==== LTE-A (LTE+) variant GT-i9506 ====
On 24 June 2013, a variant supporting [[Engineering:LTE Advanced|LTE Advanced]] (model number GT-i950'''6'''), the first commercially available device to do so, was announced for South Korea.<ref name="s4ltea">{{cite news|title=SK Telecom doubles down on LTE|url=http://koreajoongangdaily.joinsmsn.com/news/article/article.aspx?aid=2969983|archive-url=https://archive.today/20130628042738/http://koreajoongangdaily.joinsmsn.com/news/article/article.aspx?aid=2969983|url-status=usurped|archive-date=June 28, 2013|access-date=26 June 2013|newspaper=Korea Joongang Daily}}</ref>
In December 2013, it was also shipped to Germany as ''Samsung Galaxy S4 LTE+''<!-- misnomer: Samsung Galaxy S4+ -->, but only with Telekom and [[Company:Vodafone|Vodafone]] branding.<ref name=ltea-de>{{Cite web|url=https://www.connect.de/news/samsung-galaxy-s4-lte-kommt-nach-deutschland-1551975.html|title=Samsung Galaxy S4 LTE+ Alle Infos, Marktstart und Preise|first=Arnulf|last=Schäfer|website=connect|access-date=2019-09-03|archive-date=2019-09-03|archive-url=https://web.archive.org/web/20190903204944/https://www.connect.de/news/samsung-galaxy-s4-lte-kommt-nach-deutschland-1551975.html|url-status=dead}}</ref>
It also was equipped with increased processing power by using the same CPU (Snapdragon 800) and GPU (Adreno 330) hardware as the Galaxy Note 3 ''SM-N9005'',<ref name="s4ltea" /> although no precluded <!--but technically possible using modifications: https://forum.xda-developers.com/showthread.php?t=2711239 --> video recording capabilities beyond 1080p at 30fps.

==== Storage options ====
The S4 comes with either 16&nbsp;GB, 32&nbsp;GB, 64&nbsp;GB of internal storage, which can be supplemented with up to an additional 64&nbsp;GB with a [[Engineering:MicroSD|microSD]] card slot.<ref>{{cite news |url=http://www.pcpro.co.uk/news/380194/samsung-galaxy-s4-price-specs-release-date-revealed |title=Samsung Galaxy S4 price, specs, release date revealed |last=Collins |first=Barry |date=12 April 2013 |work=PC Pro  |access-date=19 April 2013}}</ref> Unofficially, the S4 microSD card slot supports 128&nbsp;GB cards as well.<ref>{{Cite web|url=http://www.cultofandroid.com/64581/android-device-microsd-card-compatibility/|title=Your Android phone supports up to 128&nbsp;GB microSD card|date=2014-07-01|language=en-US|access-date=2016-08-10}}</ref>  The S4 contains a 2600&nbsp;mAh, [[Near-field communication|NFC]]-enabled battery.<ref name=gsmarena-review />

===Software===
{{Further|Software:Android (operating system)|Software:TouchWiz|Software:S Voice}}

The S4 used to have Android 4.2.2 and Samsung's [[Software:TouchWiz|TouchWiz Nature]] user experience. [[Eye tracking|Head tracking]] features have been extended on the S4; the new "Smart Scroll" feature can be used to scroll while looking at the screen by slightly tilting head or phone forward or backward,<ref>{{cite web|url=http://www.samsung.com/us/support/SupportOwnersFAQPopup.do?faq_id=FAQ00053081&fm_seq=62452 |title=What is the Smart Scroll™ feature on my Samsung Galaxy S® 4? |publisher=Samsung.com |date= |accessdate=2014-08-07}}</ref> and "Smart Pause" allows the video player to pause videos if the user is not looking at the screen. "Air View" and "Air Gestures" implement gestures and other functionality (such as previewing images or messages) by holding or swiping a hand or finger slightly above the screen, similarly to Samsung's Galaxy Note series, and adds a feature known as "Quick Glance", which uses the proximity sensor to wake the phone so it can display notifications. The "Group Play" feature allows ad hoc sharing of files between Galaxy phones, along with multiplayer games and music streaming between S4 phones. The S4 also introduces [[Software:Samsung Knox|Knox]] in the Android 4.3 update, a suite of features which implements a [[Sandbox (computer security)|sandbox]] for enterprise environments that can co-exist with a user's "personal" data. Knox incorporates use of the ARM TrustZone extensions and security enhancements to the Android platform.<ref name=engadget-knoxoverview>{{cite web|title=Samsung announces SAFE with Knox, details plans to secure the enterprise Galaxy (hands-on)|url=http://www.engadget.com/2013/02/25/samsung-safe-with-knox/|work=Engadget|date=25 February 2013 |accessdate=18 September 2013}}</ref>

