A, secondary microphone and are located at the top. The S4 is widely available in black and white color finishes; in selected regions, Samsung also introduced versions in red, purple, pink, brown with gold trim, and light pink with gold trim. In late-January 2014, Samsung's Russian website briefly listed a new black model with a backing, similar to the. The S4's display is larger than its predecessor, with a 5-inch (130 mm), screen with a resolution of 441, and 3. Unlike previous models, the S4 does not contain support, citing the increased use of online media outlets for content consumption on mobile devices. Galaxy S4 models use one of two processors, depending on the region and network compatibility.
The S4 version for North America, most of Europe, parts of Asia, and other countries contains 's, containing a quad-core 1.9 GHz CPU and an GPU. The chip also contains a modem which supports. Other models include Samsung's system-on-chip with a. The CPU comprises a 1.6 GHz cluster and a 1.2 GHz quad-core cluster. The chip can dynamically switch between the two clusters of cores based on CPU usage; the chip switches to the A15 cores when more processing power is needed, and stays on the A7 cores to conserve energy on lighter loads. Only one of the clusters is used at any particular moment, and software sees the processor as a single quad-core CPU. The SoC also contains an tri-core SGX 544 (GPU).
Regional models of the S4 vary in support for LTE; for Exynos 5-based models, while the E300K/L/S versions support LTE, with the Cortex-A15 also clocked at 1.6 GHz. The GT-I9500 model does not. The S4 GT-I9505 includes a multiband LTE transceiver.

S4 using TouchWiz on 'Jelly Bean' The S4 was originally released with Android 4.2.2 and Samsung's interface. 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, 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 sharing of files between Galaxy phones, along with multiplayer games and music streaming between S4 phones. The S4 also introduces in the Android 4.3 update, a suite of features which implements a for enterprise environments that can co-exist with a user's 'personal' data. Knox incorporates use of the ARM extensions and security enhancements to the Android platform. The camera app implements numerous new features (some of which were first seen on the ), 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 effect), 'Sound and Shot' (which allows the user to record a voice clip alongside a photo), 'Animated Photo', and 'Story Album' among others.

However, Samsung halted the rollout following reports from Galaxy S III users that Samsung's version of 4.3 had caused instability and increased battery usage.
The rollout was resumed in December 2013. In February 2014, Samsung began rolling out an update to 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. 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', such as Samsung previously modified their distributions of Android to retain the previous behavior, allowing applications to have unlimited access to SD card contents. In January 2015, Samsung began rolling out an update to Android 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. Samsung paused the rollout soon after, when users reported major bugs. The rollout continued in March 2015 starting with unlocked models in the UK, Nordic and Baltic countries and has since then spread to several other countries. US (starting with AT&T and Sprint) and Canadian Samsung Galaxy S4 models received Android 5.0.1 Lollipop update in April 2015.

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 reselling, models of the S4 manufactured after July 2013 implement a system in certain regions, requiring that the first 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. SIM format for all variants is Micro-SIM, which can have one or two depending on model. 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 cable,. The 'S-View Cover' accessory 'closes' the phone. When this cover is detected (by a ), the time and battery are displayed in this cover's window area.
Reception Critical reception The S4 received many positive reviews, though some criticism. 's Tofel says he would recommend the S4 'without hesitation' and says that it's 'Samsung's defining phone'. 's Rowinski described the phone as a 'solid' and 'first-rate smartphone', but criticised Samsung's use of ', pre-loaded apps and features that you will likely never use'. '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. Technology journalist 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, rather than defaulting to the latest Samsung.' Named the S4 as the top smartphone as of May 2013 due to its screen quality, multitasking support, and built-in IR blaster. Critics noted that about half of the internal storage on the S4's 16 GB model was taken up by its system software, using 1 GB more than the S III and leaving only 8.5 to 9.15 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 series, 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. Storage optimizations were brought in an update first released in June 2013, which frees 80 MB of internal storage and restores the ability to move apps to the device's microSD card. Commercial reception The S4 reached 10 million pre-orders from retailers in the first two weeks after its announcement.
In the United States, this prompted Samsung to announce that due to larger than expected demand, the roll out of devices on U.S. Carriers Sprint and T-Mobile would be slower than expected.
The S4 sold 4 million in 4 days and 10 million in 27 days making it the then fastest selling smartphone in Samsung's history (this has been eclipsed by the ). The Galaxy S III sold 4 million units in 21 days, the took 55 days and the took 85 days. Samsung shipped more than 20 million S4 smartphones by June 30, which is around 1.7 times faster than the Galaxy S III. As of October 23, 2013, Samsung has sold over 40 million S4 units six months after release. Battery problems and safety issues. This section relies too much on to.
