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. 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 battery type is determined by its structure and more specifically, by the chemicals used in it. There are different battery types and some of the most commonly used in mobile devices are the lithium-ion (Li-Ion) and the lithium-ion polymer battery (Li-Polymer). 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)

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.

Conclusion of Huawei P30 Pro Firmware:

Information about the electric current (amperes) and voltage (volts) the charger outputs. The higher power output allows faster charging. Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. 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. a b Cutress, Ian. "Huawei Launches the P30 and P30 Pro: P is for Photography".

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. Upload video does not exceed 10M, supported formats are mp4, avi, wmv, mpeg, mov, mkv, flv, f4v, rmvb, rm, 3gp, dat, ts, mts, VOBThe 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 ISO rating or number is an indicator of how sensitive a camera's image sensor is to light. Image sensors operate within a specific ISO range. The higher the ISO rating is, the more sensitive to light the sensor is. 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.

We strictly recommend performing "Enable Downgrade" on "Flash" tab, as the first service operation on this device! photos maximum, each photo's size should be less than 10MB (bmp, jpg, png, gif, and jpeg are supported) 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 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 optical format of an image sensor is an indication of its shape and size. It is usually expressed in inches.

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.
