What do you mean? Do you have an example? Is this some kind of work-around?
If I'll give these permissions to Google Services, it means any app also using Google Services will automatically have access to the allowed resources.
None of the Google apps respect me. The maps app makes me disagree to giving enhanced location tracking every time I turn on location. The music player has a big bar constantly at the top that says "Downloaded Only," which if I accidentally tap it turns off downloaded only mode and kicks me to the store. If I leave location on accidentally, the camera app will sometimes use location to guess where I took a picture and ask me to "share" that. I don't use Google search, but I can't remove the giant search bar from the main screen or the shortcut if I accidentally hold the menu button.
Those are the only Google apps I use, and they all disrespect me. I only use a bit of Google but it's exhausting to even use just that bit.
My biggest concern is, even if I trust Google Services to have access to all of those requested permissions (consequently allowing the designated app Gmail, Maps, etc to access them) will these resources (permissions granted) be available to any app using Google Services?
