BGR has discovered a pretty big security flaw in AT&T’s version of the Galaxy S II, which hits shelves tomorrow. For users who have a unlock pattern or pin set, they can simply bypass it by waking up their screen to unlock and then let the screen timeout to go black. Then simply, the user can wake up the phone once again and they’ll no longer have to use a pattern or pin to access the phone. BGR shows how simple it is in the video above.

Samsung offers a temporary work around, while they work on a permanent solution, after the break:

Samsung told BGR:

Samsung and AT&T are investigating a permanent solution. In the meantime, owners of the Galaxy S II can remedy the situation by re-setting their time-out screen to the “immediately” setting. This is done by going to the Settings ->Location and Security->Screen unlock settings->Timeout->Immediately.
