Question: what is the difference between j series and a series?
Answer: With the J series, Samsung is more focused on affordability rather than performance. That's why the best, priciest, and most recent member of the J series (Galaxy J8) come with a 1.8GHz Octa Core processor and 3GB RAM, whereas that of the A series clocks up to 2.2GHz and come with 6GB of RAM.
