Information about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well. 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. 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. Samsung Galaxy A5 (2016) was released in China on 15 December 2015. As of April 2016, the Samsung Galaxy A5 (2016) was available in Europe, [3] Africa, Latin America and Asia. 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.

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. 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. Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. 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. 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.

Summary

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.

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. 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. Samsung Galaxy A5 (2016) is powered by the Exynos 7580 (Exynos 7 Octa) SoC with a 1.6GHz octa-core 64-bit processor and Mali T720-MP2 graphics processor. The smartphone has 2 GB RAM and 16 GB eMMC internal storage with support for removable MicroSD cards of up to 128 GB. [1] The device's MicroSD card allows the insertion of a SIM card, thus it can also be used in Dual SIM mode. 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 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.The Samsung Galaxy A5 (2016) launched with the Android 5.1.1 "Lollipop" operating system. Samsung released the Android 6.0.1 "Marshmallow" update and then Android 7.0 "Nougat" update for the phone.

Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width 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. 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.

Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology 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. One of the main characteristics of the display is its type/technology, on which depends its performance.

Samsung's Galaxy A5 (2016) or Samsung Galaxy A5 2016 Edition is an Android smartphone developed by Samsung. 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. ApertureSuper AMOLED FHD display with Corning Gorilla Glass 4, 1080×1920 px, 2.5D, Colour depth 16M, 424 ppi Switching to /e/ OS ROM e-0.7-p-2020012238465-dev-a5xelte (pie) was uncomplicated, because the /data partition isn’t yet encrypted at the factory.
