Android 5 lock-screens can be bypassed by typing in a reeeeally long password. In 2015

f you’ve got an Android 5.0 smartphone with anything but the very latest version of Lollipop on it, it’s best to use a PIN or pattern to secure your lock-screen – because there’s a trivial bypass for its password protection.

The vulnerability, published here by University of Texas researchers, allows miscreants to sidestep lock-screens on Android 5 devices, unless they’ve been fully patched to version 5.1.1 including last week’s security updates.
