Example: I download an .apk from the internet to my SD card and when I try to install it, the install button doesn't work, only the cancel button works. I then reboot my phone and once it's back up I am able to install the .apk. I would need to reboot again if I wanted to install another .apk file.
I have search and found some solutions but none of them have worked.
How can I fix this issue.
