Delete an account from Android without affecting the apps related to it I have three accounts in my Android phone. I have apps installed in the phone via them. 
Now I want to delete one of the account (NOT primary) but don't want to lose the apps related to them.

Is there a way to do that?

Or if I can move my apps from one account to another, so that after doing this I can delete the second account?
Deleting a secondary account won't delete the already installed apps associated with the account, AFAIK.  However, that's a loophole that Google might plug in the future.

It's not possible to move apps from one account to another.
