We're really stretching the boundaries of "compact" here but the Xperia 5 fits the bill in one dimension — it's really narrow. On the downside, it's really tall. This year Sony completely changed the direction of its design and the Xperia 5 is part of the new lineup. It has the standard flagship specs for 2019: Snapdragon 855 and three rear cameras. The main difference from the Xperia 1 is the size. So, if you're looking for an all-around well performing and modestly sized smartphone that's not coming from Samsung, Google or Apple then this might be your best choice.
