    Check for any features under Smartlock been activated unknowingly ( especially the on body sensor one) and disable them accordingly.

    for me Faceunlock works well ...does not open until filled face is shown with eyes open...it's secured for me ..

    No it's not.

    I tried this on very first day as there are kids in my home who may use my phone during my sleep.

    but it's simply does not unlock, not even in semi closed eyes.

    Sometimes I wonder how you guys are finding bugs and I am not

    The team are looking into the face paper cut out unlock, which a guy did post on YouTube.
    whether that's actually real or not I can't confirm.

    it'd be so easy to take that for likes etc.

    in regards to anything else, you can take a picture of your face and display It on another screen in hopes to unlock it, but it won't work.

    it's key to note that only high end windows 10 phones used IR with their iris unlocks to scan eyes so it has a fool proof security there.
    face unlocks however on every other phone are just point references of the face, so eye detail is low and the camera is just looking for points of contrast (in black and white) to unlock the face.


    I've just reset my face scan and can confirm if the data is scanned with your eyes closed or squinted, it can unlock the phone.

    so I highly advise you to delete your face data and try again.
    if you feel that your eyes could be misinterpreted as closed based on your own facial structure.

    take the face data info at 45 degrees off of a window in your best side, if it's super sunny out redirect the light using blinds, or a cloudy day, or if the window has a net curtain that diffuses light, that'll work too.

    It is very simple to test.... Hold your phone in front of your face, test with eyes open to make sure it can read your face, then relock the device and then press power button to wake the screen, hold in same position for a few seconds and it will unlock the phone. Works all the time.

    If you have your eyes closed how do you know?? Don't you need to see anyway?

    I hold it up to my face with closed eyes, press the power button and then there's the unlock sound effect. then I turn the phone sideways so that the front cam doesn't see my face then I open my eyes and look at the screen. Don't worry I am not retarded lol

    that made me laugh.

    you can also force pocket mode by hovering your thumb over the camera, of course in this case turning phone is just as easy

    It doesn't bother me, since I just received face unlock with the OTA I was trying to how can it be bypassed so I did this experiment with my friend who has same hair style and beard and we tried to fool it but it didn't (I tried this becuase smart unlock on my S4 was fooled this way).
    2) Doesn't unlock with photos and videos.
    3)Doesn't open with closed eyes but just for fun I tried opening with one eye and it unlocked.
    Overall quite impressed with face unlock but this is a bit concerning since someome can forcefully open one eye and get into your phone but since 3T has a front fp sensor I was just using face unlock for fun so not much a problem for me.
    TLDR:Not a problem.

    That's good to know actually,
    I've come from using iris scanning which was far more secure than the face unlock and I've yet to be able to fool it either.

    I haven't been as extensive as yourself, but it certainly settles my concerns for the time bring
