So, since Face Unlock came out initially, I was all into it. It was very cool and couldn't wait to show it off to my friends who either didn't have Androids or their Android phones didn't have ICS available yet. I've probably used it majority of the times when unlocking my phone.
However, I have to say that, although I still have it enabled, I rarely use it anymore. I've made the habit of repeatedly tapping the bottom of the screen now to initiate the pattern unlock to go straight to the secondary unlock method. For me, Face Unlock is still cool, but I find it much faster to swipe my hand in a quick pattern and not have to worry about whether or not the phone's going to have problems detecting my face.
I am curious to know how many of you still actually use Face Unlock, and if so, do you ever experience lags and/or experience the camera not recognizing you?
