Sony Xperia Z Bug Allows Easy Lock Screen Bypassing
Sony's latest smartphone, the Xperia Z, appears to have joined the ranks of Apple's iPhone and Samsung's Galaxy S3 as a newly discovered bug opens up a security flaw in the lock screen of the device.
A tech enthusiast named Scott Reed discovered the flaw on his personal Xperia Z and unlike the aforementioned devices, the method to unlock the Sony smartphone is easy. The new finding once again underlines the fact that lock screens are not absolutely safe and your sensitive data is not completely secure under a locked screen.
Reed has apparently managed to successfully bypass the lock screen of the device in just a few simple steps. Unlike the complex techniques employed in recent lock screen bypassing on Apple and Samsung devices, here the user has to pull up the emergency dial pad and just type in *#*#7378423#*#*, which will open up the service menu. At this point, one has to use the NFC > NFC Diag Test via service menu and press the home button that will provide access to the phone's home screen.
Although Sony has yet to acknowledge the bug, it has rolled out a fix for a bug that has caused some Xperia Z devices to randomly brick themselves.
