The Samsung Galaxy S5 is an Android smartphone produced by Samsung Electronics. Unveiled on 24 February 2014 at Mobile World Congress in Barcelona, Spain, it was released on 11 April 2014 in 150 countries as the immediate successor to the Galaxy S4. As with the S4, the S5 is an evolution of the prior year's model, placing a particular emphasis on an improved build with a textured rear cover and IP67 certification for dust and water resistance, a more refined user experience, new security features such as a fingerprint reader and private mode, expanded health features (such as a built-in heart rate monitor), and an updated camera.
The Galaxy S5 received mostly positive reviews; The phone was praised for its display, hardware, camera and battery life but it was criticized for its plastic design, bloated software and the inconsistent fingerprint scanner featured on the phone.
In August 2015, following the release of its latest flagship, the Galaxy S6, Samsung released an updated version called the "Galaxy S5 Neo" which has a Exynos 7 Octa (7580) processor clocked at 1.6 GHz. It has 2 GB of RAM, 16 GB of internal storage and comes with Android 5.1.1 "Lollipop".

Release
The Galaxy S5 was unveiled on 24 February 2014 as part of the company's presentation at Mobile World Congress in Barcelona, Spain. Samsung Electronics president JK Shin explained that consumers did not want a phone dependent on "eye-popping" or "complex" technology, but one with "beautiful design and performance", a "simple, yet powerful camera", "faster and seamless connectivity", and fitness-oriented features.
Samsung announced that it would release the S5 on 11 April 2014 in 150 countries--including the United Kingdom and United States. On 18 June 2014, Samsung unveiled an LTE-Advanced version of the S5, exclusively released in South Korea. Unlike other models, the LTE-A version also upgrades the display to a quad HD, 1440p panel.
Shortly after the release of the S5, it was discovered that some Galaxy S5 devices--particularly those on Verizon Wireless, were suffering from a major bug that caused the device's camera hardware to permanently cease functioning, and display a "Camera failed" error on-screen whenever users attempt to use the camera. Both Samsung and Verizon confirmed the issue, which affected a limited number of Galaxy S5 devices; Samsung instructed users affected by the bug to contact the company or their carrier to have their phone replaced under warranty.

Specifications
Hardware and design
The design of the S5 evolves upon the design of the S4. It features a rounded, polycarbonate chassis carrying a "modern glam" look, faux metal trim and a removable rear cover. Unlike past models, the S5's rear cover uses a higher quality soft plastic and is dimpled to improve grip. The S5 is IP67 certified for dust and water resistance. As such, the phone is able to be submerged in water up to 1 metre (3.3 ft) for up to 30 minutes. The S5's Micro-USB 3.0 port uses a removable cover. The S5 is available in Charcoal Black, Electric Blue, Copper Gold, and Shimmery White color finishes. The S5's screen is a 5.1-inch (130 mm) 1080p Super AMOLED panel, which is slightly larger than that of the S4, and allows for automatic brightness and gamut adjustments.
Below the screen are three buttons. The physical "Home" button in the centre contains a swipe-based fingerprint scanner. The "Recent apps" and "Back" buttons are capacitive. In accordance with Android 4.0 human interface guidelines, the S5 no longer uses a "Menu" key like its predecessors, although its button layout is still reversed in comparison to other Android devices with the S5's button layout (such as the HTC One X and Galaxy Nexus, whose "Back" buttons are to the left of "Home").
The S5 includes a 16 megapixel rear-facing camera, which offers 4K video recording, phase detection autofocus (which can focus in around 0.3 seconds), real-time HDR photos and video, and an image sensor with Samsung's "Isocell" technology, which isolates the individual pixels inside the sensor to improve its ability to capture light and reduce crosstalk. Compared to conventional BSI sensors, this reduces electrical crosstalk by about 30 percent. Next to the camera's flash on the rear of the device is a heart rate sensor, which can be used as part of the S Health software. The top of the device has an IR blaster and headphone jack. The IR blaster is a transmitter only and it has a built-in database of devices that can be controlled by Samsung's Smart Remote application.
