@johnyma22 Yes, I have downloaded and reinstalled several times from the Google Play Store.

I'm having the same issue with my Samsung Note II, Android 4.1.2 The unlock App works fine but can not get the control App to work... I click on the options but nothing happens. Phone does not lock up. So I am not able to register to use the unlock app. I was reading there is a beta app to download but do not see where to get that app. any help would be appreciated. Also, I do have the NFC on and have written to tags and they work.
