My iPad no longer has a flashlight option. It’s not in the control center or quick options
I used to have a flush light. When I ask Seri to turn it on she now says Tourch is not available. What happen to it?
You haven’t told us what model of iPad you have. Anyway, if the Flashlight feature is supported by your iPad, it is accessed from the Control Centre.
Swipe-down from the top-right of the screen, the then tap the Flashlight icon to switch on or off. To change brightness, touch and hold the Flashlight icon.
Only those models of iPad that are fitted with a TrueTone flash (iPad mini6 and iPads Pro) have a flashlight control in the Control Centre.
