Although Samsung is well-known for their Galaxy S and Note series of phones, they have the J and A series that covers that mid-range and budget categories. However, it looks like the company is killing off the J-series in a recent report.
The company will put a focus on their A-series which will cover the mid-range and budget price points. Other than that, the company has mentioned that they will introduce the Galaxy M-series that will replace the Galaxy On series. The M-series will cover the budget segment to compete with Chinese brands, as it might be an online-exclusive phone. Lastly, DJ Koh, CEO of Samsung has stated that they are changing how the company presents their phones to the public by introducing new tech into their Galaxy A series first before bringing it to their flagship models.
