How do I separate contacts from work and personal Google accounts? I have two Google accounts, one for work and a personal one for my Android phone.

I have both accounts synced to my phone because I often have work to do on the road. I recently noticed while logged in to my work account in GMail that all of my personal account's phone contacts appear in my work account's contacts. I never asked to have the contact lists merged together, nor did I add one to the other.

They may have been logged in together on a computer at one point before, but I can't remember. My personal account is not currently logged in on the same computer as the work account, so I'll be able to delete them from the list now. I just don't want this to happen again.

Is there a setting to suppress this behavior?
You can download Google Contacts app.

When you want to switch accounts, just tap the profile picture thumbnail on the top right, and select the desired account.



You can select either Google account, or view an unified list (for whatever reason, or if you later change your mind)

When adding a new contact, make sure that you are selecting the correct account. (you can view it at the top as Save to)

Of course, both accounts need to be connected to the device, and sync should be enabled.

And if you mixed up your contacts...

From your comment:


  [...] it seems that the phone's contacts are syncing to both accounts. [...]


You can switch accounts to confirm, and if it happened, you may want to delete the duplicated contacts, and then switch to the other account and move your contacts to the right place.


Select the contacts you want to move (tap and hold)
Press the menu button (or the three dot menu at the top)
Select your desired action:


Select all
Delete
Move to another account
Add label (Group using tags)
