Whether I go through settings or long press the lower right buttons to bring up the Lock Screen settings - and whether I have widgets enabled or not, I have no shortcuts on the lock screen.
If I go to "Shortcuts" I see an image of my lock screen with a clock/date on it. Below it are 5 icons with a "settings gear" on their top right corners. If I click one I can pick a different app. I can save and change them.
However, the ACTUAL lock screen only has the time/date, a "square" area (outlined at 4 corners, about 1/3 of the size of the screen) and at the bottom is the Emergency call button.
One time, and I dunno how - I did see the correct lock screen shown. Why does it always show this "Emergency call" version instead?
