Here’s a look at the key specs of the Xperia Z: It is powered by the ultra-fast Snapdragon S4 Pro SoC, which has four Krait cores clocked at 1.5GHz besides an Adreno 320 GPU. Firstly, the handset is water and dust-proof and comes in a 7.9mm-thin body. Despite the lockscreen flaw, the Xperia Z remains a formidable Android smartphone with some eye-catching features.

Let’s hope that this one is fixed in a jiffy too. The company yesterday issued the first firmware update for the phone, which fixed a ‘sudden-death’ issue that plagued some devices. Sony has been rather quick with bug fixes for the Xperia Z. In any case, that’s a major security flaw and potentially allows anyone to access apps, write on the memory card or see your personal information. We're guessing this is a bug left over from the development table as it makes it easier to test the various sensors. After the test is done, just hit the home button from the on-screen navigation bar and you'll be taken straight to the homescreen without any passcode required. Find the NFC setting and trigger a NFC diagnostic test. That USSD serves to open up a various services menu that lets you view the status of the various sensors in the phone.

If you want to reproduce the bug, all you have to do is feed in the USSD code *#*#7378423#*#* on the phone’s emergency dialer. In fact, this lockscreen bypass is one of the easiest we have seen, as is evident in a video posted by YouTube user Scott Reed. After recent instances of the iPhone 5, Samsung Galaxy S3 and Galaxy Note 2 being intruded on despite a passcode or a security pin, it’s now the turn of Sony’s Xperia Z.Īpparently, the Xperia Z’s lockscreen is so broken that it gives anyone access to anything they want to explore on the phone, except for resetting the passcode, pin or unlock pattern. If you're a top smartphone manufacturer and are shopping for features to be included in your next high-end phone, here’s a tip: don’t ship it with a buggy lockscreen.
