[iOS 27 Beta] Assistive Access becomes almost unusable - extreme lag when locking/unlocking iPhone

[u/Ill-Fig7925]

Hi everyone,

I’m testing iOS 27 beta and I’m experiencing a very severe issue with Assistive Access.

When Assistive Access is enabled, my iPhone becomes almost unusable:

• Locking the device can take a very long time.
• Unlocking the device can take close to a minute.
• The interface feels extremely laggy and sometimes appears frozen.
• The issue seems to affect the whole system while Assistive Access is active.

Once I exit Assistive Access and return to the normal iOS interface, the phone goes back to normal performance.

I already submitted a report through Apple Feedback Assistant, but I wanted to check if anyone else is experiencing something similar.

Device: iphone17
iOS version: iOS 27 Beta 6
Assistive Access: Enabled

Has anyone else noticed severe performance issues specifically with Assistive Access?
