The Samsung Galaxy J4 is an Android smartphone developed by the South Korea n manufacturer Samsung Electronics. Announced on May 22, 2018 and released the same day, the J4 is the successor to the Galaxy J3.[1]
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.
