Quote:A new policy implemented by Google for Android apps brings tighter controls for SMS and call logs, technically enforcing a new limitation of the use of services like digital assistants on the platform.
 
According to Google itself, access for call logs and SMS should only be required when it’s absolutely necessary for the app’s core functionality, which Google defines as explained below:
 
“Core functionality is defined as the main purpose of the app. It's the feature most prominently documented and promoted in the app’s description; no other feature is more central to the app’s functionality. If this feature isn't provided, the app is “broken” or rendered unusable (i.e., app is deprived of its primary functionality and will not perform as a user would expect).”
 
These changes mean applications like Microsoft Launcher can now receive your permission to access calls and texts, but at the same time, to also enable Cortana to read this data.
