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. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.

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. 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. 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 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. Octa-core (1x3.36 GHz Cortex-X3 & 2x2.8 GHz Cortex-A715 & 2x2.8 GHz Cortex-A710 & 3x2.0 GHz Cortex-A510) 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.

Information about the manufacturer and model of the image sensor used by this camera of the device.In photography, the Field of view (FoV) depends not only on the focal length of the lens but also on the sensor size. It is derived from the lens's angle of view and the sensor's crop factor. The lens's angle of view is a measure of the angle between the two farthest separated points within the frame measured diagonally. Simply put, this is how much of a scene in front of the camera will be captured by the camera's sensor. GPRS, EDGE, CDMA2000 EV-DO Rev 0, CDMA2000 EV-DO Rev A, UMTS, HSDPA, HSUPA, HSPA+, TD-LTE, LTE, LTE-A, SA/NSA, Sub6 One of the main characteristics of the display is its type/technology, on which depends its performance. 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. 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.

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 additional software and hardware features of the rear camera which improve its overall performance.

Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation. 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 This value represents the localized absorption of RF energy when using a phone as a Wi-Fi hotspot or tethering it to another device. The hotspot SAR value is important for users who often share their mobile device's internet connection with other devices. The L3 (level 3) cache memory is slower than L2, but has a larger capacity, instead, which allows it to cache more data. Just like L2, it is much faster than the system memory (RAM). 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. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technologySpecific 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 Galaxy S23 Ultra smartphone comes with integrated Bluetooth functionality, enabling users to enjoy the convenience of wireless connectivity for file transfers, audio streaming, and hands-free communication. This smartphone has a built-in GPS receiver. GPS is a satellite based navigation system that allows the determination of the exact geographical location on Earth. The Galaxy S23 Ultra comes with Near Field Communications (NFC) functionality for transferring content with other NFC-enabled devices. 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. 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.
