    CTIA or OMTP Standard?

    Hello! I am using a Xiaomi Redmi Note 4. Since I would like to buy a Lavalier Microphone, I need to know which kind of TRRS Standard is used on Xiaomi Phones: CTIA or OMTP? Also I need to know whether the Xiaomi TRRS Socket provides Power to the Mic? Thanks for your help!
