In camera phones outsold stand-alone digital cameras, and in they outsold film and digital stand-alone cameras. Five billion camera phones were sold in five years, and by more than half of the installed base of all mobile phones were camera phones.
Sales of separate cameras peaked in Many early smartphones didn't 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.
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 image manipulation , and abilities to directly share photos through the use of apps and web-based services.
In , digital camera sales were 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 focus shot.
In the Nokia N95 was notable as a smartphone that had a 5. Some specialized feature phones like the LG Viewty , Samsung SGH-G , and Sony Ericsson Ki , all released later that year, also had 5.
By 5. In the Samsung Omnia HD was the first phone with p video recording. A megapixel smartphone with 3x optical zoom was announced in late In 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. The Nokia 9 PureView was released in featuring a penta-lens camera system.
In the early s, larger smartphones with screen sizes of at least millimetres 5. Some companies began to release smartphones in incorporating flexible displays to create curved form factors, such as the Samsung Galaxy Round and LG G Flex.
By , p displays began to appear on high-end smartphones. New trends for smartphone displays began to emerge in , with both LG and Samsung releasing flagship smartphones LG G6 and Galaxy S8 , utilizing displays with taller aspect ratios than the common ratio, and a high screen-to-body ratio, also known as a "bezel-less design".
These designs allow the display to have a larger diagonal measurement, but with a slimmer width than displays with an equivalent screen size.
Another trend popularized in were displays containing tab-like cut-outs at the top-centre—colloquially known as a "notch"—to contain the front-facing camera, and sometimes other sensors typically located along the top bezel of a device.
This design characteristic appeared almost simultaneously on the Sharp Aquos S2 and the Essential Phone ,  which featured circular tabs for their cameras, followed just a month later by the iPhone X , which used a wider tab to contain a camera and facial scanning system known as Face ID.
Other variations of the practice later emerged, such as a "hole-punch" camera such as those of the Honor View 20, and Samsung's Galaxy A8s and Galaxy S10 —eschewing the tabbed "notch" for a circular or rounded-rectangular cut-out within the screen instead,  while Oppo released the first "all-screen" phones with no notches at all,  including one with a mechanical front camera that pops up from the top of the device Find X ,  and a prototype for a front-facing camera that can be embedded and hidden below the display, using a special partially-translucent screen structure that allows light to reach the image sensor below the panel.
Devices with a high refresh rate have lower motion blur and input lag. Smartphones utilizing flexible displays were theorized as possible once manufacturing costs and production processes were feasible.
Also that month, Samsung presented a prototype phone featuring an "Infinity Flex Display" at its developers conference, with a smaller, outer display on its "cover", and a larger, tablet-sized display when opened.
Samsung stated that it also had to develop a new polymer material to coat the display as opposed to glass. The first smartphone with a fingerprint reader was the Motorola Atrix 4G in One of the barriers of fingerprint reading amongst consumers was security concerns, however Apple was able to address these concerns by encrypting this fingerprint data onto the A7 Processor located inside the phone as well as make sure this information could not be accessed by third-party applications and is not stored in iCloud or Apple servers .
In , Samsung introduced the Galaxy S3 GT-i with retrofittable wireless charging , pop-up video playback, 4G - LTE variant GT-i quad-core processor.
In , Fairphone launched its first "socially ethical" smartphone at the London Design Festival to address concerns regarding the sourcing of materials in the manufacturing  followed by Shiftphone in In October , Motorola Mobility announced Project Ara , a concept for a modular smartphone platform that would allow users to customize and upgrade their phones with add-on modules that attached magnetically to a frame.
Microsoft, expanding upon the concept of Motorola's short-lived "Webtop", unveiled functionality for its Windows 10 operating system for phones that allows supported devices to be docked for use with a PC-styled desktop environment.
Samsung and LG used to be the "last standing" manufacturers to offer flagship devices with user-replaceable batteries. But in , Samsung succumbed to the minimalism trend set by Apple, introducing the Galaxy S6 without a user-replaceable battery.
In addition, Samsung was criticised for pruning long-standing features such as MHL , Micro USB 3. Major technologies that began to trend in included a focus on virtual reality and augmented reality experiences catered towards smartphones, the newly introduced USB-C connector, and improving LTE technologies.
In , the first smartphones featuring fingerprint readers embedded within OLED displays were announced, followed in by an implementation using an ultrasonic sensor on the Samsung Galaxy S In , the majority of smartphones released have more than one camera, are waterproof with IP67 and IP68 ratings, and unlock using facial recognition or fingerprint scanners.
A typical smartphone contains a number of metal—oxide—semiconductor MOS integrated circuit IC chips,  which in turn contain billions of tiny MOS field-effect transistors MOSFETs.
Smartphones have central processing units CPUs , similar to those in computers, but optimised to operate in low power environments.
