Hello all, after I do a soft reset to my lumia 820 when the phone asks for pin code for sim card I accidentaly press the back button for a few seconds and as you may guess the main screen comes smaller like when you want to select an app runs in background. Then I again tap to screen and I saw that it does not ask for a pin code and goes to the start screen. Could you try this for yourself and share your opiniom whether there is a problem?
