Like the Apple iPhone 5 and the Samsung Galaxy S3, a lock screen workaround was discovered on the Sony XPERIA Z. This lockscreen bypass allows anyone who is knowledgeable about the process to access the phone’s contents without needing a passcode.
Scott Reed posted a video on YouTube showing how the workaround is done on the XPERIA Z. He demonstrates how to bypass the lockscreen by typing in a sequence of numbers. This makes a menu appear on the screen. Choosing a certain option unlocks the phone.
Unfortunately, Sony has not yet owned up to the problem. We hope they release an update that fixes the security flaw soon.
However, Sony did roll out an update, which fixes the sudden death issue of the XPERIA Z. Since they know about that issue, it’s safe to say that they know about this issue as well.
Bypassing lock screens without ever needing user-specific passcodes is not new. This is an issue if the Samsung Galaxy S3. Unfortunately, the Korean tech giant has not yet rolled out a fix to the problem.
This is the same case with Apple’s iPhone 5. The problem was discovered after the rollout of iOS 6.1.
Waiting for Sony to roll out an update that will fix lock screen bypass of the XPERIA Z? Keep it here for more updates.
