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?

  • Is there any other gmail account signed in the device? – Rajendran Nadar Sep 11 '17 at 17:31
  • In what state is the phone? Why do you want to factory reset it? What issues are you experiencing? – esQmo_ Sep 11 '17 at 17:32

  • You probably have been infected by some malwares. Have you noticed weird/unusual behavior? – esQmo_ Sep 11 '17 at 17:36

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.
