How can I change the brightness of the light ring or turn it off?

1. Tap on the “Devices” symbol in the menu bar.
2. Select the desired ekey fingerprint scanner.
3. Tap on “Signaling”.
4. Set the brightness slider of the standby lighting to the desired value. If you want to turn off the standby lighting completely, set the brightness slider to 0%. This only turns off the standby lighting; all other signals remain unchanged.
