So I got a Pixel from eBay, by chance it had Graphene pre installed (was just hunting for a Factory unlocked phone) What would be the best course of action before I start using it, to be sure there isn’t anything malicious on there?
*Will “Erase all data (factory reset)” be enough?
*Do I need to use the Auditor App ( I don’t have a second android phone atm, I currently have only iphones)
*Use the GrapheneOS Web installer to re-install a fresh copy?
Cheers.
