I see lots of references to the "power" of permissions here. I had an experience you all should know about.
Before I switched to Graphene, I had Amazon loaded on my old phone. I wouldn't do that now, but this is still relevant. I had the phone in a room where a friend and I were having a conversation about an astrolabe that he bought. If you haven't heard or those, join the crowd, almost nobody knows what that is. This word almost never shows up in a conversation anywhere by anyone. When I next opened the Amazon app, it's vomiting out "suggestions" for astrolabes. This is with ALL the permissions turned of on both my phone and the Amazon account. I routinely spent lots of time checking on and switching off permissions. That was when I switched over to Graphene.
I get that open source apps are probably better, and you don't put predator apps on your privacy phone, but corporate predators aren't the only spies raping your phone, and they aren't even the worst. If Amazon can do this without breaking a sweat, I'm guessing the government predators can too, no app needed. I know this will piss lots of people off because we are all desperate to get our privacy back or we wouldn't put up with the occasional inconvenience of Graphene, but you all need to know that they are probably using tech that none of us have even dreamed about, and that your phone is always your enemy. Yeah, paranoid, blah blah. Whatever. Just a good idea to watch what you say around your phone no matter what.
