Hacker's Keyboard is ignored now, it tells me I have to unlock the phone? Somehow my phone is not showing me my Hacker's Keyboard anymore. It's saying that it could send all the info I type to a 3rd party (which is technically correct, I would imagine...)

It used to work, I installed a new app. and after about a month it managed to prevent the keyboard from showing up. I went to the settings and turned the keyboard back on (ah! it looks like it was turned off on me...) That step told me that it would work only if I were to unlock my phone and reboot.

So how do I do that and is that specific to just this app or would it allow (unlock) any app. from doing what it wants? Is Android that lame?
Well! I'm not sure why, but somehow my Default Keyboard setup was back to the Samsung keyboard (the default). So I guess there was a new version which was updated and after updating, the Default keyboard switch was back to the default.

Editing that one setting and the Hacker's Keyboard was back in business. 

The selection of the Default Keyboard on my phone is available from "Settings" > "General Management" > "Language and Input"
