Hello, I'm trying to detect Mifare Ultralight card when backlight is off but nothing happened.
I've tried on several devices (9360, 9900, 9790) with latest OS 184.108.40.2065 but it doesn't works.
I've seen an option "allow NFC Card Transaction" :
- When Locked or Backlight is Off
- When powered off
But these options not seems to be take in considerations, maybe it's for other NFC Services?
How can I Do?

Same problem here.
I solved it by implementing a Timer that keeps the light on, using Backlight.enable.
I wish there were a cleaner method via API to listen for NFC without caring about backlight.
