Although not perceived to offer as much value for the money as its spiritual predecessor, the original Google Nexus 5, the Nexus 5X is still a pretty decent upper mid-range smartphone, especially at $379 for the 32GB version. Aside from the vanilla version of Android and the promise of timely Android updates, the strong points of the handsets are a versatile 12MP primary camera, a fast battery recharge time, as well as color-accurate 5.2-inch FullHD display.
