Samsung Galaxy J series

The Samsung Galaxy J series is a discontinued line of entry-level 32-bit Android smartphones produced by the South Korean company Samsung Electronics, first introduced in 2015 and focused on emerging markets. This series is a part of Samsung Galaxy series, preceding the current Galaxy M Series and placed below the mid-range Galaxy A Series.

History
Being mainly positioned low-end segments, all models in the series have the essential features of a standard entry-level smartphone, and differ in size and design. The letter J stands for "Joy" or "Junior". However, new features such as slow motion and video recording at any resolution above 1080p and any frame rates above 30 frames per second are left out entirely.

Other materials are used, with Samsung targeting Asian markets or the European entry-level market. The models are updated at least annually, minor updates or variants are displayed with name additions such as Pro, Prime, Max, etc.

Despite having a similar name, the original Galaxy J (SGH-N075/SC-02F), released in 2013, does not actually belong to the Galaxy J series as this phone was only available in few markets, and also positioned as a high-end smartphone based on the Samsung Galaxy S4.

In September 2018, there were rumors that Samsung will reorganize their smartphone lineup by discontinuing the Galaxy J series along with the online-exclusive Galaxy On in favor of extending the mid-range Galaxy A series to lower-end segment and introducing the Galaxy M series as the new online-exclusive series of smartphones to better compete against the increasingly popular Chinese manufacturers, such as Huawei, Oppo, Vivo, and Xiaomi in the budget smartphone market. Samsung later introduced M10 and M20 in January 2019, followed by Galaxy A10, A30, and A50 the following month, and eventually announced that the Galaxy J series has officially merged into the Galaxy A series during the 2019 Galaxy A series launch event in April 2019 held in Thailand.

Successor
The Galaxy J series was discontinued in April 2019 in favor of extending the mid-range Galaxy A series into the entry-level segment, as well as introducing the online-exclusive Galaxy M series. The 2019 lineup also introduced Samsung's new naming scheme, with two-digit numbers as opposed to single digit of previous generation models.
