Almost everyone a phone now, even I, a seventy – year – old grandma asked dad for him to purchase a cell phone, my grandma have no culture, so there is no way to set the password for him, but I heard that you can set the face recognition of Singapore, as long as grandma take a look at the phone’s screen, cell phone can unlock, grandma was very happy to hear that, said the mobile phone that she can also use a password. I told my grandma said, now the fast development of science and technology, you can set the face recognition Singapore convenient for many people. My dad said my grandmother, so big age, set the password is very troublesome, not a child again. My grandma is very fashionable mobile phone looked at it said, you see, my password is to look at my cell phone. With my father and I burst out laughing.
