Today is Earth Day, and to appreciate and celebrate it, Samsung has announced the beta of its Galaxy Upcycling at Home program in countries such as the U.S, UK, and Korea. The program was first announced at CES 2021, and it allows anyone with older Samsung Galaxy smartphones to repurpose their phones using the SmartThings app instead of just tossing them or selling them.

As per  Jaeyeon Jung, VP & Head of the SmartThings team, Galaxy Upcycling at Home can actually open a world of possibilities and essentially allow everyone to turn their home into a smart home.
