why does face recognition ask me to remove glasses

[mcp111]

When I've told it that I always wear glasses why does it ask me to remove the glasses to complete setup?

[Vijay10]

you told you always wear glasses so only it records your face with and without glasses then only it can able to unlock if you are not wearing glasses also

[mcp111]

so why does it sometimes fail with no match error even when I'm looking straight at the phone

[Vijay10]

it is not that much good in recognation it recognises better in outdoor conditions

[mcp111]

will face recognition work if I have a small hurt on my face covered by plaster

[Vijay10]

i think so
