Okay, I’ve had ICS installed for 24 hours now.
I like it!!!
I did want to make a comment on the face to unlock feature for unlocking the phone. It works really well in good light, but not in poor lighting. It also works whether you have glasses on or not, which is handy as I don’t always wear my glasses.
It takes about a second to recognise you and unlock. If it doesn’t know who you are or can’t make out a face, then it switches to a graphic combination unlock screen like normal.
