Lock screen security flaws have been popping up a lot in recent weeks, with newly discovered bugs affecting the Samsung Galaxy S III, the Galaxy Note II, and even Apple’s iPhone 5. Now the new Sony Xperia Z has one of its own, and it’s a pretty serious one.

By typing a simply series of digits, anyone can bypass your lock screen security and gain full access to your device. Check out the video below.

Sony unveiled the Xperia Z, its latest flagship smartphone, at the Consumer Electronics Show in Las Vegas last week, and the device has been very well received. It looks good, and it has some great specifications. But there was one thing we didn’t like. The device is set to launch with Android 4.1 Jelly Bean — not Android 4.2, the latest release, which offers features like Daydream and lock screen widgets.

Thankfully, Sony has now confirmed that the Xperia Z will get the Android 4.2 update “shortly after launch.”
