Check if you have activated any screen filters. Disable it. It should work fine.

Can u explain how to deactivate screen filters

I had this same trouble with Amazon Appstore. It turned out that my 'nightmode' app used a screen filter, and was preventing me from pressing the install button!

They are not activated unless you install some app (like "Night mode", "Screen filter").

Usually, there will be a notification in notification bar that the app is runnign. You can open the app and disable that mode.

I don't know what "pradeeprk4" meant by screenfilter

go to settings > apps > all > look for any app that you want to uninstall

It definitely is a screen filter. it's in the software, some buttons get blocked by the changes the app makes to the screen.   As I already said, I had this exact problem, and it was caused by the screen filter used by nightmode.

which screen filter app?

[bigf28]

that application: Screen Filter

@ianpatrocinio If you have "Screen Filter" installed disable it when you want to install something
