Samsung Galaxy A9 (2018)

Samsung has suddenly become a lot more adventurous of late. There's been a flurry of launches over the past few months, and it looks like the Korean giant is catching on to the fact that it needs to innovate and jump on board with trends as they happen. We usually see new top-end features debut with the flagship Galaxy S and Galaxy Note series, and then trickle down to the mid-tier A-series and youth-focused J-series. For example, Samsung was one of the first to introduce tall, narrow Infinity Display screens, but it took ages for this well-received feature to show up on lower-tier offerings. Competitors caught on much sooner, and began selling low-cost phones that looked much more modern and sleek than Samsung's own.
