Devices running on Android are at risk from the Heartbleed security flaw. Google says it only affects an older version of Android from 2012 but security experts estimate that this still leaves millions of handsets at risk.

The Heartbleed Detector app scans your phone for vulnerability. My HTC One Mini is affected by Heartbleed but it is not compromised. The app reminds you that if there are no updates there is nothing you can do, but the good news is that they have yet to see Heartbleed-related attacks targeting a mobile device.
