How to Disable Contacts Found in Mail in iOS
The latest versions of iOS support a feature which scans a users mailboxes for contacts and contact information. While this feature can be really helpful in potentially identifying callers and contacts, it can also lead to erroneous information being filled in to your address book contact cards, erroneous assumptions about callers, and even improper suggestions in the Mail app. For example, perhaps you’ve opened someones contact card and discovered an incorrect and random entry for email or phone with a “(found in Mail)” text appended next to it – that’s this iOS feature in action.
For users of iPhone and iPad who have discovered this feature and find it to be annoying or inaccurate, or perhaps for those who just don’t like the privacy ideas behind suggesting and autofilling in contact information based on scanning email on the same device, you can disable this feature in iOS completely.
