My last chinese budget phone had a notification light at the front. It was called Harlequin I think. It was handy to see if a message or a call had come through. Even though the phone looks like there is a notification light on the front I havn't managed to find a software setting to activate it. This phone comes with Android 7.0. It supports 4G VoLTE with dual SIM enabled 4G. It also supports Samsung Knox. [3] It is expected along with other phones including the Samsung Galaxy S8, Note 8, A7 (2017), J7 (2017), J3 (2017), S7, S6 and Note 5 to get Android 8.0 Oreo in 2018. As of 2018 August, Android 8.1 Oreo is available in Poland (for the SM-J530F). Android 9 Pie with One UI 1.1 is available as of 2019 September.

Usually cameras with larger sensors and less pixel density tend to provide better image quality despite the lower resolution.

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. talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 3G cellular network. Samsung’s updated Galaxy J5 does everything you could ask for. It’s a solid performer when put side-by-side with its competition, battery life is excellent, the new design is top-notch and its camera is far improved over last year’s effort. 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.Actually, it was not my first time flashing /e/ as I’m proudly using it for several months now on my SM-A520F.

Information about the manufacturer and model of the image sensor used by this camera of the device. talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 2G cellular network. Information about additional software and hardware features of the rear camera which improve its overall performance.Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width 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. stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 2G cellular network. 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. 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.

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. 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. 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. 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 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.

stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 3G mobile network. 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. Information about the height, i.e. the vertical side of the device when it is used in its standard orientation.
