Agree with the other new users here. The GrapheneOS web install was a mindboggling experience. ("It can be this easy? Huh? Why doesn't everybody do it this way?")
SideofBurritos was stellar for repeating the instructions and adding in those tips and bits of reassurance newbs need!
Next stage: getting blankety-blank GOOGplay to work so I can get banking apps. The nice experience went straight downhill as soon as I had to deal with goog. Not Graphene's fault! (I have a goog account from back in the Stone Age, 10 years ago?, and goog wants everything including my hat size to get that going again. After Graphene, it feels like trying to scrape off cooties constantly.)
Also want to do some fun stuff: wallpapers, ringtones :D I could transfer the files over to the relevant directories if I knew what Graphene uses for that. A search didn't turn it up. Off to do some more hunting.
