The "dynamic" mode tends to overemphasize all colors; "video" comes closest to the objective ideal, including its grayscale rendering. In the "dynamic" mode, on the other hand, grays tend to come with a (barely) noticeable greenish tint. Still, grayscale reproduction works rather well, remaining almost lifelike in all modes on the Galaxy S4. KitKat rolls out for Galaxy S4, Note 3 in UK and US". ZDNet. CBS Interactive .

Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc. Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications.The Galaxy S4's successor, the Samsung Galaxy S5, was announced by Samsung in February 2014 ahead of a release in April of that year.

These interaction features were later inherited by the Galaxy Note 3 and the Galaxy S5, but most of those features were gradually removed from Samsung's flagship phones released afterwards.Information about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen. A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel. These features and sensors are available and optionally utilizable for users and software that needs them. At retail, the S4 is bundled with a USB cable, AC adapter, and in-ear headphones. [18] The "S-View Cover" accessory "closes" the phone. When this cover is detected (by a hall effect sensor), the time and battery are displayed in this cover's window area. [102] [103] Reception [ edit ] Critical reception [ edit ] 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 Galaxy S5). [120] [121] The Galaxy S III sold 4 million units in 21 days, the Galaxy S II took 55 days and the Galaxy S took 85 days. [122]
Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM Unlike the predecessor, the S4 is also equipped with a hall sensor for the S View cover, a self-capacitive [29] touch screen layer for Air View and thermometer and hygrometer sensors, [30] [7] the last two of which only the Galaxy S4 and Galaxy Note 3 out of all historical Samsung flagship devices are equipped with. 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, [39] although no precluded video recording capabilities beyond 1080p at 30fps. Information about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU. 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. [113]

Davies, Chris (15 May 2013). "Samsung Galaxy S4 already hits 6 million sales". TechRadar. Future plc . Retrieved 16 May 2013. Apart from mobile phone and data connections, the Samsung Galaxy S4 supports all Wi-Fi standards - next to 802.11 b/g/n even 802.11 ac, a standard for the 5 GHz band which is still under development, but which is supposed to reach speeds of up to one Gigabit per second. Again, the reception quality is worse than with the Samsung Ativ S: Ten meters (~33 feet and two walls) away from the router, just three out of four barsremain, at times dropping down to one bar when another five meters (~16 feet) and another wall) are added. In all of these scenarios, the Ativ S showed full reception.
