Hello,

In android, they don't store the contact in a file or vCard. This information is saved inside a DB and you only can access this with superuser privileges.

We made an app to manage the contacts information, like backup and restore. Our dev team uses this intent to manage the contact information:

I hope this information can help you, I work with MC for some long time and if you can explain in more details of your need maybe I can help!

Best Regards
