A new hack has been revealed which allows people to bypass a pin-secured lockscreen on Galaxy smartphones. Discovered by Terrence Eden who uncovered a Galaxy Note II security flaw earlier this month, by using a combination of keypresses and commands, someone can unlock the screen. The exploit comes from placing a failed emergency call where the screen is unlocked very briefly. On the flip side, Samsung is already working on a software fix and this hack only allows access for a very short period of time. Terrence uploaded a video to YouTube showing the hack which you can check out below. In the meantime, don’t leave your Galaxy smartphone just laying around.
