1. Finally, a blue light filter and screen darkener that you CAN TURN OFF! Why the heck none of the others let you do that is beyond me, but I will never use an app that demands a constant background process.
2. My one big gripe with it is that when you screenshot anything with the color filter active, the screenshot takes on a much darker version of the color filter I'm using, which totally distorts the image.
3. But if author could find out what's going on it'd be great, because the app still doesn't work as it should.I bought the Pro version.
4. You can set it on in Accessibility so it doesn't make apps inaccessible on screen, but very shortly after it turns itself off and you get a bright screen again.
5. Drives me nuts!Experience has been great until Aug 2021, but now, some app buttons do not respond anymore when the Darker filter is applied.
6. It darkens only a portion of the screen on the phone (leaving the top and bottom unchanged) and has no option for external display connected via Samsung DEX.
7. I tried to turn down the brightness but the screen was still very bright.
8. An internet search led me to turning off the darker setting, and voila: all of my "broken" apps starting working again.
9. Unfortuante, because Darker is the most light weight, unobtrusive filter out there.This app hasn't worked for awhile.
10. Not sure what happened, but it took a while to figure out what was going on: some of the newer updated apps (like my banking app, and others) suddenly stopped working.
11. I replaced my old bad screen with a new one and ever since, I can't control my phone's backlight.
