    Galaxy s2 v7.0. Cannot set app defaults eg. default PDF so i can view PDF sent via email. When I click on adobe pdf pic in email, I get the msg 'cannot find app to open the file'. It also opens in my 'print screen' if I hit 'save' which is annoying. When I go to Set App Defaults, the 'clear defaults' button is always greyed out. HELP!!

    That's because there's no app to open an app, which is what you're trying to do. Try Default App Manager instead. It has a setting for the default .pdf app. (It's easier than downloading a .pdf file, opening it, then choosing Always. It takes you to the same process, but without having to have a .pdf file to trigger it.)

    Then when you click on a /pdf file, Adobe Reader will open with the pdf file in it.

    Welcome to Android Central! PDFs should be readable using Google Drive/Google Docs -- do you have them installed? Or you could install something simple like Google PDF Viewer.
