Information about the height, i.e. the vertical side of the device when it is used in its standard orientation. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. 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. 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.Samsung improved the Galaxy J1 (2016) in some important areas, but it is still clearly an entry-level device. The biggest problem is Samsung's own Galaxy J3, which is currently hardly more expensive and therefore offers the better price-performance ratio. The Galaxy J1 comes with a 4.3-inch PLS LCD display with a resolution of 800×480 pixels. There's nothing special about the viewing experience on offer here. Being an LCD unit, the colors aren't at all vibrant, and the display feels a tad drab in terms of colors and contrast. The viewing angles are also average – you will be able to make out what's on the screen when viewing it an angle, but you won't find it to be as clear as it would be on more high-end handsets (which isn't unexpected given the price range.)

It's shipped with Android 5.0.2 "Lollipop" which is upgradable to 5.1.1 as of September 2015. [7] [12] See also [ edit ]

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. One of the main characteristics of the display is its type/technology, on which depends its 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. 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. 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. The Galaxy J1 was announced in January 2015 as the first model of the J series. The 3G model was released in February 2015, the 4G model one month after. [8] [2] In the following months Samsung launched more smartphones bearing the J1 name such as the J1 Ace/Ace Neo, J1 Nxt/mini and J1 mini prime.
