Answer to "How do I remove Samsungs Live Demo Unit Software?"Password for phones from Sam's Club is "Walton". It works, and although I understand I can't use cellular, this is becoming less of an issue everyday, as I live in a city and everywhere there are hotspots and many apps to take advantage if free WiFi calling and texting. .....BUT...The software demo keeps coming back intrusively. And it won't update the security policy so that popup is a constant problem. On the good side, the phone was a demo that I bought off a dude on the street, for a very reasonable price. I'm sure he came on it through honest means because he told me so repeatedly.
