It's pretty simple: buy a device that is supported by the manufacturer for the lifetime of the device. The Nexus 5X was released in 2015, so it's abandoned after three years. The oldest supported iPhone is the 5s, which was released in 2013 and will be supported by iOS 12 which means it gets security updates until at least fall of 2019 (maybe longer). A straight-from-Google Android phone is out of support after 3 years, while a comparable iPhone is still supported after 6 years.
