How to remove dummy account from android? When I go to factory reset my android device I found a "dummyaccount" on my device.

Does anyone know what this "dummyaccount" is and how can i permanently remove it from my device?
The answer is within this article:


  Add the Account Required by the Framework
  
  The sync adapter framework requires each sync adapter to have an
  account type. You declared the account type value in the section Add
  the Authenticator Metadata File. Now you have to set up this account
  type in the Android system. To set up the account type, add a dummy
  account that uses the account type by calling addAccountExplicitly().


So the reason for this account was probably some app, that needed its local database to be synchronized with server using a sync adapter. This app has created account called dummyaccount. Some tricks exist to hide this account from the account list in Settings.
