The Samsung Galaxy J4 was never being sold officially in Western and Central Europe as well as South Korea and Australia because this model deemed too similar to the predecessor, Galaxy J3 (2017). It was being probably the last Samsung phone incorporating Galaxy S6 design language, albeit with the key symbols from the Experience UI.
The J4 features a 5.5-inch Super AMOLED display with a 720×1280 pixeldisplay resolution and a pixel density of 267 ppi which is protected by 2.5D Glass. The rear camera has a 13 MP sensor with f/1.9 aperture, autofocus, LED flash, panorama and HDR mode. The front camera features 5 MP and f/2.2 aperture.[2]