The camera app implements numerous new features (some of which were first seen on the [[Engineering:Samsung Galaxy Camera|Galaxy Camera]]), including an updated interface, and new modes such as "Drama" (which composes a moving element from multiple shots into a single photo), "Eraser" (which takes multiple shots and allows the user to remove unnecessary elements from a picture), "Dual Shot" (which uses the front-facing camera for a [[Engineering:Picture-in-picture|picture-in-picture]] effect), "Sound and Shot" (which allows the user to record a voice clip alongside a photo), "Animated Photo", and "Story Album" among others. The S4 also supports [[High Efficiency Video Coding]] (HEVC), a next-generation [[Video codec|video codec]].<ref name="AndroidcentralSamsungGalaxyS4specs" /><ref name="TechradarSamsungGalaxyS4specs" /><ref>{{cite news |url=http://www.pcworld.idg.com.au/article/456443/samsung_galaxy_s4_has_next-gen_video_codec/ |title=Samsung's Galaxy S4 has a next-gen video codec |last=Simpson |first=Campbell |date=15 March 2013 |work=PCWorld |publisher=IDG |accessdate=15 March 2013}}</ref> Other new pre-loaded apps include WatchOn (an [[Engineering:Electronic program guide|electronic program guide]] that can utilize the S4's infrared transmitter to be a [[Engineering:Remote control|remote control]]), S Translator, the workout tracker S Health, [[Software:S Voice|S Voice]] Drive, S Memo, [[Company:TripAdvisor|TripAdvisor]], and an [[Optical character recognition|optical character recognition]] app.<ref>{{cite web |url=http://reviews.cnet.com/samsung-galaxy-s4/ |title=Samsung Galaxy S4 keeps calm, carries on with big screen, 8-core chip and, yes, eye tracking |last=Dolcourt |first=Jessica |date=14 March 2003 |work=CNET |publisher=CBS Interactive |accessdate=19 April 2013}}</ref> The previous "Hub" apps from past Samsung devices were replaced by a single Samsung Hub app, with access to music, e-books, and games that can be purchased by users.<ref name=gsmarena-review/> To take the screenshot you can simply swipe your hand on the screen from one end to other horizontally.<ref>{{cite web |url=http://www.spinfold.com/take-screenshot-in-samsung-galaxy-s5/|title=Screenshot in Galaxy series|date=28 October 2014 }}</ref>

