There is no doubt that Android is the best OS in the world, but it isn’t without its problems. From time to time, you’ll be faced with an issue that is you can’t get your head around, and you need some help to figure it out. For example, the recently discovered lock screen vulnerability in the Samsung Galaxy S3 and the Sony Xperia Z.

As you known by all, the most important as well as the most basic security function in a smartphone is its screen lock, which protects the device from unauthorized access. However, the recently discovered vulnerability in the Galaxy S3 and the Xperia Z makes it easy to break this security mechanism and access the device and all data stored on it with a simple trick.

Luckily, there are thousands of tools and utility available at Google Play Store to help you quickly solve any problem you face and you don’t need to be a technical genius to use them. For example, the lock screen vulnerability can be easily solved with the G Data MobileSecurity 2.

G Data MobileSecurity 2 (paid) is a comprehensive security software for Android smartphone that provides real time protection against mobile malware and internet threats as well as blocks annoying callers and SMS senders.


The lock screen vulnerability can be easily eliminated with this tool. Affected users can try a 30-day trial version (available at: http://qsmirror01.gdatasecurity.de/qs/MOBILE/30days/INT_M_TRL_30days_MS2_R_2013.apk) of G Data Mobile Security 2.
