If I go to Settings/Security and Privacy/Lock Screen, the first option at the top of the screen is "Allow Power/Lock Key to Unlock Device". It doesn't matter whether the feature is on or off, if my device is locked, the only way I can unlock it is by putting in my password one letter at a time. Does anybody know how this option works, or is it another BB Classic mystery?
At first, it doesn't make sense, as tsac says. However, if one wanted to easily get by the password requirement while at home, it would make it easier to get past the password with one push. i.e. activate the option while at home; deactivate when away - just don't forget.
