Samsung Galaxy S III flaw bypasses lock screen (again)
posted by Nick T. / Mar 07, 2013, 2:00 AM
Several days ago, a flaw in the Samsung Galaxy S III interface was discovered allowing access to the phone's home screen even when a PIN or pattern lock screen was enabled. That hack, however, didn't seem as much of a threat given how little time one had to actually do something naughty with the targeted device. Yet now, another vulnerability that works in a similar fashion has been found and it pretty much bypasses the lock screen indefinitely. And that's a pretty serious privacy concern.
Samsung Galaxy S III home screen.Here's how the hack works: from the lock screen press the "Emergency Call" button at the bottom. Then quickly press the emergency contacts button (bottom left), then the home button and then the lock key. If done properly, the next time the lock key is pressed it will take you to the
Note that this hack does not work every time. First time we tried bypassing our Galaxy S III lock screen it took us about 10 minutes of trying. But then we got the hang of it and managed to hack it within 10 attempts. Also, the one who discovered the vulnerability notes that having screen auto-rotation enabled increases the chances of the hack to work. Strangely, although the hack gives access to all apps and home screens, the notification bar remains inaccessible. This flaw appears to affect Samsung Galaxy S III units running Android 4.1.2. (UPDATE: Samsung Galaxy Note II is vulnerable as well.)
So all of you, guys, holding on to a Samsung Galaxy S III protected by a PIN or pattern, keep in mind that it isn't as secure as it should be. Hopefully, Samsung will address the issue in a timely manner.

were GS3 owners feeling left out because iPhone users were having the problem or was iPhone users jealous of GS3 users cos they didnt have the problem?

"Note that this hack does not work every time. First time we tried bypassing our Galaxy S III lock screen it took us about 10 minutes of trying.

looks like android community was having fun with Apple while they had the same flaw.

How do people find this? Do they have this much free time in the day to try all aspects of bypassing lock screens on phones? This goes to the iPhone one too. That one was complicated and was found days after 6.1 rolled out.

Looking forward to the Note III, I'm still loving my updated Original Galaxy Note... Never was a fan of the S series, so sorry it has that problem... It's "Note" or bust for me, Okay i'm lying... I'm gonna pick up a fiberglass iphone too. To the OEM fix these problems please. :/

My cousin is a genius when it comes to getting by people's lock screen. He's been doing it long before I ever heard about on sites like PA. Lil' bastid then likes to send embarrassing messages to people, nothing more nefarious than that though at least. Because of him, I downloaded an app called App Lock. Even if he gets past the lock screen there's nothing he can do about the 2nd (different) pass code which doesn't seem as exploitable as a lock screen. Not an advert for App Lock, just the one I happen to use. It just works well enough for me that because I have access to contacts, photos, calling, Play Store, etc. blocked off that I don't even bother with the lock screen anymore.

Sorry - got nothing to hide on my SGS3. And it's always with me at all times regardless. Not to mention you got a gazillion apps to password lock your access to apps and what not.

Samsung will do nothing as all their attention is on the upcoming release of the highly hyped Galaxy 4 and don't have time for a s3 being on life support... Same fate of the s2 last year.

What you just said makes absolutely no sense. The S2 never suffered at any such fate a year ago. It just received Jellybean. Does an almost 2-year old phone on "life support" receive a new operating system? No. Also, it was the highest selling Android phone of all-time before the S3. Now that the S3 is the highest selling Android of all-time, you can believe it will get the same or even better support in the future. It already went from 4.0 to 4.1. They'll squash this bug, then soon it will get 4.2. There's no doubt in my mind that it will see 5.0 in the future, too.

Calling all the fandroids that mocked Apple when PA posted the lockscreen bypass. Please point at yourself in the mirror and laugh. http://www.phonearena.com/news
