For that we are going to "Settings> Security> Device Administrators" or "Settings> Security> Device Administrators" seek SystemPatch (yes, it's going to be there), and deselect. Confirm the action in the message below (the "Disable")

For phone my mother, I had this installed, even the CM Security or Avast detected it as a virus (it probably is, but it is an application annoyed)
ATTENTION! One of our readers we leave this observation (Montiel Lagartomax Thanks for the tip): "Excellent Very useful solution would not let me uninstall, the funny thing is that I did not let off the administrator, until you turn off the device and then we could! "
