I know it was wierd, but that was the only setting I changed and screen stayed a dark bluish color, quit when I put backlight back on.

Anyway, kept researching and found program on xda called LUMOS that I have downloaded - looks great and might be the answer. I ran calibration, need to read and follow directions, but put in window for direct sunlight, ran up to 1446 for high lumens.

It is adjusting between window light vs room light, auto back light under Power is off.

Spending the afternoon outside, will see how this works and report back. Might be the answer.
