Smartphone usage :
In the third quarter of 2012, one billion smartphones were in use worldwide. Global smartphone sales surpassed the sales figures for feature phones in early 2013. As of 2013, 65 percent of U.S. mobile consumers own smartphones. The European mobile device market as of 2013 is 860 million. In China, smartphones represented more than half of all handset shipments in the second quarter of 2012 and in 2014 there were 519.7 million smartphone users, with the number estimated to grow to 700 million by 2018.
As of November 2011, 27% of all photographs were taken with camera-equipped smartphones. A study conducted in September 2012 concluded that 4 out of 5 smartphone owners use the device to shop. Another study conducted in June 2013 concluded that 56% of American adults now owned a smartphone of some kind. Android and iPhone owners account for half of the cell phone user population. Higher income adults and those under age 35 lead the way when it comes to smartphone ownership.
Worldwide shipments of smartphones topped 1 billion units in 2013, up 38% from 2012's 725 million, while comprising a 55% share of the mobile phone market in 2013, up from 42% in 2012.
Since 1996 smartphone shipments have had positive growth, but in Q1 2016 for the first time the shipments dropped by 3 percent year on year. The situation was caused by mature China market.

Issues :
Smartphones have presented issues similar to those affecting other mobile telephones. As well, there are some issues which are unique to smartphones.
Battery life :
Compared to earlier non-smartphones, smartphone battery life has generally been poor and a significant drain on customer satisfaction. There is also a trend to batteries that the user cannot replace.

A 2012 University of Southern California study found that unprotected adolescent sexual activity was more common among owners of smartphones. A study conducted by the Rensselaer Polytechnic Institute's (RPI) Lighting Research Center (LRC) concluded that smartphones, or any backlit devices, can seriously affect sleep cycles. Some persons might become psychologically attached to cellphones resulting in anxiety when separated from the devices.
A "smombie" (a combination of "smartphone" and "zombie") is a walking person using a smartphone and not paying attention as they walk, possibly risking an accident in the process, an increasing social phenomenon. The issue of slow-moving smartphone users led to the temporary creation of a "mobile lane" for walking in Chongqing, China. The issue of distracted smartphone users led the city of Augsburg, Germany to embed pedestrian traffic lights in the pavement.

Main article: Texting while driving
Mobile phone use while driving, including talking on the phone, texting, or operating other phone features, is common but controversial. It is widely considered dangerous due to distracted driving. Being distracted while operating a motor vehicle has been shown to increase the risk of accidents. In September 2010, the US National Highway Traffic Safety Administration(NHTSA) reported that 995 people were killed by drivers distracted by cell phones. In March 2011 a US insurance company,State Farm Insurance, announced the results of a study which showed 19% of drivers surveyed accessed the Internet on a smart phone while driving.Many jurisdictions prohibit the use of mobile phones while driving. In Egypt, Israel, Japan, Portugal and Singapore, both handheld and hands-free use of a mobile phone (which uses a speakerphone) is banned. In other countries including the UK and France and in many U.S. states, only handheld phone use is banned, while hands-free use is permitted.
A 2011 study reported that over 90% of college students surveyed text (initiate, reply or read) while driving. The scientific literature on the dangers of driving while sending a text message from a mobile phone, or texting while driving, is limited. A simulation study at the University of Utah found a sixfold increase in distraction-related accidents when texting.
Due to the increasing complexity of smartphones, this has introduced additional difficulties for law enforcement officials when attempting to distinguish one usage from another in drivers using their devices. 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 mobile phone is being used simply by looking at the driver. This can lead to drivers being stopped for using their device illegally for a phone 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 2010 study reviewed the incidence of mobile phone use while cycling and its effects on behaviour and safety. In 2013 a national survey in the US reported the number of drivers who reported using their cellphones to access the Internet while driving had risen to nearly one of four. A study conducted by the University of Illinois examined approaches for reducing inappropriate and problematic use of mobile phones, such as using mobile phones while driving.
Accidents involving a driver being distracted by talking on a mobile phone have begun to be prosecuted as negligence similar to speeding. In the United Kingdom, from 27 February 2007, motorists who are caught using a hand-held mobile phone while driving will have three penalty points added to their license in addition to the fine of £60. This increase was introduced to try to stem the increase in drivers ignoring the law. Japan prohibits all mobile phone use while driving, including use of hands-free devices. New Zealand has banned hand held cellphone use since 1 November 2009. Many states in the United States have banned texting on cell phones while driving. Illinois became the 17th American state to enforce this law. As of July 2010, 30 states had banned texting while driving, with Kentucky becoming the most recent addition on July 15.
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 communication devices while driving for all 50 states and the District of Columbia between 1992, when first law was passed, through December 1, 2010. The dataset contains information on 22 dichotomous, continuous or categorical variables including, for example, activities regulated (e.g., texting versus talking, hands-free versus handheld), targeted populations, and exemptions.

A "patent war" between Samsung and Apple started when the latter claimed that the original Galaxy S Android phone copied the interface—and possibly the hardware—of Apple's iOS for the iPhone 3GS.

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. Often malware is hidden in pirated versions of legitimate apps, which are then distributed through third-party app stores. Malware risk also comes from what's known as an "update attack", where a legitimate application is later changed to include a malware component, which users then install when they are notified that the app has been updated.
One out of three robberies in 2012 in the United States involved the theft of a mobile phone. An online petition has urged smartphone makers to install kill switchesin their devices. In 2014, Apple's "Find my iPhone" and Google's "Android Device Manager" can disable phones that have been lost/stolen. With BlackBerry Protect in OS version 10.3.2, devices can be rendered unrecoverable to even BlackBerry's own Operating System recovery tools if incorrectly authenticated or dissociated from their account.
Sleep :
Main article: Electronic media and sleep
Using smartphones late at night can disturb sleep, due to the brightly lit screen affecting melatonin levels and sleep cycles. In an effort to alleviate these issues, several apps that 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 have been developed for Android, while iOS 9.3 integrated similar, system-level functionality known as "Night Shift". It has also been theorized that for some users, addicted use of their phones, especially before they go to bed, can result in "ego depletion".
Other terms :
"Phablet", a portmanteau of the words phone and tablet, describes smartphones with larger screens.
"Superphone" is also used by some companies to market phones with unusually large screens and other expensive features.
