The list of Recent apps sometimes becomes unresponsive if the screen orientation is changed while the list is open. In some cases when entering and exiting Picture-in-picture (PiP) mode from an app after changing the screen orientation, the system Settings app crashes with a “Settings keeps stopping” message and then the system Settings app can’t be opened. An issue with the System UI can sometimes cause it to crash from a null pointer exception. 此訊息為錯誤問題
