How secure are your Android smartphones?

Mobile devices can be highly insecure, particularly smartphones. Take Android for instance. When you buy an Android smartphone it’s rarely a pure Android experience. Manufacturers often try shipping smartphones with their own apps and services, or in other words, bloatware. But beyond the usual annoyance, these apps and services could be equipped with their own vulnerabilities. This essentially puts smartphones at risk prior to getting the devices to the users’ hands.
