Could be it's because f.lux dims white ? I find screens with white very white (for a lack of better word) like Apple's, oled screen etc. hard to use, I can't focus when the background is white and generally try to reduce the output or dim screen. My desktop screen's brightness level is at 0, except when there's a lot of sun then I crank it to 30% max. I have an old dying saartphone and new ones are not as comfortable and I blame the screen. I wish they made another e-ink phone.
