How to programmatically make NFC work when is screen off
Question
Is it possible to enable or force NFC work while screen is off?
There are some ways like downloading a nfc enabler apk or root the device but I want to make it in my application, not using another application.

No, there is no way to do this. NFC is off by design when the screen is off, mainly to safe power.

You can definitely do it provided you have access to the firmware code. Once you enable it in firmware, you need to define your flag in NFCService and enable NFC working even when screen is off. I have seen few devices having NFC working even when powered off but that is card emulation mode. So it is possible.
