I do some light local spoofing on my main account. Mostly just to raids to save on remote passes, and occasionally to areas with higher spawn density during events when I haven't had the time to physically go there myself. I've been using my old Samsung Galaxy Note 3 which has just turned 10 this year and is definitely showing it's age! Constantly crashes so I can't do much with it haha.
I have a Nexus 6P that while isn't much newer, I'm going to see if it performs any better.
I'm a light spoofer. I live in the boonies, so when I'm not hanging out with my folks playing for the day I will use PGSharp locally only, just to go into town and put myself in a gym, get more balls, etc.
My stepdad, on the other hand, is a maniac. He has multiple accounts across multiple devices, spoofs all over the world, and is a completionist like no other. Trying to get him into the mainline series, but he won't budge. He just drives around all day and spoofs all night.
