GeorgeSoros The defaults are fine.
Those of us tired of constantly turning off the privacy invasive toggles in a maze of settings that (by the way) often get updated, requiring constant vigilance so settings are kept as private as possible
When have these settings ever been changed in a negative way in AOSP or GrapheneOS?
In stock OS you toggle off invasive settings only to discover deeper invasive toggles remain on. Simply put it's a labyrinth that no one should have to constantly monitor and dig into.
Unless you're talking about Google app/service settings, which aren't relevant to what's part of GrapheneOS, what do you mean?
App permissions
Standard permissions are disabled by default on Android. You can set the added Sensors permission as disabled by default for newly installed apps too if you understand you'll need to grant it to apps which need it and they won't know how to request it since it was added by GrapheneOS.
transfer permissions
USB file transfer, etc. are disabled by default on Android.
connectivity while blue tooth/wifi is off
That doesn't exist. There are opt-in toggles for Wi-Fi / Bluetooth scanning in the background while those are otherwise off by apps which you've granted the Location / Nearby Devices permissions.
Does GOS default truly dig deep into the labyrinth and neutralize all these sneaky settings and permissions?
There is no labyrinth in AOSP to begin with and GrapheneOS changes the defaults where it makes sense. Our features page documents some of the defautlts we change. We don't change the Wi-Fi / Bluetooth scanning toggle defaults, they're already off by default.
