My last phone upgrade was about four years ago (Nokia 6 to Samsung A31) and that was only to try and get YouTube Music’s shitty app to work properly (spoiler : it didnt). Broke the screen on it dropping it while trying to put a mask on, got that fixed (that was over two years ago). Its still going, and will keep it until it dies
I dont upgrade my phone because I’m interested in upgrading, I upgrade when I have to
