I've done it for Pokemon Go. There are (were, it's been a while) pretty specific setup steps required, and it changed over the course of a couple of years as Android changed things up. One of the older methods worked, but semi-required the back of the phone to have aluminium foil on it so that the real GPS signal wouldn't get through and "rubberband" you back to your actual location, earning a soft-ban. I had more than one phone with a couple of layers of alfoil between the phone and the case. There was another method that required a specific version of Google Play Services, so that root wasn't necessary. I think. Also had to rename the FakeGPS app, and use Magisk Hide Good times. I enjoyed "seeing if I could" more than the actual fruits of the labour.
