I'm not vouching for the efficacy of the blue light element, but this immediately solved my Galaxy S5's blinking screen issue when no other adjustment worked. Mildly technical explanation: Because the CPU and GPU would constantly trade handling low light screen elements following a system update about a year ago, the screen would brightly flicker green. Since this app forces GPU handling of screen brightness, it solves the issue completely (even when similar apps failed).
Before last update was working fine but now Auto On Off doesn't work.
Lots of personalized options and very easy to use
