Galaxy S III is Also Vulnerable to "Cheat Style" Unlocking Hack

Five step hack allows you to easily avoid password on top Android smartphone
Apple, Inc. (
) recently was heavily criticized when hackers discovered a complex process of presses allowed a potentially malicious user to
circumvent the lock screen password
. The "hack" resembled a video game cheat and was quite intensive.
But apparently Apple wasn't the only one with this kind of vulnerability (or perhaps a backdoor firmware makers forgot to remove?). With Android smartphones, Google Inc. (
) typically allows Android phonemakers to make their own lockscreens. Due to legal issues with Apple, and the desire to have distinctive GUIs, Android phonemakers have a variety of different software handling unlocking.
In Samsung's case, the proprietary lock-screen implementation on its best-selling flagship Galaxy S III is vulnerable to a similar hack.
The Full Disclosure
mailing list, a popular hardware and software hacking email mailer, reveals the process as:
1) On the code entry screen press Emergency Call
2) Then press Emergency Contacts
3) Press the Home button once
4) Just after pressing the Home button press the power button quickly
5) If successful, pressing the power button again will bring you to the S3′s home screen
Looks like for now Samsung owners might want to avoid hurling criticism at Apple for its similar backdoor.

I've just tried this on my phone and can't replicate it.
It's possible that as I've enabled the option to have the power button lock the screen automatically it stops the exploit (or it could be I'm using a Samsung based custom ROM).
Settings->Lock Screen then enable "Lock instantly with power key".
If you want to set security on your phone why not enable this as well.

Mine is set to 5 seconds. I changed it to 1 minute and still can't replicated it. I am using stock with root access.
