Nexus devices are made in conjunction between Google (software maker) and a manufacturer (hardware maker) - in this case the Nexus 5X is manufactured by LG.
Specs
Pros
Pro Solid camera performance
LG made the hardware for the Nexus 5X, and they know a thing or two about smartphone cameras. They've added in laser auto-focus, as well as a larger pixel (1.55µm) for improved low light photography. The 12.3MP sensor might not have as many megapixels as competitors, but it still manages to deliver very solid results.
Cons
Con Charging port isn't backwards compatible
Old micro USB cables will not work with this device, meaning if you lose or break your cable you will need to buy a new one instead of using an old cable you had lying around. If you need to top up your phone away from home, it will be much harder to find a suitable cable initially.
