Cameras have become standard features of smartphones. {{As of|2019}} phone cameras are now a highly competitive area of differentiation between models, with advertising campaigns commonly based on a focus on the quality or capabilities of a device's main cameras.

Images are usually saved in the [[JPEG]] file format; some high-end phones since the mid-2010s also have [[Raw image format|RAW]] imaging capability.<ref>{{cite web |title=How to Shoot Photos in DNG/RAW on Samsung Galaxy S7 |url=https://www.androidbeat.com/2016/04/how-to-shoot-photos-dng-raw-galaxy-s7/ |website=Android Beat {{!}} Android News, Hacks, Apps, Tips & Reviews Blog |access-date=19 August 2021 |language=en-us |date=24 April 2016 |archive-date=August 19, 2021 |archive-url=https://web.archive.org/web/20210819213752/https://www.androidbeat.com/2016/04/how-to-shoot-photos-dng-raw-galaxy-s7/ |url-status=dead }}</ref><ref>{{cite web |last1=Nikam |first1=Sohil |title=Samsung Dropping RAW Image Support Into Galaxy S6 And S6 Edge Via Android 5.1.1 Update - TechShout |url=https://www.techshout.com/samsung-to-bless-galaxy-s6-and-s6-edge-with-raw-photo-support-via-android-5-1-1-update/ |website=www.techshout.com |access-date=19 August 2021 |date=2015-05-08}}</ref>

====Space constraints====
Typically smartphones have at least one main rear-facing camera and a lower-resolution front-facing camera for "[[selfie]]s" and [[video chat]]. Owing to the limited depth available in smartphones for [[image sensor]]s and [[Lens|optics]], rear-facing cameras are often housed in a "bump" that is thicker than the rest of the phone. Since increasingly thin mobile phones have more abundant horizontal space than the depth that is necessary and used in dedicated cameras for better lenses, there is additionally a trend for phone manufacturers to include multiple cameras, with each optimized for a different purpose ([[Telephoto lens|telephoto]], [[Wide-angle lens|wide angle]], etc.).

Viewed from back, rear cameras are commonly located at the top center or top left corner. A cornered location benefits by not requiring other hardware to be packed around the camera module while increasing [[ergonomy]], as the lens is less likely to be covered when held horizontally.

Modern advanced smartphones have cameras with [[Image stabilization#Optical image stabilization|optical image stabilisation]] (OIS), larger sensors, bright lenses, and even optical zoom plus [[Raw image format|RAW]] images. [[High-dynamic-range imaging|HDR]], "[[Bokeh]] mode" with multi lenses and multi-shot [[Night mode camera|night mode]]s are now also familiar.<ref>{{cite web |title=Top 16 Best Camera Phones For Photography 2019 |url=https://www.ephotozine.com/article/top-16-best-camera-phones-for-photography-2019-23050 |date=April 4, 2019 |archive-url=https://web.archive.org/web/20190512034618/https://www.ephotozine.com/article/top-16-best-camera-phones-for-photography-2019-23050 |archive-date=May 12, 2019}}</ref> Many new smartphone camera features are being enabled via [[computational photography]] [[Digital image processing|image processing]] and multiple specialized lenses rather than larger sensors and lenses, due to the constrained space available inside phones that are being made as slim as possible.

====Dedicated camera button====
Some mobile phones such as the [[Samsung i8000 Omnia 2]], some [[Nokia Lumia]]s and some [[Sony Xperia]]s are equipped with a physical camera shutter button.

Those with two pressure levels resemble the [[point-and-shoot]] intuition of dedicated [[compact camera]]s. The camera button may be used as a [[shortcut (computing)|shortcut]] to quickly and [[ergonomy|ergonomically]] launch the camera software, as it is located more accessibly inside a pocket than the power button.
