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. Out of all of Samsung's new A series line-up, the Galaxy A40 is the easiest to hold in one hand as it's the shortest and narrowest of the bunch. 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 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). Information about the height, i.e. the vertical side of the device when it is used in its standard orientation.

The Samsung Galaxy A40 has a 5.9-inch Full HD+ (1080 x 2220) display with a Super AMOLED panel producing punchy, bright visuals. 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. The Samsung Galaxy A40 SM-A405FN is an Android Smartphone. It has 5.9 inches Main Display with FHD+ 1080 x 2340 pixels of Resolution. This Samsung device is powered by Exynos 7885 CPU and Mali-G71 MP2 GPU. 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 It measures 144.3 x 69.0 x 7.9mm and we were easily able to hold and operate the phone in one hand during our time with it.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. Information about additional software and hardware features of the rear camera which improve its overall performance. The Samsung Galaxy A40 is a more compact variant of the Samsung Galaxy A30, being sold mostly in markets where the Galaxy A30 is not available. [ citation needed] Specifications [ edit ] Hardware [ edit ] This Samsung smartphone gives the user 4GB of RAM memory. Where the Android Operating System is running, In addition to the user applications and games. And for the storage space it has 64GB of internal storage and Up to 512 GB of external memory via microSD card. 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 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. Maximum video recording resolution is 2336x1080 pixels (Full mode). [2] Audio recording with internal microphones is stereo. Audio recording with external USB microphones is supported but is mixed to mono.

🔋 Battery

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