iPhone Duo outer display swipe gesture fails to open Notification Centre

I am experiencing consistent difficulty opening Notification Centre on the outer display of my iPhone Duo. Swiping down from the top-left edge frequently fails to register, and on several occasions it has activated Siri instead of revealing notifications. In most cases I need to repeat the gesture several times before the system recognises it correctly.


A screen protector is currently fitted to the outer display, and I am unsure whether it is interfering with edge-touch detection. The gesture works reliably on the main display, which suggests the issue may be specific to the outer display, either through its gesture recognition or through the protector's effect on touches near the edge.

Hi there


Please try this

 A common workaround for the iPhone Duo is to map a double-tap on the back of the device to the Notification Centre. Go to Settings > Accessibility > Touch > Back Tap, and assign Double Tap to Notification Centre. 

AssistiveTouch: You can enable a floating software button via Settings > Accessibility > Touch > AssistiveTouch. Set the custom double-tap action of that button to open the Notification Centre.

Thank you for your reply and for the suggested workaround.


I would prefer not to change my Double Back Tap, as I use it to lock my phone. I would also rather not use AssistiveTouch, as I do not want an on-screen button permanently displayed.


My original question therefore still stands. When I perform [Pulling down from Top Left on outta screen], my phone opens Siri instead of the Notification Centre. I would like to know whether this could be a bug in iOS, with the gesture not being mapped correctly. As far as I understand, Back Tap and Siri are meant to operate independently, so this behaviour is unexpected.


Could you please advise whether this is a known issue and whether a fix is planned? If not, I would be grateful for any further guidance on how to resolve it without changing my Double Tap setting.
