Admittedly, I haven't yet fully wrapped my head around how Play services and subservient apps (and other apps) interact when sandboxed. Not even sure which apps require play services, so any help there would be great. (I do not use any nfc payments, almost never pay for apps, I'm changing to a non-google messaging app, not really sure what else I might need services for except notifications?)
So is play services able to communicate with other apps in ways I don't want it to if I leave services (and all other apps) in the main owner profile?
