See that probably explains it, perhaps that lockscreen somehow called the multitasking activity from Google and not the one defined as default on the phone, and there you had the google multitasking screen showing up!
It happened on my previous phone when I tried Nova Launcher, which had by default a shortcut on the homescreen to the camera activity - only, that called the default google (part of Gallery.apk) camera and not the Fujitsu camera, so I was able to use either camera.
