X Could Change How We Use Phones Forever |url=https://www.forbes.com/sites/bizcarson/2017/09/12/tim-cook-isnt-wrong-why-the-iphone-x-could-change-how-we-use-phones-forever/ |website=Forbes |date=2017-09-12}}</ref>

In the same year, [[iOS 7]] introduced the later widely implemented viewfinder intuition, where [[exposure value]] can be adjusted through vertical swiping, after focus and exposure has been set by tapping, and even while locked after holding down for a brief moment.<ref>{{cite web |title=How to control focus and depth of field on your iPhone camera |url=https://www.macworld.com/article/222584/how-to-control-focus-and-depth-of-field-on-your-iphone-camera.html |website=Macworld |date=2014-01-05}}</ref> On some devices, this intuition may be restricted by software in video/slow motion modes and for front camera.

In 2013, Samsung unveiled the [[Samsung Galaxy S4 Zoom|Galaxy S4 Zoom]] smartphone with the grip shape of a [[compact camera]] and a 10× [[optical zoom]] lens, as well as a rotary knob ring around the lens, as used on higher-end compact cameras, and an ''[[ISO 1222]]'' tripod mount. It is equipped with manual parameter settings, including for focus and exposure. The successor 2014 [[Samsung Galaxy K Zoom]] brought resolution and performance enhancements, but lacks the rotary knob and tripod mount to allow for a more smartphone-like shape with less protruding lens.<ref>{{cite web |title=Samsung Galaxy K Zoom vs Galaxy S4 Zoom: What's the difference? |url=https://www.pocket-lint.com/phones/buyers-guides/samsung/128613-samsung-galaxy-k-zoom-vs-galaxy-s4-zoom-what-s-the-difference |website=www.pocket-lint.com |access-date=20 April 2021 |date=29 April 2014}}</ref>

The 2014 [[Panasonic Lumix DMC-CM1]] was another attempt at mixing mobile phone with compact camera, so much so that it inherited the [[Lumix]] brand. While lacking optical zoom, its image sensor has a [[image sensor format|format]] of 1", as used in high-end compact cameras such as the [[Lumix DMC-LX100]] and [[Sony CyberShot DSC-RX100]] series, with multiple times the surface size of a typical mobile camera image sensor, as well as support for light sensitivities of up to ISO 25600, well beyond the typical mobile camera light sensitivity range. {{As of|2021}}, no successor has been released.<ref>{{cite web |title=Panasonic Lumix DMC-CM1 camera review |url=https://www.dpreview.com/reviews/panasonic-lumix-dmc-cm1-camera-review/10 |website=DPReview |access-date=20 April 2021 |page=10 |date=2015-05-27}}</ref><ref>{{cite web |last1=Brawley |first1=William |title=Panasonic CM1 Review |url=https://www.imaging-resource.com/PRODS/panasonic-cm1/panasonic-cm1A.HTM |website=Imaging Resource |access-date=20 April 2021 |date=2015-04-27}}</ref>

In 2013 and 2014, HTC experimentally traded in pixel count for pixel surface size on their [[HTC One M7|One M7]] and [[HTC One M8|M8]], both with only four megapixels, marketed as ''UltraPixel'', citing improved brightness and less noise in low light, though the more recent One M8 lacks [[optical image stabilization]].<ref>{{cite web |title=UltraPixel Camera Image Quality Review |url=https://www.trustedreviews.com/reviews/htc-one-m8-ultrapixel-camera-image-quality-page-7 |website=Trusted Reviews |page=7 |date=2016-11-18}}</ref>

The One M8 additionally was one of the earliest smartphones to be equipped with a [[Stereo camera|dual camera]] setup. Its software allows generating visual spatial effects such as 3D panning, weather effects, and focus adjustment ("UFocus"), simulating the postphotographic selective focusing capability of images produced by a [[Light field camera|light-field camera]].<ref>{{cite web |last1=Savvides |first1=Lexy |title=HTC One M8: the camera review |url=https://www.cnet.com/news/htc-one-m8-the-camera-review/ |website=CNET |language=en |date=2014-04-10}}</ref> HTC returned to a high-megapixel single-camera setup on the 2015 [[HTC One M9|One M9]].

