Unable to install downloaded apk, can't press install button
need some advice here.
I've been installing apk file from dropbox for testing purpose for few weeks. Occasionally I couldn't press the install button (on the install screen), but it resolved itself after few attempts.
However, it doesn't seem to work any more. I just can't press the install button, but OK for the Cancel button. I've tried restarting with/without pulling out the battery. It still doesn't work.
Have googled the issue, only able to find this thread
