Old phone, new tricks

Galaxy upcycling is a brilliant initiative from Samsung that repurposes your old smartphone into a variety of smart home devices, such as baby monitors, security cameras and motion detectors. By using the Smartthings app, your old smartphone can be adapted to recognise a baby crying or dogs barking, for instance, sending your new phone alerts just like a smart home security system, and even turn on lights automatically when the old phone senses darkness in a room.