Meanwhile, in 2014, LG Mobile started experimenting with [[time-of-flight camera]] functionality, where a rear [[laser]] beam that measures distance accelerates autofocus.

[[Phase-detection autofocus]] was increasingly adapted throughout the mid-2010s, allowing for quicker and more accurate focusing than [[contrast-detection autofocus|contrast detection]].

In 2016, [[Apple Inc.|Apple]] introduced the [[iPhone 7 Plus]], one of the phones to popularize a dual camera setup. The [[iPhone 7 Plus]] included a main 12 MP camera along with a 12 MP telephoto camera.<ref>{{cite web |last=Cade |first=DL |title=Apple Just Released Their Fake Bokeh Portrait Mode to Everyone |url=https://petapixel.com/2016/10/24/apple-just-released-fake-bokeh-portrait-mode-everyone/ |website=PetaPixel |date=October 24, 2016 |access-date=November 5, 2019}}</ref> In early 2018 [[Huawei]] released a new flagship phone, the [[Huawei P20|Huawei P20 Pro]], one of the first triple camera lens setups with [[Leica Camera|Leica]] optics.<ref>{{cite web |url=https://www.digitaltrends.com/cell-phone-reviews/huawei-p20-pro-review/#/2/1 |title=Huawei P20 Pro review |first=Andy |last=Boxall |date=June 4, 2018}}</ref> In late 2018, [[Samsung]] released a new mid-range smartphone, the [[Samsung Galaxy A9 (2018)|Galaxy A9 (2018)]] with the world's first quad camera setup.

2019 saw the commercialization of high resolution sensors, which use [[Bayer filter|pixel binning]] to capture more light. 48 MP and 64 MP sensors developed by Sony and Samsung are commonly used by several manufacturers. 108 MP sensors were first implemented in late 2019 and early 2020.

With stronger getting chipsets to handle computing workload demands at higher pixel rates, mobile video resolution and framerate has caught up with dedicated consumer-grade cameras over years.

In 2009, the [[Samsung i8910 Omnia HD|Samsung Omnia HD]] became the first mobile phone with [[720p]] HD video recording. In the same year, Apple brought video recording initially to the [[iPhone 3GS]], at 480p, whereas the 2007 [[IPhone (1st generation)|original iPhone]] and 2008 [[iPhone 3G]] lacked video recording entirely.

720p was more widely adapted in 2010, on smartphones such as the original [[Samsung Galaxy S (2010 smartphone)|Samsung Galaxy S]], [[Sony Ericsson Xperia X10]], [[iPhone 4]], and [[HTC Desire HD]].

The early 2010s brought a steep increase in mobile video resolution. [[1080p]] mobile video recording was achieved in 2011 on the [[Samsung Galaxy S II|Samsung Galaxy S2]], [[HTC Sensation]], and [[iPhone 4s]].

In 2012 and 2013, select devices with 720p filming at 60 frames per second were released: the [[Asus PadFone|Asus PadFone 2]] and [[HTC One (M7)|HTC One M7]], unlike flagships of Samsung, Sony, and Apple. However, the 2013 [[Samsung Galaxy S4 Zoom]] does support it.

In 2013, the [[Samsung Galaxy Note 3]] introduced [[2160p]] (4K) video recording at 30 [[Frame rate|frames per second]], as well as 1080p doubled to 60 [[Frame rate|frames per second]] for smoothness.

Other vendors adapted 2160p recording in 2014, including the [[optical image stabilization|optically stabilized]] [[LG G3]]. Apple first implemented it in late 2015 on the [[iPhone 6s]] and 6s Plus.

The framerate at 2160p was widely doubled to 60 in 2017 and 2018, starting with the [[iPhone 8]], [[Galaxy S9]], [[LG G7]], and [[OnePlus 6]].

