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.
Amazing idea love that I can throw this on and keep browsing my phone in the dark without feeling blinded by light. sliding scale is a nice touch, although I wish the ad portion would stop popping up. sometimes the filter unapplies itself for a second which is always a shock but then goes right back on
Asus Nexus 7 Tablet I could NOT download apps or updates from Amazon Appstore until I disabled Blue light Filter on my Nexus 7 Tablet. Drove me nuts for the longest time till I read "noachk's" rating, thanks.
Ads have ruined this app And why does it need access to App history?! It's a shame because its an effective filter but the ads obscure top part of screen and it now has a dodgy feel to it. Have moved to an alternative.
Paid version includes a widget to toggle, updated to 5star, very happy with this app.
Very effective This simple app is great for reducing glare. Does the one thing extremely well - that's it! Highly recommended.
