Galaxy Nexus Android issue: After downloading the CE program for Android, I'm am asked to install the CE helper app. Tapping this, I am informed that I must go to my settings to allow for non-App Marketplace apps to be installed. At this point, the CE helper install screen continues to pop up, essentially blocking all other activity on the phone. Signing in or signing out makes no difference. Going to settings takes me back to the CE helper install screen, as does every other attempted action, or simply waiting 3 seconds. I'd like to have the app installed, obviously, but I can't do that or anything else with the phone until this gets solved.
