iPhone, Android users worry about security, but don't know what to do

iOS and Android users don't seem to share the same views on much when it comes to the mobile space, but they both appear to have concerns about security threats to their devices. According to recent data from the NPD Group, users of both platforms are worried about having their credit card info stolen, device theft, hackers accessing personal information, harmful apps, and unwanted location tracking. Very few have chosen to do anything besides worry, however.
