The Samsung Galaxy J4 did not officially sell as well across Western and Central Europe as in South Korea and Australia[citation needed] because this model may have been deemed too similar to the predecessor,Galaxy J3 (2017).,Galaxy J4+ was released as the replacement for J4. It was perhaps the last Samsung phone incorporatingGalaxy S6 design language, albeit with the key symbols from theExperience UI.

The J4 features a 5.5-inch SuperAMOLED display with a 720×1280pixeldisplay resolution and apixel 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 andHDR mode. The front camera features 5 MP and f/2.2 aperture.[2]
