Imagine our surprise when the first smartphone with upgradable internal storage wasn't a Project Ara phone from Google, it was a Nexus 5 from LG. Project Ara is still a concept - blocks that fit in to a smartphone casing, allowing you to upgrade whenever you like. The LG Nexus 5, on the other hand, is a device made back in 2013. Hardly the age of a device we'd expect to be so versatile. But here it is - the way in which you might upgrade your own internal storage from a paltry 16GB all the way up to a hefty 64GB - easy peasy.
