I give you an example the awesomeness of Jelly Bean here.
Face unlock feature was introduced few months ago. It was more a gimmick than a daily-use feature.
The reason was that it worked 70% of the time in good lighting, and 0% in abnormal lighting.
Even when it worked, it usually took 4 seconds to response. So I just used the pattern unlock which took 2 to 3 seconds and guaranteed unlock.
Now, with Samsung S3 ICS, the face unlock is faster by having a faster cpu. About 2 seconds, which is pretty good, but accuracy didn't change.
With Jelly Bean, it's AMAZING. It's literally less than 1 second; it finished unlock before you can even see your face on the screen, and you are already at the homescreen. Also, the accuracy is almost perfect. I only have one didn't unlock right away out of 100s. It even works in dark light, different angles, with/without glasses, or looking else where.
That's just one example, and that's for S3. So I dont know how good or bad on S2.
