nfc tag read even when lockscreen on

[Zeench]

Is it possible to let automatic read nfc tags while my Smartphone is locked?

Hi,

Unfortunately most devices turn off NFC when the screen is locked or turned off and to my knowledge there's no way for regular apps to change this.
When I recall correctly then there were some Xposed modules available to modify the ROM so NFC also works when the device is locked. I've never tested how well the modules work but you should find more information by googling for 'NFC xposed lock'.

Regards,
Martin

already found that xposed framework but that requires a rooted smartphone.
But I dont want to root it
