The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute. The Samsung Galaxy A21s has a four camera setup arranged in an "L" shape located in the corner with a rectangular protrusion similar to that of the iPhone 11 and the Pixel 4. The array consists of a 48 MP wide angle camera, an 8 MP ultrawide camera, a 2 MP macro camera, and a 2 MP depth sensor. [3] It also has a single 13 MP front facing camera, which sits in a small punch hole on the front of the screen. The rear facing cameras can record video up to 1080p in 30 fps. The front cameras can shoot 1080p at 30 fps. [4] Software [ edit ] Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor.
Information about additional software and hardware features of the rear camera which improve its overall performance. Information about the height, i.e. the vertical side of the device when it is used in its standard orientation.One of the main characteristics of the display is its type/technology, on which depends its performance. In India, the applicable limit for the head SAR is 1.6 W/kg per 1 g of tissue. Locally, the SAR levels are measured and certified by the Telecom Engineering Centre (TEC) or an internationally accredited lab. The Samsung Galaxy A21s SM-A217F is an Android Smartphone. It has 6.5 inches, HD+ 720 x 1600 Pixels screen resolution. And it is powered by Exynos 850 Octa-Core CPU, and runs Android 10.0. The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. The Galaxy A21s has a 6.5" PLS TFT LCD Infinity O display with HD+ 720 x 1600 resolution, 20:9 aspect ratio, ~270 ppi density. The phone itself measures 163.7mm (6.44in) x 75.3mm (2.96in) x 8.9mm (0.35in) and weighs 192g (6.8oz). The phone is powered by Exynos 850 (8 nm) SoC ( System on a chip) with a octa-core (4x2.0 GHz Cortex-A55 & 4x2.0 GHz Cortex-A55) CPU and a Mali-G52 GPU. The phone comes with either 4GB or 6GB RAM as well as 64GB or 128GB internal storage, which can be expanded via a microSD card of up to 512GB. It comes with a non-removable 5000mAh lithium polymer battery which charges with a 15W Fast Charger. It also has a rear-mounted fingerprint sensor. [1] Cameras [ edit ]
This SAR rating shows the highest level of exposure to electromagnetic radiation measured when the device is placed at the hip level. The top SAR value for mobile devices used in Europe is limited to 2 W/kg per 10 g of tissue. This standard follows the ICNIRP Guidelines 1998 as well as the IEC standards and is determined by the CENELEC. In August 2021, It was revealed that Samsung had sold over 10 million units of the Samsung Galaxy A21s. The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display.

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. The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC The phone runs on a Samsung Exynos 850 processor. It is available in three configurations: 32 GB storage/3 GB RAM, 64 GB storage/4 GB RAM, and 128 GB storage/4 GB RAM. Android 10 and Samsung's One UI 2 are pre-installed. Overall performance is solid, though not top of class. The phone will manage just about any task you throw at it. Game settings will need to be turned down, and you may experience a slight hesitation in loading now and again but no major lagging or stuttering. Quad Camera This Samsung smartphone gives the user 3GB / 4GB / 6GB of RAM. Where the Android Operating System is running, In addition to the user applications and games. And for the storage space it has 32GB / 64GB of internal storage and Up to 512GB of external memory via microSD card.
Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation. UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width Front camera Modern smartphones have one or more front cameras and their positioning has led to various design concepts – pop-up camera, rotating camera, notch, punch hole, under-display camera, etc. Sensor formatA 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. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted. Specific Absorption Rate (SAR) The SAR rating shows the amount of electromagnetic radiation absorbed by the human body when using a mobile device, expressed in W/kg. Head SAR (EU)
To capture and share the best memories of your life with family and friends, You can use the front selfie camera which has 13 megapixels of resolution. And the ( 48.0 MP Wide + 8.0 MP Ultra-Wide + 2.0 MP Depth + 2.0 MP Macro) Quad main camera with Flash and Auto Focus features. RAM, 32GB 3GB RAM, 32GB 4GB RAM, 64GB 3GB RAM, 64GB 4GB RAM, 64GB 6GB RAM, 128GB 3GB RAM, 128GB 4GB RAM, 128GB 6GB RAM 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. One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions.The A21s line consists of SM-A217F, SM-A217F/DS, SM-A217F/DSN, SM-A217M and SM-A217M/DS. Key upgrades over the previous model, the Samsung Galaxy A20s, include the new Exynos 850 chipset and an improved camera setup. It was announced and released in May 2020. 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. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM Pixels are usually measured in microns (μm). Larger ones are capable of recording more light, hence, will offer better low light shooting and wider dynamic range compared to the smaller pixels. On the other hand, smaller pixels allow for increasing the resolution while preserving the same sensor size. The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.
