iphonex and face id
i have a iphonex 256gb i set my face for the face id. i scanned my dad's face and it didnt open so i use mine to unlock i did this a few times and surprisingly now me and my dad can both unlock the phone with face id ??? can any one tell me what is the problem with the bionic "learning" function
ps: we dont look alike
