Samsung makes it easy for (almost) anyone to upcycle (some of) their old phones
More specifically, you can turn your Galaxy S, Note, or Z-series phone released after 2017 into an IoT (Internet of Things) device capable of detecting certain sounds of interest, as well as measure the brightness level of a predefined room.

The former's goal is for your old handset to accurately distinguish sounds in everyday surroundings and alert you when a baby is crying, a dog is barking, or someone is knocking at your front door, for instance. Meanwhile, the latter use case could come in handy to automatically turn on the lights or the TV when your room gets darker than you'd like, interacting with other devices in the SmartThings ecosystem to make your life easier.
All in all, those are some pretty specific (and one might argue rudimentary) features, but if you're not using your Galaxy S9 or Note 9 for much else these days, that sure beats simply throwing away said phones and negatively contributing to the world's growing e-waste burden.
