So if you haven’t realized from my posts by now, I like to experiment with Android from time to time and today was one of those more special days. While poking around FaceLock.apk, which I decompiled with apktool, I opened this. The screenshot above portrays a file “arrays.xml,” which contains what looks like phrases to be presented on the lock screen when a user’s face is not recognized. As those of you fortunate enough to run ICS know, currently an unrecognized face only returns “Sorry, don’t recognize you” or in some cases “Couldn’t find a face.” Aside from a different spelling of “recognize,” the list above also offers a substantially more varied output. So what is the meaning of this? I supposed it could be simply leftovers, never scrapped before release, or, letting my optimistic imagination run just a little bit, perhaps this is some preliminary work towards a future update; Majel maybe? It’s a stretch, but the varied and pretty casual responses seem more AI like to me. In any case, an interesting little something indeed.
