as a new graphene adopter, still figuring stuff out myself, but it's been surprisingly easy and satisfying to do a hard cut-over to graphene.
cool_cherry explained exactly how I've been using it, with my main 'owner' account not having play services installed at all, only instead installed on another user, which only takes a few seconds to switch to.
you can easily install owner apps onto other user profiles.
or grant/forbid the other user profiles to install apps themselves.
users are not tied to google accounts, only your google play installations.
I was able to install google play apps on 'owner' user and then uninstalled google play services and play store. if they don't require play services to function, they work fine, otherwise they just might not function or may function/look surprisingly differently when they don't have their network connections.
location, network, other permission have defaults and can set them on per-app basis like on normal android.
a unique device MAC address is generated for each wifi connection.
The "upscaling" significantly changes the content of the picture, altering half of the faces, their expressions, whether eyes are closed, mouths open, etc, on top of making it actually HARDER to see details.
The "upscaling" on android smartphone cameras has always been similarly trash. There is always some odd fractal-looking noise filter added.
Who is actually asking for this stuff?
and they want me to pay $100+ a month to be their training?
i hope we can find morality again.
