Good thing Samsung doesn't make the phones racist. I feel like the face recognition technology is still to young as you can fake it with a picture. It probably will take a few years before they can make it legit and efficient like we see in movies. First they need to fix the self camera, not to start a fan war but honestly the self camera on my iPod 4g is much better than the one on my phone, not sure if its just my phone which came with a faulty self cam lens but when I use it the image is just very dim and makes for a bad picture. My iPod in the other hand isn't high tech but has a much better self can.

Anyways improve the self can with tech that can distinguish between real and pictures and software that can recognize facial features deeply as then even twins can't mess with unlocking the other's phone (my silly friends who are twins tried it and it unlocks with the other's face). This way way out in the future but cams that can even do face unlock in pitch dark. Also I feel like face unlock needs to speed up as the speed isn't practical, I know it looks super cool in movies ex special ones that scans the eyes but isn't practical in times of emergency. You need to whip your phone out to take a video of dude having his face chewed off (for evidence of course), or take a picture really quick of a UFO, call 911 because of an accident, you wouldn't want to be standing there finding the right angle while the poor dude is bleeding or the UFO gone. Or just something simple, your jogging and you wanna unlock the phone to change track, your gonna need to stop, probably whip the sweat off and try and unlock it.

I am aware that there is a password feature but what's the point of using the face unlock when you just result to keying in a code. In my point of view, not hating on face unlock but no matter what security you use there is some kinda hook to it, passwords and patterns can be seen while keying in, face unlock can be fooled by twins or a picture of the face to unlock and isn't fast enough. Things like finger scanner. While your asleep someone could use your finger and unlock your phone if your a heavy sleeper and voice recognition can be fooled by audio recording of you or by pro mimic people, also voice recognition can't be used in loud places.

Don't know if there is other form of security, the recent windows 8 unlock where you select 3 parts of a picture to unlock can also be seen by someone else like patterns and passwords and isn't fast enough like face unlock. In my opinion though all security has a catch to it for mobile and tablets and laptops the best is finger print scanner, sure your at risk of your device being unlocked while your asleep but the chances of that is pretty low unless you are high on the drug that doctors give you to make pain numb. Also its the fastest unlock (based of device specs) compared to anything. And for maybe desktops use face unlock as desktops are in only one place and used in bright light condition mostly but if not, its a desktop how hard is it to build flash onto the front next to the cam.

I don't know that's jusy my opinion, sorry for the crazy long post, not trying to change the topic of face unlock but just gave you guys something to think about. NOW DISCUSS!
