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. A veritable big battery smartphone, which close to the battery capacity of rugged phone(what's the meaning of it?). OSCAL C80 carries a 5180mAh battery to get you ready from daily media consumption to heavy workload. When a top-up is needed before a long-time online conference or outdoor activities, OSCAL C80 always gets itself refuelled in a flash with its 18W fast charging. Ultra-clear 1080p video recording makes your videos so visually appealing that no one can take their eyes off your video masterpieces 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. Information about the manufacturer and model of the image sensor used by this camera of the device.

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.The 6.5-inch In-cell display supports a staggering 180Hz touch sampling rate and a higher 90Hz refresh rate that enables OSCAL C80 to keep up with gaming action faster and makes navigating around breathtakingly smooth and responsive. 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. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM 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 Wi-fi Wi-Fi is a popular wireless networking technology using radio waves to provide high-speed network connections that allows devices to communicate without cords or cables, Wi-Fi is increasingly becoming the preferred mode of internet connectivity all over the world.

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 display is its type/technology, on which depends its performance. 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.

OSCAL C80 will be shipped with an octa-core Unisoc T606 as its CPU. Paired with 8GB RAM and up to 6GB RAM expansion for smoother multitasking, faster app-switching and launching speed. For storage capacity, OSCAL C80 is likely to deliver 128GB ROM and up to 1TB TF support to offer enormous space for entertaining digital content or important work files. OSCAL C80 delivers up to 6GB RAM expansion to enhance its capability to process multiple tasks simultaneously with less lag and greater fluency. Gamers witness better visuals while content creators benefit from faster app-launching and switching speed. 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.

OSCAL C80 will carry onboard a nice 5180mAh battery to get you ready for everything from daily media consumption to heavy workload. When you need a top-up before a long-time online conference or outdoor activities, you can get OSCAL C80 recharged in a flash with its 18W fast charging. 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 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. Information about additional software and hardware features of the rear camera which improve its overall performance. Information about the dimensions of the image sensor used in the device. Usually cameras with larger sensors and less pixel density tend to provide better image quality despite the lower resolution.Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. The Oscal C80 has a sleek and modern design, featuring a plastic body and a 6.52 inch LCD IPS screen. The device has a usable surface area of 81.8%, making it wide enough to fit comfortably in one hand without feeling bulky. The IPS screen has a resolution of 720x1600 (HD+) with a refresh rate of 90 Hz and a brightness of 400 cd/m² (typ).

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.
