I don't know if anyone else has had this issue with downloading apk files from unknown sources.
OK so whenever I download any apk from sources other than the playstore. I know I should check the 'download from unknown sources' in the security section in the settings menu.
However when I press onto the apk and the installation manager asks to either 'install' or 'cancel' I try to press install but it doesn't work... Like no reaction on the screen... It's as if the screen is locked. But when I press the cancel button it works N hence apk isn't installed....
Does anyone have any solutions to this please let me know.
I have attached a screenshot of which button doesn't work.
Your help would be much appreciated
