The triple click accessibility shortcut is assigned to trigger the assistive touch icon , this works very rarely as intended and triggers the shut down screen.
I have tried assigning different shortcuts but it the shut down screen is always triggered.
On restarting the phone , it seems to work a few more times as intended , but then again reverts to the bugged state.
I have create a feedback (FB13459492) for this in December 2023 but haven't received any reply. Updated recently with a screen recording.
