Hi,   I recently bought a Galaxy Tab A7, to read pdf files. I keep getting awful migraines though. Bright lights, flashing, and certain animation all trigger my migraines.   So far I've minimized brightness, and disabled adaptive brightness, in Settings > Display, and tried various dimming and screen-filtering apps. These help some places, but not others.   I've also set remove animations in Settings > Accessibility > Visibility enhancement. This doesn't stop blinking cursors. Using Night Mode greatly reduces the contrast of blinking cursors, though, so that's something.   I've tried Orion Viewer for minimal animation, as well as Moon+ and Librera.   I've noticed that (a) it's a lot harder to focus on text than with e-ink displays, and (b) it's a lot worse looking at text with lighter backgrounds than text with darker backgrounds on the glowing display.   Any idea if this is something inherent in the glowing displays, or specific to the Galaxy Tab A series? I've looked, and it's supposed to have low minimum brightness, no pulse-width modulation, etc. so it should be better than others.   Any idea what could help, short of returning the device and trying to find an e-ink alternative with suitable screen size, pdf support, etc.? ...
