It interfers with some operations on the phone screen. Amazon apps could not be updated until I disabled it. sometimes answering calls is made impossible due to the screen not responding well with the filter (without it there is no problem). Galaxy Note 3.
Random deactivation lately. Also, this app really needs a widget, the notification idea is clever but not my cup of tea.
Man it has a hug problem the Super Amoled display on my note 4 doesn't show black any more even when I set it at 25%. This grey greenish color has taken it's place I don't know if it should do that because it literally made everything look dead
Excellent for viewing in the dark but... Keeps on crashing while I'm browsing. When I restart the app, it went haywire; enabling disabling the filter a couple of times b4 finally opening the settings. Happened frequently, more like everytime I used it for long duration. Pls fix. Luv the func but the crashing really bugs my eyes.
So far so good. I have been using this app for the past two or three weeks at night, and so far I have noticed less eye strain, and avoided headaches due to a bright screen in the dark. As far as battery life goes, I haven't noticed any drastic issues, but again I've only been using this a night, so not necessarily long extended periods. Also, in terms of the app being in the notification bar, I think its worth noting that you can turn that feature off in the app settings which I have found to be very useful.
Nagware with notifications that block the top part of all apps! I love the functionality, but the nags to install other software that require me to acknowledge an intrusive pop-up that blocks the top menu area of all apps is beyond annoying. There is a built in notification feature in Android for just this purpose. Keep nagging with these types of pop ups, and I'm uninstalling.