In February 2014, Samsung began rolling out an update to [[Software:Android KitKat|Android 4.4.2 "KitKat"]] for the S4; the update adds user interface tweaks such as a camera shortcut on the corner of the lock screen, options for setting default launcher and text messaging applications, support for printing, and a new location settings menu for tracking and controlling the use of location tracking by apps.<ref name=zdnet-s4kitkat>{{cite web|title=KitKat rolls out for Galaxy S4, Note 3 in UK and US|url=http://www.zdnet.com/kitkat-rolls-out-for-galaxy-s4-note-3-in-uk-and-us-7000027243/|work=ZDNet|publisher=CBS Interactive|access-date=28 March 2014}}</ref><ref name=gsmarena-44s4>{{cite web|title=Android 4.4 KitKat now seeding to Korean Galaxy S4 LTE-A|url=http://www.gsmarena.com/android_44_kitkat_now_seeding_on_korean_galaxy_s4_ltea-news-7754.php |work=GSMArena|access-date=28 March 2014}}</ref><ref name=pl-kitkat>{{cite web|title=What's new in the Samsung Galaxy Note 3 and Galaxy S4 Android 4.4.2 KitKat update?|url=http://www.pocket-lint.com/news/127845-what-s-new-in-the-samsung-galaxy-note-3-and-galaxy-s4-android-4-4-2-kitkat-update|work=Pocket-lint|access-date=28 March 2014}}</ref> It also makes significant changes to the handling of secondary storage on the device for security reasons; applications' access to the SD card is restricted to designated, app-specific directories only, while full access to internal primary storage is still allowed. Although this behavior has existed since Android 3.0 "Honeycomb", OEMs such as Samsung previously modified their distributions of Android to retain the previous behavior, allowing applications to have unlimited access to SD card contents.<ref name=anandtech-sdkitkat>{{cite web|last=Ho|first=Joshua|title=Examining MicroSD changes in Android 4.4 |url= http://www.anandtech.com/show/7859/examining-microsd-changes-in-android-44 |work=Anandtech |access-date=28 March 2014}}</ref>

In January 2015, Samsung began rolling out an update to Android [[Software:Android Lollipop|5.0.1 "Lollipop"]] in Russia and India, an update which brings all the features of Lollipop, such as enhanced performance and lockscreen, including a refined interface with a flatter and geometric look, as seen on the Galaxy S5.<ref>{{cite web|url=http://www.sammobile.com/2015/01/30/samsung-galaxy-s4-gt-i9500-is-getting-the-lollipop-update-in-russia/|title=[Updated] Samsung Galaxy S4 (GT-I9500) is getting the Lollipop update in Russia|author=SamMobile|work=SamMobile|date=30 January 2015 }}</ref> Samsung paused the rollout soon after, when users reported major bugs.

=== Model variants ===
Several different model variants of the S4 are sold, with most variants varying mainly in handling regional network types and bands. To prevent [[Social:Grey market|grey market]] reselling, models of the S4 manufactured after July 2013 implement a [[Social:Regional lockout|regional lockout]] system in certain regions, requiring that the first [[SIM card]] used on a European and North American model be from a carrier in that region. Samsung stated that the lock would be removed once a local SIM card is used.<ref name=verge-samsunglock>{{cite web |title=Samsung region locking the Note 3 to keep out resellers |url= https://www.theverge.com/2013/9/26/4772820/samsung-region-locks-european-galaxy-note-3-within-europe |work=The Verge |date= 26 September 2013 |access-date=30 September 2013}}</ref> SIM format for all variants is Micro-SIM, which can have one or two depending on model.

[[File:Samsung Galaxy S4 with black cover.jpg|thumb|right|The "S-View Cover" accessory contains a window that can be used to display notifications and a clock]]

At retail, the S4 is bundled with a [[Engineering:USB|USB]] cable, AC adapter, and in-ear headphones.<ref name=gsmarena-review /> The "S-View Cover" accessory "closes" the phone.

== Reception ==

=== Critical reception ===

While some users considered all new Galaxy S4 features innovative and legitimately useful, others called them [[Feature creep|feature creep]]<ref>{{Citation|title=Feature creep plagues Samsung's new Galaxy S4|url=http://www.nbcnews.com/video/nbcnews.com/51634787#51634787|access-date=2016-12-05}}</ref> or just [[Social:Gimmick|gimmick]]s.<ref>{{Cite news|url=http://www.techradar.com/news/phone-and-communications/mobile-phones/gimmick-watch-which-galaxy-s4-features-are-actually-useful-1137782|title=Gimmick watch: which Galaxy S4 features are actually useful?|newspaper=TechRadar|language=en}}</ref> Those features are, for example, ''Smart Pause'', ''Smart Rotation'', ''Smart Scroll'', ''Air View'', ''Air Gesture'', ''Story Album'' and ''Temperature and humidity sensors''. These features and sensors are available and optionally utilizable for users and software that needs them.<br />Additionally, the Galaxy S4 is equipped with an ''"easy mode"'' that hides many features and increases the size of on-screen elements for easier readability for novice mobile phone users.<ref name=easy>{{Cite web|url=https://www.samsung.com/ca/support/mobile-devices/galaxy-s4-easy-mode/|title=Galaxy S4: Easy Mode|website=Samsung ca}}</ref><ref name=talkandroid_easymode>{{Cite web|url=https://www.talkandroid.com/guides/samsung-galaxy-s-4-guides/for-the-beginner-how-to-set-the-galaxy-s-4-to-easy-mode/|title=For the beginner: How to set the Galaxy S 4 to Easy Mode|date=8 May 2017 }}</ref><ref name=digitin_easymode>{{Cite web|url=https://www.digit.in/features/mobile-phones/understanding-easy-mode-on-the-samsung-galaxy-s4-14698.html|title=Understanding Easy Mode on the Samsung Galaxy S4 &#124; Digit|first=Vishal|last=Mathur|date=January 30, 2018|website=digit.in}}</ref>

