OK got the fix for you, or more of a "work around".
To start with the latest Freedi downloader app works fine to download on Android 4.2 and 4.3 and 4.4 of kitkat. The problem is the "menu" was no more accessible in the newer Android devices that got rid of the dedicated menu button.
I recently got the Galaxy 12.2 note pro and the Freedi downloader became useless if you couldn't do a search to find the youtube video you wanted to download.
After playing with the settings, I found a way to access the menu, here is how.
Go to settings> "Device" tab> Accessibility> mobility> Assistant menu>turn the switch to "on".
That's it, now you will see a little square showing on all apps that has several choices one of them is the "menu" choice and voila you're back in business.
Hope that helps. Have fun.