The S5 is powered by a 2.5 GHz quad-core Snapdragon 801 system-on-chip with 2 GB of RAM. Although not mentioned during the keynote presentation, a variant (SM-G900H) with an octa-core Exynos 5422 system-on-chip was also released in multiple markets. Like the previous model, it uses two clusters of four cores; four Cortex-A15 cores at 2.1 GHz, and four Cortex-A7 cores at 1.5 GHz. Depending on resource usage, the SoC can use the power-efficient A7 cores for lighter processing loads, and switch to the A15 cores for more demanding loads. Unlike previous iterations, however, the Exynos 5422 can run both sets of cores at the same time instead of only one at a time.
The S5 contains a 2800 mAh lithium ion battery; It is Qi compatible and also contains an "Ultra Power Saving" mode to extend further battery life; when enabled, all non-essential processes are disabled, and the screen switches to grey scale rendering. Samsung claims that with Ultra Power Saving on, an S5 with 10% charge remaining can last for an additional 24 hours in standby mode. Another improvement in power efficiency comes from the use of Qualcomm's envelope tracker, which reduces the power used in connectivity.
Software
The S5 shipped with Android 4.4.2 KitKat but has received updates, most recently including 6.0.1 Marshmallow). It has Samsung's TouchWiz software, which for the S5 has a flatter, more geometric look than that found on the S4. Certain aspects of the changes were influenced by a recent patent licensing deal with Google, which requires that Samsung's TouchWiz interface follow the design of "stock" Android more closely. The S5 adds the Galaxy Note 3's "My Magazine" feature to the leftmost page on the home screen, the Settings menu was updated with a new grid-based layout, a Kids' Mode was added, while the S Health app was given expanded functionality, integrating with the new heart rate sensor on the device, along with the new Gear 2 smartwatch and Gear Fit activity tracker. The "Download Booster" tool allows internet usage to be split across LTE and Wi-Fi to improve download speed. Due to carrier policies, Download Booster was not available on Galaxy S5 models released in the United States running KitKat 4.4.2, excluding T-Mobile US and U.S. Cellular.
The S5 contains a number of new security features. The fingerprint reader can be used to unlock the phone, while an SDK is available so third-party developers may offer fingerprint-oriented functionality in their apps; for example, PayPal integrated support for the fingerprint sensor to authenticate online purchases. The S5 also adds "Private Mode", which allows users to maintain hidden apps and file folders that cannot be accessed without additional authentication. The camera app was updated with a new "Shot & More" menu that allows users to make edits to photos after they are taken, and also adds a new selective focus mode.
An update to Android 5.0 "Lollipop" was first released for S5 models in Poland in December 2014. The update incorporates performance improvements, an updated "Recent apps" view that utilizes a card-based layout, access to notifications on the lock screen, and modifications to the TouchWiz interface to adhere to Material design language. In April 2016, Samsung released an update to Android 6.0.1 "Marshmallow" for international S5 models. It enables new features such as "Google Now on Tap", which allows users to perform searches within the context of information currently being displayed on-screen, and "Doze", which optimizes battery usage when the device is not being physically handled.
Variants
Samsung released two rugged versions of the S5, the S5 Active and S5 Sport. Both models feature a version of the S5's design with a full set of physical navigation buttons and do not include the fingerprint scanner, but are otherwise identical to standard models of the S5. Both devices also include an exclusive "Activity Zone" app, which contains a barometer, compass, and stopwatch. The S5 Active adds an "Active Key" to the side of the device, which can be configured to launch certain apps on short and long presses; by default, the button launches Activity Zone. The Sprint S5 Sport has additional Sprint Fit Live software, which acts as a hub for health-oriented content and S Health, along with the Under Armour-owned MapMyFitness MVP service and the music streaming service Spotify--the device comes with complimentary subscriptions to both services. Both models come in different color schemes (grey, camouflage green, and red for the S5 Active, and blue and red for the S5 Sport), and the S5 Sport is slightly lighter in weight than the S5 Active, at 158 g (5.6 oz) instead of 171 g (6.0 oz). The S5 Active and S5 Sport were released in the United States in June 2014, and are exclusive to AT&T and Sprint respectively. The S5 Active was released in Canada in October 2014.
