Here's what I need. I run a business, I use my personal Android phone (Samsung Galaxy S8) for 100% of my calls. It's not a problem. But I have a lot of clients whose numbers I don't have memorized. I could put a hundred contacts in my personal phone so I would know who's calling, but, I don't want to fill up my phone's contact list with people I only talk to occasionally.

When I look at my contact list, I want to see my friends and family only. Is there an app that will handle sort of a 'secondary phonebook' with business contacts only, that will still work with caller ID?

And if you are going to comment 'you need a second phone for business stuff', don't bother. That's not what I want to do, and that's not what I'm asking. This is a question about whether there is a particular Android app that will solve my problem (or an Android setting), not anything else.

    1. Create a group , say business as explained here . Add members as explained 2. Hide / unhide contacts as explained here - there would be minor variations as it is for a different device. 3. Hide business group to only see family / friends, unhide when you want to contact them – beeshyams Jul 20 '17 at 13:22

I have saved separate phone contact lists as vCard files-one for business and another for private use. another for frequently dialed numbers (hybrid of both pvt+biz). It is tedious but depending on my need i load(import) one from my collections above. Hope this method helps.


I had the same issue and couldn't find an app to fix it so I decided to create one. You can check it out Secondary Contacts

It's an entirely separate contacts list that can't be read by other apps. Has caller ID too and you can import/export contacts to and from the main contacts app


You can use the Google contacts app with two Google accounts and swap between the accounts easily as necessary. (Here is a link to the Google contacts app.) Or if you're using a Galaxy S8, you can have separate contacts in the secure folder.
