[Oxygen OS 9.0.2] My friend unlocked my phone with his face

    One of my friends found my phone while I was in the bathroom.
    He made many pictures of himself.

    After that he accidentally swipe from the bottom and the gestures automatically tried to Face Unlock my OP6.

    He made faces and it worked. My phone unlocked. He created a photo about my unlocked phone and he showed it to me.

    There is just few similarities between us: We have stubble, same age. But he is taller, different hair.

    How is it possible?

    Are you aware that even One Plus told that Face Unlock wasn't secure ?

    faceunlock is not safe in OnePlus!!!
    if you value your privacy, disable it. its just for convenience purpose, OnePlus has already declared it.

    Anyone can take pics with phone locked. You don't need any finger print or face unlock. You can swipe for camera from lock screen. And also by double pressing the power button.

    Are you sure it wasn't just that?

    Yes I know that, but I did not see that coming. It just scared me that this is possible.
    I removed face unlock right now.


    I am sure yes. He is unlocked my phone and he can see everything if he want.
    I dont know how is it even possible.

    Just another question. Do you have any smart lock features activated? Because it may be that actually unlocking the device.

    Go to settings > security & Lock screen > smart lock and turn off all of them to see if the same thing happens.

    Nothing else. No unknow fingerprint data, no smart lock.

    Well, if all is turned off, than I guess you did find someone with very similar face with you. :sweatsmile:

    Have you tried adding your face again to see if it changes anything? Maybe doing it with better lighting to see if can capture better the details.

    It was the better lightning option. :sweatsmile:
    Earlier nobody can unlock my phone, because it was a low light face data. The unlocking was slow even with my face because of that.

    But I will try it again just to see if it is working or not.
    Before I removed Face Unlock he can unlock my phone in low light in 5-10%.

    Facial recognition has always been known that it is not 100% safe, if you need more security use other unlocking systems