The S4 received many positive reviews, though some criticism. [[Company:Gigaom|Gigaom]]'s Tofel says he would recommend the S4 "without hesitation" and says that it's "Samsung's defining phone".<ref>{{cite web |url=http://gigaom.com/2013/04/23/samsung-galaxy-s-4-review/ |title=Samsung Galaxy S 4 reviewed: Too many features or just right? |last=Tofel |first=Kevin C. |date=23 April 2013 |publisher=GigaOM |access-date=14 June 2013}}</ref> ReadWrite's Rowinski described the phone as a "solid" and "first-rate smartphone", but criticised Samsung's use of "bloatware, pre-loaded apps and features that you will likely never use".<ref>{{cite web |url=http://readwrite.com/2013/04/23/samsung-galaxy-s4-more-less-review |title=Samsung Galaxy S4: Sometimes, More Is Less [Review&#93; |last=Rowiski |first=Dan |date=23 April 2013 |work=ReadWrite |publisher=[[Company:SAY Media|SAY Media]] |access-date=14 June 2013}}</ref> ''TIME'''s McCraken says the S4 is a smartphone with everything; it has the biggest screen and the most built-in features. He wishes the S4 would mark the end of Samsung's plan to add too many new features with its flagship smartphones.<ref>{{cite magazine |url=http://techland.time.com/2013/04/24/samsung-galaxy-s4-review/ |title=Samsung Galaxy S 4 Review: Gimme One Smartphone, with Everything |last=McCracken |first=Harry |date=24 April 2013 |magazine={{wipe|Time (magazine)}}  |access-date=14 June 2013}}</ref>

Technology journalist Walt Mossberg described the S4 as "a good phone, just not a great one". Mossberg wrote: "while I admire some of its features, overall, it isn't a game-changer." He criticized the software as "especially weak" and "often gimmicky, duplicative of standard Android apps, or, in some cases, only intermittently functional." He urged readers to "consider the more polished-looking, and quite capable, HTC One, rather than defaulting to the latest Samsung."<ref>{{cite web |url=http://allthingsd.com/20130423/galaxy-s-4-is-a-good-but-not-a-great-step-up |title=Galaxy S 4 Is a Good, but Not a Great, Step Up |last=Mossberg |first=Walt |date=23 April 2013 |publisher=AllThingsD}}</ref>

''Consumer Reports'' named the S4 as the top smartphone as of May 2013 due to its screen quality, multitasking support, and built-in IR blaster.<ref>{{cite news |url=http://www.cnn.com/2013/05/20/tech/mobile/galaxy-s4-top-smartphone |title=Samsung Galaxy S4 named top smartphone by Consumer Reports |last=Kelly |first=Heather |date=21 May 2013 |work=CNN Tech |publisher=CNN |access-date=14 June 2013}}</ref>

