Why will NO .apk files sideload?

[Skydog#AC]

And, yes, "Unknown Sources" IS checked/enabled in app settings.

Whenever I sideload an apk for installation, the 'install' button is completely unresponsive -- only 'cancel' is active. What is the problem? Of all my other Android phones and tablets I have never once had a problem -- until now, with my Maxx. Nothing will install, including apks of backed-up apps already on the phone.

What am I missing? I am beyond frustrated.

Hmmm all mine install just fine. I had one that did not want to install correctly and thats because I was trying to install a non-qhd app. Once I found the right apk everything was golden. You may have to hard reset. I know its not the solution you are looking for but may be your best bet. I used ES File explorer, im non-rooted.

Oh, the dreaded hard reset. If it comes to that perhaps I'll wait for ICS to arrive. I just wish I knew why this is occuring.

Long shot, but are you using Screen Filter by Haxor? Oddly, if you dim the screen with it, the install button becomes unresponsive when trying to install apks.

Thank you, B.Diddy -- you are brilliant! I am not using Screen Filter but I do have Screen Adjuster (for RGB color and contrast) installed and it appears to be the culprit.

BTW, for anyone reading this, ScreenDim is far superior to Screen Filter, IMHO. ScreenDim is highly customizable, has five editable presets and, most important, does not interfere with sideloading apks.

I do have screen filter installed but it is not running. I switched it back from screen adjuster because screen filter can be put just about anywhere without using a widget. Bummer.

Just experienced the same thing using Twilight on my htc one m8. That is a really strange side effect of dimming the screen.

FYI - The same thing happened to me on my Galaxy Note 3 running Lollipop today all because I was running the brightness app Lux Dashboard.... go figure...

Same problem here. Disabled Twilight, no luck.

Turns out it was Copy Bubble blocking it. Disabled that and now it's fine.