In smartphones, the CPU is typically integrated in a CMOS complementary metal—oxide—semiconductor system-on-a-chip SoC application processor.
The performance of mobile CPU depends not only on the clock rate generally given in multiples of hertz  but also on the memory hierarchy.
Because of these challenges, the performance of mobile phone CPUs is often more appropriately given by scores derived from various standardized tests to measure the real effective performance in commonly used applications.
One of the main characteristics of smartphones is the screen. Depending on the device's design, the screen fills most or nearly all of the space on a device's front surface.
Many smartphone displays have an aspect ratio of , but taller aspect ratios became more common in Screen sizes are measured in diagonal inches.
Phones with screens larger than 5. Smartphones with screens over 4. Due to design advances, some modern smartphones with large screen sizes and "edge-to-edge" designs have compact builds that improve their ergonomics, while the shift to taller aspect ratios have resulted in phones that have larger screen sizes whilst maintaining the ergonomics associated with smaller displays.
Liquid-crystal displays LCDs and organic light-emitting diode OLED displays are the most common. Some displays are integrated with pressure-sensitive digitizers, such as those developed by Wacom and Samsung ,  and Apple's Force Touch system.
The latter was utilized by few phones such as the Samsung Galaxy S4 , Note 3 and Sony Xperia Sola for preview tooltips such as on the video player 's seek bar, in text messages, and quick contacts on the dial pad , lock screen animation, and the simulation of a hovering mouse cursor on web sites.
While eMMC embedded multi media card flash storage was most commonly used in mobile phones, its successor, UFS Universal Flash Storage with higher transfer rates emerged throughout the s for upper-class devices.
Benefits over USB on the go storage and cloud storage include offline availability and privacy , not reserving the charging port , no connection instability or latency , no dependence on voluminous data plans , and preservation of the limited rewriting cycles of the device's permanent internal storage.
In case of technical defects which make the device unusable or un bootable as a result of liquid damage, fall damage, screen damage, bending damage , malware , or bogus system updates ,  etc.
A memory card can usually [a] immediately be re-used in a different memory-card-enabled device with no necessity for prior file transfers.
Some dual-SIM mobile phones are equipped with a hybrid slot, where one of the two slots can be occupied by either a SIM card or a memory card.
Originally, mass storage access was commonly enabled to computers through USB. Over time, mass storage access was removed, leaving the Media Transfer Protocol as protocol for USB file transfer, due to its non-exclusive access ability where the computer is able to access the storage without it being locked away from the mobile phone's software for the duration of the connection, and no necessity for common file system support, as communication is done through an abstraction layer.
However, unlike mass storage, Media Transfer Protocol lacks parallelism, meaning that only a single transfer can run at a time, for which other transfer requests need to wait to finish.
In addition, the direct access of files through MTP is not supported. Any file is wholly downloaded from the device before opened. Some audio quality enhancing features, such as Voice over LTE and HD Voice have appeared and are often available on newer smartphones.
Sound quality can remain a problem due to the design of the phone, the quality of the cellular network and compression algorithms used in long-distance calls.
The small speakers can also be used to listen to digital audio files of music or speech or watch videos with an audio component, without holding the phone close to the ear.
Some mobile phones such as the HTC One M8 and the Sony Xperia Z2 are equipped with stereophonic speakers to create spacial sound when in horizontal orientation.
A smartphone typically uses a lithium-ion battery due to its high energy density. As a result of repeated charging and discharging throughout ordinary usage, batteries chemically wear down, losing both energy capacity and output power, which results in loss of processing speeds followed by system outages.
While such a design had initially been used in most mobile phones, including those with touch screen that were not Apple iPhones , it has largely been usurped throughout the s by permanently built-in, non-replaceable batteries; a design practice criticized for planned obsolescence.
While charging rates have been increasing, with 15 Watts in ,  20 Watts in ,  and 45 Watts in ,  the power throughput may be throttled down significantly during operation of the device.
By the end of , smartphone battery life has become generally adequate;  however, earlier smartphone battery life was poor due to the weak batteries that could not handle the significant power requirements of the smartphones' computer systems and color screens.
Smartphone users purchase additional chargers for use outside the home, at work, and in cars and by buying portable external "battery packs".
External battery packs include generic models which are connected to the smartphone with a cable, and custom-made models that "piggyback" onto a smartphone's case.
In , Samsung had to recall millions of the Galaxy Note 7 smartphones due to an explosive battery issue. Cameras have become standard features of smartphones.
As of 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.
Typically smartphones have at least one main rear-facing camera and a lower-resolution front-facing camera for " selfies " and video chat. Owing to the limited depth available in smartphones for image sensors and optics , rear-facing cameras are often housed in a "bump" that's 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's additionally a trend for phone manufacturers to include multiple cameras, with each optimized for a different purpose telephoto , wide angle , etc.
