About this deal

Information about the manufacturer and model of the image sensor used by this camera of the device. This SAR value considers the combined effects of using the mobile device as a Wi-Fi hotspot operating at the same time as other radiofrequency transmitters - cellular, Bluetooth, etc. 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. 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.

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.Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width This phone has Dual SIM capability, which means that you can insert two different SIM cards and use them both from one phone. The Galaxy S23 Ultra's IP68 certification guarantees protection against dust particles and water immersion up to a certain depth. Experience the convenience of fast charging with the Galaxy S23 Ultra smartphone, ensuring that you spend less time tethered to an outlet and more time enjoying your device's features. Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. The Samsung Galaxy S23 Ultra runs on Android OS v13.0 out of the box, but the Galaxy S23 Ultra's firmware can be upgraded to a newer version of OS. Android offers extensive customization options, allowing users to personalize their devices with different wallpapers, themes, and launchers. Users can also configure various settings to tailor the device's behavior to their preferences. The Samsung Galaxy S23 Ultra comes with Qualcomm Snapdragon 8 Gen2 chipset, accompanied by 8 GB of RAM and 128 GB of internal storage. GPRS, EDGE, CDMA2000 EV-DO Rev 0, CDMA2000 EV-DO Rev A, UMTS, HSDPA, HSUPA, HSPA+, TD-LTE, LTE, LTE-A, SA/NSA, Sub6

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 type 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. The fingerprint sensor in the Galaxy S23 Ultra is one of the easiest and most secure ways to protect your smartphone. By incorporating a proximity sensor, the Galaxy S23 Ultra smartphone offers enhanced usability and convenience, automatically adapting its behavior based on the user's proximity to the device. A notable feature of the Samsung Galaxy S23 Ultra smartphone is its inclusion of an ambient light sensor, allowing the device to adapt the screen brightness in real-time, delivering optimal readability and power efficiency throughout the day. 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.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. 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. 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 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. 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 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.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. 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 number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. Information about additional software and hardware features of the rear camera which improve its overall performance.
