Just like old PCs and laptops, there are plenty of ways to repurpose an old smartphone. If it has a functional camera, you could turn it into a makeshift webcam for your PC, or even a full-on surveillance system using a Frigate server. Alternatively, you could use its touchscreen display to build a reliable Home a**istant dashboard. Or, if you’re as much into productivity as I am, you could even repurpose it into a Stream Deck.
