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. Design Information about the dimensions and weight of the device, shown in different measurement units. Body materials, available colors, certifications. Width 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.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. 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.

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. talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 3G cellular network.

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. 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. talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 2G 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. 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. 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.Everything great? Almost, the cam stretches the pictures, and I hope to find a solution to this somehow. I wouldn’t even care about this little flaw but for my selfie, tictoc, snapchat etc. addicted kid the cam and picture quality are the most important part of the whole phone. 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.

Smooth operation through and through. No problems, quality is ok, a good workhorse I am looking forward to use for the next couple of years. 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 manufacturer and model of the image sensor used by this camera of the device. 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.

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. 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. 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. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.
