The iPhone isn't the only mobile device that can have its lock screen bypassed with some key button presses and good timing: the lock screen on Samsung's Galaxy S III can be bypassed as well.
As discovered by Sean McMillan and posted to the Full Disclosure mailing list, a user can bypass the Galaxy S III's lock screen with just a few button presses, with the right timing,
McMillan tested his bypass method on a variety of different Galaxy S III devices. Mashable was able to successfully unlock a Galaxy S III running Android 4.1.2 using McMillan's instructions, as were other outlets including The Verge and ZDNET.
However, just as the iOS lock screen vulnerability is difficult to do, bypassing the lock screen on the Galaxy S III takes precision and good timing. It took me over 10 minutes to get past the lock screen successfully for the first time and my luck wasn't better in subsequent sessions.
Unlike the iOS bug, this method provides full access to the phone without requiring the use of iTunes and a USB connection. In other words, if you can get the timing correct, this method -- which uses the emergency call functionality in the Galaxy S III's dialer -- unlocks the phone full-stop.
Samsung has not responded to a request for comment.