Images are usually saved in the JPEG file format; some high-end phones also have RAW image capability.
Modern advanced smartphones have cameras with optical image stabilisation OIS , larger sensors, bright lenses, and even optical zoom plus RAW images.
HDR , " Bokeh mode" with multi lenses and multi-shot night modes are now also familiar. A wide range of accessories are sold for smartphones, including cases , memory cards , screen protectors , power charging cables , wireless power stations, USB On-The-Go adapters for connecting USB drives and or, in some cases, a HDMI cable to an external monitor , MHL adapters, add-on batteries, power banks , headphones , combined headphone-microphones which, for example, allow a person to privately conduct calls on the device without holding it to the ear , and Bluetooth -enabled powered speakers that enable users to listen to media from their smartphones wirelessly.
Cases range from relatively inexpensive rubber or soft plastic cases which provide moderate protection from bumps and good protection from scratches to more expensive, heavy-duty cases that combine a rubber padding with a hard outer shell.
Some cases have a "book"-like form, with a cover that the user opens to use the device; when the cover is closed, it protects the screen.
Some "book"-like cases have additional pockets for credit cards, thus enabling people to use them as wallets. Accessories include products sold by the manufacturer of the smartphone and compatible products made by other manufacturers.
A mobile operating system or mobile OS is an operating system for phones, tablets , smartwatches , or other mobile devices. Mobile operating systems combine features of a personal computer operating system with other features useful for mobile or handheld use; usually including, and most of the following considered essential in modern mobile systems; a touchscreen , cellular , Bluetooth , Wi-Fi Protected Access , Wi-Fi , Global Positioning System GPS mobile navigation, video- and single-frame picture cameras , speech recognition , voice recorder , music player , near field communication , and infrared blaster.
By Q1 , over million smartphones were sold with Mobile devices with mobile communications abilities e. Research has shown that these low-level systems may contain a range of security vulnerabilities permitting malicious base stations to gain high levels of control over the mobile device.
A mobile app is a computer program designed to run on a mobile device, such as a smartphone. The term "app" is a short-form of the term "software application".
The introduction of Apple's App Store for the iPhone and iPod Touch in July popularized manufacturer-hosted online distribution for third-party applications software and computer programs focused on a single platform.
There are a huge variety of apps, including video games , music products and business tools. Up until that point, smartphone application distribution depended on third-party sources providing applications for multiple platforms, such as GetJar , Handango , Handmark , and PocketGear.
Following the success of the App Store, other smartphone manufacturers launched application stores, such as Google's Android Market later renamed to the Google Play Store and RIM's BlackBerry App World and Android-related app stores like F-Droid.
Since , smartphone shipments have had positive growth. In , smartphone sales began to decline for the first time. The situation was caused by the maturing China market.
In , Samsung had the highest shipment market share worldwide, followed by Apple. In , Samsung had Only Apple lost market share, although their shipment volume still increased by Samsung's mobile business is half the size of Apple's, by revenue.
Apple business increased very rapidly in the years to In many countries, mobile phones are used to provide mobile banking services, which may include the ability to transfer cash payments by secure SMS text message.
Kenya's M-PESA mobile banking service, for example, allows customers of the mobile phone operator Safaricom to hold cash balances which are recorded on their SIM cards.
Cash can be deposited or withdrawn from M-PESA accounts at Safaricom retail outlets located throughout the country and can be transferred electronically from person to person and used to pay bills to companies.
Branchless banking has been successful in South Africa and the Philippines. A pilot project in Bali was launched in by the International Finance Corporation and an Indonesian bank, Bank Mandiri.
Another application of mobile banking technology is Zidisha , a US-based nonprofit micro-lending platform that allows residents of developing countries to raise small business loans from Web users worldwide.
Zidisha uses mobile banking for loan disbursements and repayments, transferring funds from lenders in the United States to borrowers in rural Africa who have mobile phones and can use the Internet.
Mobile payments were first trialled in Finland in when two Coca-Cola vending machines in Espoo were enabled to work with SMS payments.
Eventually, the idea spread and in , the Philippines launched the country's first commercial mobile payments systems with mobile operators Globe and Smart.
Some mobile phones can make mobile payments via direct mobile billing schemes, or through contactless payments if the phone and the point of sale support near field communication NFC.
Some apps allows for sending and receiving facsimile Fax , over a smartphone, including facsimile data composed of raster bi-level graphics generated directly and digitally from document and image file formats.
The rise in popularity of touchscreen smartphones and mobile apps distributed via app stores along with rapidly advancing network , mobile processor , and storage technologies led to a convergence where separate mobile phones , organizers , and portable media players were replaced by a smartphone as the single device most people carried.
Streaming video services are easily accessed via smartphone apps and can be used in place of watching television.
