Your device’s contacts list holds a treasure trove of sensitive data that many apps want to get their hands on. Fortunately, Android’s permissions system prevents apps from accessing your contacts without your knowledge. Unfortunately, it’s an all-or-nothing system: You either grant an app access to all your contacts or none of them.
This is highly problematic because it forces you to grant many apps full access to your contacts even if they don’t need it. Next year’s Android 17 update could tackle this problem by introducing a system Contacts Picker tool that allows you to select specific contacts to share with an app, rather than giving it access to your entire contacts list.