Sufficient computing performance of chipsets and image sensor resolution and its reading speeds have enabled mobile [[4320p]] (8K) filming in 2020, introduced with the [[Samsung Galaxy S20]] and [[Redmi K30 Pro]], though some upper resolution levels were foregone (skipped) throughout development, including [[1440p]] (''2.5K''), [[2880p]] (5K), and [[6K resolution|3240p (6K)]], except 1440p on Samsung Galaxy [[#Front_cameras|front cameras]].

;Mid-class
Among mid-range smartphone series, the introduction of higher video resolutions was initially delayed by two to three years compared to flagship counterparts. 720p was widely adapted in 2012, including with the [[Samsung Galaxy S III Mini|Samsung Galaxy S3 Mini]], [[Sony Xperia Go|Sony Xperia go]], and 1080p in 2013 on the [[Samsung Galaxy S4 Mini]] and [[HTC One Mini|HTC One mini]].

The proliferation of video resolutions beyond 1080p has been postponed by several years. The mid-class [[Sony Xperia M5]] supported 2160p filming in 2016, whereas Samsung's mid-class series such as the [[Samsung Galaxy J series|Galaxy J]] and [[Samsung Galaxy A series|A series]] were strictly limited to 1080p in resolution and 30 frames per second at any resolution for six years until around 2019, whether and how much for technical reasons is unclear.

;Setting
A lower video resolution setting may be desirable to extend recording time by reducing space storage and power consumption.

The camera software of some smartphones is equipped with separate controls for resolution, [[frame rate]], and [[bit rate]]. An example of a smartphone with these controls is the [[LG V10]].<ref>{{cite web |last1=La |first1=Lynn |title=The dual-display LG V10 offers ultimate camera and video control (review) |url=https://www.cnet.com/reviews/lg-v10-review/ |website=CNET |language=en}}</ref>

====Slow motion video====
A distinction between different camera software is the method used to store high frame rate video footage, with more recent phones{{efn|For example, Samsung starting with the [[Galaxy S6]]}} retaining both the image sensor's original output frame rate and audio, while earlier phones do not record audio and stretch the video so it can be played back slowly at default speed.

While the stretched encoding method used on earlier phones enables slow motion playback on [[Media player software|video player software]] that lacks manual playback speed control, typically found on older devices, if the aim were to achieve a slow motion effect, the real-time method used by more recent phones offers greater versatility for video editing, where slowed down portions of the footage can be freely selected by the user, and exported into a separate video. A rudimentary video editing software for this purpose is usually pre-installed. The video can optionally be played back at normal (real-time) speed, acting as usual video.

;Development
The earliest smartphone known to feature a slow motion mode is the 2009 [[Samsung i8000 Omnia II]], which can record at QVGA (320×240) at 120 fps ([[Frame rate|frames per second]]). Slow motion is not available on the [[Samsung Galaxy S (2010 smartphone)|Galaxy S1]], [[Samsung Galaxy S II|Galaxy S2]], [[Samsung Galaxy Note (original)|Galaxy Note 1]], and [[Samsung Galaxy S III|Galaxy S3]] flagships.

In early 2012, the [[HTC One X]] allowed 768×432 pixel slow motion filming at an undocumented frame rate. The output footage has been measured as a third of real-time speed.<ref>{{cite web |title=HTC One X review: eXtra special |url=https://www.gsmarena.com/htc_one_x-review-747p6.php |website=GSMArena.com |date=2012-04-12}}</ref>

In late 2012, the [[Samsung Galaxy Note II|Galaxy Note 2]] brought back slow motion, with D1 (720 × 480) at 120 fps. In early 2013, the [[Galaxy S4]] and [[HTC One M7]] recorded at that frame rate with 800 × 450, followed by the [[Samsung Galaxy Note 3|Note 3]] and [[iPhone 5s]] with 720p (1280 × 720) in late 2013, the latter of which retaines audio and original sensor frame rate, as with all later iPhones. In early 2014, the [[Sony Xperia Z2]] and [[HTC One M8]] adapted this resolution as well. In late 2014, the [[iPhone 6]] doubled the frame rate to 240 fps, and in late 2015, the [[iPhone 6s]] added support for 1080p (1920 × 1080) at 120 frames per second. In early 2015, the [[Samsung Galaxy S6|Galaxy S6]] became the first Samsung mobile phone to retain the sensor framerate and audio, and in early 2016, the [[Samsung Galaxy S7|Galaxy S7]] became the first Samsung mobile phone with 240 fps recording, also at 720p.

