Samsung Xcover 4 UK SIM-Free Smartphone - Dark Silver

Product Information

Information about additional software and hardware features of the rear camera which improve its overall performance. Samsung's XCover 4 uses quite a few hardware buttons. The Android menu buttons are situated below the screen. They have a clear pressure point and make a robust impression. The standby button is on the casing's right, and the volume control and a dedicated XCover button are found on the left. Short pressure enables the flashlight, and longer pressure launches the camera. All buttons are easy to feel and have a clear pressure point. This SAR rating shows the maximum level of exposure to electromagnetic radiation taken when the device is placed next to the ear. The applicable limit for the US is 1.6 W/kg per 1 g of tissue. In the US the FCC tests and sets the SAR limits for all mobile devices, which are controlled by the CTIA.

One of the main characteristics of the display is its type/technology, on which depends its performance. 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.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 capacity of a battery shows the maximum charge, which it can store, measured in mili-Ampere hours. 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. 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. The SAR body rating shows the maximum level of exposure to electromagnetic radiation when the device is positioned against the body at the hip. The highest SAR value of mobile devices allowed in the US is set to 1.6 W/kg per 1 g of tissue. It is specified by the FCC and the CTIA follows whether the mobile devices comply with this standard.

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. Like its predecessor, the Galaxy XCover 4 is not suitable for extreme situations, but quite well-equipped for the uncertainties of everyday life. The hard shell conceals a solid, lower mid-range smartphone. Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. 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. 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)

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. 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. As usual with Samsung, there are many aids for disabled users and diverse control options, such as turn to mute, emergency messages or display several apps simultaneously via a multi-window display.
