Got a Galaxy S III? Well you should know that a newly discovered bug could let someone bypass the lock screen and access your device.  Discovered by Sean McMillan, the bypass involves a few timed button presses to gain access to the S III’s home screen. It seems the bug only works on S III devices running Android 4.1.2.

If you want to see if your phone has the same vulnerabilities, the instructions to start up the vulnerability are as follows:

  1. Press the Emergency Call button on the code entry screen.
  2. Press Emergency Contacts
  3. Press the Home button once
  4. After pressing the Home button, press the power button quickly
  5. If successful, pressing the power button again will give you access to the home screen

It takes a bit of patience to get the bug working and seems to work better when auto-rotation is turned on. You may have to try the bug a few times, McMillian had more than 20 attempts. This bug follows the discovery of the iOS 6.1 lock screen bug. It seems these bugs share similarities in how they’re accessed so you could fiddle around on your own phone and stumble onto a bug.
