Cleanup Wizard in Contacts

I have written on my mild obsession with keeping my contacts pristine in the past and I wanted to share a recent find that does not seem to be documented by others.

The most recent releases of Contacts for Android includes a "Cleanup Wizard" that among other things will find contact details in email signatures and merge them to your contacts. Fullcontact offers this same feature on its paid tiers, but it would be nice to see the difference in the intelligent methods each apply.

If you are on Android, you may still be using the stock contacts app that came with your phone, but most devices can also use the latest app by Google without problems.

On the left top menu look for suggestions. The two options I have seen are:

"Add details from Gmail" seen here, and "Add people you contact often" that is similar to features available on desktop for years.

If you know any cool tricks to keep your contacts perfect please share in the comments.