Critics noted that about half of the internal storage on the S4's 16&nbsp;GB model was taken up by its system software, using 1&nbsp;GB more than the S III and leaving only 8.5 to 9.15&nbsp;GB for the storage of other data, including downloaded apps (some of which cannot be moved to the SD card). Samsung initially stated that the space was required for the S4's new features, but following a report regarding the issue on the BBC series ''Watchdog'', Samsung stated that it would review the possibility of optimising the S4's operating system to use less local drive space in a future update.<ref>{{cite web |url=http://crave.cnet.co.uk/mobiles/samsung-defends-16gb-s4s-mere-8gb-of-usable-storage-50011111/ |title=Samsung defends 16&nbsp;GB S4's mere 8&nbsp;GB of usable storage |last=Westaway |first=Luke |date=2 May 2013 |work=CNET UK |publisher=CBS Interactive |access-date=19 May 2013}}</ref><ref>{{cite web |url=http://www.techradar.com/news/phone-and-communications/mobile-phones/samsung-promises-to-review-galaxy-s4-storage-space-after-watchdog-expos--1151872 |title=Samsung promises to review Galaxy S4 storage space after Watchdog exposé |last=Solomon |first=Kate |date=16 May 2013 |work=[[TechRadar]] |publisher=Future plc |access-date=19 May 2013}}</ref><ref>{{cite web |url=http://www.pcadvisor.co.uk/news/mobile-phone/3444658/samsung-galaxy-s4-storage-woes/ |title=Samsung Galaxy S4 suffers from storage woes |last=Martin |first=Chris |date=29 April 2013 |work=PC Advisor |publisher=IDG |access-date=20 May 2013}}</ref> Storage optimizations were brought in an update first released in June 2013, which frees 80&nbsp;MB of internal storage and restores the ability to move apps to the device's microSD card.<ref>{{cite web |url=https://www.theverge.com/2013/6/6/4401652/samsung-galaxy-s4-update-storage-improvements-sd-card-apps |title=Samsung Galaxy S4 update addresses storage complaints with move to SD card feature |last=Souppouris |first=Aaron |date=6 June 2013 |work=[[The Verge]] |publisher=[[Company:Vox Media|Vox Media]] |access-date=6 June 2013}}</ref>

On December 2, 2013, Canadian Richard Wygand uploaded a YouTube video describing his phone combusting.<ref>{{cite web|last=Wygand|first=Richard|title=samsung galaxy s4 caught fire proof for samsung|website=[[Company:YouTube|YouTube]] |url=https://www.youtube.com/watch?v=dc4duKuPrQ0|access-date=13 December 2013}}{{unreliable source?|date=January 2014}}</ref> The phone was plugged into AC power overnight; he woke up to the smell of smoke and burning matter. In the video, the power cord was shown to be severely burnt and showed warped damage to the power plug. Later in the video, Wygand describes how he attempted to get a replacement:
{{blockquote|We have a service provider; it's Rogers here in Canada. Rogers [has] seen it, and they freaked out. They even said, 'You could send it in through us — it'll take three weeks — or just go see Samsung.' The Samsung reps just said that they need video proof, and now we have to call it in.

In his second video, uploaded a few days after the first one, Wygand states that in order to receive a replacement phone, Samsung allegedly asked him to sign a legal document requiring him to [[Philosophy:Streisand effect|remove the video]], remain silent about the agreement, and surrender any future claims against the company.<ref>{{cite web|last=Wygand|first=Richard|title=et tu, samsung?

In an interview with Mashable, Wygand said that since he posted the second video, no further response from Samsung was received. However, an official spokesman from Samsung told Mashable, "Samsung takes the safety and security of our customers very seriously. Our Samsung Canada team is in touch with the customer, and is investigating the issue."<ref>{{cite web|last=Strange|first=Adario|title=Galaxy S4 Customer Posts Defective Phone Video, Samsung Demands Removal|date=11 December 2013 |url=http://mashable.com/2013/12/10/samsung-s4-burns-up-user-posts-video-samsung-ask-him-to-remove-it/|publisher=Mashable|access-date=13 December 2013}}</ref>

In the UK, companies which sold the S4 have varied in their reactions to claims by worried customers for replacement batteries under the Sale of Goods Act. Amazon, for example, have simply refunded part of the purchase price to allow for the cost of a replacement battery. O2 however insist that the complete phone, with the faulty battery, be returned to them so that they in turn can send it to [[Company:Samsung|Samsung]] to consider the claim.
