I am concerned that the phone will seemingly not allow you to combine the functionality of the lock screen with increased phone security. By default you open the lock screen by swiping. This however gives you low security. I tried entering a PIN code like on my old phone, and this gives you much greater phone security. However it also removes all of the functionality of the lock screen. You no longer have access to the lock screen short cuts that you have set up, and you no longer have the opportunity to open an incoming SMS for example direct from the lock screen. On my old phone (HTC Desire) you would have to swipe the screen and then enter the PIN code - admittedly the Desire had no additional lock screen functionality like the S3. The only lock screen shortcuts that I have are the camera and S-Voice, as these will not compromise my security. I don't understand why Samsung have enabled lock screen functionality only when combined with low to no security. Or have I missed something in the settings?
