When ever I try to install an application (i.e. angry birds.apk - freedom.apk - Clash of Clans.apk or any other application that requires the install page, except for the play store) I am not able to click on the install button but able to click the cancel button. The install button won't even "press in"
Does anyone have an idea why I cannot click on the install button? I have done a little research and says to turn off "screen filter" or "twilight" however, I do not have those applications causing the problem to be very annoying and unable to solve.
- thanks -