In early 2015, the ''MT6795'' chipset by [[MediaTek]] promised 1080p@480 fps video recording. The project's status remains indefinite.<ref>{{cite web |title=MediaTek shows off 480fps super slow-motion 1080p video recording on the MT6795 |url=https://www.neowin.net/news/mediatek-shows-off-480fps-super-slow-motion-1080p-video-recording-on-the-mt6795/ |website=Neowin |language=en |date=2015-02-17}}</ref>

Since early 2017, starting with the [[Sony Xperia XZ]], smartphones have been released with a slow motion mode that unsustainably records at framerates multiple times as high, by temporarily storing frames on the image sensor's internal burst memory. Such a recording lasts a few real-time seconds at most.

In late 2017, the [[iPhone 8]] brought 1080p at 240 fps, as well as 2160p at 60 fps, followed by the Galaxy S9 in early 2018. In mid-2018, the [[OnePlus 6]] brought 720p at 480 fps, sustainable for one minute.

In early 2021, the [[OnePlus 9 Pro]] became the first phone with 2160p at 120 fps.

====HDR video====
The first smartphones to record [[HDR video]] were the early 2013 [[Sony Xperia Z]] and mid-2013 [[Sony Xperia Z Ultra|Xperia Z Ultra]], followed by the early 2014 [[Samsung Galaxy S5|Galaxy S5]], all at 1080p.

====Audio recording====
Mobile phones with multiple [[microphone]]s usually allow video recording with [[stereo audio]] for spaciality, with Samsung, Sony, and HTC initially implementing it in 2012 on their [[Samsung Galaxy S3]], [[Sony Xperia S]], and [[HTC One X]].<ref name="761p9"/><ref>{{cite web |title=Sony Xperia S review: NXT of kin |url=https://www.gsmarena.com/sony_xperia_s-review-741p6.php |website=GSMArena.com |page=6}}</ref><ref>{{Cite web|title=HTC One X review: eXtra special|url=https://www.gsmarena.com/htc_one_x-review-747.php|access-date=2021-04-02|website=GSMArena.com|language=en-US}}</ref> Apple implemented stereo audio starting with the 2018 [[iPhone Xs]] family and [[iPhone XR]].<ref>{{cite web |title=Apple iPhone XS review |url=https://www.gsmarena.com/apple_iphone_xs-review-1827p7.php |website=GSMArena.com |page=7}}</ref>

====Front cameras====
=====Photo=====
Emphasis is being put on the front camera since the mid-2010s, where front cameras have reached resolutions as high as typical rear cameras, such as the 2015 [[LG G4]] (8 megapixels), [[Sony Xperia C5 Ultra]] (13 megapixels), and 2016 [[Sony Xperia XA Ultra]] (16 megapixels, optically stabilized). The 2015 [[LG V10]] brought a dual front camera system where the second has a wider angle for group photography. Samsung implemented a front-camera sweep panorama (''panorama selfie'') feature since the [[Galaxy Note 4]] to extend the field of view.

=====Video=====
In 2012, the [[Galaxy S3]] and [[iPhone 5]] brought [[720p]] HD front video recording (at 30 fps). In early 2013, the [[Samsung Galaxy S4]], [[HTC One M7]] and [[Sony Xperia Z]] brought 1080p Full HD at that framerate, and in late 2014, the [[Galaxy Note 4]] introduced 1440p video recording on the front camera. Apple adapted [[1080p]] front camera video with the late 2016 [[iPhone 7]].

In 2019, smartphones started adapting [[2160p]] 4K video recording on the front camera, six years after rear camera 2160p commenced with the [[Galaxy Note 3]].
