Toggle and Auto Both Work This tool works exactly as described. After following the instructions  it enables the night mode options in the system UI tuner and displays the quick settings toggle. Also  despite what others have said  the automatic function within night mode works too. I had to restart my phone for this though. Also  if you're used to Twilight  you may think the automatic isn't working because it comes on much later than the Twilight default... And Google has not provided the option to adjust the timing (or the colour)
