DzLock is not just an ordinary lock app but it’s a sensor based app from Dzybba. No more fancy graphics on screen but still a fun way app in your Symbian phone. It uses the proximity sensor on the phone. So by just tapping twice the sensor brings lock and unlock mode, vice versa.
It’s free from Ovi Store and it would support touch devices of Symbian that has proximity sensor like the Nokia N97 and Nokia E7. Watch the demo below.
