One of the most notable feature of latest Android 4.2 is the ability to put any of your widget straight to your phone’s lockscreen. Another was a way to access the camera directly, without unlocking. While these might sound like great features. This whole concept can be seen as a security issue too.
This can be overcome now an app was released to Google Play recently, named ‘Lockscreen Policy’. The app lets you disable the lockscreen widgets as well as the camera with just a couple of clicks. This app is totally free on Google Play.
