Colvdv I did recently add a new SIM, but other than that my setup is the same.
The phone is older than it was, the cable has been flexed, and the power supply is older. You have likely updated GrapheneOS, likely including new firmware.
Your setup may look the same to the naked eye, but something is not the same in a way that matters.
Maybe it will keep working (good!) or maybe one of the parts is slowly becoming flakey over time, so there are going to be good days and bad days.
