iPhone Duo experiences intermittent touchscreen unresponsiveness and lag

Hi everyone,


I recently got my new iPhone Duo, and I’ve been experiencing a strange, intermittent touchscreen issue.


Sometimes the touchscreen suddenly stops responding properly, or scrolling becomes noticeably laggy, inconsistent, or completely unresponsive.


Here are some details:



  • It happens on both the inner display (unfolded) and the outer display (folded).


  • It can happen randomly in different apps, including Apple’s own apps.


  • Sometimes certain buttons or areas of an app continue responding normally, while others completely ignore my touches.


  • For example, in the Files app, I might still be able to interact with certain elements, but the Back button suddenly stops responding. This is just one example; it can happen with different buttons or gestures in any app.


  • Scrolling sometimes feels delayed, stutters, or stops responding as expected.


  • It almost feels like the interface is freezing, but it doesn’t appear to be a complete system freeze because other touch interactions still work.


  • The issue is intermittent and doesn’t seem tied to a specific application or to whether the phone is folded or unfolded.

I’m wondering whether this could be an iOS 27 software issue, a touchscreen responsiveness bug, or something related to the iPhone Duo’s new display system.



I’d particularly like to know whether this is affecting other devices or whether my unit might have a hardware defect.


Hopefully Apple can investigate this if more users are experiencing the same behavior.


Thanks!
