You can swipe to the right on the unlocked home screen to get to the widgets.
I know that. Default settings I do this.
Press home (phone is locked)
Swipe right for widgets
Scroll down for activity widget
Tap home button to "unlock" phone
The phone will jump to home screen
Then I'll press the lock button and try the exact same thing. But this time it will stay in the lock screen and show the activity data. It's inconsistent and that's the issue. Doesn't happen very often, maybe 1-2 every 10 times. But it's annoying enough.
