Smartphones are ubiquitous, but smartphone habits are as diverse as the people using them. I like to buy a flagship device, such as an iPhone X or Pixel 2, and use it for four or five years. Others buy into upgrade plans with their carrier that lets them change out their phone every year. But lots of people still buy a phone, keep it for a year or two, and then buy a new one; their old phone ends up in a closet, shoebox, or nightstand.
Many people save these old phones in case of emergency, but the vast majority of them never get used again, and eventually become worthless. The phone-in-the-closet phenomenon has become a hidden store of e-waste; a two-year-old phone still has value and is still a powerful device. And so it's great news that Samsung is starting a new "Upcycling" initiative that is designed to turn old smartphones and turn them into something brand new.
