There are "Other app capabilities" permissions in Google Play Services. It can be reached by:
Open the Android Settings app
Select Application
Select All applications
Select Google Play services
Select Permissions
Select App permissions
From the overflow menu, (three dots menu︙)
select All permissions
It's located at the bottom of the page when you scroll down. One of them is "Full access to the network", "...Not necessary for sending data to the internet, as the means to send data to the internet is provided by the browser or other apps".
I don't know how to turn off "Other app capabilities" in Google Play services.
I searched but could not find it.
Does anyone know how to turn it off?
