Deployment failed because of an internal error: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

hi guys,

My application was never installed to my samsung devices at all.
Why I was using VS and Xamarin Studio always popup this dialog and can't be installed to the device at all.

Deployment failed because of an internal error: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]
