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. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology 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 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 SAR head rating shows the highest level of exposure to electromagnetic radiation measured when the device is held next to the ear in a talk position. In Europe, the SAR limit for hand-held mobile devices is set to 2 W/kg per 10 g of tissue. This standard is specified by the CENELEC, complies with the IEC standards and follows the ICNIRP Guidelines 1998. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSMInformation about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU. Samsung Galaxy A21s is a mid-range Android smartphone designed, developed, marketed, and manufactured by Samsung Electronics as part of its Galaxy A series. 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) 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.

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 ]
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. Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. 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. 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. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. WidthThe 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. CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications. 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. One of the main characteristics of the display is its type/technology, on which depends its performance.
