No issues for me also. Usually these kind of glitches happens after an OTA update. Try to install the firmware through smart switch or Odin

Hello friends,
finally I discovered that this is not an issue, this is an function on the new android Pie, The system turn of this function when I choose sunset to sunrise option when I'm using power saving mode, because it turn off using location service on the background, but when I turn on the power save mode off the blue light filter "sunset to sunrise" work properly 👍.