People have often stopped wearing wristwatches in favor of checking the time on their smartphones, and many use the clock features on their phones in place of alarm clocks.
Additionally, in many lesser technologically developed regions smartphones are people's first and only means of Internet access due to their portability,  with personal computers being relatively uncommon outside of business use.
The cameras on smartphones can be used to photograph documents and send them via email or messaging in place of using fax facsimile machines.
Payment apps and services on smartphones allow people to make less use of wallets, purses, credit and debit cards, and cash. Mobile banking apps can allow people to deposit checks simply by photographing them, eliminating the need to take the physical check to an ATM or teller.
In , University of Southern California study found that unprotected adolescent sexual activity was more common among owners of smartphones.
Mobile phone use while driving—including calling , text messaging , playing media, web browsing , gaming , using mapping apps or operating other phone features—is common but controversial, since it is widely considered dangerous due to what is known as distracted driving.
Being distracted while operating a motor vehicle has been shown to increase the risk of accidents.
In September , the US National Highway Traffic Safety Administration NHTSA reported that people were killed by drivers distracted by phones.
In Egypt, Israel, Japan, Portugal and Singapore, both handheld and hands-free calling on a mobile phone which uses a speakerphone is banned.
In other countries including the UK and France and in many US states, only the use of calling on handheld phones is banned, while hands-free use is permitted.
A simulation study at the University of Utah found a sixfold increase in distraction-related accidents when texting.
This is more apparent in countries which ban both handheld and hands-free usage, rather than those which ban handheld use only, as officials cannot easily tell which function of the phone is being used simply by looking at the driver.
This can lead to drivers being stopped for using their device illegally for a call when, in fact, they were using the device legally, for example, when using the phone's incorporated controls for car stereo, GPS or satnav.
A study reviewed the incidence of phone use while cycling and its effects on behavior and safety. Accidents involving a driver being distracted by being in a call on a phone have begun to be prosecuted as negligence similar to speeding.
New Zealand has banned handheld phone use since 1 November Many states in the United States have banned text messaging on phones while driving.
Illinois became the 17th American state to enforce this law. Public Health Law Research maintains a list of distracted driving laws in the United States.
This database of laws provides a comprehensive view of the provisions of laws that restrict the use of mobile devices while driving for all 50 states and the District of Columbia between , when first law was passed through December 1, The dataset contains information on 22 dichotomous, continuous or categorical variables including, for example, activities regulated e.
There was also smartphone patents licensing and litigation involving Sony Mobile , Google , Apple Inc. The conflict is part of the wider "patent wars" between multinational technology and software corporations.
To secure and increase market share , companies granted a patent can sue to prevent competitors from using the methods the patent covers.
Since the s the number of lawsuits, counter-suits, and trade complaints based on patents and designs in the market for smartphones, and devices based on smartphone OSes such as Android and iOS , has increased significantly.
Initial suits, countersuits, rulings, license agreements, and other major events began in as the smartphone market stated to grow more rapidly by With the rise in number of mobile medical apps in the market place, government regulatory agencies raised concerns on the safety of the use of such applications.
These concerns were transformed into regulation initiatives worldwide with the aim of safeguarding users from untrusted medical advice. Smartphone malware is easily distributed through an insecure app store.
An online petition has urged smartphone makers to install kill switches in their devices. With BlackBerry Protect in OS version Leaked documents published by WikiLeaks , codenamed Vault 7 and dated from to , detail the capabilities of the United States Central Intelligence Agency CIA to perform electronic surveillance and cyber warfare , including the ability to compromise the operating systems of most smartphones including iOS and Android.
Guidelines for mobile device security were issued by NIST  and many other organizations. For conducting a private, in-person meeting, at least one site recommends that the user switch the smartphone off and disconnect the battery.
Using smartphones late at night can disturb sleep, due to the blue light and brightly lit screen, which affects melatonin levels and sleep cycles.
In an effort to alleviate these issues, "Night Mode" functionality to change the color temperature of a screen to a warmer hue based on the time of day to reduce the amount of blue light generated became available through several apps for Android and the f.
It has also been theorized that for some users, addiction to use of their phones, especially before they go to bed, can result in " ego depletion.
In mobile phones released since the second half of the s, operational life span commonly is limited by built-in batteries which are not designed interchangeable.
The life expectancy of batteries depends on usage intensity of the powered device, where activity longer usage and tasks demanding more energy expire the battery earlier.
Lithium-ion and Lithium-polymer batteries, those commonly powering portable electronics , additionally wear down more from fuller charge and deeper discharge cycles, and when unused for an extended amount of time while depleted, where self-discharging may lead to a harmful depth of discharge.
The functional life span of mobile phones may be limited by lack of software update support, such as deprecation of TLS cipher suites by certificate authority with no official patches provided for earlier devices.
