Charging was done within a few hours as opposed to a full day or night for the chinese budget variety. 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 Samsung Galaxy J5 (2017) has a 720x1280 (16;9 Ratio, 282 PPI Density) SUPER AMOLED Display. with a 5.2 (71.5% screen-to-body ratio) inch screen. 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. Now being fed up and the battery dying slowly I decided to go for a branded phone in the hope that the quality would be a little bit better with less bugs and it actually working.

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. SoCUMTS 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. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width 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 phone was about twice the price of the chinese budget phone I have had before for a year but it my opinion it is worthwhile. 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. [4] See also [ edit ] The capacity of a battery shows the maximum charge, which it can store, measured in mili-Ampere hours. 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 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. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.

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 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). 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. The Galaxy J5 2017 features a 13 megapixel rear camera with LED flash, f/1.7 aperture, auto-focus and a 13 megapixel front-facing camera with f/1.9 aperture, also equipped with LED flash. [2] The Galaxy J5 (2017) is available at the major carriers following the Galaxy J3. 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. Information about additional software and hardware features of the rear camera which improve its overall performance.
