NFC NFC (Near field communication) is a set of standards for smartphones and similar devices to establish peer-to-peer radio communications with each other by touching them together or bringing them into proximity, usually no more than a few inches. 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 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). Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSMInformation about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well. T606: Entry level octa core SoC with two fast ARM Cortex A75 cores at up to 1.6 GHz and six power efficient ARM Cortex A55 cores at up to 1.6 GHz. The SoC furthermore includes a LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), an ARM Mali G52MP2 GPU and a tri core ISP. The chip is manufactured at TSMC in 12nm FinFET.» Further information can be found in our Comparison of Mobile Processsors. 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. 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.

Ultra-clear 1080p video recording makes your videos so visually appealing that no one can take their eyes off your video masterpieces

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. Bluetooth Bluetooth is a wireless communications technology for exchanging data between mobile phones, headsets, computers and other network devices over short distances without wires, Bluetooth technology was primarily designed to support simple wireless networking of personal consumer devices.

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. 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. Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications.Crop factor is the ratio of the dimensions of a full frame camera's sensor (36 x 24 mm, which equals the frame size of a 35 mm film) and the dimensions of the image sensor of the device. The number shown is the ratio between the diagonals of a full frame sensor (43.3 mm) and the sensor in question.
