In a recent Lookout survey of more than 1,000 smartphone owners, 52% of those who claimed to be security savvy didn't read privacy policies before downloading mobile apps, 34% didn't set a PIN or passcode on their phones, and 35% downloaded mobile apps from unofficial marketplaces. The survey also found that those who claim to be privacy experts are most likely to partake in risky mobile behavior, like connecting their smartphones to unsecured public Wi-Fi networks, visiting unfamiliar sites on their phones, and plugging their phones into public charging stations.
