My dad used to have trouble with Enternet Explorer. Mainly, his sister in law would come visit, play a bunch of Flash games, and then his computer wouldn't work right anymore. So, I explained what Chrome was ("what's a browser?), installed an adblocker, removed the shortcut for Enternet Explorer, and replaced it with Chrome. He would say he understood he needed to click the Chrome logo and the internet would still be available like he was used to. When I would return days or weeks later, I would notice that Chrome was still there but IE had crept back somehow and he was using it. I think a similar pattern happens with phones. Whatever is baked in, gets used by the average user, regardless of how bad it sucks to someone in the know.