In June 2014, Samsung also released a dual SIM version of the Galaxy S5, called Samsung Galaxy S5 Duos, model SM-G900FD. The Duos has the LTE specification of the Galaxy S5.
A hardware revision called the Galaxy S5 Neo was quietly released in August 2015. The S5 Neo is a lower cost variant of the original Galaxy S5 that employs downgrades de SoC to an Exynos 7580 Octa system-on-chip, although improving the front camera to a 5-megapixel unit. Other changes include the lack of a fingerprint sensor and a conventional USB 2.0 port in lieu of a USB 3.0 port with a water-resistant cover, the latter of which has been a source of complaints from users who found the cover to be easily broken from regular use with the last year's model. The S5 Neo is currently available in Europe (SM-G903F) and Canada (SM-G903W).
Reception
Critical reception
The S5 received positive to mixed reviews; critics acknowledged that the S5 was primarily a technological evolution of its predecessor with few changes of significance. Although praised for an improved appearance and build quality, the design of the S5 was panned for retaining a nearly identical appearance and construction to the S4, and for not using higher quality materials such as metal or a higher-quality plastic. The display of the S5 was praised for having a high quality, not being as oversaturated as previous models, and having a wide range of viewing angles, brightness states, and gamut settings to fine tune its appearance. TechRadar also noticed that, despite the high power of its processor, some apps and interface functions suffered from performance issues, indicating that the S5's operating system may not have been completely optimized for its system-on-chip. The S5's interface was praised for having a cleaner appearance than previous iterations--however, it was still criticized for containing too many unnecessary features and settings.
The S5's camera received mostly positive reviews for the improvements to image quality provided by its Isocell image sensor, but was deemed to still be not as good as its competitors, particularly in the case of low-light images. While the S5's camera interface was praised for having a streamlined design, it was criticized for taking too long to load, and the Selective Focus features were panned for being inconsistent in quality. While praised for providing more uses than the Touch ID function on the iPhone 5s, the fingerprint sensor was panned for requiring an unnatural vertical swiping gesture, having inconsistent and unforgiving results, and for being inconvenient in comparison to a password or PIN in most use cases due to these shortcomings. The Berlin-based Security Research Labs found that because the S5's fingerprint sensor could easily be spoofed, allows unlimited chances and does not require a PIN after 48 hours of inactivity or on startup like Touch ID, and can be used for more than just unlocking the phone, it "gives a would-be attacked [sic] an even greater incentive to learn the simple skill of spoofing fingerprints." Engadget considered the heart rate sensor to be similarly unforgiving and sometimes being inaccurate in comparison to other heart rate trackers, while The Verge felt that it was a redundant addition due to the concurrent introduction of the Samsung Gear Fit, which includes a heart rate tracker of its own, and is likely to also be purchased by those wanting to take full advantage of the S Health software on their S5.
Sales
The S5 shipped to retailers 10 million units in 25 days, making it the fastest shipping smartphone in Samsung's history. Samsung shipped 11 million units of the S5 during its first month of availability, exceeding shipped units of the S4 in the same period by 1 million units. However, 12 million units of the S5 were shipped in its first three months of availability, which is lower than the S4's sales.
Due to the lower sales of the S5, in July 2014, Samsung reported its lowest profits in over two years, and a drop in market share from 32.3% to 25.2% over the past year. The loss in market share was attributed primarily to growing pressure from competitors - especially in the growing low-end smartphone market, and an already saturated market for high-end smartphones. By the end of 2014, it was reported that sales of the S5 were 40% down on the previous S4 model, prompting management changes at Samsung.
