Chosen Solution

Hey there, For some reason I cannot install apps from unknown sources. Yes, I have enabled access to install them, but when I have to choose between ‘cancel’ and ‘install’, only the cancel button works. The install button does not respond at all. Have tried to reboot it, also tried other APK files. Would be nice if someone could help me out!

You can always use another program to install apks beside the default one. Try a 3rd part installer such as ES File Explorer or ASUS file manager.
