Product Information

Battery The batteries of mobile devices differ in capacity and technology. They provide the electrical charge needed for the functioning of the devices. Capacity Information about the electric current (amperes) and voltage (volts) the charger outputs. The higher power output allows faster charging. 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 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). 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. 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 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.

[5] Camera [ edit ] 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 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.

The A40 is equipped with a dual rear camera arrangement with a 16 megapixel, f/1.7 aperture sensor as the main camera and an 'ultra-wide' 5 megapixels camera lens with an f/2.2 aperture as the second camera. [2] The front camera is 25 megapixels.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 number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width 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.
