On the phone plug there should be 3 separate contacts. At the end furthest from the cord will be the tip. Next to the base of the plug will be the sleeve. And in between the two contacts will be a small isolated ring. Tip and ring
If this contact is missing then focus will always be activated while the remote release cord is connected.
The above assumes you release has a 2 step release of focus and shutter release.
