Still tweaking my user profiles and hit a snag.
I have one for Amazon/Audible, and as all other profiles I have them locked down to bare minimum that is required to function.
However, I was listening to a book yesterday and I was missing calls because I did not give access to phone for the profiles.

My question is, is there an issue with enabling it in profiles with big tech or other apps? Can these other apps get any info from the phone/messaging app?
I notice it doesn't give access to contacts or favorites, but it does have phone numbers, call history, and message history.
Wondering if this is risky behavior in a profile with big tech apps.

Normal phone calls can be answered from any user profile, even if the user profile does not have the SMS or phone calls permission enabled in Settings (that toggle enables the user profile to make phone calls).

However VoIP calls (e.g. Signal, WhatsApp, etc.) in another user profile can't be answered. You have to decline the call, switch the user profile where you have the app installed, and called them back. Whilst GrapheneOS does improve user profile functionality, this is unfortunately still one limitation.

Thanks, i'll have to keep playing around with it until i get to a point i like it.
