Would someone please help this old man out and guide me in lowering and/or turning off the three LED touch buttons at the bottom of my DNA screen. I am a night time reader (using Calibre Companion with paid version of Aldiko Reader) and these three LEDs are burning my eyes out. I have tried the following screen dimmer apps with no luck: Night Mode and Screen Dimmer. I appreciate anyone's help on this and I do realize that I may be missing a completely apparent setting that does this.
