If you don't find that then try looking for quick settings developer tiles...turn on sensors and then pull down the notifications panel
After u get there u have to switch off "turn off sensors"
That will fix it
You are correct; that is the problem some users may have set-up the Quick Panel button to switch the sensors' off or on, which was recommended by a YouTuber. When created, the controller button is in the top left corner of the first page, easily activated accidentally.
The recommendation is to move this button to page 2 or 3.
