Some apps3Dtouch in ios15.4 cannot slide

Use the small dot at the top of the Dock bar to switch the interface left and right, switch the main interface to the negative screen, and slide up from the bottom to return to the main interface to restore it.

One of the bugs in the iOS system will cause the desktop to freeze and prevent you from sliding left or right when the bug is triggered.

How to trigger: First, we swipe right on the main interface to enter the negative one-screen interface, then pull up, you will see an "Edit" button at the bottom, and click "Voice Microphone" and "Voice Microphone" in the upper right corner at the same time. "Edit" button at the bottom.

At this point, the system will jump to the voice search interface. At this time, we will slide up from the bottom to return to the main interface. You can no longer slide after returning to the main interface.
