I've got 6.1.1 and 6.2 installed on a couple devices, and haven't noticed any difference in how the Notification Center is shown. I still need to do the swipe up gesture to show the hidden Notification Center.
One thing to note though is that the Notification Center will remain visible if you have swiped up previously to show it during your "unlock session". So say you swipe up to show your Notification Center (and leave it shown)...do stuff in other apps...it'll continue showing every time you swipe down as long as you don't lock your phone or hide it again. Once you lock your phone, it gets hidden and you need to do the swipe up gesture again. It has always been this way and
post #18 probably explained it better than I did. Could that be what's causing your inconsistent behavior?
Nope, this is the tested workflow:
- Phone is locked, screen is off
- Raising it (I use Raise to Wake), screen is on, FaceID doing its job, no notifications at all on the LockScreen
- Swiping up from the bottom bar to go to the Home Screen, a subtle vibration occured and I can see that the Notification Centre unhide at this precise moment from a few frame before the Home Screen unlock animation
- Swiping from top of the screen: Notification Center is already unhidden with few notifications.
But this does not occurs 100% of the time even if Notification Center has few notifications remaining in it. I really think it's a bug between the swipe up from the bottom bar to go to the Home Screen and the swipe up from the middle of the screen to open the Notification Centre. Both seems to be registered as user input, at the same time, in this case.
I did a intense lock/unlock test with a remaining notification in the Notification Centre, and I can reproduce it 1/3 of the time positively (Notification Centre auto-unhidden).
I'm sorry I can't do a video about this because if I launch a Recorded Screen session, the recording automatically ends when I lock the phone...
EDIT: In fact, if this "bug" was 100% reproductible, I will love how it acts 😅.
