Resolved Issues

Table 3 Resolved issues

Issue No. Issue
7475 During XTS testing, a callback (a local function of a case) registered with on was not unregistered with off. Later cases triggered this callback, but it failed due to the referenced JS function being destructed, causing test failures.
1523 During XTS testing, the ActsTelephonyContactTest suite failed due to a timeout when the contact service of the RK3568 development board accessed datashare.
5686 During XTS testing, the service code of asset creation APIs was not distinguished, leading to test failures.
569 The com.ohos.systemui process frequently freezes due to INPUT_EVENT_SOCKET_TIMEOUT.
1514 The OS_IPC_1_743 thread in the /system/bin/bootanimation process occasionally crashes due to libaccessibilityconfig.z.so crashing.
513 The OS_IPC_6_979 thread in the foundation process rarely crashes due to libhilog.so crashing.
