Face Unlock not working on Nexus 7
I have set up face unlock on my Nexus 7 tablet and all worked fine for three days. Then it suddenly stopped working and the feature didn't come up every time for me. The screen just remains black upon and it never attempts to recognize my face.
In my opinion, Face Unlock doesn't work very well on Nexus 7. The front camera tends to pick up dust and oils from your hands, and that will be defeated to take a picture of your face. So you need to keep the camera lens very clean. I'd recommend using pattern lock or a password.
