I need to address this use case.
A friend, acquaintance or a stranger on a train requests my phone to make a call. I don't mind acceding to the request, but I would like to restrict access to what the user could do on the phone. So I switch to guest user profile or a custom profile created for this purpose.
Essentially she should be able to make a call or use a default app. She should not be able to view my contacts, call history or SMS history or install and use any new apps.
This could be partially achieved by using the guest profile. However it is noted that a guest user can still access my call history.
Could we add a configuration to the guest user, such that the call history is limited to only calls made from or recd to that profile.
Alternatively, we could create a new profile specifically for this purpose, by enabling phone calls, and disabling app installs. But the issue of access to call & SMS history still persists.
